Atom was officially sunset by GitHub in December 2022 and is no longer maintained. To use Bolt.new code outside the browser, export your project as a ZIP and open it in VS Code (Atom's actively maintained successor) or Pulsar (the community fork of Atom). The export workflow takes under five minutes and gives you full local development capabilities.
Using Atom or Pulsar with Bolt.new Exported Projects
Atom was one of the most popular open-source code editors before GitHub announced its sunset in June 2022, with the service officially shutting down on December 15, 2022. If you are still using Atom in 2026, you are almost certainly running Pulsar — the community-maintained fork that picked up where GitHub left off. Pulsar maintains compatibility with Atom's package ecosystem and configuration format, so anything in this guide applies to both.
Bolt.new runs entirely in your browser using WebContainers, a WebAssembly-based Node.js environment. Everything you build in Bolt stays inside that browser tab — there is no connection between Bolt and a locally installed editor. To work on your Bolt code in Atom or Pulsar, you need to export the project first. Bolt generates standard Vite or Next.js projects with a proper package.json, so the exported code works in any editor without modification.
For most Bolt users considering Atom, the honest recommendation is to migrate to VS Code instead. VS Code is actively maintained by Microsoft, has a far larger extension ecosystem, includes an integrated terminal, and has native Git integration that pairs well with Bolt's GitHub push feature. However, if you have an existing Atom or Pulsar setup with custom configuration that would take time to replicate, the export workflow described below works perfectly well — Atom and Pulsar can open, edit, and run Bolt-generated projects without any special setup.
Integration method
Bolt.new has no native Atom integration and Atom itself is no longer maintained. The workflow is a manual export: download your Bolt project as a ZIP file, extract it to a local folder, and open that folder in Atom or its community fork Pulsar. Because Bolt generates standard Vite or Next.js projects, any text editor that understands JavaScript and TypeScript will work without modification. For most users, migrating to VS Code is the recommended path.
Prerequisites
- A Bolt.new account with an active project ready to export
- Atom installed (download the last official release from atom-editor.cc) or Pulsar installed (pulsar-edit.dev — the actively maintained community fork)
- Node.js 18 or later installed locally to run the exported project's dev server
- A terminal application (Terminal on macOS, Windows Terminal, or your preferred shell)
- npm or pnpm installed globally for running the project after extraction
Step-by-step guide
Understand the Atom Situation and Choose Your Path
Understand the Atom Situation and Choose Your Path
Before setting up the workflow, it is worth understanding what 'Atom' means in 2026. GitHub officially sunset Atom on December 15, 2022 — the official download links now redirect to Pulsar (pulsar-edit.dev), a community fork maintained by volunteers that preserves the Atom experience and package ecosystem. If you downloaded Atom after early 2023, you likely installed Pulsar. The original Atom binaries are still available on atom-editor.cc, a community archive site, but they receive no security updates or bug fixes. Your options are: (1) Use Pulsar — the direct Atom successor, actively maintained, fully compatible with Atom packages and config. This is the best choice if you want the Atom experience with ongoing support. (2) Use VS Code — Microsoft's editor that shares Electron foundations with Atom, has absorbed much of the community, and offers superior extension support and performance. (3) Continue with the original Atom binary if you already have it installed and it meets your needs, understanding that it is frozen at the December 2022 state. For this guide, the steps apply to both Atom and Pulsar identically — the editors share the same interface, keybindings, and package manager (apm for Atom, ppm for Pulsar). When a command differs, both versions will be shown. Regardless of which editor you choose, the Bolt.new export workflow is the same: Bolt generates a standard JavaScript project, and any text editor can open and work with it.
Pro tip: If you are evaluating whether to migrate from Atom to VS Code, note that VS Code can import your Atom keybindings through the 'Atom Keymap' extension in the VS Code marketplace, making the transition significantly smoother.
Expected result: You have a clear understanding of which editor you are using (Atom, Pulsar, or VS Code) and are ready to export your Bolt project.
Export Your Bolt Project as a ZIP
Export Your Bolt Project as a ZIP
Bolt.new does not have a direct 'open in editor' integration for Atom or any local IDE. The connection point is the project export feature, which downloads all your project files as a ZIP archive. This is the standard path for working on Bolt code outside the browser. To export: open your Bolt project in the browser, look for the download icon in the top toolbar (it typically looks like a downward arrow or a box with an arrow). Click it — Bolt packages your entire project file system into a ZIP and downloads it to your browser's default download folder. The ZIP contains all project files: package.json, the src/ directory with all components, configuration files (vite.config.ts or next.config.js), .env (if you created one with placeholder values), and the public/ directory with static assets. Important notes about the exported ZIP: the node_modules/ directory is NOT included in the export (this is correct behavior — running npm install after extraction will recreate it). If you used Bolt's Secrets management, those secrets are also not exported — you will need to recreate the .env file locally using the same key names with your actual values. The export captures the current state of the project at the moment you click download; any subsequent changes made in Bolt will require a new export. Create a dedicated folder on your machine for Bolt projects — something like ~/projects/bolt-exports/ — and extract each project into its own named subfolder. This makes it easy to manage multiple exported projects and understand which export corresponds to which Bolt project.
1# After extracting the ZIP, install dependencies:2cd ~/projects/bolt-exports/your-project-name3npm install45# Verify the project structure looks correct:6ls -laPro tip: Export your Bolt project to GitHub first (using Bolt's built-in Git panel), then clone the repository locally. This approach gives you a persistent copy that you can sync with Bolt rather than managing ZIP archives.
Expected result: Your Bolt project is extracted to a local folder with all source files present. The node_modules/ directory is absent until you run npm install.
Install Essential Packages in Atom or Pulsar
Install Essential Packages in Atom or Pulsar
Fresh Atom and Pulsar installations lack built-in support for TypeScript syntax highlighting, Tailwind CSS class autocompletion, and ESLint integration — all of which Bolt.new projects use heavily. Installing the right packages significantly improves the editing experience. To install packages in Atom: go to Edit > Preferences (or Atom > Preferences on macOS) > Install, then search for and install each package. In Pulsar, the menu path is Pulsar > Preferences > Install. The package manager command line also works: for Atom, use `apm install package-name`; for Pulsar, use `ppm install package-name`. Essential packages for Bolt-generated Vite/React/TypeScript projects: - **atom-typescript** (Atom) or **pulsar-typescript** (Pulsar): Full TypeScript language support including type checking, go-to-definition, and rename refactoring. This is the most important package for Bolt projects. - **language-babel**: Enhanced syntax highlighting for JSX and modern JavaScript/TypeScript. Handles React component syntax better than the default language-javascript package. - **linter** + **linter-eslint**: Displays ESLint errors inline in the editor. Bolt projects include an ESLint configuration that linter-eslint will automatically use. - **autocomplete-paths**: Improves path autocomplete for imports — useful when manually adding imports to Bolt-generated components. - **tailwind-css-autocomplete** or **autocomplete-tailwind** (search the package registry for current Tailwind v3 compatible versions): Adds autocomplete for Tailwind CSS classes in JSX className attributes. - **prettier-atom**: Automatic code formatting using Prettier. Bolt's generated code is already well-formatted, but this helps maintain consistency when you add code manually. After installing these packages, close and reopen Atom/Pulsar for all packages to initialize correctly. Open a .tsx file from your Bolt project to verify syntax highlighting is working.
1# Install core packages via command line (Atom):2apm install atom-typescript language-babel linter linter-eslint autocomplete-paths prettier-atom34# For Pulsar:5ppm install pulsar-typescript language-babel linter linter-eslint autocomplete-paths prettier-atomPro tip: The atom-typescript package for Atom requires TypeScript to be installed in the project's node_modules. Run npm install first so atom-typescript can find the correct TypeScript version for your project.
Expected result: TypeScript files (.ts, .tsx) show syntax highlighting and type error indicators. ESLint violations appear as inline warnings. Tailwind class names show autocomplete suggestions.
Run the Bolt Project's Dev Server Alongside Atom
Run the Bolt Project's Dev Server Alongside Atom
Unlike VS Code, which has an integrated terminal, Atom and Pulsar require a separate terminal window to run the project's development server. This is a minor workflow difference but important to understand — you will work with two windows open simultaneously: the editor and a terminal. Atom does have a terminal package called **platformio-ide-terminal** (Atom) or the equivalent in Pulsar's package registry, which adds a terminal panel at the bottom of the editor window. This is the closest experience to VS Code's integrated terminal. Search for it in the package manager under Edit > Preferences > Install. If you prefer a standalone terminal, that works equally well. To start the dev server: open your terminal, navigate to the extracted Bolt project folder, and run the appropriate start command. For Vite-based Bolt projects (the default), that is `npm run dev`. For Next.js projects, it is also `npm run dev`. Both will start a local development server, typically at http://localhost:5173 (Vite) or http://localhost:3000 (Next.js). An important WebContainer limitation to be aware of: Bolt's browser-based preview works because WebContainers virtualize a network stack inside the browser. Your locally exported project uses a real Node.js server on your machine, which behaves differently in some ways. Specifically: any API routes in the project that make outbound HTTP calls will now work via real network connections (no CORS or WebContainer restrictions), but the local .env file must have real API keys — Bolt's Secrets tab values are not exported. Create a .env.local file alongside the project's .env file to store your actual development credentials without committing them to Git. When you are satisfied with local edits, you have two options for getting changes back to Bolt: push to GitHub (if you connected Bolt to a repository) and then pull in Bolt's Git panel, or copy modified file contents back into Bolt's editor manually using the Dev Mode (paid feature).
1# Navigate to project and start dev server:2cd ~/projects/bolt-exports/your-project-name3npm run dev45# Create local environment file (never commit this to Git):6touch .env.local7# Add your actual API keys:8# VITE_SUPABASE_URL=https://your-project.supabase.co9# VITE_SUPABASE_ANON_KEY=your-actual-anon-keyPro tip: Add .env.local to your .gitignore file if it is not already there. Bolt's default .gitignore excludes .env but may not exclude .env.local — verify before your first git push.
Expected result: The dev server starts and the project is accessible at localhost:5173 or localhost:3000. Changes you save in Atom are reflected immediately in the browser via hot module replacement.
Sync Changes Back to Bolt via GitHub
Sync Changes Back to Bolt via GitHub
Working in Atom creates a local copy of your Bolt project that diverges from what is in the Bolt browser environment. To synchronize these changes, the recommended approach is using GitHub as the intermediary — the same approach used for all non-native IDE integrations with Bolt. If your Bolt project is already connected to a GitHub repository (via Bolt's Git panel > Push to GitHub), the workflow is: make edits in Atom, commit and push to GitHub using the terminal or a Git GUI client, then pull the changes in Bolt using the Git panel's pull option. Bolt will update its file system to match the GitHub repository state. If your Bolt project is not yet connected to GitHub, set it up now: in Bolt, open the Git panel, connect your GitHub account if not already connected, and push the project to a new repository. Then on your local machine, replace the ZIP-extracted folder with a proper Git clone of that repository. From this point forward, you have a clean bidirectional sync path: Bolt pushes to GitHub → you pull locally → edit in Atom → push to GitHub → Bolt pulls. A few important considerations for this workflow. Atom does not have built-in Git UI beyond syntax highlighting for diff markers — you need a separate Git client. Options include: using the terminal with standard git commands, installing the **git-plus** package for Atom (adds Git commands to the command palette), using GitHub Desktop (a GUI client that works alongside any editor), or using the **GitHub for Atom** package (note: this package received no updates after the Atom sunset and may not work correctly in Pulsar). The simplest path is using the terminal for Git operations while editing in Atom. Another consideration: Bolt's AI assistant is context-aware only of what is currently in the Bolt project file system. When you pull changes from GitHub into Bolt, the AI will see your Atom-made edits on subsequent prompts. This makes the hybrid workflow viable — Atom for complex refactoring, Bolt for AI-assisted feature additions.
1# After editing in Atom, push changes to GitHub:2cd ~/projects/bolt-exports/your-project-name3git add .4git commit -m "Refactor: improve component structure after Bolt export"5git push origin main67# Then in Bolt's Git panel, click Pull to sync these changes into BoltPro tip: Install the 'git-diff' package in Atom to see inline Git diff indicators (green for added lines, red for removed) in the editor gutter. This makes it easier to track what changed since your last commit.
Expected result: Your Atom-made changes appear in the GitHub repository and are pulled into Bolt's file system. The Bolt AI assistant can now build on top of the changes you made in Atom.
Common use cases
Quick Code Review and Edits in a Familiar Editor
After building a prototype in Bolt, export the project to review the generated code in Atom before deploying. Atom's multi-cursor editing and split-pane view make it easy to review multiple files side by side. Make targeted edits, then push changes back to GitHub for deployment.

Migrating from Atom to Pulsar While Keeping Your Bolt Workflow
Teams using Atom-compatible tooling can transition to Pulsar without disrupting their Bolt-based development process. Export from Bolt, open in Pulsar, use familiar Atom packages like linter-eslint and language-typescript, and push to GitHub with the same workflow.

Lightweight Editing of Bolt Exports on Older Hardware
On machines where VS Code is slow or memory-constrained, Atom and Pulsar offer a lighter-weight editing experience. Export your Bolt project, open it in Atom/Pulsar, and make focused edits to CSS, content, or configuration without the overhead of a full IDE.

Troubleshooting
TypeScript errors everywhere in Atom after opening the exported Bolt project
Cause: The atom-typescript package cannot find the TypeScript compiler because node_modules/ has not been installed yet, or the package needs to be pointed to the project's local TypeScript version.
Solution: Run npm install in the project directory first, then restart Atom. The atom-typescript package looks for TypeScript in the project's node_modules/typescript/ folder. If errors persist, open Atom's settings for atom-typescript and ensure 'Use bundled TypeScript' is unchecked so it uses the project's version.
1# Run in the project directory before opening in Atom:2npm install3# Then restart Atom and reopen the project folderThe dev server starts but API calls fail with CORS errors or missing credentials in the local environment
Cause: Bolt's Secrets (API keys stored in the Secrets tab) are not exported with the project ZIP — only the code that references them is exported. The local .env file has placeholder values or is missing entirely.
Solution: Create a .env.local file in the project root with your actual API keys. For Vite projects, prefix client-side variables with VITE_. For Next.js, use NEXT_PUBLIC_ for client-side variables. Note that unlike Bolt's WebContainer environment, the local dev server can make outbound API calls directly without CORS issues — so any CORS workarounds you added in Bolt may be unnecessary locally.
1# Create .env.local with real values:2VITE_SUPABASE_URL=https://yourproject.supabase.co3VITE_SUPABASE_ANON_KEY=your-real-anon-key4VITE_API_KEY=your-real-api-keyPulsar crashes or freezes when opening large Bolt projects
Cause: Large Bolt projects with many files in node_modules/ or dist/ cause Pulsar's file tree and indexing to consume excessive memory. Pulsar indexes all files in an opened folder by default.
Solution: Add the dist/, node_modules/, and .next/ directories to Pulsar's ignored directories list. Go to Pulsar > Preferences > Core Settings > Ignored Names and add these patterns. Alternatively, add them to the .gitignore file — Pulsar respects .gitignore for file tree exclusions when the tree-view package is configured to do so.

- Migrate to Pulsar rather than continuing with the original Atom binary — Pulsar receives security updates and bug fixes while the official Atom is frozen at December 2022.
- Use GitHub as the sync layer between Bolt and your local Atom/Pulsar environment rather than manually copying files — this creates a full Git history and enables clean bidirectional updates.
- Run npm install immediately after extracting the Bolt project ZIP before opening in Atom, so TypeScript packages can find the correct compiler version.
- Create a .env.local file for real API keys in the local environment and verify it is excluded from Git — never commit actual credentials to version control.
- Consider installing the platformio-ide-terminal package to get a terminal panel inside Atom/Pulsar, reducing context switching between the editor and a standalone terminal window.
- For teams with existing Atom workflows, evaluate VS Code as a migration target — it imports Atom keybindings via the 'Atom Keymap' extension and offers better TypeScript and Git integration for Bolt-generated projects.
- Keep Bolt exports organized by naming folders with the date and project name (e.g., bolt-export-2026-04-22-my-app) to track which export corresponds to which Bolt version.
Alternatives
VS Code is the actively maintained successor to Atom in spirit, with a vastly larger extension ecosystem, built-in Git UI, and integrated terminal — making it the recommended upgrade path for Atom users working with Bolt exports.
Sublime Text is a lightweight, fast editor that works well for editing Bolt exports on older hardware or when you want a minimal, distraction-free environment without an IDE's overhead.
IntelliJ IDEA (and WebStorm for JavaScript/TypeScript specifically) provides the deepest IDE features for Bolt-generated projects — advanced refactoring, built-in database tools, and superior TypeScript support compared to Atom.
Rather than replacing Atom with another editor, connect Bolt directly to GitHub and use Git as the bridge — push from Bolt, pull locally into any editor including Atom, and push changes back.
Frequently asked questions
Can I connect Atom directly to Bolt.new without exporting a ZIP?
No — Bolt.new has no native integration with Atom or any local IDE. The only way to work with Bolt code in Atom is to export the project as a ZIP file and open the extracted folder locally. For a more seamless workflow, connect your Bolt project to GitHub first, then clone the repository locally and open it in Atom — this gives you a proper Git-based sync path instead of managing ZIP archives.
Is Atom still safe to use in 2026?
The original Atom editor is frozen at its December 2022 state and receives no security updates. While the editor itself is not a direct security risk for most use cases, its dependencies (Electron, Node.js bundled with Atom) are outdated and may contain known vulnerabilities. Pulsar (pulsar-edit.dev) is the actively maintained community fork that updates these dependencies. For new setups, Pulsar is the safer choice — it is functionally identical to Atom but maintained.
Do Atom packages work in Pulsar?
Most Atom packages work in Pulsar without modification. Pulsar maintains a package registry that mirrors the Atom package repository and accepts uploads of updated packages. Some packages that relied on Atom-specific internal APIs may not work, but core development packages (language support, linters, formatters, Git integration) are generally compatible. Check pulsar-edit.dev/packages/ for the Pulsar-native versions of popular packages.
What happens to my Bolt project in the WebContainer when I edit it locally in Atom?
Nothing — your local edits do not automatically sync back to Bolt. The Bolt WebContainer is isolated in your browser and has no awareness of your local file system. To bring local edits back into Bolt, push your changes to GitHub and then use Bolt's Git panel to pull the latest changes. Without this sync step, Bolt and your local copy will diverge and the Bolt AI assistant will not be aware of your Atom-made edits.
Can I use Atom to test webhook integrations that don't work in Bolt's preview?
Yes — this is one of the key advantages of the local export workflow. Bolt's WebContainer cannot receive incoming webhooks because it runs inside a browser tab with no public URL. When you run the exported project locally with npm run dev and expose it with a tunneling tool like ngrok or Cloudflare Tunnel, you get a public URL that external services can call with webhooks. This lets you test Stripe webhook handlers, GitHub webhooks, and other event-driven integrations that are impossible to test in Bolt's browser preview.
