How to review code collaboratively in Replit

Click the Invite button in the top-right corner of your Replit workspace. Enter the email address or Replit username of each team member you want to add as a collaborator. On the Core plan, you can invite up to 5 collaborators. On Pro, up to 15 collaborators plus 50 viewer seats. Each collaborator gets full access to the workspace, including the ability to start their own Agent threads and review tasks on the shared board.

When collaborators work on features using Agent, each task appears on a shared Kanban board with four stages: Draft, Active, Ready, and Done. The developer moves their task to Ready when they want it reviewed. Another team member opens the task, reads the Agent-generated changes, and either approves (moves to Done and applies changes) or sends it back to Draft with feedback. This creates a natural review gate without any external tooling. Each task runs on an isolated copy of the project, preventing one person from accidentally overwriting another's work.

Open the Git pane from the Tools dock on the left sidebar (or search for 'Git' in the search bar). The Git pane shows all changed files with visual diffs — green highlights for additions, red for deletions. Before committing, click each changed file to review the diff line by line. This is your checkpoint to catch unintended changes, verify that Agent did not remove existing code, and ensure the changes match the intended feature. Stage only the files you want to commit by checking the boxes next to each file name.

For teams that want formal pull request workflows, connect your Repl to GitHub. Open the Git pane, click 'Connect to GitHub,' and follow the OAuth flow to authorize Replit. Select an organization and create a new repository. Once connected, push your code to GitHub. Team members can then create branches in Replit's Shell, push them to GitHub, and open pull requests for formal review with inline comments and approval requirements.

1# In Replit Shell — create a feature branch and push it
2git checkout -b feature/new-dashboard
3# ... make changes ...
4git add .
5git commit -m "Add dashboard component"
6git push origin feature/new-dashboard

For real-time code reviews, have the reviewer open the same Repl while the developer walks through changes. Multiplayer shows each person's cursor position and active file in real time. The reviewer can click on any line to navigate to it, and both users can edit the same file simultaneously. Use the chat or video call (external) alongside Multiplayer to discuss changes. This is especially useful for complex features where a diff alone does not tell the full story.

Add a REVIEW.md file to your project root that documents your team's review standards. Include items like checking for unused variables, verifying secrets are not hardcoded, confirming the app builds without errors, and testing key user flows. This file lives alongside your code and serves as a reference during every review session. Reviewers can open it in a split pane while reviewing diffs in the Git pane.
