# Migrating Betty Blocks to Code: The Complete Playbook (2026)

- Tool: No-Code to Code Migrations
- Last updated: July 2026

## TL;DR

Betty Blocks launched a React + WebAssembly export claim in 2025–2026, but this has not been independently verified as of July 2026. Pre-2025 apps have no code export — treat as a full rebuild. Verify export fidelity before scoping anything. Platform is active and EU-hosted. Typical migration: 8–12 weeks, $13K–$25K.

## Platform status

- Status: active — Betty Blocks launched 'Betty Blocks Open' (2024–2025) and 'Betty Genius' AI; a technical webinar on the new architecture ran Feb 19, 2026. The platform now claims apps export as standard React (frontend) + WebAssembly (backend) that runs on any infrastructure. This claim is vendor-sourced and has not been independently verified as of July 2026. Pre-2025 apps were on a proprietary runtime with no code export.
- Migration urgency: low
- Typical timeline: 8–12 weeks
- Typical cost: $13K–$25K (agency, fixed)

## Why migrate

Betty Blocks is in genuine architectural transition. The migration case differs sharply depending on when your app was built — the pre-2025 and post-2025 architectures are effectively different products.

- **Unverified export claims for a historically locked platform** — Betty Blocks' React + WebAssembly export is a new (2025–2026) vendor claim. Pre-2025 apps had no code export (noted in historical G2 reviews). Verify independently before planning a migration around the export claim.
- **Enterprise pricing without flexibility** — Betty Blocks targets enterprise and citizen-developer segments with corresponding pricing. If the use case has scaled beyond its original scope, the per-seat cost may no longer be justified relative to a custom-code alternative.
- **Legacy apps built before 'Betty Blocks Open'** — Apps built on Betty Blocks' pre-2025 architecture may not benefit from the new export capabilities. This creates a two-tier situation within the same vendor — clients need to confirm which architecture their app is on.
- **Back-office complexity ceiling** — Betty Blocks excels at case management and approval workflows but hits limits for complex frontend customisation. Teams building beyond those patterns run into the proprietary-UI constraint regardless of which architecture they are on.
- **WebAssembly skill requirement post-export** — The exported WebAssembly backend supports Rust, TypeScript, Python, and .NET. If the team is not skilled in any of these, extending the exported backend post-migration requires a rewrite — a cost that must be scoped upfront.

## What you can export

Export feasibility depends entirely on app architecture version. Post-2025 'Betty Blocks Open' apps may export as React + WebAssembly — but this is vendor-claimed, not independently verified. Pre-2025 apps: no code export, data access via support, treat as a full rebuild.

| Asset | Exportable | How |
| --- | --- | --- |
| Data | partial | EU private cloud and on-prem deployments give direct DB access; cloud-only deployments require support engagement for data export |
| Code | partial | New 'Betty Blocks Open' (2025–2026) claims apps export as React (frontend) + WebAssembly (backend) running on any infrastructure; supports Rust/TypeScript/Python/.NET |
| Design/UI | partial | New architecture uses React 19; UI components may be exportable with the code export |
| Logic/Workflows | partial | WebAssembly backend logic claimed exportable per Betty Blocks' 2025–2026 documentation; verify independently |
| Users & Auth | partial | On-prem and EU cloud deployments may have direct DB access for user records |

## Stack mapping

Target stack is Next.js + Supabase (PostgreSQL). Post-2025 exports may provide React components to extend or port; pre-2025 apps require a full rebuild using the Betty Blocks model as specification.

| Platform concept | Code equivalent |
| --- | --- |
| Betty Blocks model (data entities) | Supabase PostgreSQL tables |
| Betty Blocks UI (pre-2025, visual) | Next.js pages + React components (rebuild) |
| Betty Blocks Action / Function | Next.js Server Action or API Route Handler |
| Betty Blocks Role / Permission | Supabase Row-Level Security policies |
| Betty Blocks workflow (case management) | Custom state machine in PostgreSQL + Next.js Server Actions, or n8n for orchestration |
| Betty Blocks forms | react-hook-form + zod on Next.js pages |
| Betty Blocks SSO/SAML | Supabase Auth SAML provider or Clerk for enterprise SSO |
| Betty Blocks scheduled jobs | Supabase pg_cron or Vercel Cron Jobs |

## Migration roadmap

The first step is determining which Betty Blocks architecture the app is on — this splits the migration into two fundamentally different projects. Do not skip the verification step.

### Phase 1: Architecture verification and export proof (Week 1–2)

- Confirm whether the client's app is on pre-2025 or post-2025 ('Betty Blocks Open') architecture
- Request a proof-of-export from Betty Blocks: export a test module and verify the React + WebAssembly output is independently runnable
- Get the export capability confirmed in writing from Betty Blocks before scoping the migration
- Export all data from the platform — coordinate with Betty Blocks support for cloud deployments
- Confirm data-residency and GDPR compliance requirements before initiating any data transfer

> Watch out: Do not scope or price the migration until the export proof is in hand — an unverified claim that fails changes the entire project from a port to a full rebuild

### Phase 2: Documentation and specification (Weeks 2–3)

- Document all workflows, roles, and permission structures via the Betty Blocks admin console
- Screenshot all UI screens to build the rebuild specification (essential for pre-2025 apps)
- Map every approval chain, SLA rule, and escalation trigger in the case management workflows
- Get a contractual data-export commitment from Betty Blocks before starting migration work

### Phase 3: Foundation and data migration (Weeks 3–5)

- Set up Next.js + Supabase project; configure CI/CD pipeline
- Design PostgreSQL schema from Betty Blocks data model; run migration and validate record counts
- Implement Supabase Row-Level Security policies mapped from Betty Blocks roles
- Configure SSO/SAML in the new identity provider; validate login flows

### Phase 4: Application rebuild or port (Weeks 4–10)

- Post-2025 export path: integrate exported React components into Next.js; port or rewrite WebAssembly backend logic
- Pre-2025 rebuild path: build Next.js pages and Server Actions from the screenshot specification
- Re-implement case management state machines in PostgreSQL + Server Actions; test every SLA escalation path
- Build forms with react-hook-form + zod; map all validation rules from the Betty Blocks form editor

> Watch out: Case management in-flight items need a case-freeze window or parallel-run period — do not cut over while active approval chains are unresolved

### Phase 5: UAT and cutover (Weeks 10–12)

- Run UAT with process owners; verify every workflow stage and escalation path
- Plan case-freeze window for active in-flight work items
- DNS cutover to new Next.js deployment on Vercel
- Cancel Betty Blocks subscription after confirming the new system is stable

## Cost paths

| Path | Cost | Timeline | Fits |
| --- | --- | --- | --- |
| DIY (self-directed with AI tools) | $0–$500 + your time | 4–8 months part-time | Teams who have confirmed post-2025 export works and have in-house React/TypeScript developers who can extend the exported components |
| Freelancer | $4K–$12K | 2–4 months | Simpler back-office apps with a confirmed post-2025 export and limited case management complexity |
| Agency (RapidDev) | $13K–$25K fixed | 8–12 weeks | Teams on either architecture who want a verified, fully-owned Next.js + Supabase codebase — we handle the export proof, GDPR compliance, and case management rebuild |

## Risks and mitigations

- **Unverified export claim** — Request a proof-of-export in a test environment before contract sign-off. If the React + WebAssembly export does not work as advertised, the migration is a full rebuild — a different scope and budget.
- **Pre-2025 legacy architecture with no export** — Confirm app build date and architecture version with Betty Blocks before scoping. Apps built before 'Betty Blocks Open' (2025) are on a proprietary runtime with no code export.
- **WebAssembly skill requirement** — Exported WebAssembly backend may require Rust or TypeScript skills to extend post-migration. Assess team capabilities and budget a TypeScript rewrite of the backend if Rust/WASM is not in the team's wheelhouse.
- **Case management state loss during cutover** — Complex approval chains may have in-flight cases during migration. Plan a case-freeze window or parallel-run period for active workflows; migrate active items manually or export via API before cutover.
- **EU data residency and GDPR** — If using EU private cloud, data export must comply with GDPR. Confirm data transfer mechanisms and data-processing agreements before extracting any data from the platform.
- **Pricing change or data-export refusal during migration** — Betty Blocks pricing is enterprise and sales-gated. Get a contractual data-export guarantee in writing before beginning migration work — this protects the timeline if the vendor relationship changes.

## Stay or go

Stay if:

- Your organisation is building citizen-developer apps across multiple departments and Betty Blocks' governance model — role-based builders, environment management — is actively used by non-technical teams
- You are in the EU, need EU data hosting, and Betty Blocks' private cloud satisfies your data-residency requirements without additional infrastructure overhead
- The 'Betty Blocks Open' React/WebAssembly export has been independently verified to deliver clean, maintainable code — in which case lock-in is no longer the concern

Go if:

- Your app was built on pre-2025 Betty Blocks architecture and the export claim does not apply — you are in a full-rebuild situation that is better done now than after more development investment
- Your case management needs have outgrown Betty Blocks' workflow model and you are building workarounds rather than features
- Your development team wants to hire mainstream JavaScript/TypeScript developers and the Betty Blocks skill requirement is becoming a hiring constraint

Betty Blocks is in genuine transition — the React/WebAssembly export claim is significant if true. Verify it before building a migration plan around it. Pre-2025 apps are in the standard enterprise lock-in situation, and the migration decision should be made on that basis.

## Migration checklist

- Confirm whether the client's app is on pre-2025 or post-2025 ('Betty Blocks Open') architecture — These are effectively different products with different export capabilities — the architecture version determines whether this is a port or a full rebuild
- Request a proof-of-export from Betty Blocks before scoping the migration — Export a test module and verify the React + WebAssembly output is independently runnable; get this confirmed in writing before any contract is signed
- Export all data from the platform and confirm record counts — Data is the only fully portable asset; coordinate with Betty Blocks support for cloud deployments and confirm counts before closing the account
- Document all workflows, roles, and permission structures via the admin console — Case management approval chains encode business rules that often exist nowhere else; document every stage, condition, SLA rule, and escalation trigger
- Screenshot all UI screens to build the rebuild specification — Essential for pre-2025 apps where no UI export exists; screenshots become the frontend specification
- Confirm data-residency and GDPR compliance requirements before initiating any data transfer — EU private cloud data must comply with GDPR; confirm data transfer mechanisms and DPAs before extracting
- Get a contractual data-export commitment from Betty Blocks before starting migration work — Protects the migration timeline if pricing, support, or the vendor relationship changes mid-project

## Frequently asked questions

### Can I export my Betty Blocks app code?

It depends on when your app was built. Apps on the post-2025 'Betty Blocks Open' architecture may export as React (frontend) + WebAssembly (backend) per Betty Blocks' vendor documentation — but this has not been independently verified as of July 2026. Apps built on the pre-2025 architecture had no code export per historical G2 reviews. Request a proof-of-export from Betty Blocks before making any migration decisions.

### How long does a Betty Blocks migration take?

8–12 weeks for a typical app when working with an agency. If the post-2025 export works as claimed, the timeline is closer to 8 weeks (port rather than rebuild). A pre-2025 full rebuild with complex case management workflows is more likely to take 12–16 weeks. The GDPR data-export coordination for EU cloud deployments adds 1–2 weeks to any timeline.

### What happens to my users and passwords after migration?

Betty Blocks uses SSO/SAML for enterprise authentication, meaning user accounts are typically in an external identity provider (IdP) that you control. Migrating SSO configuration to Supabase Auth or Clerk is a well-defined process. Password hashes are not documented as exportable. If Betty Blocks built-in auth is used, plan a forced password reset for users at cutover.

### Is Betty Blocks shutting down?

No. Betty Blocks is actively developing — 'Betty Blocks Open' and 'Betty Genius' AI launched in 2024–2025, with a technical architecture webinar in February 2026. The platform is stable and EU-hosted. Migration urgency is driven by use-case ceiling (case management complexity, frontend customisation limits) and the pre-2025 lock-in situation, not platform risk.

### Does the Betty Blocks WebAssembly export actually work?

This is the most important question to answer before scoping any migration. Betty Blocks claims apps built on the 2025+ architecture export as React + WebAssembly that runs on any infrastructure. As of July 2026, this has not been independently verified. Request a proof-of-export — export a real module from your app and confirm it runs outside the Betty Blocks platform — before building a migration plan or signing a contract.

### What is the migration target stack from Betty Blocks?

Next.js (App Router) + Supabase (PostgreSQL + Auth + Row-Level Security). Case management workflows become custom state machines in PostgreSQL with Next.js Server Actions. Betty Blocks roles become RLS policies. For apps with confirmed post-2025 export, the exported React components can be extended or ported directly into the Next.js structure.

### How does RapidDev handle Betty Blocks migrations?

RapidDev offers a free scoping call that includes verifying the architecture version, requesting a proof-of-export, and confirming GDPR data-transfer requirements. From there, we scope to a fixed price: $13K–$25K, 8–12 weeks. Whether the migration is a post-2025 port or a pre-2025 rebuild, the output is a fully-owned Next.js + Supabase codebase with no Betty Blocks dependency.

### How do I handle in-flight approval workflows during the migration?

Active case management workflows (approval chains with in-flight items) need a dedicated cutover strategy. Options: a case-freeze window where no new items enter the old system for 24–48 hours; a parallel-run period where both systems are active; or manual migration of in-flight items via API export before cutover. The right approach depends on volume — plan this explicitly in the migration scope.
