Migration snapshot
ActivePlatform
a Betty Blocks
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.

Why teams leave a Betty Blocks
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 can you actually take with you?
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 | Can you export it? | How | Notes |
|---|---|---|---|
| Data | Partial | EU private cloud and on-prem deployments give direct DB access; cloud-only deployments require support engagement for data export | Specific export mechanism not documented in primary sources as of July 2026; coordinate with Betty Blocks support before starting migration |
| 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 | Pre-2025 apps: proprietary runtime, no code export (per historical G2 reviews) — treat as a rebuild; verify current export fidelity before scoping a migration |
| Design/UI | Partial | New architecture uses React 19; UI components may be exportable with the code export | Pre-2025 design and UI: proprietary, not exportable; screenshot inventory is the practical method for legacy apps |
| Logic/Workflows | Partial | WebAssembly backend logic claimed exportable per Betty Blocks' 2025–2026 documentation; verify independently | Business logic in pre-2025 apps is not exportable without a rebuild; case management workflows must be re-documented from the admin console |
| Users & Auth | Partial | On-prem and EU cloud deployments may have direct DB access for user records | Password hashes not documented as exportable; SSO/SAML users may need re-enrolment in the new identity provider |

Where each piece moves in code
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.

The 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.
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
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
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
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
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
Three ways to migrate — honestly
Every path has a real trade-off. Here is what each costs, how long it takes, and where it bites.
DIY (self-directed with AI tools)
$0–$500 + your time
4–8 months part-time
Fits
Teams who have confirmed post-2025 export works and have in-house React/TypeScript developers who can extend the exported components
Risks
WebAssembly backend may require Rust skills to extend; case management state machines are complex to build correctly without backend experience; unverified export may fail mid-project
Freelancer
$4K–$12K
2–4 months
Fits
Simpler back-office apps with a confirmed post-2025 export and limited case management complexity
Risks
Freelancers may not have experience with Betty Blocks' architecture or WebAssembly backends; GDPR data-transfer compliance adds complexity for EU deployments
Agency (RapidDev)
Done-for-you$13K–$25K fixed
8–12 weeks
Fits
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
Minimal — fixed price, defined scope, free scoping call to assess architecture version and export feasibility before contract
The real risks — and how to defuse them
Unverified export claim
Mitigation: 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
Mitigation: 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
Mitigation: 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
Mitigation: 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
Mitigation: 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
Mitigation: 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.
Should you actually migrate?
Migrating is a real project. Sometimes staying is the right call — here is the honest split.
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
Migrate 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
Our honest verdict
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.
Do this today: pre-migration checklist
Whatever path you choose, protect yourself first. Work through this before you touch a line of code.
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.
