How do I migrate off Bubble to Next.js + Postgres without losing users?
How do I migrate off Bubble to Next.js + Postgres without losing users?
The Bubble-to-Next.js migration runs in four phases over 4–8 weeks: scope (inventory data types, workflows, plugins, and integrations), export (pull all data via CSV + Data API, screenshot every screen, document every workflow), rebuild (Next.js 16 App Router + Postgres + Clerk or Auth.js + Stripe, structured as a git repo you own), and cutover(run Bubble and Next.js in parallel for 1–2 weeks, swap DNS in a maintenance window under 10 minutes, keep Bubble as rollback for 30 days). Users re-authenticate once; URLs, data, and Stripe subscriptions all survive. Typical cost: $15k–$40k fixed-price.
Quick fix for How do I migrate off Bubble
Phase 1 — Scope and diagnostic (Week 1)
Inventory every data type, every workflow, every installed plugin, and every API Connector integration. Document the critical user journeys (signup, checkout, the top 3 product actions). Decide what ships in v1 of the rebuild and what can wait. A common mistake is rebuilding 100% of what’s in Bubble — often 15–30% of Bubble features are vestigial and don’t need to carry forward.
Deliverable: a migration scope document, a revised URL map, a Stripe compatibility plan, and a rollback plan.

Phase 2 — Data export and schema design (Week 1–2)
Export every data type from Bubble as CSV. For anything too large for CSV, use the Bubble Data API to pull paginated JSON. Design the Postgres schema — this is the only step where you get to clean up data type inconsistencies the Bubble app accumulated. Write a seed script that loads the CSV/JSON into Postgres idempotently, so you can re-run it as the Bubble app continues to accumulate data during the rebuild.

Phase 3 — Rebuild in Next.js + Postgres (Week 2–6)
Next.js 16 App Router scaffold. Postgres (managed on Supabase, Neon, or RDS) with Drizzle ORM for type-safe queries. Clerk or Auth.js for identity. Stripe via the official Node SDK. Tailwind + shadcn/ui for UI components. Deploy to Vercel for the frontend; workers on Fly or Railway if you need them. Rebuild screen by screen, workflow by workflow, starting with signup and checkout and ending with the less-critical admin surfaces.
At the end of Phase 3, the new app is functionally complete and fed by a scheduled data sync from Bubble (runs every 15 minutes; keeps the two apps data-compatible).
- 04
Phase 4 — Parallel run and cutover (Week 6–8)
Run both apps in parallel for 1–2 weeks against real traffic (Next.js is available at a staging subdomain; Bubble handles production). Internal team tests every workflow end-to-end. When ready: schedule a maintenance window (typically 2am user-local-time on a Tuesday), drain Bubble by switching it to read-only, run the final data sync, swap DNS CNAME to point the production domain at Next.js, send users a one-time password-reset email, and monitor for 2 hours before declaring success.
Keep Bubble live (but read-only) for 30 days as a rollback path. Revoke after 30 days if no issues.

Phase 5 — Post-cutover monitoring and handoff
For 2 weeks after cutover, monitor the Next.js app for performance regressions, Stripe webhook delivery failures, SEO crawl errors, and any customer support tickets mentioning anomalies. Hand off the repo to the client’s engineer (or retain us for ongoing support). Revoke the Bubble app after the 30-day rollback window closes.
What we don’t promise
A migration is not a chance to ship major new features. Scope creep is the #1 way migrations go over budget. If the new app has features Bubble didn’t, ship them as a separate release after cutover. The migration’s job is parity plus a better foundation — not parity plus a redesign.

Why AI-built apps hit How do I migrate off Bubble
Founders migrate off Bubble for a predictable set of reasons: enterprise customers need SOC2, code review, or self-hosting; capacity costs outpace what a full Next.js + Postgres stack would cost; a full-time engineer was hired and refused to work in Bubble; or an investor asked about code ownership before a funding round. The platform can be genuinely good up until one of those triggers fires — and once it does, migration is usually cheaper than the alternatives.
The migration is not a line-by-line port of Bubble workflows to Next.js code. Bubble workflows are glue — they wire together database operations, plugin calls, and UI transitions in a platform-specific way that doesn’t have a direct JavaScript equivalent. What migrates cleanly is the data and the intent. You use the Bubble app as the specification and rebuild the implementation natively.
Done well, users don’t notice except that the app gets faster and cheaper. Done poorly, you lose URLs to SEO, log users out, break Stripe subscription state, or ship a rebuild missing 15% of the functionality that only the Bubble app had documented.
“We ran Bubble and Next.js in parallel for two weeks. Cut over at 2am Tuesday. Took 7 minutes. Nobody noticed except our capacity bill dropped to $180.”
Diagnose How do I migrate off Bubble by failure mode
Before the migration starts, scope the app honestly. The table below is the inventory we run on every engagement.
| Migration artifact | How to extract | Where it lands |
|---|---|---|
| Data type schemas | Bubble editor → Data → Types | Postgres + Drizzle schema |
| Data rows | CSV export per type + Data API | Postgres via seed/migrate script |
| User accounts + passwords | Data API for accounts; password reset for auth | Clerk or Auth.js + one-time reset email |
| Workflows | Screenshot + document intent | Next.js server actions or API routes |
| UI pages | Screenshot every screen + note layout | Next.js + shadcn/ui components |
| URLs + SEO | Export URL map from Bubble | Next.js redirects.ts + same-path routes |
| Stripe subscriptions | Already in Stripe — no migration | Point new app at same Stripe account |
| Third-party API keys | Rotate and configure in new env | Next.js .env + secrets manager |
