How to migrate a Bubble.io app to Next.js
Your Bubble app got you here. A real codebase gets you to the next build.
A Bubble.io to Next.js migration means rebuilding the app as a codebase you own while the Bubble app stays live, then switching the domain when the new app is verified. I map every workflow and data type first, build in Next.js and TypeScript, move the records and users, and cut over once it matches.

Three things
migration delivers
Protect what you've built
Every workflow, page, and piece of data migrated faithfully. The app keeps running. Customers don't notice. You don't lose what made Bubble worth choosing in the first place.
Future-proof the foundation
A real codebase. Owned by you. Hireable on any platform. Hostable anywhere. No more compounding WU bills, abandoned plugins, or editor lock-in. Built to grow with you for the next ten years.
Unlock AI-powered development
Bubble apps are invisible to AI coding agents. Once you're on real code, every AI tool — Cursor, Claude Code, Codex — can read your codebase, ship features alongside you, and 10x your velocity. Migration isn't just an escape. It's the door to building with AI.
What you keep.
What you gain.
Your data, every record
A codebase you own outright
Every workflow & business rule
Real engineering practices — version control, code review, automated tests
Your users & their accounts
Hireable on any modern platform
Your domain & live app
Predictable infra cost, no per-WU compounding
Your roadmap
AI agents can read, write, and ship features in your code
How it works
Audit & Blueprint
I map every workflow, plugin, and data model in your Bubble app and produce a migration blueprint with timeline and cost. Nothing starts until you've approved the plan.
Parallel Build
Your Bubble app stays live. I rebuild on a modern codebase in parallel, milestone by milestone. Existing users experience zero disruption.
Data Migration
Your records, users, and history move over with full integrity. The migration is verified end-to-end before any cutover occurs.
Cutover
Domain switches to the new app. Bubble stays available read-only as a safety net during the transition period.
Handoff
You get a documented, AI-ready codebase. Bring on any developer or use AI coding agents — you're no longer dependent on me, Bubble, or anyone.
Why me
“Most Bubble migration consultants are either Bubble agencies that don't really code, or coders who've never touched Bubble and underestimate it. I'm the rare third thing.”
Deep Bubble.io fluency — built inside the platform, not around it — combined with production-grade coding experience across SaaS, AI, and marketing products.
I know what your Bubble app actually does, what your workflows mean, and what the editor hides. That's why migrations I lead don't lose features — they reveal them.
Built on a modern, hireable stack — Next.js, Postgres, TypeScript, and best-in-class tooling. Full stack details on request.
Common Questions
How do I migrate a Bubble.io app to Next.js without downtime?
The Bubble app stays live. I build the Next.js app in parallel, move data only after it is checked, then switch the domain.
What do I actually get after migration?
A Next.js and TypeScript codebase you own, your records and users moved, and a handoff another developer or an AI coding tool can work on.
Will I lose Bubble workflows or data?
No. The audit maps every workflow and data type before I write the new app. Cutover happens after that is verified.
Why can’t Cursor or Claude Code edit a Bubble app?
Bubble has no codebase those tools can read. After the move they can.
Do you work with Ontario and US founders on this?

Ready to migrate?
The first step is a conversation. Tell me about your Bubble app — what it does, where you've hit limits, and where you want to go. I'll come back with an honest assessment and a clear path forward.
