We move live apps off platforms that don't make leaving easy.
Bubble to React and Supabase. Lovable Cloud to your own Supabase. Base44 or Replit to code you own. Live apps, every login intact, and every key handed to you at the end.
- A 5,000-student school platform moved with zero downtime
- fixed price after the audit
Migrations we run.
- Lovable Cloud to your own Supabase
- The one everyone says is impossible because Lovable hides your database credentials. Schema, policies, storage, auth users and sessions all come across. Done live, on a school platform with 5,000 students.
- Bubble to React and Supabase
- When workload units, page speed or an investor's due-diligence list make Bubble the wrong home. Same product, modern stack, pages that load instantly.
- Base44, Replit or Bolt to code you own
- Great for the prototype, shaky under real users. The 80% the AI built becomes a real codebase on Next.js and Postgres, deployed on your accounts.
- A previous developer's codebase to something maintainable
- Audited, untangled and moved to a stack the next developer can pick up in a day, with the data intact.
Sound familiar?
- Your app lives on Lovable Cloud and you can't get your data outLovable Cloud to Supabase
- Bubble's limits have become your product's limitsBubble to React
- You want your own Supabase and you're afraid of downtimeHow it runs
- The platform says leaving isn't possibleIt is
- An investor or acquirer asked who owns the code and the dataMigrations
How a migration runs
- 1
Audit and map
We inventory everything: schema, policies, files, users, integrations. You get a fixed price and a timeline.
- 2
Build the new home
The new infrastructure goes up in parallel. Your live app keeps running; users notice nothing.
- 3
Migrate and verify
Data, files and users move with row counts and checksums verified on both sides. Sessions and passwords survive; nobody gets a reset-password email.
- 4
Cut over, zero downtime
Traffic switches when everything is proven. We watch it live, keep the old platform read-only for 30 days, and hand you every key.
What it costs
from $3,500
fixed after the audit, 2 to 8 weeks
Small apps take two weeks; large ones with files, payments and many roles take six to eight. The audit gives you the exact number before you commit, and the old platform stays read-only for 30 days after cutover.
- Full inventory and a written migration plan
- Data, files, auth users and sessions moved and verified
- Zero downtime cutover
- Every account and key in your name
Straight talk, shipped on time, no surprises.
Fast, reliable, and actually understands Bubble at a deep level.
“JetBuild delivered exactly what we scoped, on time, with zero hand-holding needed. They understand Bubble at a production level, not just getting things to work, but building them properly.”
Brian Luerssen, Founder at DraftBit
Built our entire booking system and payment flow from scratch.
“We needed a booking platform with Stripe payouts and role-based dashboards. JetBuild scoped it clearly, built it fast, and it worked on day one. No back and forth, no surprises.”
Marcus Webb, Co-Founder at GreenRoute Logistics

You own everything
Code, data, accounts and infrastructure are yours at the end.
Questions founders ask first
No. Auth users, hashed passwords and active sessions move with the data. On the school platform every one of 5,000 students opened the app the next morning as if nothing had happened.
It isn't. The new stack is built alongside the old one, migrated in a dry run, verified, and then traffic is switched. Zero downtime is the plan, not the hope.
Yes. It's the migration we're known for. The write-up, with 1,800 tables and 6,000 security policies, is on the blog.
Migrate if the data model is sound and the product works; rebuild if it doesn't. The audit is where that call gets made, in writing, before any money changes hands.
