Small changes depend on hidden product knowledge
Fixes and workflow edits keep waiting on whoever remembers roles, plugins, edge cases, old workarounds, and how the app is really wired.
Live Bubble App Migration
Bubble got your product live. Improving it shouldn't be this slow, expensive, or risky.
AppRebase moves your live Bubble app into code when new features, fixes, and improvements have become too slow, expensive, or risky to keep shipping inside Bubble.
Your Bubble app still works. Improving it shouldn't be this slow.
When feature work, fixes, integrations, and admin changes keep taking more specialist time, Bubble stops feeling like startup speed and starts taxing every next move.
New requirements fight the old setup
Integrations, reporting, admin tools, mobile flows, and reliability work take more cleanup and coordination than they should.
Modern teams now move from a faster baseline
Code-based teams can use tests, review, AI agents, and parallel tasks while your roadmap stays tied to manual Bubble-specific work.
Rebuild what the business depends on, not every Bubble workaround.
AppRebase maps what the app really does for users, admins, data, integrations, and mobile flows. Then the approved behavior is rebuilt in the right web stack, or as a native or Flutter app when mobile is part of the product, while obsolete fields, dead workflows, and old workarounds can be redesigned or left behind.
Keep true
Must stay true in the new app
- Key web screens, mobile flows, and customer/admin workflows
- Roles, permissions, business data, files, payments, integrations, and reports
Do not clone
Can be redesigned or left behind
- Old Bubble workflows, plugin workarounds, brittle schema, and accidental complexity
- Dormant fields, unused features, and dead workflows that no longer serve the product
Controlled migration path
Start with a fit call. Audit before quoting. Migrate only the agreed work.
No blind rebuild, no quote from screenshots, and no implementation commitment until the next step is approved.
01Fit call
See whether moving from Bubble makes sense
A 20-minute low-access call checks product stage, roadmap pressure, live operations, and obvious no-go risks. No Bubble access, export, or secrets needed.
Decision Not a fit, continue to a scoping audit, or clarify what needs checking first.
02Audit
Turn the live app into a migration scope
If there is a fit, the scoping audit uses agreed Bubble editor access, the Bubble export file, and founder context to define what gets rebuilt, excluded, reshaped, and protected.
Decision Fixed scope, quote, timeline, assumptions, and exclusions.
03Migration
Build the agreed migration
After quote approval, AppRebase rebuilds the agreed behavior in code with migrated data, validation, docs, and handover inside scope.
Result An inspectable codebase ready for future changes.
Migration Scope Audit
Get a fixed-scope migration quote without gambling on screenshots.
A quick call can give a rough range. It cannot produce a fixed-scope quote AppRebase should stand behind. After a fit call, AppRebase reviews the real app through read-only Bubble editor access, the Bubble export file, custom AI-assisted export analysis, manual review, and founder context so we can agree the migration scope, fixed price, and timeline before development starts.
Shared output
Agreed migration scope, fixed price, and timeline.
AI-assisted export analysis helps surface workflows, data structures, plugins, and dependencies. Together we decide what existing behavior is in scope, what can be left out, and what should wait for a later phase.
Rebuild now
Key screens, workflows, data, roles, integrations, and reports from the current app.
Leave out
Dormant features, obsolete fields, unused workflows, and old Bubble workarounds.
Handle later
New features, deeper redesign, or product expansion that should become a separate phase.
Quote and timeline
Fixed price, expected timing, assumptions, exclusions, and the limits of the migration.
The audit does not hand over an architecture pack, build specification, detailed implementation plan, or wireframes. It defines the shared scope and gives you the fixed price and timeline. If budget, timing, or scope do not fit, you can stop there.
When migration makes sense
For Bubble apps that still matter enough to improve.
AppRebase is strongest when your Bubble app already runs real work, but every next feature, fix, integration, or admin improvement is slower, costlier, or riskier than it should be.
The app is useful, active, and starting to drag.
- Customers, internal teams, revenue, workflows, or admin screens depend on it.
- You still need meaningful product changes: features, fixes, integrations, reporting, admin tools, or mobile improvements.
- Your Bubble product includes a wrapped mobile app that now needs a real native or Flutter build.
- You want the useful product behavior rebuilt in code, not a cheap clone of old Bubble workarounds.
Founder-led migration judgment
Scoped by a Bubble-native builder, not handed to a generic dev team.
Sergii reviews the app, the audit findings, and the migration scope himself, so the quote is based on what the product really does and what should not be blindly copied.

What people say about Sergii.
I have worked with Sergii for multiple projects over the last 3 years. The latest was a migration of complex communications tool from bubble.io to native mobile Flutter/FastAPI, which we've just deployed!
He is skilled, has high work ethics and someone to trust. If you consider working with him just reach out and I'm happy to endorse.
Over the last 3 years I've been working together with Sergii on various projects from first idea, a set of wireframes, MVP up to a fully functioning product with thousands of users enjoying it.
He's not just a developer with great skills, but a trusted partner who can make a lasting impact on your business.
Before booking
Questions before booking a fit call.
Short answers about access, the audit, scope, and migration risk.
Do I need to share access before the first call?
No. The first call is low-access. No Bubble export, admin or editor access, credentials, secrets, or production customer data are needed for the first conversation.
What access is needed for the scoping audit?
After a fit call, AppRebase needs agreed Bubble editor access, with read-only access acceptable where possible, and the Bubble export file. Access is requested only after audit scope, handling rules, AI-assisted analysis disclosure, and consent are clear.
Why do you audit before giving a fixed quote?
A live Bubble app cannot be priced precisely enough for a fixed-scope quote and timeline from screenshots or a quick call. The audit combines custom AI tooling, export analysis, manual app review, and founder context to agree what is in scope, what is excluded, what should wait, and what the migration will cost.
What do I receive after the audit?
The client-facing output is the agreed migration scope, fixed price, and timeline. AppRebase may create internal architecture notes, build specifications, or implementation plans for delivery, but those are not audit handover documents unless a later paid agreement explicitly includes them.
Does the audit obligate me to continue?
No. The audit is required before AppRebase can prepare a responsible migration quote, but it does not obligate you to approve implementation. If the budget, timing, scope, or handling rules do not fit, you can stop there.
Will you rebuild everything exactly as it exists in Bubble?
No. The goal is to rebuild the product behavior, screens, data, and workflows users rely on. Old Bubble clutter, obsolete fields, unused features, and accidental workarounds do not need to be copied.
Can you rebuild wrapped Bubble mobile apps?
Yes, if mobile is part of the agreed scope. AppRebase can rebuild the mobile experience as a native or Flutter app instead of preserving a wrapped Bubble app. The exact web or mobile stack is chosen during scoping based on the product, roadmap, budget, and handover needs.
Can you guarantee zero downtime or no data loss?
Not before the app is understood. The responsible commitment is to identify continuity, data, auth, workflow, validation, and cutover risks before implementation, then scope the migration around what has to stay safe.
Migration fit call
Book a 20-minute Bubble migration fit call.
Tell us what your Bubble app does, what changes are getting slow, and what workflows you cannot break. If migration looks worth scoping, the next step is an export-based audit to agree scope, fixed price, and timeline.
No Bubble export, admin or editor access, credentials, secrets, or production customer data needed for the first call.
