Founders past validation
The idea is proven and the platform is now the ceiling. You want a codebase that can carry the next stage of growth.
Migrate Bubble → custom code
Rebuild and improve your Bubble app as custom code.
Bubble got the idea into production. When performance, cost, hiring, or a diligence question makes the platform the constraint, we rebuild the app as maintainable custom code — one bounded piece at a time, with the live app running until you choose to cut over.
See fixed-price packages, walk through how the process works, or read the Bubble-to-Next.js path in detail.
Who it’s for
Teams that have outgrown the platform, not the idea.
Engineering leaders
You will own the result and need something a senior hire can read, extend, and put through a security review.
Operators with a diligence deadline
An acquirer, investor, or enterprise buyer has asked for something Bubble's shared platform can't attest to on its own.
When to stay on Bubble
A rebuild you don’t need is the most expensive kind.
- You are still finding product-market fit and the requirements change weekly.
- The app is low-traffic and internal, where Bubble's speed of change is worth more than performance.
- Nothing about cost, compliance, hiring, or performance is currently blocking the business.
When a rebuild pays for itself
The platform is now the thing holding the business back.
- Per-seat or workload-unit cost scales faster than revenue.
- You need to hire engineers, and the talent market is on code.
- Performance, SEO, or a security review has become a hard requirement.
- You want a codebase you fully own and can extend without platform limits.
How the rebuild works
Every migration follows the same disciplined path.
Assess before we scope, rebuild in bounded stages, validate against the live app, and cut over on your schedule. Each stage below is a concrete piece of work with an owner and an exit condition.
Stage 01
Assess
App inventory
We catalog every page, data type, workflow, plugin, and API connector in the current app, and score each for how hot the path is. The output is a shared map of exactly what exists — the basis for what moves, what stays, and in what order.
Stage 02
Assess
Workflow and data mapping
Bubble workflows and data types are translated into an explicit domain model: entities, relationships, and the business rules each workflow encodes. Privacy rules that survive translation are documented, and original record identifiers are preserved so data can be reconciled during cutover.
Stage 03
Design
Target architecture
We propose a maintainable, hire-able stack — a typed application layer, a relational database with schema-first migrations, durable background jobs, and portable hosting. Nothing exotic and nothing locked to us; the goal is a codebase a new engineer can ship in within a week.
Stage 04
Design
Plugins and integrations
Each Bubble plugin and connector is mapped to a maintained library, a direct API integration, or a small amount of custom code. Where there is no clean equivalent, we surface the trade-off during the inventory rather than discovering it mid-build.
Stage 05
Build
Staged rebuild
The spine — the handful of workflows that actually move the business — is rebuilt first, each as its own reviewable change. The long tail of pages is batched by similarity so related screens ship together. The live Bubble app keeps running throughout.
Stage 06
Prove
Validation and cutover
We validate the rebuild against the live app — workflow behavior, data parity, and the paths that carry revenue — before any traffic moves. Cutover is a planned, monitored window with a documented rollback, run on a schedule you control rather than a big-bang switch.
Clean handover
Take the keys and run it yourself.
You get the repository, infrastructure, environment configuration, and documentation — everything an engineer needs to own the system. If you have an in-house team, they take it from cutover.
Ongoing development
Or keep building with us.
If you would rather keep shipping features without hiring immediately, we can continue as your development team on the new codebase. Either way the code is yours and the choice stays open.

Frequently asked
Questions teams ask before a Bubble rebuild.
Concrete answers on parity, ownership, plugins, and cutover. If something here doesn't match your situation, raise it on the review call.
- Does my Bubble app keep running during the migration?
- Yes. The Bubble app stays live and is the source of truth until you decide to cut over. We rebuild the spine on code alongside it, validate parity, and only then move traffic — so there is no stop-the-world window.
- Do you need write access to my Bubble app?
- No. We work from a read-only export and, where useful, read access to inspect workflows and data types. We do not write to your Bubble app during the rebuild.
- What happens to my Bubble plugins and integrations?
- We inventory every plugin and API connector, then map each to a maintained library, a direct API integration, or a small amount of custom code. Where a plugin has no clean equivalent, we flag it during the inventory so the trade-off is a decision you make, not a surprise.
- Can I keep some things on Bubble?
- Often that is the right call. Internal admin tools and low-traffic screens can stay on Bubble while the customer-facing spine moves to code. We score which pages belong on which side during the app inventory.
- Who owns the code?
- You do, from the first commit. We push to your GitHub organization as collaborators and hand over infrastructure, environment configuration, and documentation at the end. Nothing is locked to us.
- How do you handle user passwords?
- Bubble does not export password hashes, so we use a migration path such as one-time passcodes or magic links. Existing users re-establish credentials on first login, or stay signed in via a session bridge, rather than being silently reset.
