Migrating From Bubble: The Complete Playbook

A practical guide to rebuilding your Bubble app as custom software — without disrupting your users or losing momentum.

You've decided to move past Bubble. Maybe performance is holding you back, investors want a real tech stack, or you're tired of working around limitations. Whatever the reason, the migration is entirely doable — hundreds of startups have done it successfully.

This guide covers the full process: what to plan, how to prioritize, what the timeline looks like, and how to switch over without losing a single user.

Phase 1: Audit and Document Everything

Before writing any code, we need a complete picture of what your Bubble app does. This sounds obvious, but Bubble apps accumulate features, workarounds, and hidden logic that founders sometimes forget about.

📄

Page Inventory

Every page, popup, and reusable element. Including the ones you forgot exist.

🗄️

Data Model Map

All data types, fields, and relationships. Bubble's data model translates to database schema.

⚙️

Workflow Documentation

Every workflow, API call, and scheduled event. This is where hidden complexity lives.

🔌

Plugin Inventory

Every plugin and what it does. Each needs a native replacement in the custom build.

Phase 2: Prioritize Ruthlessly

Not everything in your Bubble app should be rebuilt. Some features were experiments that didn't work. Some are workarounds for Bubble limitations that won't exist in custom code. The rebuild is an opportunity to cut dead weight.

We categorize every feature as Must Have (core product), Should Have (important but not launch-blocking), or Won't Rebuild (deprecated, unused, or no longer relevant). The first version of the custom app includes only Must Have features.

Phase 3: Choose the Right Tech Stack

The tech stack should match your product's needs, your team's future hiring plans, and your infrastructure requirements.

🌐

Next.js + PostgreSQL

The default choice for most Bubble replacements. Full-stack React with server-side rendering and a real relational database.

🔥

Remix or SvelteKit

Alternatives to Next.js with different trade-offs. Worth considering for specific use cases.

🐍

Django + React

If your team prefers Python or you have complex data processing needs.

📱

React Native

If your Bubble app has a mobile component, this gives you real native apps from a single codebase.

Phase 4: Build in Parallel

Your Bubble app keeps running and serving users throughout the entire rebuild. Users don't know anything is changing. We build the custom version in a separate environment, with weekly demos so you can track progress and provide feedback.

This parallel development approach means zero risk to your existing users and business. If the timeline slips, your Bubble app keeps working. There's no pressure to rush.

Phase 5: Data Migration

Bubble allows CSV export of all data types. We build migration scripts that transform Bubble's data format into your new database schema. This includes handling Bubble-specific quirks like their unique ID format, file references, and geographic data.

For apps with active users, we run the migration in stages: historical data first (during the build), then a final delta migration at switchover time to capture any data created between the initial export and the go-live.

Phase 6: Testing and Switchover

Before going live, we run the custom app through comprehensive testing: automated tests for business logic, manual QA for user flows, and performance testing under load. We also do a "shadow period" where both systems run simultaneously to verify results match.

Switchover is typically a DNS change — your domain points to the new application. We keep the Bubble app available at a subdomain as a fallback for 2-4 weeks, then decommission it.

Common Questions About the Process

What about my Bubble plugins? Every plugin gets replaced with native code. Payment processing becomes Stripe SDK directly. Maps become Google Maps or Mapbox. Charts become D3.js or Chart.js. The native versions are always more performant and reliable than Bubble plugins.

What about my Bubble workflows? Workflows translate to backend API endpoints and frontend event handlers. Complex scheduled workflows become background jobs. The logic is the same — only the implementation changes.

Frequently Asked Questions

How long does a typical Bubble migration take?
Simple apps (10-20 pages, basic CRUD): 6-8 weeks. Medium complexity (20-40 pages, payments, roles): 8-12 weeks. Complex apps (40+ pages, real-time features, marketplace): 12-16 weeks.
Will my users notice the switch?
They'll notice it got faster. The URL stays the same, the core functionality stays the same. We redesign where it makes sense but preserve familiar patterns. Most users don't realize there was a migration — they just notice the app feels snappier.
Can I migrate gradually (one feature at a time)?
It's possible but usually not recommended. Bubble apps are tightly coupled — running half in Bubble and half in custom code creates complex synchronization challenges. A full rebuild is typically faster and cleaner.
What about my Bubble subscription during migration?
Keep it running until the custom app is live and validated. Factor 2-3 months of overlap into your budget. Once you're confident in the new system, cancel Bubble and stop paying.
Do I need to hire developers after the migration?
Not necessarily. We offer ongoing maintenance and feature development. But you have the option — the code is standard React/Node.js that any competent developer can work on.
