What is Bubble.io Migration?
Bubble.io migration is the process of rebuilding a Bubble.io application on a custom code stack — Next.js, Rails, Django, or similar — to overcome platform limitations in performance, compliance, or scalability.
Why Migrate?
Bubble.io is an excellent prototyping platform, but growing applications hit hard ceilings. Performance degrades as data volumes increase, Workload Unit costs scale faster than revenue, and enterprise compliance requirements — SOC 2, HIPAA, GDPR — are difficult or impossible to satisfy within the platform's constraints.
Migration Approaches
Big Bang
Rebuild the entire application at once, then cut over. High risk, faster completion for smaller apps.
Strangler Fig
Gradually replace Bubble features with custom code, routing traffic incrementally until Bubble is retired.
Hybrid Architecture
Keep Bubble for non-critical workflows while migrating core data and APIs to a custom backend.
Data-First
Migrate the database and APIs first, then rebuild the frontend against the new backend layer.
Key Challenges
- Hidden Backend Logic — Bubble workflows encode business rules visually — they must be read and translated manually without proper tooling
- Data Migration — Bubble uses a flat, proprietary data structure that must be mapped to relational or document schemas
- Feature Parity — Bubble plugins provide functionality that requires custom implementation in code — each plugin is a hidden dependency
- Privacy Rules — Bubble privacy rules act as row-level security and must be replicated in the new stack's authorization layer

How Relis Accelerates Migration
Relis extracts your entire Bubble architecture — data types, workflows, API connectors, and privacy rules — into developer-ready documentation before you write a single line of migration code. Teams that use Relis cut discovery time from weeks to under 10 minutes.
