Bubble developer, security audits, and migrations off Bubble
Bubble.io is a visual web app builder with a database, workflow engine, and deployment baked in. Powerful, but Workload Units, Privacy Rules, and proprietary runtime become painful at scale.
Top issues we find auditing Bubble apps
Patterns documented in primary-source security research, community forums, and real-world audits. These are the things that ship to production and break in front of users.
Privacy Rules missing or 'Everyone else' allowed
Default state on a new Data Type lets any authenticated user (or anonymous user via the Data API) read all rows. Most scanned Bubble apps have at least one Data Type without rules.
Client-side filtering exposes the unfiltered dataset
When constraints are applied client-side, Bubble downloads all matching records and filters in the browser. DevTools shows the full payload, including fields the page never displays.
Data API key exposed and not rotated
Public Data API often left enabled with no privacy rules.
Sensitive fields in API responses
OTPs, password reset tokens, and hidden user fields leak via the Data API if rules aren't field-scoped.
File Uploader allows arbitrary types
No MIME restriction by default. AWS S3 paths are predictable, so files can be discovered without authentication.
Backend workflows callable as API endpoints
Without 'Run as' checks, backend workflows are publicly invokable.
Workload Unit explosion from inefficient searches
On-page heavy searches re-run on every state change. Reports of $10k+/month bills from apps that scaled past included WU.

Cost & performance gotchas
- Workload Units (WU) are the single biggest cost trap.
- Bulk operations, recursive workflows, and frequent API calls can consume millions of WU in a day.
- Database performance plateaus around 100k rows-per-Type for searches with multiple constraints.

- Refactored Bubble app + cost optimization
Frequently asked questions
- Are my Bubble Privacy Rules actually working?
- Often not. Default state on new Data Types leaves data wide-open via the Data API. Even when rules are set, client-side filtering downloads the full unfiltered dataset to the browser. We audit rules, scopes, and the Data API as part of every Bubble security review.
- How do I lower my Bubble Workload Unit bill?
- Most overspend comes from on-page searches that re-run on every state change, recursive workflows without termination, and bulk operations during user actions. We profile your app's WU usage and refactor the high-cost paths.
- Can I migrate off Bubble?
- Yes, but it's always a rebuild — Bubble's runtime is proprietary and there's no code export. We extract data via the Data API, redesign the data model in Postgres, and rebuild workflows in Node or NestJS. From $800.
