The Bubble SaaS Architecture Mistakes We Fix Most Often
We receive more rescue project enquiries than new build enquiries. Fifteen architectural mistakes appear in almost every Bubble app we are asked to rescue. An honest catalogue of what bad Bubble architecture looks like in production — and how we fix it.
The Problems We See in Every Bubble App We Are Asked to Rescue
We receive more rescue project enquiries than new build enquiries. Founders who built their own Bubble app or worked with a junior developer reach a point where the app is slow, insecure, hard to extend, or actively losing them customers. Fifteen problems appear in almost every rescue engagement. This is an honest catalogue of what architectural mistakes look like in production.
What Bad Bubble Architecture Looks Like
| Mistake | Symptom | Root Cause | Our Fix |
|---|---|---|---|
| No workspace isolation | Users can see other users’ data | Privacy rules never configured | Add workspace field + privacy rules to every type |
| :filtered by everywhere | App collapses at 200 workspaces | Performance never designed | Replace every :filtered by with search constraints |
| Counts on page render | Dashboard takes 8+ seconds to load | No denormalisation | Add counter fields to Workspace; update on every change |
| Billing from redirect URL | Customers who paid have no access | Webhooks not implemented | Implement all 6 webhook events as source of truth |
| Roles on User record | All users see admin-level data | Role scope not thought through | Move roles to Membership; scope to workspace |
| Static data in data types | Status dropdowns trigger DB queries | Option Sets never used | Convert all static enumerations to Option Sets |
| Frontend workflows for heavy ops | Operations fail when browser closes | Architecture not designed | Move to backend API workflows |
| No soft delete | Accidental deletions are unrecoverable | Not planned in data model | Add is_deleted field; implement restore workflow |
| Hardcoded plan limits | Changing pricing requires code changes | Plan data in workflows not data | Create Plan data type; move all limits there |
| Missing error handling | Silent failures, confused users | Errors never designed for | Add error detection + ErrorLog + user messaging |
| All data loaded on render | Pages slow on mobile | Pagination never implemented | Add pagination to all repeating groups |
| No audit trail | Cannot investigate what happened | Not designed in data model | Add AuditLog with append-only privacy rule |
| API keys in visible fields | Security credentials exposed | Never understood security model | Move to private API Connector credentials only |
| No branch strategy | Features break live app | Building directly in live | Establish dev branch; deployment process |
| No documentation | Next developer cannot understand app | Never written | Architecture document + workflow dictionary |
Architect’s Note: An Architecture Audit Can Save Your Product
If your Bubble app has any of these symptoms, an architecture audit is the right first step. We assess every data type, every workflow, every search expression, and every privacy rule against the standards above. We deliver a prioritised remediation plan with effort estimates. Most rescue projects become 80% resolved with targeted fixes rather than complete rebuilds.
Work With a Bubble Architect
Most developers build Bubble apps. We architect them. Data models designed for scale, multi-tenant security built from day one, Stripe billing that never fails, and workflows engineered for performance. This is what a Bubble Architect delivers.
