Hi everyone! 
I want to go deeper into debugging performance issues and share advanced techniques that can help you troubleshoot and fix bottlenecks in your app.
- Use Bubble’s Performance Monitoring Tools
-
Go to Logs → Server Logs / Capacity
→ You can see which workflows are taking too long, how often they’re triggered, and what actions are heavy. -
Use Step-by-Step mode to debug slow workflows.
-
In Preview mode, use the “Inspect” tool to track when and how elements are rendered.
Backend Workflow Tricks-
Schedule on a List vs Recursive:
Use recursive workflows instead of “Schedule API on a List” when dealing with large datasets. -
Throttle API Calls:
Add small delays (Schedule API workflow +5 seconds) to reduce load spikes.
External APIs & Plugins-
Minimize use of heavy plugins. Some third-party plugins are not optimized and slow down page loads.
-
If you’re using external APIs (like OpenAI, Stripe, Airtable, etc.), cache responses where possible.
4. Use Option Sets for Static Data
-
For dropdowns, categories, or settings that don’t change — use Option Sets instead of storing them in the database.
-
They load faster and don’t count as database reads.
5. Clean Up Unused Workflows & Elements
-
Delete any unused workflows, popups, test elements, or temp buttons. Even if they’re hidden, Bubble still renders some of them.
-
Use reusable elements for repeated UI components (like navbars, cards, footers).
6. Repeating Group Optimization (Advanced)
-
Use “Full List” only if necessary — otherwise, stick to “Vertical Scrolling” or pagination.
-
For dynamic filters, combine filters in the search itself instead of doing them afterward (which runs on the client side and slows it down).
7. Consider Bubble’s Dedicated Plans
-
If you’re hitting performance limits often, consider moving to a dedicated plan or boosting your server capacity.
-
Check your app’s capacity usage in the Bubble dashboard to see if that’s what’s holding you back.

Thank you.
