Having struggled with Bubble’s editor for months, I’ve slowly figured out the most optimal settings to stop it crashing so often. Roughly ordered by effectiveness:
- Compartmentalize your app
Break your app into reusable elements and separate pages to reduce load per editor session and improve maintainability. - Use Chrome in Incognito mode - this halved my memory usage
Disables extensions/plugins that cause memory bloat or conflicts—cleaner environment for editing. - Keep minimal Bubble windows/tabs open
Each editor tab consumes resources; fewer tabs = better performance and less lag. - Close or pause other heavy apps/processes
Free up CPU and RAM to keep the editor responsive, especially during complex workflows. - Use Bubble’s debugger sparingly
Debugger adds runtime overhead; enable only when actively troubleshooting. - Regularly update and remove unused plugins
Outdated or unnecessary plugins add complexity and bloat and slow editor load times.
I’ve tested a lot of different browsers and settings, and this is what I’ve found works best for me. Hopefully this helps someone else working on heavy Bubble apps and dealing with constant editor crashing or memory issues.
With the above changes I was able to get the bubble editor from 8gbs per tab down to 3gbs and now the editor rarely crashes whereas before I could barely go 60 minutes - and after the recent “updates” that was down to 15 minutes. The biggest change was using incognito mode - I think some extensions may have been causing issues in the new editor.
The GPU in my tests never gets above 5% usage. CPU briefly spikes to 100% on new page loads and memory seems to hover around 3gbs per editor tab which no longer causes crashing.
If you have other suggestions please post a reply.
