Fix
Reload the tab
Ctrl/Cmd + R. If the project reloads, continue working.
Check localStorage
If the project is gone, Bolt saves state in browser localStorage. Clear cache only as a last resort.
Start fresh if needed
If lost: rewrite the founding prompt from scratch, keeping it shorter this time. Export to GitHub more frequently going forward.
Prevent this next time
Export to GitHub every 30 minutes. If Bolt seems slow, simplify your prompt — complex multi-feature requests can cause timeouts.
Frequently Asked Questions
Usually no. Bolt saves to localStorage. Try reloading first. If that fails, check if you pushed to GitHub recently.
Export to GitHub frequently. Keep prompts focused on one feature at a time.
