Rolling Back to Previous Versions in Lovable

Why you need to roll back versions in Lovable

Lovable's AI makes changes autonomously in Agent Mode, modifying multiple files across your project in a single task. Sometimes these changes introduce bugs, break existing features, or take the project in a direction you did not intend. The AI can also get stuck in a loop where it tries to fix a bug, introduces a new one, and burns through credits without making progress. Version history is your safety net. Lovable saves a snapshot of your project after every AI interaction, so you can always go back to a known working state. This is especially important because there is no traditional undo button — once the AI modifies your code, the only way to reverse it is through version history or GitHub. A common frustration is the Restore button appearing greyed out. This happens when the project is mid-task (the AI is still processing) or when there is a sync conflict with GitHub. Understanding why this occurs and how to work around it saves time and prevents unnecessary credit spending on re-prompting.

• AI-generated changes broke existing functionality — a new feature inadvertently removed or changed working code
• The AI entered a fix loop — it keeps trying to repair a bug and making things worse with each attempt
• Accidental scope creep — you asked for a small change but the AI modified unrelated components
• Restore button greyed out — the project is processing a task or has a GitHub sync conflict
• Lost work after browser tab closed — the AI was mid-task when the session ended

Error messages you might see

Before you start

• A Lovable project with at least one previous AI interaction in the chat history
• No currently running AI task (wait for it to finish before restoring)
• If GitHub-connected: no unresolved merge conflicts on the default branch

How to fix it

// You need the code from a previous commit but cannot use Lovable's Restore
// Open GitHub → your repo → Commits → find the working version

// Option 1: Use GitHub's Revert button on the bad commit
// This creates a new commit that undoes the changes
// Option 2: Copy code from the old commit and paste it into Lovable
// Open the file in the old commit on GitHub, copy the contents,
// then paste into Lovable's Dev Mode editor
// Option 3: Prompt Lovable with the specific code to restore
// "Replace the contents of @src/components/Dashboard.tsx with this code:
// [paste the working version from GitHub]"

3## Version Management Rules
4
51. Before making large changes, always confirm the plan in Plan Mode first.
62. Never modify more than 3 files in a single task without explicit approval.
73. If a fix attempt fails twice, STOP and ask the user before trying again.
84. Preserve all existing functionality when adding new features.
95. Do not remove or rename existing components unless explicitly asked.

11## Recovery Checklist
12
13If the project enters a broken state:
14- Suggest using version history to restore the last working version
15- List which files were changed in the most recent task
16- Explain what each change was intended to do
17- Offer to revert specific files instead of the entire project
18
19## Protected Files (never modify without explicit permission)
20- src/App.tsx (main routing)
21- src/integrations/supabase/client.ts (Supabase config)
22- index.html (entry point)
23- vite.config.ts (build config)

Best practices to prevent this

• Before making large AI changes, duplicate your project as a safety backup — you can always go back to the duplicate
• Use Plan Mode to review what the AI will change before executing — this costs one credit but can save dozens by avoiding bad changes
• After every successful feature addition, note the version in chat with a comment like 'Working version — login feature complete'
• Add an AGENTS.md file with rules that prevent the AI from making overly broad changes to reduce the need for rollbacks
• Connect your project to GitHub early — it provides a full commit history as an independent backup beyond Lovable's version history
• If the AI enters a fix loop (repeatedly failing to fix the same bug), stop and revert immediately instead of burning more credits
• When restoring a version, verify the live preview works before making any new changes on top of the restored code
• For critical projects, test in a duplicated project first before applying changes to the production version
