Lovable stuck in a fix loop and burning credits? Do this

If Lovable keeps "fixing" the same error and it keeps coming back, stop retrying after the second attempt. A loop means the root cause hasn't been found, and every new patch adds code that hides it further. Switch to Plan mode to investigate without changing code, give Lovable the exact error instead of a description, and revert to the last working version if the fixes have tangled things. That usually costs less than three more blind tries.

This guide explains why loops happen, what retries actually cost on Lovable today, a six-step way out, and how to cap spending so a bad afternoon can't drain your balance.

Why does Lovable get stuck fixing the same thing?

Most loops follow one of these patterns:

• The error isn't in the code. A missing secret, a database policy that blocks a read, a webhook pointing at the wrong address or an expired third-party key all produce errors in your app, but the fix is a setting. The AI keeps rewriting code because code is what it can change.
• The fix treats the symptom. "Cannot read properties of undefined" gets a null check, the screen stops crashing, and the data still doesn't load. The next prompt reports a new error in a different place.
• Each attempt changes more than it should. By the fifth try, the component has three versions of the same logic and nobody, human or AI, can tell which one runs.
• The request was too big. "Add teams, invites and billing" in one prompt touches so many files that any failure is hard to isolate.

Lovable's own debugging guide says it plainly: repeated blind fixes pile up code that hides the real problem, and switching to Plan mode after one or two failed attempts is usually faster.

What does each retry cost?

The pricing has changed several times, so here is how it works according to Lovable's current docs:

To see what a specific message cost, open the More options menu under the response and read Credits used. Long Build mode runs pause for a "credit check-in" once a single message crosses a threshold (20 credits by default), which you can raise or turn off in your account preferences.

The trap: once the free fixes are used up, a loop of Build mode retries is the most expensive way to debug.

How do I break the loop?

1. Stop and note where it started

Scroll back through the chat to the last response where the app worked. Open Show history at the top of the editor and preview that version to confirm. Write down what you asked for right after it.

2. Get the real error

A screenshot of a broken page isn't enough. Collect at least one of these:

• The first red line in the browser console (right-click, Inspect, Console).
• The failing request in the Network tab: its address and status code (401, 403, 404, 500).
• The backend log entry from More → Cloud → Logs, filtered to errors.

3. Investigate in Plan mode

Switch the chat to Plan mode so nothing changes while Lovable investigates. Prompts that work well:

What is the root cause of this error? Show me the relevant code and explain it before proposing a fix.
What solutions have we already tried for this error? List them so we don't repeat them.
Is this caused by code, or by a setting, secret or database policy?

The third question matters most. If the answer is a setting, fix the setting yourself and skip the code change entirely.

4. Decide: revert or keep

If the last few fixes added code that isn't needed, revert. Hover over your own message from before the loop, click Edit message, rewrite it more precisely, and confirm Revert and resend. Or revert from version history.

Two things to know before reverting: it restores code only, not database data, and it redeploys edge functions to match. If a prompt in the loop created tables or changed records, those stay.

5. Rebuild in small steps

Tell Lovable what you did ("I reverted to before the invite feature. Let's add it again in smaller steps.") and ask for one piece at a time: the table, then the form, then the email. Test each in the preview before the next.

6. Write the lesson down

When it's solved, ask Lovable to summarize the cause and the fix and add it to the project knowledge, so the next session doesn't repeat it.

How can I tell the problem is a setting, not code?

These errors almost always point outside the code:

• permission denied for table or an empty list where you expect data: a row-level security policy. See our guide to Supabase row level security in Lovable and Bolt.
• A 401 or 403 from an edge function, or "missing API key": a secret that isn't set. Our edge function errors guide walks through it.
• Login that works in preview but not on your domain: auth redirect URLs.
• Payments that succeed but don't unlock anything: the webhook, covered in Stripe paid but no access.

How do I cap what a loop can cost?

• Set usage limits. Lovable lets workspace admins set credit limits and low-balance alerts for the workspace, individual projects and members. A project limit is a cheap safety net.
• Keep the check-in on. Leave the long-running check-in at a level you'd want to be asked about.
• Bookmark stable versions in history after each feature works, so you always have a known-good point to return to.
• Use Chat or Plan mode for questions. "Why is this slow?" doesn't need Build mode.

Quick answers

Does reverting give my credits back? No. Credits pay for work already done, so messages you revert still count.

Is Try to fix always free? Only the first 10 on your account, each refilling 24 hours after use. After that it's normal build usage.

Should I start a new project instead? Rarely. Reverting to the last working version keeps everything that worked up to that point.

How many retries before I stop? Two. After that, investigate in Plan mode or get another pair of eyes.

When it's time for a person

If you've reverted, planned and rebuilt and the same thing still breaks, the cause is probably structural, and a human review is cheaper than more credits. Run the free health check, see how we fix Lovable apps, or tell us where you're stuck.
