Lovable users report 400 credits in two weeks lost to agent regression loops

What happened

An April 2026 engineering teardown of Lovable credit burn documented the regression loop: the agent breaks something else while fixing the thing you asked, so every loop costs credits and returns net-zero progress. Users on the same seat reported multi-million-token auth spirals and 400 credits burned in two weeks on a Pro plan. The author's conclusion: the fix is not better prompts - it is stopping the AI, locking the architecture, and patching by hand.

Causal vector

Per-action credit pricing plus context loss: each fix regresses another component, billing a full loop for zero net progress

How a spend firewall would have helped

A regression loop charges twice - once to break, once to 'fix'. Budgets need to stop per task, not per month: a per-task spend cap makes the second full rewrite of working code a blocked transaction instead of a billable one.

The six rule types that contain this class of failure

Per-transaction cap

Any single spend above your ceiling is BLOCKED before it moves.

Daily total

Cumulative spend across all agent calls, bounded per day.

Velocity limit

Stops runaway retry loops — the #1 cause of overnight losses.

Merchant allowlist

Only approved destinations can ever receive funds.

Category rules

Flag high-risk classes (crypto, infra, refunds) for review.

Approval threshold

Above a value, the action waits for a human.
