Limits worth knowing in Polymet
- Credits are spent by AI model usage per message, so large builds use more than short edits; nothing is billed past zero and generations stop when credits run out.
- Custom domains, code download, GitHub export, removal of the Polymet badge and premium models are Pro-plan features.
- A Keep Alive option at $8 a month keeps a finished project online after a paid plan is cancelled, with 300 credits a month on top of the free 500.
- Unused free credits do not carry over; paid plan credits roll over for 30 days after each renewal. The product is a browser app only.
