Credits are metered based on your actual AI usage and the model used. Some models are more expensive, or consume more tokens, than others.
One site means one Astro project. If you have a monorepo with multiple Astro sites, each one counts separately, if added to Zero. A single repository with one Astro project counts as one site.
A content entry is a single file inside an Astro content collection — for example, one blog post, one changelog entry, or one page. Images, components, and configuration files do not count toward the limit.
AI credits power all AI features in Zero — the built-in AI agent, skills that run as audits, and pre-publish checks. Every plan includes a monthly credit quota that resets each billing cycle. If you run out of your quota, you can buy new credit packs (valid for a year) or enable automatic top-ups.
Connecting and using external AI agents like ChatGPT or Claude through Zero's MCP server does not consume your AI credits.
Nothing breaks. Your content stays safe in your GitHub repository, exactly where it always was. You just need to pick a plan to keep editing through Zero. Since Zero never touches your code, your site keeps working regardless.
Early adopter pricing is locked in for as long as your subscription stays active. You keep the 50% discount forever. It only goes away if you cancel and resubscribe later.
Zero currently supports the following models. New ones are added frequently.
