Start free. Pay as you go.
Commit when it works.

Free is for building and trying things: up to 3 projects and 3 members, 5,000 credits, 1 agent-hour, and 5 GB a month at no cost, with manual and scheduled agent runs, 1-day history, and community support. Add a card and you are on Pay as you go: 3 agent-hours, unlimited projects and members, custom domains, event-triggered agent runs, 30-day history, 6-month analytics, standard support, and usage beyond the allowances metered at $2.00 per 1,000 credits, $0.75 per agent-hour, and $0.15 per GB, with no monthly fee. Pro is $149 per month for the whole organization: 35,000 credits, 40 agent-hours, and 200 GB included, lower rates beyond that, 90-day history, 1-year analytics, a 99.9% uptime SLA, and priority support.

1,000 credits are $1 of AI hosted by Fimo: autonomous agent runs, edits made in Fimo Studio, and image generation. Building your site with your own coding agent runs on your own subscription and never uses credits. Free and Pay as you go include 5,000 credits a month, and Pro includes 35,000. Beyond the included amount, credits are $2.00 per 1,000 on Pay as you go and $1.00 per 1,000 on Pro.

When an agent works on your site it gets its own environment: a sandbox, a database branch, and a copy of your assets. An agent-hour is one hour of that environment being active. A typical run keeps it for about 30 minutes. Editing in Fimo Studio is never metered. Free includes 1 hour a month, Pay as you go includes 3, and Pro includes 40. Beyond the included amount, runtime is $0.75 per hour on Pay as you go and $0.33 per hour on Pro.

Everything it takes to serve your site: requests, image optimization, server functions, incremental regeneration, and builds. One number, no separate hosting meters. Free and Pay as you go include 5 GB a month, and Pro includes 200 GB. Beyond the included amount, bandwidth is $0.15 per GB on Pay as you go and Pro. The fine print, including fair use, storage, and database compute, is in the documentation.

Neither. Fimo bills at the organization level. Free covers up to 3 projects and 3 members; with a card on file, and on Pro, members and projects are unlimited. Only usage is metered, never seats.

Without a card on file, agent runs pause when the credits or agent-hours are used up, and public serving pauses if the bandwidth allowance runs out, until the next month or until you add a card. With a card on file you are on Pay as you go: nothing pauses, and usage beyond the allowances is metered at the pay-as-you-go rates.

It is a forecast for orientation, not a quote. The estimator turns your monthly visits into bandwidth at roughly 500 KB per visit, and your agent count and activity level into credits and agent-hours, then applies each plan's allowances and rates. Your real numbers depend on how heavy your pages are and what your agents actually do, and billing always follows measured usage.

Yes. Start on Free, add a card to use Pay as you go when you need it, and move the organization to Pro when you want the bigger bundle, lower rates, or production features. Changes apply immediately.

Premium stays active. Organizations on the legacy Premium plan are contacted directly and get an explicit choice in the Billing page of the app, with the exact terms and a deadline to answer. No new price is charged unless someone with billing access accepts it there, and an email alone never changes a subscription.
