A few useful answers.
Does Free need an account?
No. Free runs locally without an account or source upload. You get 30 lifetime scans with eligible fixes included. A scan counts whether or not you apply a fix.
Can I evaluate Fettl on a commercial repository?
Yes, for a time-limited evaluation. Ongoing commercial production use requires an active Pro entitlement or another written commercial agreement.
Is Pro priced per repository?
Pro is for one named developer across the repositories they are authorized to work on. It is not a shared team license.
Will Fettl automatically fix everything?
Fettl automatically applies eligible deterministic fixes and verifies the result. Your agent can act on other findings. You still decide architecture, public APIs, and product behavior.
What’s available now, and what’s planned?
Free and Pro cover local checks and eligible fixes. Pro adds automatic agent hooks and CI tools. Shared team administration, Enterprise plans, hosted history, dashboards, managed GitHub workflows, and model-assisted repair are planned.
How do I activate existing Pro access?
Run fettl login in your terminal, then sign in through your browser. Pro access is currently available by request.
