Does sipi.bot Have a Free Tier?
There are two genuinely free ways to use sipi.bot — self-host the MIT core, or run live checks in the playground. There's no hosted free tier.
The free options
Self-host: the MIT-licensed core runs your rules forever at $0.
Playground: evaluate any transaction live — no key, no signup.
What's not free
Hosted plans are flat-rate: Team $99/mo, Business $499/mo. They add the dashboard, approval queue, and stored audit log.
Which should you pick?
Engineers who want the control plane in their own infra: self-host. Teams that want the dashboard and approval workflow without ops: hosted.
