Is sipi.bot Free?
Short answer: the core is free — it's MIT-licensed open source and you can self-host it forever. The hosted plans are what cost money, and they're flat-rate.
What's free
The entire decision engine — MIT-licensed on GitHub, free to self-host forever.
The playground: run live transaction checks without a key or signup.

What's paid
Hosted plans (Team $99/mo, Business $499/mo) add the live dashboard, the managed approval queue, and timestamped audit-log storage.
Both hosted plans are flat-rate with unlimited transaction evaluations — no per-call fees, no metering, no overage tiers.
How to start for $0
Self-host the MIT core, or use the playground to see the decision engine live. When you need the dashboard and approval workflow, the paid plans are flat and predictable.
