Frequently asked

Six questions, plain answers.

  • Why no per-seat pricing?

    Per-seat pricing punishes teams for collaborating. We charge a flat rate per tier and cap headcount and usage at sensible levels. Adding a viewer or a third reviewer should cost nothing — and on every tier here, it doesn't.

  • What happens when I hit a usage cap?

    You'll get a notification at 80%. At 100% we soft-throttle — execution and MCP calls queue with a small delay, but nothing breaks. We don't auto-bill overages. You can upgrade tiers from your dashboard whenever you're ready.

  • Can I switch tiers any time?

    Yes. Upgrades take effect immediately and are prorated to the day. Downgrades take effect at the end of the current billing period. No phone calls, no retention queues — switch from your dashboard.

  • Is annual billing available?

    Yes — 20% off (effectively 2.4 months free) on Pro, Team, and Agency. No clever tricks; the discount applies straight to the next renewal.

  • What about the self-hosted option?

    Genuinely free, MIT-licensed, and full feature parity with Pro. Deploy on your own Cloudflare account — your D1, your R2, your data. The trade-off: you run it, you patch it, community support only.

  • When will SSO, SCIM, and audit logs ship?

    When we have validated demand from a paying customer who needs them. We won't build enterprise plumbing speculatively — that's how SaaS pricing pages turn into 30-row checklists nobody uses.
