Released 2026-06-22. Public usage limits keep third-party traffic on your public surfaces from running up surprise costs — with clear visibility into where you stand.
Added
- Per-plan daily limits on public surfaces. Playgrounds, forms, visualizers, agents, streams, and webhooks now have daily limits on public, third-party-driven usage. When a resource reaches its limit it pauses for the rest of the day and resumes automatically at the daily reset, so a viral or abusive spike can't quietly run up your bill.
- “Public usage limits” card. Billing → Usage shows each surface's volume this month, its daily limit, and any resource that's currently paused.
- Refresh cache (playgrounds). A new toolbar button pushes your latest changes to the live public site immediately, instead of waiting for the cache to refresh on its own.
Changed
- Free-tier public AI uses your own key. On the free plan, AI in public agents (embed widget + webhook) now runs on your own provider key (BYOK) rather than FlowFn's. Paid plans are unchanged.
Notes
- Limits are generous and aimed at runaway / abusive traffic, not normal use. Need higher limits? Upgrade your plan or contact us.
