Team Budget & Governance
Portkey gives each developer or team a virtual key with a USD or token budget. When the cap is hit, the key automatically expires — blocking further spend rather than just reporting it. As a managed SaaS, it requires no self-hosting, and routes Claude Code, Cursor, and other tools through a single governed gateway.
- Enforced per-key caps in USD or token count, with alert thresholds
- Custom reset windows — 1 to 365 days via the API (
periodic_reset_days: 1for daily); the dashboard presets cover weekly and monthly - Workspace-level budget & rate-limit policies for org-wide governance
- Note: hard budget enforcement is an Enterprise-plan feature; lower tiers get observability only
