Questions
you might have.
What's a check?+
One check = one grader execution against one input. A typical harness run executes hundreds to thousands of checks. Personal's 50,000 covers roughly 25–50 full harness runs per month — enough for a serious solo developer's CI loop.
What happens if I hit the 50,000 check limit?+
You can opt in to metered overage at $0.005 per check (rounded up to the nearest 100). The dashboard surfaces a per-harness average so you can predict spend before triggering a run. Or you can talk to us about Enterprise.
Why no free tier?+
Pistachio's COGS is real (LLM judge calls aren't free) and we want every signup to be a real customer. The public demo runner on the homepage does the awareness job a free tier would otherwise do — try any harness without signing up.
How do I connect my agent?+
Two ways. (1) MCP trace mode: install Pistachio as a Claude Code MCP tool and invoke harnesses from inside any Claude Code session. (2) Managed endpoint: paste your deployed agent's URL + auth header, and we hit it on a schedule. Both modes use the same harness library and grader engine.
What does Enterprise actually unlock?+
Vertical harnesses (legal, healthcare, FSI), SSO / RBAC, shared workspaces, audit logging, regulator-format signed reports, custom harness authoring, on-prem worker option, and a dedicated CSM. Vertical harnesses are co-built with one design partner per vertical.
