Why Pro is the most popular pick
Not because of marketing — because it's the first tier that unlocks what most builders actually need from a grader API:
- REST API access. Every paid plan below Pro runs browser tools only; Pro is the entry tier for calling the engine in CI/CD, scripts, or backend pipelines.
- 10,000 requests/hour. About 160× the Free tier — enough for production workloads without the per-seat overhead of Team.
- No seat pricing. A fixed monthly price whether you run 10 checks a day or 10,000 — predictable for individual builders and small teams.
API credits explained
API limits reset hourly and are shared across the checker, scanner, detector, and audit endpoints. Browser tools are unlimited — they never count against your API quota.
