Limits & error codes
Quotas, soft ceilings, and machine-readable error codes.
Plans enforce soft and hard limits. Soft limits return warnings in response headers; hard limits return structured errors.

|---|---|---|
| Requests / minute | 4,000 | 5,000 |
| Concurrent isolates | 200 | 250 |
| Deploy size | 25 MB | 40 MB |
| Log retention | 7 days | 30 days (paid) |
Error codes
| Code | HTTP | Meaning |

| rate_limited | 429 | Retry with backoff |
| quota_exceeded | 402 | Upgrade or reduce traffic |
