Respan
Respan, formerly Keywords AI, brings model routing, tracing, evaluations, and prompt management into one developer platform. It helps teams inspect model calls, compare outputs, and manage gateways. Plans differ in log retention, evaluation scores, throughput, and collaboration features; using it still requires an AI application to instrument.
Free; Team $199/month equivalent billed yearly; Enterprise by quote.Is Respan right for you?
Good for
- Developers who need model routing and evaluation alongside tracing and cost visibility.
- Combines a model gateway with tracing, evaluations, and prompt management.
- Tracks request costs, tokens, latency, and inputs/outputs for investigation.
Keep in mind
- Default retention is seven days on Free and 30 days on Team.
- Team’s displayed price requires yearly billing; extra logs, scores, and seats have separate rates.
- Gateway throughput is tiered: the table lists 412 requests/minute on Free and 8,400 on Team.

Choosing a plan
Instrument a small workflow on Free and check whether its retention and scoring allowance cover your evaluation cycle. Compare Team when you need longer history, more scores, and higher throughput; account for additional logs and seats.
