Our take: Choose Respan if you build LLM agents and want one gateway to 1,000+ models plus tracing, evaluators and alerts, starting on a free plan with 100k logs.
Main limitation: The free plan is capped at 100k logs, 1k scores and 5 datasets, and the Team plan costs $199 per month billed yearly.
Is Respan right for you?
Choose Respan if you build LLM agents and want one gateway to 1,000+ models plus tracing, evaluators and alerts, starting on a free plan with 100k logs. Based on the vendor's documentation, not on a hands-on test.
Best for: Teams building LLM agents
Also a good fit for
- Startups needing LLM observability
- Engineers managing multi-model routing
Consider another tool if free plan is capped at 100k logs
Or if
- Team plan costs $199/mo billed yearly
- Enterprise requires talking to sales

What Respan does, and where it stops
Gateway with automatic fallbacks
Falls back to the next model when one errors or rate-limits. Keeps agents up during provider outages.
Response caching
Serves repeated identical requests from a cache. Cuts cost and latency.
Spend limits and rate limits
Sets budgets and rate limits per key, customer or org. Prevents runaway spend.
Tracing and logs
Records every LLM call, tool call and agent step with cost and latency. Debugging with full context.
