About

Respan is an LLM engineering platform for tracing, evaluating, optimizing, deploying, and monitoring AI agent traffic through a gateway and observability dashboard. It logs requests, traces spans, tracks cost and usage, supports prompt versioning and rollout logic, and provides evaluation workflows with rule checks, LLM judges, and human review.

The free plan includes the full platform with 100k logs, 1k scores, 5 datasets, 2 evaluators, and 5 prompts. It is aimed at teams building production AI applications that need gateway routing, trace inspection, metrics, alerts, and evaluation workflows with concrete usage limits.

Feature parity 85%

This free tier is genuinely usable rather than a tiny teaser: it includes the full platform plus meaningful monthly quotas for logs, scores, datasets, evaluators, and prompts, and the page explicitly says no credit card is required. Compared with the $199/month Team plan, it looks like roughly a quarter of the paid value, so about $50/month is a fair estimate for the practical capability on offer.
