Visit keywordsai.co →DocsPricing
Respan is an LLM engineering platform that combines an AI gateway with observability and evaluation tools. Its gateway routes requests to 1,000+ models through a unified endpoint with automatic fallbacks, response caching, load balancing, and spend limits. The platform also provides tracing of LLM calls, tool runs, and agent turns as spans; monitoring dashboards for requests, errors, cost, latency, and tokens with threshold alerts; and automated evals using LLM judges, deterministic checks, and human review against datasets sampled from production traffic. It also includes prompt management with versioning and deployment, red-teaming campaigns, and an open-source gateway. Backed by Y Combinator (W24) and Gradient Ventures.
