Instead of OpenLIT
OpenLIT alternatives
OpenLIT brings LLM tracing, evaluations, prompt management, and cost tracking together in an open-source platform built on OpenTelemetry. It can capture calls, tools, and retrievals; evaluate production traffic or experiments; manage versioned prompts; and compare models by latency, tokens, and cost. Its self-hosted OSS plan is free, with unlimited usage, users, projects, and environments. It supports Linux, macOS, Windows, web, and API use, and can accept OTLP data through Docker Compose or Kubernetes Helm deployments.

Readers may look elsewhere if they need a different focus, such as replaying captured agent runs, broad application monitoring, or tools for building and automating AI coworkers. OpenLIT covers a wide set of LLM workflows, but its Fleet Hub lists single-cluster collector monitoring, and its cloud offering is still coming soon, with pricing and features to be shared at launch. When switching, weigh whether the alternative covers the tracing and evaluation work you need, how it handles deployment and access, and whether its specialized tools or paid plans fit your workflow better than OpenLIT’s free self-hosted option.
