openlit is queued for analysis. Crawling candidates and ranking them takes a few minutes. This page updates itself when the list exists — you can also come back later.
What is known so far comes from the other direction:
These projects were analysed and named openlit among their alternatives. The relationship is not symmetric — how openlit rates them is a separate judgement, made when openlit is analysed in its own right.
calls openlit “Choose when you want OpenTelemetry-native observability plus GPU monitoring and guardrails in one platform.”
🪢 Open source AI engineering platform: LLM evals, observability, metrics, prompt management, playground, datasets. Integrates with OpenTelemetry, LangChain, OpenAI SDK, LiteLLM, and more. 🍊YC W23
calls openlit “Choose if you want OpenTelemetry-native LLM/agent tracing and evals without Opik's server dependencies.”
Debug, evaluate, and monitor your LLM applications, RAG systems, and agentic workflows with comprehensive tracing, automated evaluations, and production-ready dashboards.
calls openlit “Choose it for OpenTelemetry-native AI agent tracing/evaluation without MLflow's model registry, experiment tracking, and deployment features.”
The open source AI engineering platform for agents, LLMs, and ML models. MLflow enables teams of all sizes to debug, evaluate, monitor, and optimize production-quality AI applications while controlling costs and managing access to models and data.
calls openlit “Choose when you want OpenTelemetry-native LLM/agent tracing and evals with broad framework auto-instrumentation.”
AI Observability & Evaluation
calls openlit “Use instead if you want a self-contained AI observability platform (UI + monitoring) rather than only emitting OTel to your own backend.”
Open-source observability for your GenAI or LLM application, based on OpenTelemetry
calls openlit “Choose when you are focused specifically on LLM application observability and want prompt/guardrail/evaluation tooling, not general infra APM.”
SigNoz is an open-source, OpenTelemetry-native observability platform for your team and their AI agents. Get logs, metrics, and traces in one tool with features like APM, distributed tracing, log management, infra monitoring, etc. Combined with SigNoz MCP and a native AI teammate (in SigNoz Cloud) it helps you build more resilient apps.
calls openlit “Choose for dedicated LLM observability/tracing and evaluations when you don't need infrastructure log and metric storage.”
Open source observability platform for logs, metrics, traces, frontend monitoring, pipelines and LLM observability. A sophisticated, simple and highly performant alternative to Datadog, Splunk, and Elasticsearch with 140x lower storage costs and single binary deployment.
