observability

An application observability facade for the most popular observability tools. Think SLF4J, but for observability.

Enterprise-ready, Git native feature management solution

Aya is an eBPF library for the Rust programming language, built with a focus on developer experience and operability.

AI observability platform for production LLM and agent systems.

An AI Gateway, registry, and proxy that sits in front of any MCP, A2A, or REST/gRPC APIs, exposing a unified endpoint with centralized discovery, guardrails and management. Optimizes Agent & Tool calling, and supports plugins.

The missing DevTools for Claude Code — inspect session logs, tool calls, token usage, subagents, and context window in a visual UI. Free, open source.

High performance Java APM. Powered by ASM. Try it. Test it. If you feel its better, use it.

The platform for LLM evaluations and AI agent testing

🕹️ Open-source, developer-first LLMOps platform designed to streamline prompt design, version management, instant delivery, collaboration, troubleshooting, observability and more.

SRE Agent - CNCF Sandbox Project
