About OpenObserve
OpenObserve is an open source observability platform for logs, metrics, traces, analytics, Real User Monitoring, session replay, pipelines, SLO, and LLM observability. It lives in the cloud native infrastructure ecosystem and is described as an alternative to Datadog, Splunk, and Elasticsearch. The project is built in Rust, ships as a single binary, and uses Parquet columnar storage with an S3 native design.

About codeburn
CodeBurn is a free, open source, local first tool that tracks AI coding token usage and cost across 41 tools and agents, including Claude Code, Cursor, Codex, Gemini, and Grok. It is written in TypeScript, licensed under MIT, and lives in the developer tools and observability ecosystem as a command line utility with optional desktop surfaces. Every surface reads the session files that the supported tools already write to disk, so CodeBurn acts as one source of truth rather than a separate collection layer.
