Observer is a powerful, local-first control plane for managing and observing AI coding agents. It provides unparalleled transparency into the exact tokens and costs billed by AI providers, including complex details like cache splits and long-context surcharges, across over 26 different coding tools. Designed with a strong emphasis on privacy, it operates entirely on your local machine with zero telemetry by default, ensuring your data remains private. Beyond cost tracking, Observer acts as a unified capture layer, normalizing activity from various AI tools into a single queryable schema, enabling developers to gain deep insights into their AI interactions, optimize usage, and prevent wasted spend. It also offers advanced features for teams, including an optional rollup server and a security/control layer for self-hosted LLM applications.
