Description

OpenMuse is an open source personal AI agent with browser, terminal, and file access, letting it actually carry out tasks on a user's machine (navigate the web, run commands, read/write files) rather than only chat. It is aimed at developers and technical users who want a self-hostable, inspectable AI agent rather than a closed, cloud-only one.

LangWatch is an open-source, framework-agnostic platform for testing, evaluating, observing, and optimizing AI agents and LLM applications. It uses simulation-based testing with real-user text and voice conversations, LLM-as-a-judge evaluations, red teaming, and OpenTelemetry-native observability to catch issues and prevent regressions. It supports collaboration between technical and non-technical teams and can be deployed as cloud, self-hosted, or hybrid.
