Choose beacon.sh if

Developers and engineering teams using several AI coding agents who want shared, reviewed memory and a full record of agent activity.

  • MIT-licensed core that runs locally without lock-in to one harness
  • One timeline for every agent and machine, including token spend
  • Turns repeated walkthroughs into skills every agent can reuse

Look elsewhere if: Teams that only need a shared knowledge store for agents and people, or want to train their own models from traces (Context Engine, Overmind).

Choose Radar if

Platform and DevOps teams that want a free open-source Kubernetes UI and a safe way to give AI agents cluster context.

  • Fully featured open-source build under Apache 2.0
  • Single binary and desktop app for macOS, Windows and Linux, no account needed
  • Read-only MCP endpoint lets agents inspect clusters safely

Look elsewhere if: Teams that need full-stack metrics, logs and APM in one hosted suite (Datadog, Dynatrace).
