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 telemetry.dev if
Small teams building AI agents who want affordable tracing, cost tracking, prompt management and evals in one OpenTelemetry-based tool.
- Standard OpenTelemetry avoids proprietary instrumentation lock-in
- Free plan needs no credit card
- Simple per-workspace pricing with unlimited seats on Team
Look elsewhere if: Organizations that need self-hosting, compliance paperwork or full-stack infrastructure monitoring (Datadog, Sentry).
