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 Polylane if
Small platform and backend teams running on Cloudflare, Vercel or AWS who want an AI first responder without hiring an SRE.
- Free plan for two members and two cloud accounts
- Read-only Cloudflare access with no full-access option offered
- MCP and API reads are unlimited on every plan
Look elsewhere if: Teams that need a mature, full observability suite with predictable usage pricing (Datadog, Sentry).
