Beacon
Open-source, local-first memory and telemetry layer for coding agents: captures sessions across Claude Code, Cursor, Codex, OpenCode and 20+ harnesses and turns reviewed lessons into reusable skills via MCP or Agent Skills.
💲 Open source self-hosted: $0. Beacon Cloud: $0 (50 findings). Cloud Pro: $20/mo billed annually (unlimited findings, agent memories over MCP). Enterprise custom. Source: beacon.sh (checked Oct 22, 2026).
Pros & cons
👍 Pros
- Works across 20+ coding agents, so knowledge isn't locked to one tool
- MIT-licensed and local-first; nothing leaves your machine unless you configure it
- Review-gated memory: lessons are approved before agents reuse them
👎 Cons
- Interactive setup defaults to Beacon Cloud (local is an explicit opt-out)
- Memory features beyond 50 findings need the paid plan
