Beacon
Open-source memory so your coding agents stop forgetting everything.
Key facts: Beacon hit #1 on Product Hunt on November 2, 2026. It captures agent sessions across Claude Code, Cursor, Codex, OpenCode and 20+ other harnesses and turns them into a compounding knowledge layer, so every agent starts smarter than the last. Install it with the Beacon CLI on macOS, Windows or Linux.
Plans: Free to get started, with no credit card required, and open source. Check the official site for paid plans.
Best for: Developers who run coding agents every day and are tired of re-teaching the same lessons. Who should skip it: anyone who uses a single agent only occasionally.
