Open-source self-improving memory for AI coding agents
Beacon turns agent sessions across Claude Code, Cursor, Codex, OpenCode, and 20+ other harnesses into a compounding knowledge layer, so every agent starts smarter than the last. It captures every agent trace across your environment and turns activity into clear operational visibility. Get started for free at beacon.sh
One of my favorite things about Beacon is that it makes your coding agents smarter the more you use them.
For everyone in the Product Hunt community building and shipping with Claude Code, Cursor, Codex, or other coding agents, you've probably experienced how frustrating it is to solve the same problem multiple times across different sessions and tools!
Beacon learns from your past sessions, turns useful discoveries into reusable memories and skills, and makes them portable across all your coding agents.
I personally switch between multiple agents every day, and seeing them build on each other's work has been a game changer.
We're building Beacon in the open, it's completely free to get started, and I'd love to hear what you think!
