Agent Beacon: An Open-Source, Self-Improving Memory Layer for AI Coding Agents
Agent Beacon is an open-source memory layer that captures coding session history across multiple AI harnesses and turns them into reusable knowledge.
Agent Beacon is an open-source memory layer designed to capture session history across diverse AI coding assistants—such as Claude Code, Cursor, and Codex—and convert resolved workflows and debugging patterns into reusable knowledge. It builds a continuous feedback loop that bridges fragmented agent experiences and harness environments.

Core Features and Architecture
Agent Beacon supports local-first environments and cross-harness portability, recording traces and context generated during agent execution into structured memory units.
- Multi-Harness Support: Compatible with over 20 major coding agents and harness environments including Claude Code, Cursor, Codex, and OpenCode.
- Self-Improving Feedback Loop: Learns from resolved bugs and successful fix patterns during development to inform subsequent sessions.
- Open Source and Local-First: Released under the MIT license, providing flexible options to link local environments with remote storage.
Installation and Usage
Agent Beacon can be easily installed and run via Homebrew or official releases. Interactive endpoint configuration and authentication are managed through the provided scripts.
# Install via Homebrew
brew install asymptote-labs/tap/beacon
# Initialize and run
beacon.sh
It supports both managed cloud options and local-only storage, allowing developers to adapt it to team environments or individual workflows.
Conclusion
As the adoption of AI coding agents grows, session context loss and repetitive prompt configuration remain common challenges. Agent Beacon provides a practical alternative by unifying fragmented agent knowledge into a single memory layer.
