PMB

In plain words

PMB is a dev tool that provides local memory for coding agents while displaying usage visibility. Designed for developers working with AI-assisted coding, it enables agents to retain and access information across sessions. The tool stands out by making memory usage transparent, allowing developers to see how their coding agents are utilizing stored data, which helps with debugging and optimization of agent behavior.

From the sources

PMB gives Claude Code, Cursor, Codex and Zed persistent project memory through MCP. It stores decisions, lessons, goals, recent work, project facts and docs in one SQLite workspace on your disk. No cloud, no API keys, no LLM call on the read path. It is open source, offline-first, inspectable/exportable, with a local dashboard and honest impact tracking so you can see which memories actually help.

Decisions, lessons and project facts live in one SQLite file you own. Fed back to Claude Code, Cursor, Codex and Zed through MCP. Offline, no API keys, no cloud, recall in ~35 ms. Hooks inject the right memory before the model thinks, and journal the agent's work after, no LLM call on the read path, no tool the agent has to remember to call. Every message is classified in sub-millisecond; the matching lessons, decisions and project overview are fetched for the agent before it reasons. The MCP tool returns instantly. SQLite first; the embed and LanceDB vector insert run on a background thread, never blocking the turn. BM25 + dense vectors + entity graph + optional rerank, fused with…from pmbai.dev

  PMB is a local-first memory system for AI coding agents, running on MCP and storing data with SQLite and LanceDB. It preserves project context, decisions, and preferences across sessions and tools. I created it because coding agents frequently lose valuable context between sessions, especially on long projects. So, I'd love feedback from those who use coding agents regularly. What do you think should be auto-remembered versus what should always need explicit confirmation?

  Homebrew 6.0.0▲1,481

  Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

  Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
