OpenMemory MCP
ContextForge is persistent, searchable memory for AI coding agents โ built on the Model Context Protocol (MCP).
Your AI assistant forgets everything when the session ends. ContextForge fixes that: save architectural decisions, naming conventions, and debugging context once, and any MCP client recalls it later with semantic search โ across sessions and across projects.
Works with: Claude Code, Claude Desktop, Cursor, GitHub Copilot, ChatGPT, and Windsurf.
Zim Wiki ContextForge.devZim Wiki is recommended for students, writers, researchers, and professionals who want a straightforward yet powerful tool for organizing their notes and managing projects. It is particularly suited for those who prefer a local application that doesn't rely on cloud services and who appreciate the ability to work offline with an open-source solution.
ContextForge.dev's answer:
ContextForge is memory that lives at the MCP layer, so it works across every AI coding agent at once โ Claude Code, Cursor, GitHub Copilot, ChatGPT, and Windsurf โ not just one. Save a decision once and any client recalls it later with semantic search. It goes beyond a note store: automatic git sync turns your commits and PRs into searchable knowledge, plus task tracking, snapshots, and team sharing โ all through a single MCP server you add with one command.
ContextForge.dev's answer:
Most memory tools are tied to a single agent or are just a key-value store. ContextForge is MCP-native, so it's portable across all your AI tools; it adds git sync so your codebase history becomes searchable context automatically; and it includes team features (shared spaces, collaborators) that solo-memory tools lack. Setup is one command, there's a genuine free-forever tier with no credit card, and paid plans start at just $9/month.
ContextForge.dev's answer:
Software developers and engineering teams who use AI coding assistants โ Claude Code, Cursor, GitHub Copilot, ChatGPT, Windsurf โ and are tired of re-explaining their project, architecture, and conventions every session. It fits solo developers working across multiple projects as well as small teams that need shared, persistent context.
ContextForge.dev's answer:
ContextForge was born from a simple frustration: AI coding agents forget everything the moment a session ends. Every new conversation meant re-explaining the same architecture, naming conventions, and past decisions. ContextForge was built to give AI agents a permanent, searchable memory through the Model Context Protocol โ so knowledge is captured once and reused forever, across sessions and projects. It even dogfoods its own memory to help build itself.
ContextForge.dev's answer:
Next.js 16 (App Router), React and Tailwind CSS for the dashboard, hosted on Vercel. Supabase (PostgreSQL) with pgvector powers the semantic vector search, and Deno edge functions serve the API. Embeddings use OpenAI text-embedding-3-small. The MCP client is a Node.js package (contextforge-mcp) on npm, implementing the Model Context Protocol.

Yeah, I'm a long time user/disciple of https://zim-wiki.org ; it was basically Obsidian but 15-20 years early. To do some of the things that are now trivially easy with Obsidian I learned scripting and such, so I'm familiar with this very weird coincidence/name collision. - Source: Hacker News / 4 months ago
I would recommend Obsidian to new users. I've been using Zim Wiki for years; back then there was nothing better available and I now can't be bothered to migrate formats. https://obsidian.md/ https://zim-wiki.org/. - Source: Hacker News / 4 months ago
And for those who are only vaguely familiar, this ZIM file format is not the same as the https://zim-wiki.org one. - Source: Hacker News / 4 months ago
I didn't know that Obsidian worked that cleanly; I occasionally flirt with it but have been using https://zim-wiki.org for about a decade longer, so my muscle memory is there. I keep looking for reasons to switch but so far nothing yet has done that? - Source: Hacker News / 5 months ago
Not quite shell -- but obligatory: I've been using http://zim-wiki.org for now .. decades? As my main driver for most everything in my life, including my personal and teaching website, custom template I made. jrm4.com. - Source: Hacker News / 6 months ago
