Graphify

open sourceexplicit relation

Graphify is an open-source AI coding assistant skill that transforms folders of code, documentation, research papers, and images into queryable knowledge graphs. It works as a skill for Claude Code, Codex, OpenCode, and other AI coding assistants. Using tree-sitter AST parsing for 19 programming languages and Claude vision for documents and images, it builds NetworkX graphs with Leiden community detection, outputting interactive HTML visualizations and structured JSON for codebase exploration.

100% free and open-source under the MIT license ($0 software cost). Fully self-hostable with zero licensing fees for automated knowledge graph extraction and Graph RAG pipelines.

Grok-Wiki

open sourceexplicit relation

Desktop workspace that transforms local and remote git repositories into source-grounded wikis, architecture documents, and interactive Ask sessions. Integrates directly with existing CLI agents including Grok CLI, Claude Code, and Codex without requiring proprietary cloud infrastructure. Generates verifiable file citations, Mermaid diagrams, and Obsidian-compatible exports while ensuring private codebase data remains strictly on the local machine.

Free and open source (MIT); local-first execution with user-owned CLI/model access.

Codebase Memory MCP

84/100open sourceexplicit relation

Codebase Memory MCP is an MIT-licensed MCP server that turns a repository into a persistent code knowledge graph for AI coding agents. It gives Claude Code, Cursor, Codex-style agents, and other MCP clients structural queries for functions, classes, call chains, routes, and architecture, helping them explore large projects without repeatedly rereading files or relying only on broad search.

Free and 100% open source under the MIT License. Codebase Memory MCP has no licensing costs or subscription tiers; it runs locally as a standalone binary with embedded SQLite and Tree-sitter.Review →

GitNexus

85/100freemiumexplicit relation

GitNexus is a code-knowledge-graph and Graph RAG app for exploring repository structure before humans or AI coding agents make changes. Write-time source checks support graph/RAG and local-server signals, but not hard local/server-architecture, 14-language, MCP, pricing, or licensing claims; evaluate privacy, scale, and integrations directly.

Free for personal, academic, and non-commercial development under the PolyForm Noncommercial 1.0.0 license. The client-side web application (gitnexus.vercel.app) and local CLI/MCP server run 100% locally with zero cloud subscription fees for non-commercial workflows. Commercial deployments, multi-repo enterprise graphs, team collaboration, and enterprise support require a paid commercial agreement via Akon Labs.Review →

OpenUI

open sourceexplicit relation

OpenUI is an Apache-2.0 design-to-code tool from W&B that turns natural-language interface prompts into live HTML previews and frontend code. Teams can run it locally or with Docker, connect OpenAI, Groq, LiteLLM-compatible providers, or Ollama, and export generated UI toward React, Svelte, Web Components, and related workflows. It fits rapid UI mockups where developers want editable code instead of screenshots.

100% free and open source under the Apache-2.0 license (19k+ GitHub stars, $0 software cost). OpenUI by Weights & Biases generates live, interactive React, Svelte, Vue, and Tailwind CSS components from natural language prompts and screenshots with zero software licensing fees.

Claude CodeAnthropic's agentic CLI coding tool that delegates complex tasks to Claude directly from the terminal. Understands entire codebases via automatic context gathering, edits multiple files, runs shell commands, and manages Git workflows autonomously. Supports CLAUDE.md for persistent project instructions, integrates with VS Code and JetBrains, and uses Claude Opus/Sonnet with extended thinking for complex architectural decisions. Built for terminal-first developers.GhosttyGPU-accelerated terminal emulator written in Zig by Mitchell Hashimoto (HashiCorp co-founder). Native UI rendering on macOS and Linux. Supports ligatures, true color, Kitty graphics protocol, and splits/tabs. Configurable via a simple key-value file with sensible defaults. Open-source with 20K+ GitHub stars and a focus on correctness, speed, and minimal resource usage. Growing as a modern alternative to iTerm2, Alacritty, and WezTerm.Grok BuildGrok Build is xAI's terminal-first coding agent for planning, editing, testing, and reviewing code from a local CLI. The early beta exposes subagent controls, worktree mode, headless JSON output, best-of-N parallel attempts, sandbox profiles, and experimental memory. It fits developers comparing Claude Code, Codex, and Gemini CLI for local agentic workflows with deeper parallel execution.CodexCodex is OpenAI's coding agent for software development across the Codex app, editor, terminal, and cloud tasks. It helps write, review, debug, refactor, and automate code, with ChatGPT plan access for managed surfaces and API-key usage for CLI, SDK, and IDE workflows. The open-source CLI and SDK support local repository work, while cloud features add GitHub review, Slack/Linear integrations, worktrees, skills, MCP, and automations.ScalarScalar is an API documentation platform that generates beautiful, interactive API references from OpenAPI specifications. It provides a modern OpenAPI reference interface with dark mode, request examples in multiple languages, and a built-in API client. Available as open-source packages for any framework or as a hosted platform.ObsidianKnowledge management app based on local Markdown files with powerful linking and graph visualization. Bidirectional links, graph view, canvas for spatial thinking, templates, daily notes, and 5,000+ community plugins. All data is stored as plain .md files with no vendor lock-in. Custom themes, Vim mode, and Dataview support database-like queries. Sync and Publish are paid add-ons; the core app remains free for personal use.Oh My ClaudeCodeOh My ClaudeCode (OMC) is a plugin for Claude Code that adds multi-agent orchestration with 19 specialized agents, smart model routing between Haiku and Opus, and execution modes such as Autopilot, Team, Ralph, Ultrawork, and Deep Interview. It provides lifecycle hooks, a real-time HUD statusline, and source-backed Claude Code workflows that turn one session into a coordinated AI development team.Hermes AgentHermes Agent is an open-source AI agent framework with persistent memory, reusable skills, 40+ tools, cron jobs, and messaging gateways.NotionAll-in-one workspace combining notes, wikis, project management, databases, and documents in a single flexible platform.
