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.

Graphify is a free, open-source tool under the MIT license that converts codebases, documentation, and media into queryable knowledge graphs for AI coding agents.

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 under the MIT License; runs locally with developer-owned API keys across Grok CLI, Claude Code, and OpenAI Codex.

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.

codebase-memory-mcp is a free and open-source MIT-licensed standalone C binary. It operates 100% locally on the developer's machine using Tree-sitter and SQLite, incurring no recurring software fees or external API charges.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.

GitNexus is source-available under the PolyForm Noncommercial 1.0.0 license, offering free usage for personal and educational exploration. Commercial usage requires a commercial license from 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.

OpenUI by Weights & Biases is free and open-source under the Apache-2.0 license. Developers can run the UI generator locally using Docker or Python, supplying their own OpenAI, Anthropic, Groq, or local Ollama endpoints.

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.AmpAmp is a multi-model coding agent for terminal, web, macOS/iOS, and IDE-connected workflows. Vendor docs describe the same agent and threads across surfaces, with remote Orbs, local Runners, Dial modes (low / medium / high / ultra), shared threads, MCP, plugins, and BYOK / linked ChatGPT subscriptions. Pricing spans a free Hobby tier, optional Megawatt ($20/mo) and Gigawatt ($200/mo) Individual plans, no-extra-charge Teams workspaces, pay-as-you-go credits, and Enterprise.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.ripgrepUltra-fast recursive text search tool written in Rust that respects .gitignore rules automatically. Searches directories significantly faster than grep with smart defaults like line numbers, syntax highlighting, and compressed file support. The de facto replacement for grep among developers, combining the speed of Rust with sensible defaults that eliminate the need for complex command-line flags.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.FastGPTFastGPT is an open-source no-code AI knowledge base platform with 27,000+ GitHub stars and 500,000+ users worldwide.
