Developer Tools AI Tools

A Python CLI that packages data science repositories and data-heavy project files into LLM-friendly prompts, with sampling for CSV, SQL, Excel, and notebooks.

A visual editor for React apps that lets you edit UI live and writes the changes back into source files. It runs locally as a proxy/overlay and supports Next.js, Vite, and Create React App.

Open-source terminal coding agent in Rust with LLM-native code understanding, shell safety, multi-provider support, and automatic failover.

A Python framework for building OAuth 2.0 authorization servers for MCP servers, with token storage, PKCE, device flow, introspection, and rate limiting.

A local Rust API gateway that lets tools like Claude Code and OpenAI/Anthropic SDKs talk to OAuth-backed providers through OpenAI- and Anthropic-compatible endpoints.

Desktop AI agent for Excel that works on workbook edits with parallel workflows, reversible changes, and local-first file handling. It supports Claude or OpenAI subscriptions, shows proposed edits for review, and preserves workbook structure like formulas, formatting, charts, and named ranges.

A local, read-only observability dashboard for Claude Code with live event streams, session Kanban, token and cost charts, a 3D tool-call graph, and plugin-based widgets.

Git-native memory for coding agents that stores repo intent, decisions, constraints, and review context before the diff. The repo includes the problem statement, product positioning, install steps, and agent hooks for tools like Claude Code, Cursor, and Codex.

Python package for recording real LLM API responses and replaying them in tests so LLM-driven code can run deterministically without live API calls.

CLI for testing and improving documentation with simulated developer agents. It checks whether docs are clear enough for agents to complete real tasks, reports where they get stuck, and can generate proposed edits.

Open-source multi-modal Claude Code client that runs locally and lets Claude compose across plugins, GUIs, documents, charts, wikis, automations, and messaging bridges.

An open-source VS Code extension that analyzes local AI coding session logs and turns them into dashboards, practice scores, anti-pattern detection, and skill insights.

Open-source infrastructure for running and automating sandboxed coding agents, with local Docker setup, integrations, snapshots, sessions, and automations.

A loadable SQLite extension that adds column-oriented storage and analytics for fast local OLAP-style queries, with benchmark data and build instructions.

A Rust-based hybrid local code search tool for developers and AI agents, with BM25 + semantic retrieval, persistent indexing, tree-sitter symbol search, and MCP/gRPC integrations.

Semble is a local-first code search tool for agents. It offers natural-language search, an MCP server, bash/AGENTS.md integration, and a Python API, with claims of faster indexing and much lower token usage than grep+read.

Patchwork is a Rust CLI for AST-native code refactoring without LLMs. It can find, replace, delete, and insert code by structure instead of regex, with support for Java, Python, JavaScript, TypeScript, and TSX.

Open-source agentic mesh for governing AI agents across enterprise systems, with identity, policy enforcement, audit trails, observability, and Kubernetes-native deployment.

A CLI for the Slack Web API built for coding agents. It exposes Slack methods through a single command format, supports JSON stdin, dry runs, pagination, and discovery commands, and installs via npm.

AI Buddy is a free macOS menu-bar app for screenshots and voice dictation. It lets users capture regions, windows, or full screen, copy instantly to clipboard, and transcribe speech to text using Gemini 3.5 Flash.

Shikigami is a desktop agentic IDE for running multiple coding agents in parallel, each in its own isolated git worktree. It supports Claude Code and OpenAI Codex, keeps sessions resumable, and includes built-in review tools like an editor, terminals, source control, databases, and Docker.

A terminal coding agent for Mac that runs on local models through MLX, edits code, runs tests, and keeps everything on-device.

Open-source AI app builder that turns a prompt into a full-stack Next.js app with hosting, sandboxing, database, auth, GitHub sync, multitenancy, and custom domains. The repo is positioned as a self-hosted alternative to v0, Lovable, Bolt, and Replit, and is meant to be embedded into another SaaS or run standalone.

Harness is an agentic IDE for running coding agents on remote machines over SSH, with one-click backend setup, backend switching, web access, and notifications across machines.
