Developer Tools AI Tools

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.

An MCP server that lets Claude, ChatGPT, Cursor, and other MCP clients search first-party AI engineering jobs, inspect full postings, and query board stats without leaving the chat.

A macOS CLI for Firebase Crashlytics that helps AI coding agents and developers search production crashes, inspect stack traces, and measure crash impact from the terminal.

An iPhone and iPad SSH terminal built for monitoring and responding to AI agents, with sealed agent notifications, Secure Enclave keys, and live panes for workspaces and tabs.

A macOS CLI and skill for Claude Code/Codex that lets AI agents draw arrows, boxes, and text on the screen to guide a human during prompts, approvals, and demos.

Chelis is a numerical computing language for code that agents can write and people supervise. It adds typed tensors, shape and precision checks, proof checking, and MCP tools for agent workflows.

An open-source iPad app that turns handwritten notes into AI answers by detecting triple underlines or circles and responding in a handwriting style.
