Developer Tools AI Tools

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.

Rust-based PostgreSQL MCP server with 135 tools for Claude Desktop and other MCP-compatible AI tools. Supports stdio, TCP, and HTTP/2 transports, plus quick-start install and setup instructions.

NILScript is an open standard and CLI toolkit for letting AI agents act on real systems through a gated propose → approve → commit → rollback flow. The page shows a live playground, quickstart commands, and benchmark claims around unauthorized writes.

An MCP server for the PostFast API that lets AI tools schedule, manage, and analyze social media posts across major platforms.

MakerChecker is a self-hosted governance layer for AI agents that enforces roles, approvals, and tamper-evident audit logs. The repo shows quickstart commands, a demo flow, and SDK/connectors for TypeScript, Python, and LangChain-style integrations.

ctx is a local-first desktop workbench for coding agents, now open source under GPL-3.0. The page explains that it runs agents in a desktop environment with worktrees, transcripts, artifacts, diff review, container boundaries, and a local merge queue.

A macOS menu bar app that helps users pace Claude Code and Codex usage against weekly and 5-hour quota windows.

Claude for Foundation Models is a Swift package that brings Claude to Apple’s Foundation Models framework on supported beta OS releases. The page includes requirements, install steps, quick-start code, model selection, authentication options, streaming, structured output, and a runnable example reference.

Go-native framework for building, orchestrating, and observing AI agents with native OpenTelemetry, an embedded dashboard, replay, and first-party MCP/A2A support.

An AI API gateway/proxy in Go that sits between coding clients and upstream LLM providers, with request routing, secret redaction, context handling, MCP tool integration, and transparent SSE streaming.

A Rust-based checker that compares a changed function against its prior version on deterministically generated inputs and reports counterexamples when behavior changes. It includes a PR gate via GitHub Actions, CLI usage, signed receipts, and docs for release/signing.
