Developer Tools AI Tools

A ~1000-line C workflow runtime where an LLM can modify a DAG during execution using a restricted four-verb grammar, with every change written to an append-only audit log for replay and inspection.

A self-hosted TypeScript harness for building provider-neutral LLM agent systems inside an application or platform, with typed agent and workflow runtime, tool support, state, tracing, and example workspaces.

Herd is a lightweight desktop IDE for coordinating multiple AI coding agents at once. It supports parallel tasks, real-time status monitoring, and works with tools like Claude Code and Codex on Windows, macOS, and Linux.

A local-first, file-based context and memory system for AI coding assistants. It’s designed to persist decisions, tasks, and learnings across sessions so tools can rehydrate project context instead of starting from scratch.

Open-source Rust coding agent with LLM-native code understanding, shell safety, and support for multiple LLM providers with automatic failover.

A tool that converts any URL into markdown optimized for coding agents, with browser, CLI, API, SDK, and agent integration support.

Ragnerock is a research intelligence platform that turns raw sources into queryable, structured data. It supports extraction, analysis, and research workflows across SQL, Excel, PDF, HTML, images, and other sources, with audit trails and deployment into existing infrastructure.

Lightport is a lightweight AI gateway that makes LLM providers OpenAI-compatible. The repo shows supported endpoints, a long provider list, quickstart commands, request examples, and active maintenance signals.

A persistent memory layer for AI agents, built as a standard MCP server with local setup, dashboard, and benchmark claims against other memory tools.

Harness is an open-source app for running a team of AI agents, with support for Claude, browser control, mobile access, and a headless server mode for remote use.

A tiny macOS menu bar utility that keeps your Mac awake for long-running agent work, builds, downloads, and other tasks, even with the lid closed.

AgentRQ is a human-in-the-loop task management platform for AI agents, with MCP-based integrations, real-time notifications, and a Vue/Go stack for collaborative workspace workflows.

A Java framework for building stateful multi-agent workflows on top of Spring AI, with graphs, routing, retries, checkpoints, and shared state.

BugTape is an error-tracking tool built for coding agents, capturing browser errors, failed requests, console output, and replay so an agent can inspect evidence and propose fixes over MCP.

Chemical X is a developer tool for autonomous coding agents that combines AST-based linting, SQLite symbol indexing, silent verification, and an MCP gateway to reduce context noise and catch code decay.

Open-source MCP proxy that blocks agent send/share actions when the destination first appears in untrusted tool output. It uses deterministic rules rather than an LLM and logs every allow/deny decision.

A CLI tool that gives coding agents names from a roster so teams can track who is working on what across Claude Code, Codex, tmux, and cloud sessions.

A semantic CLI for process and port management. It can find, inspect, and stop processes by port, PID, name, path, or folder scope, with explicit support for scripting and coding agents.

A live interactive heat map that tracks AI companies, models, products, people, hardware, and ideas gaining attention across news and developer communities over the last 7 days.

An agent skill that critiques and polishes web UI by inspecting the real page across light/dark and desktop/mobile views, with commands for critique, design, and polish.

Axminster is an AI-augmented software design tool for model-driven engineering. It supports UML 2.5.1 and OCL 2.4, can save models as XMI, and includes an MCP server for sharing designs with LLM-based coding assistants.

A GitHub repository for a Claude Code plugin and helper that shows live per-step progress for long-running shell commands instead of a generic spinner.

An open-source desktop widget for Linux, macOS, and Windows that shows live usage levels for Claude, Codex, and several cloud AI providers. The page includes platform support, install options, behavior details, and packaging notes.

Spotnote is a Vite plugin that lets users click UI elements in a running app, write feedback, and send coding agents a precise file, line, and column target. It also supports MCP, staging builds, and webhook delivery for team workflows.
