An open-source agentic browser harness that lets existing agent CLIs control your logged-in browser through a side panel and optional MCP server.

A lightweight Rust terminal notes app with SQLite full-text search and an MCP server so Claude can read, create, and update notes.

MCP server and desktop app for editing Excel files with AI agents, real-time calculation, diff review, and surgical saves that aim to preserve workbook contents.

A browser agent that runs goal-driven workflows, verifies results in the browser and backend, and can hand off to an LLM only when deeper reasoning is needed.

A native macOS app that visualizes Claude Code runs as a city of robot-staffed offices, mapping projects, teams, and CLI events into an interactive workspace.

Windows UI Automation backend for computer-use agents, extending arc-cua with a JEV-driven decision loop for desktop tasks on Windows.

Cockpit is a free local macOS app for managing Claude Code and Codex sessions in one window. It shows which sessions need attention, lets you start new runs, organize many sessions, review transcripts, and inspect file/version history without sending data off your Mac.

Recurse is a serverless harness for building specialist agents and deploying them as tools, MCPs, or bots. The page shows a concrete manifest-based workflow, validation of inputs and outputs, and examples for tasks like level design and RNA sequence design.

Maxxwell is a workspace for managing multiple coding agents at once. It tracks agent progress, highlights stuck work, and surfaces where time is being spent so you can intervene only when needed.

Open-source Python framework for building multi-agent LLM apps that can run on local models through Ollama or on hosted APIs like OpenAI, Anthropic, and OpenRouter. The repo highlights built-in plugins, workflow orchestration, agent serving over HTTP, and guardrails for tool use.

A CLI coding agent designed to make small local models more reliable through sampling, verification, and targeted repair. It supports interactive and one-shot workflows and can use local or remote providers.

Open-source mission-control desktop app for Claude Code that turns projects into a pixel-art campus, with live agent status, task orchestration, spending visibility, and permissioned chat.

Agenttik is a local workspace for running AI coding sessions across multiple projects. It supports Claude Code, Codex, GitHub Copilot, and OpenCode Go, with desktop and web usage, project workspaces, recurring tasks, remote connections, and local/private profiles.

A Swift package for running JavaScript LLM agents inside a Swift app using the XS engine, with snapshot/restore support, resident agents, and confined tool access.

An open-source C compiler written in Java, with a preprocessor, parser, semantic analysis, TAC lowering, a VM, and an interactive C shell. The repo also includes an x86-64 assembler, build and test instructions, and concrete proof points like passing Lua and curl test suites.

A local MCP server plugin for Astah Professional that lets AI agents create, explain, and convert UML models and diagrams.

A Claude Code status line that shows session size, next-turn cost, and remaining budget before you type.

Radia is an agent coordination layer for independently deployed agents, with immutable records, lease-based claims, permissions, and provenance tracking for who acted and what produced each result.

Openvurp is a local-first multi-agent workspace where agents have jobs, tools, memory, and can consult each other instead of answering in isolation. The repo shows browser, CLI, and Docker setup, plus concrete workflows for running commands, writing files, and using multiple channels.

A production-ready Rails SaaS starter designed to give coding agents strong architectural context, with authentication, billing, authorization, Hotwire, Tailwind, Kamal, and repo-based guidance for extending the app consistently.

Blume Sidecar is a desktop companion for managing coding agents across tools like Cursor, Claude Code, and Codex. It tracks agent activity, monitors rules and hidden files, shows usage limits, and suggests fixes when instructions drift from chat context.

1endpoint is an AI model gateway that exposes multiple models through one compatible API with usage-based pricing and transparent per-token rates. The page highlights request formats, model pricing, cache-aware billing, and live traffic stats.

ModelPeer is an open-source tool for cross-model peer review in coding workflows. It lets Claude Code, Codex CLI, and Gemini CLI review one another as read-only engineering peers, with commands for consultation, diff review, setup, updates, and safety controls.

Chrome extension that captures a fixed screen region, runs offline OCR with bundled Tesseract, and exports page-by-page text for use with LLMs or search.
