Developer Tools AI Agents
Compare the best open-source AI agents for developer tools. SDKs, CLIs and frameworks for building with AI. Ranked by GitHub stars, with install commands, what each one can touch and scan reports where available.
KADATH
Evolutionary multi-agent runtime that breeds, evaluates, and improves autonomous agents across reproducible epochs to converge on optimization of a goal.
Agents Aea
A framework for autonomous economic agent (AEA) development
NeMo Relay
Multi-language agent runtime and library for execution scope management, lifecycle events, and middleware on tool and LLM calls.
Markus
The all-in-one AI workforce platform, to build AI agent teams. You are the boss.
Iterative Development
Iterative development methodology plugin for Claude Code — extracts requirements, defines walking skeleton, loops through audited sprints autonomously
Collaborative Gym
Framework and toolkits for building and evaluating collaborative agents that can work together with humans.
GAAI Framework
Turns AI coding tools into reliable software delivery systems. Drop a .gaai/ folder into any project — Discovery defines what to build, Delivery executes autonomously until criteria pass. Works with Claude Code, Codex CLI, Gemini CLI, Cursor, and more. No SDK. No package. Markdown + YAML + bash.
Gru AI
Autonomous AI agent team for one-man companies. Context engineering + harness engineering drive a pipeline that brainstorms, builds, reviews, and ships.
Jobsmith
針對台灣求職市場的開源多代理 AI 求職 co-pilot:自動找職缺、履歷健檢、一鍵產生客製投遞包(履歷・求職信・面試準備・公司情報)與模擬面試。本機 Claude Code/Codex CLI 免 API key,也可自備金鑰接 OpenAI 相容模型。
Nexusdesk
Open-source, self-hosted, extensible Agent platform built around ReAct and Harness engineering, with AI customer support as its first complete reference application.
Aibitat
Multi-Agent Conversation Framework in TypeScript
Loop Js
A loop engineering framework — state a Goal; Rounds run until a skeptical, read-only Verify agent settles it.
Goal Flow
Graph-Orchestrated Agent Loop — a production-grade framework on LangGraph. Combine workflow graphs and agent loops, transpile Dify DSL to runnable code, swap wire protocols (Dify/OpenAI).
Loopgain
An open-source cost controller for AI agent loops — stops a loop when it's actually converged and rolls back before it degrades, instead of running to a fixed max_iterations cap. Real-time loop-gain (Aβ) bands + best-so-far rollback. Adapters for LangGraph, CrewAI, AutoGen, LangChain, OpenAI Agents, and Claude Agent SDK; raw API for custom stacks.
OpenHarness
Reliability harness for long-running OpenClaw agents: persistent state, strict task contracts, scheduled execution, and external validation.
Nagato AI
Simple cross-LLM AI Agent library
AssemblyZero
Parameterized multi-agent orchestration framework for Claude Code and Gemini
Dsh Sieve
dsh-sieve: context engineering & token optimization plugin for DeepSeek Harness (DSH) — tool output filtering, context pruning, progressive skill disclosure. 36% smaller payload in offline replay. DSH 上下文管理与 token 优化节省插件。
Ebiose
The self-evolving AI factory: an open-source framework that builds, evaluates and evolves AI agents for your task. An Inria spin-off.
Armada
Loop engineering for software development. Turn any repository into a self-organizing AI engineering team — 8 specialists, contract-driven, evidence-gated, parallel feature voyages.
A2a Adapter
Open Source A2A Protocol Adapter SDK for Different Agent Frameworks and Harnesses
Cockpit Agent Sim
Agent framework for smart-cockpit apps · 面向智能座舱业务的 Agent 框架:零后端、权限分级、确认流、卡片编排、快慢双层、真实三方集成,加能力=加数据不加代码
Nerve
Self-hosted AI agent runtime — personal assistants, autonomous workers, and everything in between. Built on the Claude Agent SDK.
Obsidian Steward
A vault-specific agent equipped with agentic capacity, fast search, flexible commands, vault management, and terminals to "jump" into other CLI agents, such as Claude, Gemini, etc.
