Agents

OpenClaw

Other (see repo)

Open-source general-purpose personal agent that runs on your own machine and lives in your messaging apps — with tools, persistent memory, and automations wherever you already talk.

hermes-agent

MIT

Nous Research's open-source personal agent — persistent memory, tool use, and multi-channel deployment — among the most heavily used open agents by independent inference-volume measures.

langchain

MIT

A widely adopted framework for building LLM applications and agents, with composable abstractions for prompts, memory, tool calling, and retrieval across many model providers.

browser-use

MIT

Lets AI agents control a real web browser to navigate sites and complete tasks, turning natural-language goals into automated clicks, form fills, and data extraction.

TradingAgents

Apache-2.0

A multi-agent framework for LLM-driven financial trading research: specialist analyst agents for fundamentals, sentiment, news and technicals feed a bull-versus-bear debate, then risk management and a trader agent synthesise a decision. Model providers and market-data vendors are pluggable.

langgraph

MIT

A library from the LangChain team for building stateful, multi-step agent workflows as graphs, with durable execution, branching, and human-in-the-loop control.

crewAI

MIT

A framework for orchestrating teams of role-playing autonomous agents that collaborate on complex tasks, each with its own goal, tools, and backstory.

AutoGPT

Other (see repo)

One of the earliest autonomous GPT agents, now a platform for building, deploying, and running AI agents that chain tasks toward a goal with minimal human input.

autogen

CC-BY-4.0

Microsoft's framework for building multi-agent AI applications, where several conversable agents coordinate, call tools, and hand off work to solve tasks together.

agno

Apache-2.0

A Python framework and platform for building, running, and managing AI agents, with built-in memory, tools, and multi-agent teams.

OpenAI Agents SDK

MIT

OpenAI's lightweight Python framework for multi-agent workflows, with handoffs between agents, guardrails, and built-in tracing.

nanobot

MIT

Ultra-lightweight self-hosted personal agent framework in Python from HKUDS, with a web UI, tools, memory, MCP support, and multi-agent workflows.

cua

MIT

Open-source infrastructure for computer-use agents: sandboxes, SDKs, and benchmarks for AI that controls full macOS, Linux, and Windows desktops.

pydantic-ai

MIT

An agent framework from the Pydantic team that brings type-safe, structured outputs and validation to LLM applications and tool calling.

deer-flow

MIT

An open-source long-horizon agent harness from ByteDance that researches, writes code, and produces content using sandboxes, memory, tools, and subagents.

Vibe-Trading

MIT

Personal trading agent framework from HKUDS: LLM-driven market analysis, strategy backtesting, and automated execution under one agent loop.

anything-llm

MIT

An all-in-one, self-hostable desktop and web app for running local-first AI agents over your own documents, with RAG, tools, and multi-user support.

letta

Apache-2.0

A platform for building stateful agents with long-term memory that persists across sessions, letting agents learn and improve over time (formerly MemGPT).

goose

Apache-2.0

Open-source agent that runs on your own machine as a desktop app or terminal CLI and does real work rather than suggesting it — installing dependencies, editing and testing code, and driving external systems through MCP extensions, with any model you point it at. Built at Block and now governed by the Linux Foundation's Agentic AI Foundation.

cherry-studio

AGPL-3.0

Cross-platform AI studio bundling chat, autonomous agents, and hundreds of ready-made assistants over unified access to frontier and local models.

CowAgent

MIT

Agent harness grown out of the chatgpt-on-wechat project: plans tasks, runs tools and skills, and carries persistent memory across many models and chat platforms.

CopilotKit

MIT

Frontend framework for building agent-native applications in React, Angular, and beyond — generative UI, in-app copilots, and the AG-UI protocol connecting interfaces to any agent backend.

Mastra

Other (see repo)

A TypeScript framework for building AI applications and agents, with workflows, evals, memory, and MCP support in one toolkit.

activepieces

Other (see repo)

Open-source workflow automation platform where AI agents, MCP servers, and hundreds of prebuilt integration pieces compose into automated business flows that agents can drive directly.

Vercel AI SDK

Other (see repo)

Vercel's TypeScript toolkit for building AI applications: a unified interface across model providers, plus streaming, tool calling, and generative UI for React, Svelte, and Vue.

SuperAGI

MIT

A developer-first open-source framework for building, running, and managing autonomous AI agents, with a GUI, tool integrations, and concurrent agent support.

Cloudflare Agents

MIT

Cloudflare's SDK for building and deploying agents on its edge platform, using Durable Objects for state and workflows that survive restarts.
