Agent Zero

Transparent AI agent framework with 100+ skills and real-time visibility

Agent Zero is an open-source general-purpose AI agent framework with 16,700+ GitHub stars that uses the computer itself as a tool. Unlike structured orchestration frameworks, it provides full transparency where every thought, action, and tool call is visible and editable in real time, supporting 100+ extensible skills.

About Agent Zero

Agent Zero takes a radically transparent approach to autonomous AI agents. Every reasoning step, tool invocation, and decision point is visible to the user in real time, allowing developers to observe, understand, and intervene in agent behavior as it unfolds. This transparency-first design philosophy contrasts with more opaque agent systems where internal reasoning is hidden behind API calls, making Agent Zero particularly valuable for debugging, learning, and building trust in agent capabilities.

The framework provides over 100 built-in skills covering file system operations, web browsing, code execution, system administration, and more. Skills are modular and extensible, allowing developers to add custom capabilities without modifying the core agent loop. The architecture supports Anthropic SKILL.md standard, making it interoperable with Claude Code, Codex, and Cursor ecosystems. This positions Agent Zero as a unifying layer that can leverage skills from multiple agent ecosystems.

With 16,700+ GitHub stars and an active community of 288 watchers and 3,300+ forks, Agent Zero has demonstrated strong developer interest in transparent agent architectures. The MIT license and Python implementation make it accessible for experimentation and production use. The framework supports multiple LLM backends and provides a web interface for managing agent sessions, viewing execution history, and configuring skill availability for different use cases.

Google's official Agent Development Kit for building AI agents in Go

adk-go is Google's official Agent Development Kit for the Go programming language, providing the tools and abstractions needed to build production AI agents. It supports tool calling, multi-turn conversations, structured outputs, and integration with Google's Gemini models. With 7,300 GitHub stars and Apache 2.0 license, it brings first-class AI agent development capabilities to the Go ecosystem.

Open Source

The 5MB open-source agent daemon that hides nothing

CrabTalk is a lightweight five-megabyte daemon that streams every AI agent event to your client in real time including text deltas, tool calls, and thinking steps. It provides complete transparency into agent operations with one-curl installation and bring-your-own-model support. Designed as the observable alternative to opaque agent runtimes where you cannot see what the AI is actually doing.

Open Source

Open-source sandboxes and SDKs for AI agents that control desktops

Open-source computer-use infrastructure for agents that need to drive desktop environments in the background. CUA includes Cua Driver, Sandbox, Run, Bench, and Verified Data across Linux, Windows, macOS, and Android, with MCP and CLI surfaces for screenshots, accessibility trees, keyboard/mouse actions, shell commands, task evaluation, and fleet execution.
