Open-source, self-hosted operating system for autonomous AI agents
Run agents against multiple model vendors and swap or route between them without rewriting your agent logic.
Give agents working memory and long-term recall so context survives across sessions instead of resetting each run.
Register your own APIs, scripts and data sources as callable tools that autonomous agents can chain together.
Deploy the whole stack inside your own network or VPS, keeping prompts, memory and tool traffic under your control.
Google's agent-first development platform for building and shipping software with AI agents
A desktop app, a full agentic IDE, a terminal-first CLI, editor extensions, and an SDK let you run Antigravity agents wherever you already work.
Group conversations into Projects and run several local agents at the same time, across multiple workspaces, rather than one at a time.
Agents produce designed artifacts such as plans and comprehensive verification tests so output can be reviewed, not just accepted.
Runs on Google's Gemini model line, including releases such as Gemini 4 Carbon, Gemini 4 Argon, and Gemini 3.8 Flash.

#1
Offers a more mature polished AI-native coding experience, but lacks Google's specific native multi-agent command center ecosystem.

Enables rapid full-stack app building and deployment entirely in the cloud, but offers less granular local agentic control.
Deeply reads entire codebases to execute complex multi-file tasks, though integrated as an IDE plugin rather than standalone suite.
Delivers robust spec-driven engineering and autonomous verification workflows, though configured differently than Google's developer platform.
Cognition's autonomous software engineer that ships real pull requests
Free / Open-sourceBrowser agents and stealth cloud browsers for real web tasks
Free / Open-sourceOpen-source development environment running multiple CLI coding agents in isolated git worktrees, but requires manual setup.
Your always-on AI teammate, hosted and managed for you
Provides a seamless AI-driven IDE workflow with strong multi-file editing, but offers less specialized multi-agent orchestration control.

SpecialistAI-powered terminal and agentic software factory for development teams

High-trust frontier inference, encrypted end to end
