Build sovereign apps and websites by chatting with AI
Describe an app, website, or internal tool in natural language and generate a working version you can refine through chat.
Ask plain-language questions and Caffeine reads across all the apps you have built to return an answer instead of one dashboard at a time.
Apps run on the Internet Computer, and code and data are presented as exportable so you can move your software to hosting of your choice.
Deploy on Caffeine's hosting, your own cloud, or machines selected for your security and location requirements.
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.

#1Generates full-stack web applications from natural language prompts with interactive previews and responsive interfaces.

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

Transforms natural language descriptions into functional applications, websites, and autonomous AI agents.

Enables rapid full-stack app building and deployment entirely in the cloud, but offers less granular local agentic control.
Converts conversational prompts into fully functional, hosted web and mobile software applications quickly.
Deeply reads entire codebases to execute complex multi-file tasks, though integrated as an IDE plugin rather than standalone suite.

SpecialistCombines a professional visual web design canvas with an AI design agent for sites.
Delivers robust spec-driven engineering and autonomous verification workflows, though configured differently than Google's developer platform.
Builds and runs full-stack web applications and prototypes directly in the browser from prompts.
Converts natural language prompts into working front-end components and full-stack web applications.
Cognition's autonomous software engineer that ships real pull requests
