Build working apps, websites, and AI agents by describing them
Describe an idea and get a working app with database, authentication, payments, and hosting already wired up — no server or infrastructure setup.
Generates complete websites with layout, copy, and design, plus built-in SEO tools and custom domain support, ready to publish in one click.
Create 24/7 AI agents that connect to your tools, take real actions, manage data, and automate recurring workflows autonomously.
Connects to Google Calendar, Gmail, Slack, Notion, HubSpot, Salesforce, and more, with API access for anything else you use.

The autonomous control plane for your AI coding agents
Sessions are grouped into Needs you, Working, Waiting, In review, and Done so you immediately see which agent is blocked on your decision.
Agents review their project on a schedule in hidden read-only sessions, stay quiet when nothing changed, and report back in a single card.
A Loop pairs a goal with a way to verify it and a stop; runs are iteration-capped and end as done, no-op, blocked, failed, exhausted, stalled, or canceled.
Put agent work on a cron-like schedule, a runtime trigger, or a signed webhook, with every run recorded automatically.
Powerful full-stack app generation from natural language, but offers more polished UI components and smoother deployment flows.

The AI coding agent for building ambitious software
Google's agent-first development platform for building and shipping software with AI agents

Provides a robust cloud development environment with agentic coding, but requires more manual coding oversight than pure no-code.
Converts conversational prompts into hosted applications, though with slightly less advanced UI design customizability.
Free / Open-sourceOpen-source workflow automation built for AI agents and technical teams
Generates full-stack web apps directly in the browser, though sometimes less structured for enterprise backend scaling.
SpecialistExcels at generating high-quality front-end user interfaces, but requires additional setup for complete full-stack backend integration.

The coding agent that learns your coding taste

Free / Open-sourceOpen-source control plane for orchestrating coding agents

Instantly builds fully functional web apps with integrated databases and payments, but features fewer advanced customization controls.

SpecialistTransforms spreadsheets into interactive business apps easily, but lacks the raw code generation flexibility of full-stack AI builders.
