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.

Local-first workspace that turns your AI coding agents into a coordinated crew
A default team of Partner, Engineer, Product Lead and Designer works in parallel on a shared project context and hands off work with short briefs.
Bind Opus to planning, GPT-5.x to codegen and a local model to review, then swap models per task across seven providers and many runtimes.
Skills and per-project memories persist as plain files and a background Partner proposes new ones from real run evidence for your approval.
State lives in ~/.crew44, the daemon binds to 127.0.0.1, and there is no cloud account, subscription, telemetry or remote inference.
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.
A spec-driven AI IDE and agent platform that plans, builds, reviews, and verifies real engineering work.
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-sourceRun many coding agents in parallel, each in its own worktree

Instantly builds fully functional web apps with integrated databases and payments, but features fewer advanced customization controls.
SpecialistAn AI IDE and coding agent that works on your project, not just your cursor
