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.

Managed cloud agents for coding, review and background work
Define the trigger, prompt, environment, permissions and compute shape in a config file that lives alongside your code and is reviewed like any other change.
Ellipsis provisions and tears down virtual machines for each session, so agent work never depends on a developer's laptop being open or on hand-rolled runners.
Choose Claude Code or Codex, or mix them, by editing a single configuration block rather than rewriting your automation.
Credentials are minted per session and limited to the repositories you allowed, and source code is deleted together with the sandbox.
