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.

No-code AI champions that take over your team's recurring engineering operations
Ready-made agents such as Code Reviewer, Scrum Master, Support Hero, Incident Leader and Release Manager cover the responsibilities engineering teams repeat most.
Adapt champions to your own processes with flexible building blocks instead of writing automation code from scratch.
Connect the everyday tools your team already runs and let champions read and act inside them.
Kypso states it does not store raw data from your connected tools and works through permissions granted by the original apps.

Converts conversational prompts into hosted applications, though with slightly less advanced UI design customizability.

Automate work across thousands of apps — no code required
Free / Open-sourceOpen-source workflow automation built for AI agents and technical teams
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.
No-code builder for custom AI agents and workflows
GenAI-native end-to-end QA agent that plans, writes and heals tests in plain language
