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.

Autonomous AI QA agents that verify your web and mobile app on every pull request
Describe a journey or rule in chat and the agent turns it into durable test cases that survive refactors and redesigns.
Every pull request gets a dynamic exploratory pass with preview environments, failure breakdowns, screenshots, console and network logs.
Agents target real browsers and native iOS and Android apps, so coverage reaches beyond the web front end.
Findings flow into Jira and Linear, and agents can be queried over MCP by other coding agents.

#1
SpecialistAn AI-native code editor offering deeper multi-file control, but demands more developer experience than zero-code platforms.

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.
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.
GenAI-native end-to-end QA agent that plans, writes and heals tests in plain language

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.
Turns conversational prompts into published web and mobile apps, but has fewer enterprise-grade scaling templates.

SpecialistGenerates complete websites quickly from text prompts or screenshots, but lacks advanced dynamic database application features.

Ship with confidence: one system of record for manual, automated, and CI tests
