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.

Harness-as-Code monorepo for shipping agent-built web and mobile products
A versioned `monokit.harness.ts` contract declares app surfaces, shared capabilities, boundaries, agent instructions and the exact commands used to verify changes.
Deployable API (Hono + OpenAPI), web (Next.js), mobile (Expo) and browser extension (Vite) starters share packages instead of duplicating configuration.
Zod contracts connect validation, interactive API docs and typed clients, while transactional state changes add idempotency, audit trails, an outbox and signed webhooks.
Typed tools, permission checks, structured outputs, versioned prompts, deterministic test doubles, evaluations and tracing help you ship AI features that can be tested.
