Keep a multi-platform product on a shared TypeScript foundation

What is MonoKit?

A product that spans a website, a mobile app and an API needs more than three independent starter projects. MonoKit organizes those parts into a TypeScript monorepo so developers can work from a shared foundation. Its official stack brings together application frameworks and supporting infrastructure, with particular attention to durable work, AI features and the checks that help a growing codebase stay understandable.

Connect the application layers

The public description includes Next.js for web, Expo for mobile and Hono with OpenAPI for APIs. Shared packages and environment loading help coordinate the repository. Durable workflows, AI evaluation and cost tracking address concerns that appear when an AI feature becomes part of a product rather than a standalone experiment. Agent context and executable checks support the development process around that code.

Evaluate the repository as a working system

Trace one feature across the web interface, API and persistence layer before extending the starter. Check where configuration belongs, how changes are validated and which packages are shared. For AI features, define useful evaluation examples and monitor costs from the beginning. A coherent monorepo can reduce duplicated infrastructure, but its value depends on whether the team understands its conventions.

Features to explore

• Shared TypeScript monorepo
• Web, mobile and API foundations
• Durable workflow support
• AI evaluation and cost tooling

Who is MonoKit for?

Developers building a product across web and mobile who want shared application structure and are comfortable adopting repository conventions rather than assembling every component separately.

Before you get started

Review the license, dependencies and deployment requirements. Shared code can also spread mistakes across applications, so test permissions, configuration and platform-specific behavior carefully.
