Tinykit is an open-source tool for building and deploying tiny web applications. It combines an AI agent, an editor, and a runtime into a single instance, allowing you to host 100+ apps on one server and instantly update them by typing /Tinykit after their domain name.

Overview

Tinykit is in early alpha. It’s best suited for personal utility tools, small business CRUD apps, and internal tools. AI-generated code should be reviewed before handling sensitive data or running in production environments.
Unlike cloud-based builders that separate development from hosting, Tinykit runs the builder and built applications on the same server. The builder (or studio) is always available and can deploy app updates in seconds.

Workflow

  1. Prompt: Describe the application or feature to the AI agent.
  2. Generate: The agent writes code, creates and integrates fields and datbase tables.
  3. Refine: Edit code manually, update content and design from fields, or continue prompting.
  4. Deploy: Push the ‘Deploy’ button, wait 1-2 seconds, enjoy your app.
  5. Repeat: Just to go yourappsdomain.com/tinykit to keep working on it, the studio’s always there.
