The thing every AI-built one-off lacks is a way to live anywhere but the chat that produced it. Flatpack fixes that. A Flatpack is a single HTML file that opens by double-clicking, runs offline, carries its own data, inline tests, and a small manifest that knows when it should be promoted to something larger. The repo includes templates (calculator, csv-cleaner, checklist, report-builder, decision-tree), worked examples, a checkable schema, and one-file installs for every major coding agent. Built after Baseplate as the companion standard — Baseplate handles things you're shipping for other people; Flatpack handles things you're building for yourself.

Flatpack
A standard for personal AI-built tools. Single file, agent-editable, runs offline.
A checkable standard for personal AI-built tools: one HTML file, runs offline, agent-editable, leaves the chat. Install one config file into your agent (Claude Code, Cursor, Windsurf, Copilot, AGENTS.md) and the agent produces Flatpack-shaped tools by default. The natural companion to Baseplate for things that aren't services but artifacts.
