Open Source & Public Domain
Last updated: May 15, 2026
Express Intent stands on top of a lot of open-source and public-domain work. This page exists so you can see exactly what we use and how it is licensed. We respect open source the same way we respect operators: by being explicit about what came from where.
Public domain content (CC0 1.0)
awesome-chatgpt-prompts
Source of 203 of the prompts on /prompts.html. Curated by @f and contributors on GitHub. The CC0 dedication waives all copyright; no attribution legally required. We credit anyway because the operators who curated this deserve to be named.
MIT-licensed software
Stripe Node SDK
Powers checkout, webhooks, customer dashboard lookups. The stripe npm package is MIT licensed; we use it via Vercel serverless functions.
micro
Helper utilities for the Vercel serverless functions. vercel/micro on GitHub.
CDN-hosted assets
Simple Icons
Brand glyphs in the supported-stack section (Anthropic, Cursor, Windsurf, GitHub Copilot, Warp, Replit, OpenAI) are served from cdn.simpleicons.org. Each glyph remains the trademark of the brand it represents; we display them under nominative-use principles.
Tailwind CSS
Utility-first styling across every page. Currently loaded via the official cdn.tailwindcss.com JIT CDN. Tailwind is a project of Tailwind Labs.
Inline SVG icons we drew ourselves
The Cline, Aider, and Antigravity glyphs in the supported-stack section are custom SVG icons we drew. They are not the official brand logos for those tools. They will be swapped for official logos once those projects publish brand assets we can use under permissive license.
