Very easy to test your idea in Aurelia, Aurelia 2, Inferno, Preact, React, Svelte, and Vue 2.

* Save code in your own GitHub gists, public or private.

* Almost no backend. Backend is only for GitHub OAuth and centralised trace cache for performance.

* Bundler runs purely in browser.

* Built with Aurelia. Less than 10k LOC (js, html, scss) so far. https://github.com/dumberjs/dumber-gist

* Runs on a tiny DigitalOcean $5/mth box. With a CloudFlare free plan to cache static resources.

It's named Dumber Gist, as it runs on a new bundler called dumber https://dumber.js.org (a successor of aurelia-cli built-in bundler).
