NaHAL

HAL navigator · version 2.1.0

Point it at a HAL endpoint and walk the API: follow links, expand URI templates, inspect embedded resources and build requests. Two builds of the same UI — pick either.

JavaScript build → Runs in any current browser. The compatible choice. WebAssembly build → Smaller and faster. Needs a WasmGC browser: Chrome/Edge 119+, Firefox 120+, Safari 18.2+.

Something to navigate

Two static HAL entry points are hosted here, both describing The Color API. Paste one into the address bar of either build above:

https://c06a.github.io/NaHAL/api-expanded.json Absolute hrefs — follows straight away in this plugin-free demo.
https://c06a.github.io/NaHAL/api.json The same document with color: prefixes against an uppercase CURIE collection. Following those links needs a CURIE-rewriting plugin, so here they resolve only as far as the prefix — useful for seeing what a plugin has to do.

This demo is served over HTTPS, so it can only reach APIs that are themselves HTTPS and send Access-Control-Allow-Origin for this origin. For a HAL server on your own machine or network, download the browser bundle from the release page and serve it over http://localhost instead — same app, no mixed-content or CORS limits.
