URL explainer
Why does this URL look weird?
The long part after #agent-render= is the artifact itself, compressed into the URL fragment so a static host can show it without receiving the content in the page request.
The shape
https://agent-render.com/#agent-render=v1.arx.1.<compressed-payload>
Everything before # loads the app. Everything after # stays in the browser and tells the app what to render.
v1
The payload format version. It lets old and new links fail clearly instead of guessing.
arx
The compression method. It uses an agent-render dictionary, Brotli compression, and URL-safe text encoding to keep rich artifacts linkable.
Privacy
The static host does not receive fragment contents during the page request. The link is still not a secret: browser history, copied URLs, screenshots, logs from tools that inspect the full URL, and future client-side analytics can expose it.
In 30 seconds
A normal page URL asks the server for a route. An agent-render URL also carries a compressed artifact after the hash mark. Browsers do not send that hash to the server in the initial request, so the static app loads first and then decodes the artifact locally.
The weird-looking text is a transport format, not a tracking code. Shorter codecs like deflate and arx make markdown, code, diffs, CSV, and JSON fit into shareable links.
Use fragment links for quick static sharing. Use the optional self-hosted UUID mode when the payload is too large, the target chat app mangles long links, or you need a short URL and accept server-side storage.
