Hey Hacker News! I'd like to showcase Vertex.

Vertex is a browser extension [1] (currently only Chrome) and a web app [2] for saving bookmarks (vertices) along with the source documents.

You can save optional notes along with (almost) everything you can save on Vertex. You can organise your vertices into sets [3] or connect them together as you see fit. Your vertices can hold snapshot(s) of the source. These are self-contained, parseable MHTML documents which stay immutable independently of the source.

Additionally, the Vertex extension will highlight your saved links (along with notes) as you browse.

I built Vertex because of problems I faced — links I cared about silently changed or disappeared, and once my collection got large enough, I lost track of which identical-looking URL I wanted.

Vertex sits between existing archiving systems like ArchiveBox [4] and note-taking applications like Obsidian [5] — snapshots on one side, annotations and a graph on the other. And unlike Wayback Machine's "Save Page Now" [6], the browser extension enables you to capture even login-gated pages.

I've used Haskell for the backend and TypeScript for the frontend. I've run production Haskell for 10+ years, so that's what came most naturally to me.

Future improvements:

- Firefox extension

- Better mobile support

The free tier [7] retains archives for 30 days.

I'd love any feedback, so please give it a spin!
