LinkRing is built with a bunch of great open source tools and inspired by some cool projects in the ATProto ecosystem. Here's the full list.

The Stack

Bun — JavaScript runtime. Fast, everything is included, and I have never had an issue.
Hono — Lightweight web framework. Small, fast, works great with Bun.
Open Props — CSS custom properties for consistent design tokens. It's what I start every site with now, makes it really easy to just have easy access to things like HSL colors.
PostgreSQL — The database. Was going to use sqlite but wanted to deploy to Fly.io.
postgres.js — PostgreSQL client for Node/Bun. Simple, fast, not an ORM.

ATProto — The protocol that makes all of this possible.
@atproto/oauth-client-node — OAuth client for ATProto. Handles all the "DPoP" and "JWT" complexity.
@atproto/api — API client for talking to PDSes.
Jetstream — Simplified firehose for ATProto events. Powers the Explore page (because it queries the same network!)

These projects showed what's possible on ATProto and helped shape how LinkRing works:

Linkat — The first (?) link-in-bio on ATProto. Proved the concept works.
Leaflet — Long-form publishing on ATProto. Beautiful execution of storing content on your PDS. Even if it's funky blocks format.
Frontpage — Link aggregator, like if Hacker News ran on ATProto. Cool use of custom lexicons.
Smoke Signal — Events and RSVPs on ATProto. Another great example of non-social-media uses for the protocol.

If you want to build your own ATProto app, these helped me:

Beyond the Statusphere: OAuth TLDR — Bailey Townsend's guide to ATProto OAuth.
ATProto OAuth Spec — The official spec.
Lexicon Guide — How to design your data schemas.
awesome-lexicons — Collection of third-party lexicons. Great for seeing what others have built.
PDSLS — Browse any PDS. Invaluable for debugging.

Thanks to everyone who built these tools. Standing on the shoulders of giants, etc.
