Purl

Save anything. Keep it in one place.

Live preview: https://purl.nublson.com

Purl is a read-it-later app — a home for your "pearls". You paste URLs: web pages, PDFs, YouTube videos, and audio. Purl resolves each item's metadata (title, favicon, description, thumbnail) and keeps everything in one place, available from the app, a REST API, and an MCP server.

Purl is free, with one limit: each account can save up to 1,000 links (MAXSAVEDLINKS in src/lib/limits.ts).

The product goal: one place to stash material you care about.

Implemented today

  • Marketing site — Landing page (hero with a live preview), docs for the REST API and MCP server, privacy and terms.
  • Authentication — Email/password (and related flows) via Better Auth; optional email verification through Resend.
  • Save & organize
  • Add items by URL with automatic content-type detection (web, PDF, YouTube, audio).
  • Links grouped by relative time (e.g. Today, This Week, Last Month).
  • Preview metadata (title, description, favicon, thumbnail where available).
  • Hardened outbound fetch — Server-side safeFetch with optional proxy/DNS controls (see AGENTS.md). An egress proxy can be configured via SAFEOUTBOUNDHTTP_PROXY.
  • Realtime list sync — Supabase Realtime so saves and updates propagate across tabs/devices quickly.
  • Link actions — Open original, copy URL, edit metadata, delete.
  • REST API & MCP — /api/v1 and an MCP server (savelink, listsaveditems, getlink) with API-key or OAuth auth.
  • Operational extras — Optional Upstash-backed API rate limiting, optional Sentry, Vitest coverage for critical paths.
  • PWA (installable app) — Web App Manifest plus a Serwist service worker (src/app/sw.ts) that builds to public/sw.js (generated on pnpm build, gitignored). Enables Install in Chrome/Edge and similar where the platform supports it, with runtime caching via Serwist's Next.js defaults and a static offline shell at /~offline. Serwist is disabled in pnpm dev to avoid service-worker cache surprises during development — use pnpm build && pnpm start (or your production URL) to exercise installability and the SW.

Save flow

Saving a link is fully synchronous — there is no background processing.

  1. Input — POST /api/links with a URL (also /api/v1/links and the MCP save_link tool).
  2. Classify & decorate — Server-side detectContentType (SSRF-safe HEAD / sniff) plus scrapeLinkMetadata (Open Graph HTML, PDF Content-Disposition / size, YouTube oEmbed). Saving an existing URL again refreshes its metadata and moves it to the top.
  3. Persist — A Link row with title, favicon, thumbnail, domain, and contentType (WEB, PDF, YOUTUBE, or AUDIO).
  4. Sync — broadcastLinksChanged notifies other tabs/devices via Supabase Realtime.

Not implemented yet

These are called out explicitly because the repo is going public:

  • Settings breadth — Settings include account deletion; broader account preferences (profile edits, password change, notification settings, etc.) are not implemented yet.

Marketing vs. product: The landing page copy mentions ideas such as collections and a weekly digest. Those are not built in the current schema or app — treat them as roadmap, not shipped features.
