SaveStack

– Present

16 users · 3,200+ bookmarks synced (still growing)

X/Twitter's bookmark system buries your saved posts with no way to organize, search, or find them again. SaveStack syncs your bookmarks into a personal library you can actually use — with folders, tags, full-text search, and read tracking — updated automatically in the background.

  • Find any saved post instantly through full-text search across content and author names
  • Organize bookmarks into folders and tags instead of scrolling endlessly
  • Read/unread tracking keeps your attention on what's new
  • Library stays current automatically — no manual refresh needed
  • Two-mode sync architecture (fresh + historical workers) — API never blocks user
  • Production: VPS, Nginx, Certbot TLS, Cloudflare DNS, OpenTelemetry → Grafana
