scrummy

A task board that remembers every change. Move a card, reassign an owner or leave a comment, and the task keeps a timeline of who did what and when — for teams where not everyone is a developer.

Live demo: scrummy-one.vercel.app → Try the demo — no sign-up. Each visitor gets a private board with a teammate and some history, built through the same code paths as real use.

What it does

• Board with To do / In progress / Done, drag-and-drop ordering and filters.
• Per-task timeline: every status change, reassignment, priority, due date, label edit and comment is a TaskEvent, so a task's history is its own audit log.
• Teams: invite links (regenerable), owner/member roles, subtasks, comments you can edit or delete.
• Offline-first PWA (Serwist): edits made offline go into an outbox and replay on reconnect; conflicting edits resolve last-writer-wins by client timestamp, and the losing edit still shows in the timeline.
• Auth written by hand: scrypt password hashes, hashed session tokens in an httpOnly cookie, Google sign-in, per-IP rate limits, and one error message for every failed login so emails can't be probed.
