Simple temporary live collaboration notepad with websockets and FastAPI — pads expire automatically after a configurable retention period.

Features

• real-time WebSocket collaboration with cursor preservation across remote edits
• per-pad password protection (PBKDF2-SHA256), with a built-in password generator in the UI
• ?pw=… on a pad URL locks it with that password if it is not protected yet, and unlocks it if it is — so /{pad_id}/?pw=s3cret is a one-step create-and-lock link
• optional syntax highlighting (24 languages) from a per-pad dropdown, shared with everyone on the pad; highlight.js is vendored locally and loaded lazily, so a plain pad fetches nothing
• line numbers; Tab inserts 4 spaces
• click a line number to "ping" it — that line flashes for five seconds for everyone on the pad
• dark / light mode (auto-detects system preference, manual toggle)
• copy-to-clipboard and "new pad" buttons, live peer count in the header

Endpoints

• custom pad path {pad_id} (1–64 chars, [a-zA-Z0-9_-]); auto-generated IDs are 8-char [a-z0-9]
• POST / — create a pad from the request body (curl-friendly)
• GET /{pad_id}/ — editor page (?pw=… sets the password on an unprotected pad, unlocks a protected one)
• GET /{pad_id}/raw — raw text (auth via ?pw=… for protected pads)
• GET /system/info — this page
• GET /health — JSON health check (200 ok / 503 degraded)
• GET /system/metrics — Prometheus metrics, disabled by default
• WebSocket /ws/{pad_id} — live collaboration
