SharePad

SharePad is a notebook, not a single paste. You get many markdown pages behind one slug (/n/kitchen-reno), a secret edit URL (/e/{token}), and no account. Creating a notebook mints a 32-byte edit token; only the SHA-256 lives in Postgres. The browser keeps the token in localStorage. Lose the token and there is no recovery by design.

Defaults: unlisted, expires in 10 days (override to a year or never). Optional password, read-only freeze, burn-after-read, open editing for anyone with the view link, last-ten draft history per page, PDF/print layout, whole-notebook markdown export, comments without an account. Images compress to WebP in the client and land in Cloudflare R2.

Varshith Hegde's README lists the stack as Next.js 16 (App Router, Turbopack), Supabase Postgres, Tailwind 4, react-markdown. A GitHub Action pings /api/ping every three days so the free-tier Supabase project does not pause. sharepad.in 301s to www.sharepad.in. Both resolved on this check.

List it as the "send a structured note without spinning up a wiki" tool. The interesting design choice is token ownership instead of users.
