Type or paste code. The editor highlights in real time and tracks language, lines and columns.

share code,
not screenshots.
Paste a snippet, pick the language, get a permanent-looking link with real syntax highlighting. The code is the link - nothing is stored on a server.

Your snippet is packed into the URL - share it anywhere.

how it works
no accounts, no uploads, no tracking.
mint
The payload is compressed with DEFLATE and encoded into the URL fragment. No request leaves your machine.
share
Send the link. Anyone who opens it sees a rendered, copyable, downloadable snippet.

snippets you minted on this device. stored locally, never uploaded.
about codebin
a snippet bin that refuses to own your data.
codebin ships in two modes and picks one automatically. With a KV store connected, snippets are saved server-side and you get short links, view counts, comments and ratings - the full reference behaviour. Without one, the payload is compressed and written straight into the URL, so links still work anywhere.
The serverless API is built from plain /api functions with zero npm dependencies: three thin handlers over a KV REST endpoint (Vercel KV or Upstash). Nothing runs on a long-lived server.
what works
- Syntax highlighting for 20+ languages - hand-written tokenizer, no CDN.
- Five syntax themes - neon, amber, ice, rose, mono - switched from the nav and remembered per device.
- Optional link expiry: 1 hour to 90 days, or never. Enforced by storage TTL in server mode, by a signed timestamp in the link in link-only mode.
- Short share links, comments, 5-star ratings, view counts (when storage is connected).
- Raw text endpoint -
curl /s/<id>/raw- and one-click export to a secret GitHub gist. - Copy a snippet as a themed PNG - rendered on a canvas, no backend - ready to paste straight into chat.
- Self-contained URL links as a zero-config fallback.
- Local library of everything you mint on this device.
enabling the backend
- In Vercel: Storage -> create a KV (Upstash Redis) database -> connect it to this project.
- The env vars
KV_REST_API_URL/KV_REST_API_TOKENare injected automatically. - Redeploy.
/api/healththen reportsstorage: trueand short links turn on.
