About Cowyo

Cowyo is a shared scratchpad for quick notes, described as a pastebin for minimalists. You open a page, start typing and it saves automatically, then share the URL so others can edit in real time. Visiting the root creates a page with a memorable alliterative name such as calm-cat.

While several people edit a page, each editor's caret appears as a dim gray line. For sensitive notes you can choose a private scratchpad, where the content is encrypted in the browser and the plaintext is never sent to the server. The README warns that lost key links cannot be recovered.

It is written in Go, uses SQLite by default and can use PostgreSQL via a database URL setting. Production options include a public site URL for canonical links and a sitemap, plus optional Umami analytics, AdSense and ads.txt settings. You can try it at cowyo.com or build and run it yourself on port 8001. No licence is declared in the repository metadata.
