Rustybin

Privacy-first pastebin with client-side E2EE and zero-knowledge.

About Rustybin

I couldn't find a pastebin service that had the feature set I wanted. One such feature is storing multiple files under a single link, with syntax highlighting and markdown rendering. Useful for my C++ source and header files, and maybe a README written in markdown.

So I built Rustybin! It primarily focuses on privacy but has some useful features I think other developers might like.

  • Client-side AES-GCM encryption; server never sees contents

  • Zero-knowledge: Decryption keys are stored in the URL fragment (#), never transmitted

  • Automatic syntax highlighting for 30+ languages

  • Workspaces for multiple pastes under one link

  • Dark UI

  • Burn-after-read and set expiration

  • Share/edit links to update paste content; useful for collaborators

  • RESTful API

You can try it at https://rustyb.in or https://rustybin.net

Feedback on security, UX quirks, or missing features is highly appreciated!
