Capsule is a free, anonymous file transfer tool. Upload any file via curl, the CLI app, the mobile app, or your browser and get a short link and QR code instantly. No login, no account. Files auto-delete after 60 minutes. Optimized for ease-of-use and speed.
My idea was simple, sharing a file:
- Should be FAST and easy in 2026.
- Should be cross-platform.
- Should have multiple interfaces.
- Shouldn't require an account, an email, or sketchy cloud.
Unfortunately nothing provided that, so I took it upon myself to launch Capsule.
It's free, there's no signup, and you can try it in about ten seconds. I'd love to hear what you'd want from a tool like this: longer expiry options, larger files, something else? I'm here all day and will answer everything.

How do you actually keep this free and not run out of storage, and is there a paid tier coming for people who want bigger files or longer retention?

@smailekglvldf Currently, free is sustainable since this is a transfer service, not a storage service. 1h deletions, 100MB max size, and strict enforcement of rate limits allows me it free. Long term, I'll introduce a paid monthly tier for power users allowing larger file sizes & longer retention as hosting requirements scale.
But the core product of Capsule will always remain open & free, as my motivation was to build a fast, no-BS file transfer service.
(I'm also working on a peer-to-peer mode where the server only acts as a connection director, meaning that files of any size move directly between devices without being saved on Capsule's servers.)
