What is Pubky?
An open protocol for censorship-resistant apps.
Who is Pubky best for?
Pubky is best for developers building apps where people own their identity and data.
Developers of user-owned apps
SDKs for JavaScript, React Native and Rust cover key-based sign-in, file storage on a homeserver and event streams, and an app template gets you started.
People leaving closed social networks
The pubky.app social app lets you post, tag and follow with an identity based on your own keys, which you can take to other Pubky apps.
Self-hosters
Anyone can run their own homeserver or PKDNS resolver and switch providers without losing their data.
Censorship-resistant publishing
Public-key domains are published on the Mainline DHT instead of going through the usual domain registrars.
How much does Pubky cost?
Pubky is free and open source, with no paid tier.
- Protocol, SDKs and homeserver are MIT-licensed open source
- 1 GB of storage per user on Synonym's default homeserver
- You can self-host your own homeserver
Pubky has no pricing page or paid plan, and the pubky.app social app is free to join. Other homeservers set their own storage limits and may ask for an SMS code or a Lightning payment at sign-up to keep out spam. Full pricing on pubky.org. We checked these prices on .
