Your app's whole backend, like Firebase. Except nobody can read your data, not even us.

04 · Build

Write it in Rust, ship it in one package.

You write the app's state and methods. Replication, auth, storage and the sealed channel come with the platform.

1. Write your app's state and methods in Rust with calimero-sdk.
2. Build it with mero-app-build, and try it on a three-node dev cluster with merod local.
3. Deploy one signed package, logic and frontend together, to Calimero Cloud.

#[app::state]
pub struct KvStore {
    items: UnorderedMap<String, LwwRegister<String>>,
}

#[app::logic]
impl KvStore {
    pub fn set(&mut self, key: String, value: String) -> app::Result<()> {
        self.items.insert(key, value.into())?;
        Ok(())
    }
}

06 · Open source

The runtime is open source.

The node, the SDK and the protocol are on GitHub, with a full protocol reference you could reimplement a node from.
