Selium is a software framework and runtime for building scalable, connected applications. With Selium, you can compose entire application stacks with **strict capabilities**, **typed I/O**, and **zero infrastructure**.
You get the ergonomics of an application platform, with the safety properties of a capability system:
- **Zero DevOps**: a batteries-included platform that is entirely composable in code.
- **Ergonomic I/O everywhere**: first class composable messaging, even when interacting with network protocols.
- **End-to-end type safety**: seamless type support across process and network boundaries.
- **No ambient authority**: guests only receive the capabilities you grant them at runtime.
**Status:** alpha (APIs and project structure are still evolving).

## What happened to the messaging platform?
**The previous project can be found in the _legacy_ branch.**
A messaging platform was never our end-goal. We have taken all of our learning from building that platform and applied it to the network stack for Selium 1.0.

## Getting started
The fastest way to orient yourself is by [checking out an example](examples/).
You can also find [Selium modules in their own repo](https://github.com/seliumlabs/selium-modules). These modules add significant extra functionality on top of the core platform.
