Hippo, the WebAssembly PaaS

Hippo is the easiest way to deploy and serve applications compiled to WebAssembly.

WARNING: This is experimental code. It is not considered production-grade by its developers, nor is it "supported" software.

DeisLabs is experimenting with many WASM technologies right now. This is one of a multitude of projects (including Krustlet) designed to test the limits of WebAssembly as a cloud-based runtime.

Hippo takes a fresh spin on the PaaS ecosystem, taking advantage of the technology WebAssembly brings to the space.

Hippo works like this: A WebAssembly package is bundled up as a bindle. Bindles are collected together in a bindle server that you can search. Hippo uses bindle under the hood for storing and organizing applications.

Using the hippo command line interface, you can upload new releases or prepare a bindle for local development. In the future, you can use this CLI to create applications, configure channels, gather logs, attach TLS certificates, and other commands you’d expect to use with a PaaS.

Hippo provides a web interface for users to register new accounts, access their applications, and create new environments for testing.

Hippo makes it easy to run WebAssembly applications and services at scale.
