About Tau

Tau is the open-source core of Taubyte, described as a fullstack workspace for humans and machines. It is a cloud platform written in Go that spans the development environment, building applications, and deploying and running them. Topics place it in serverless computing, WebAssembly, peer-to-peer distributed systems, CDN, and cloud-native platform-as-a-service. It is released under the BSD-3-Clause license.

The quickest way to try it is to start a local cloud with the dream tool. For real use, you deploy Taubyte to your own servers or VMs, either manually or with the automated Spore Drive tool, and the documentation at tau.how covers the platform, deployment, and getting started. A video series called the Hitchhiker's Guide to Taubyte provides guided demos.

The project welcomes contributions through a standard fork, branch, test, and pull request workflow, with good first issues labeled. Tau suits developers and platform teams that want to run their own cloud-like environment, avoid dependence on a single hyperscaler, and experiment with a WebAssembly-based serverless model.
