Server
The current version is v2.9.19.
The server is written in Go and compiles to a ~16MB native binary. A notable feature is the sparse set of dependencies the server relies on.
There are several ways to download and install the NATS server depending on the environment you are targeting.
If you are looking to design and run a production deployment of NATS, refer to the deployment section.

Nightly builds
Synadia hosts repositories for nightly Docker image builds off the main branch and the dev branch. The main branch tracks the next patch release, e.g. 2.9.17 → 2.9.18, while the dev branch tracks the next minor release, e.g. 2.9.x → 2.10.0.

docker run -p 4222:4222 -ti synadia/nats-server:nightly-main
Dev
docker run -p 4222:4222 -ti synadia/nats-server:nightly
