This pulls our prebuilt public Docker image and needs no registry credentials. If you instead build the image from the Dockerfile in this repo, its hardened base images come from Docker's dhi.io registry, which requires a one-time docker login dhi.io with any free Docker account — see Building from source.
Our Philosophy
The top 1% of companies spend thousands of hours building their own in-house experimentation, feature flagging, and analytics platforms. The other 99% are left paying for expensive 3rd party SaaS tools or hacking together unmaintained open source libraries.
We want to give all companies the flexibility and power of a fully-featured in-house platform without needing to build it themselves.
