CI and hosting for your software projects, reimagined. Though the interface is familiar and simple, we use a novel and powerful infrastructure based on nix so you get fast CI with great caching, development environments, and easy server hosting.

We built this product because we knew Heroku from 15 years ago couldn't be the high point of hosting and CI/CD. We based it on a completely different technology, Nix, which makes it much easier to solve common pain points: - Caching between builds is automatic, making rebuilds fast with no effort on your part - It's easy to reproduce your CI locally, and exactly - Server deployments happen with zero downtime (if there's no persistence) - You get a development shell that you can easily enter and exit with all your development tools
