Hello HN,
Vlad, creator of Earthly here! Earthly is an open-source build automation tool. We use containers to make builds consistent across any environment, thus eliminating difficult to reproduce CI failures, because you can run your CI build on your laptop every time.
Second, isolation means that dependencies between steps need to be explicitly declared, and with this knowledge, earthly can infer parallelism.
Third, containerization gives caching abilities. We can tell if nothing’s changed since a previous run, and earthly can cache steps across build runs or even across machines. This results in massive speed gains. 2-20X, depending on the setup.
We trended with Earthly on HN a few times before, but we made significant progress since we last had a Show HN entry, 2 years ago [1]. The biggest part is that we recently launched Earthly Cloud, which includes Earthly Satellites, super fast remote runners that work with any CI. Earthly Cloud includes a generous free tier if you'd like to give it a try.
