Ask HN: What CI tool do you use in 2019?

Semaphore (https://semaphoreci.com) recently introduced pay-per-use model with autoscaling, so you don’t have to pay a large sum just to run a few parallel jobs (disclaimer: cofounder here, open for questions).

Distelli (now puppet pipelines) let's you run as many builds as you want on your own hardware.

I have used Codeship Standard, CircleCI 1/2, and Semaphoreci 1. If you want a lot of flexibility I would suggest going with Circle. If you want a super cost effective option maybe look into Semaphoreci but it's more limited and less polished.

Thanks for using Semaphore Mike. Have you tried the new 2.0?

Out of curiosity (CodeShip founder here), what could we have done better?

Jenkins

Jenkinsfiles. Helps a lot when growing to more environments, toolset versioning in the code and environment reproducibility via Docker containers. Also best practice is to fork the Dockerfiles and build and host your own images in a registry.
