Buildkite vs. Snap CI vs. Buildbot

CI and build automation tool that combines the power of your own build infrastructure with the convenience of a managed, centralized web UI. Used by Shopify, Basecamp, Digital Ocean, Venmo, Cochlear, Bugsnag and more.

Snap CI is a cloud-based continuous integration & continuous deployment tool with powerful deployment pipelines. Integrates seamlessly with GitHub and provides fast feedback so you can deploy with ease.

BuildBot is a system to automate the compile/test cycle required by most software projects to validate code changes. By automatically rebuilding and testing the tree each time something has changed, build problems are pinpointed quickly, before other developers are inconvenienced by the failure.
