Great service with a lot of flexibility; parallelization is great

What do you like best? The parallelization is great. You configure your yml file with a lot of prebuilt docker images and specify how many containers it can use. Very intuitive. Also newly added support for Windows VMs is a very welcome and long needed addition. Now all major platforms (Linux, Mac, Windows) are supported. What do you dislike? The performance plan where you can run unlimited builds is quite pricey, they count both your active users and the amount of resources you ...

Effective tech, lacks transparency

Changes to their API are often compatibility breaking, little transparency on performance considerations, slow to respond to feedback and fix known issues.

Good self-service with web interface.

Nice experience

What do you like best? It is easy to use Documentation is good. What do you dislike? There is no support for outside git repos. We are using codebasehq.com for some of our repositories, and we can not use circileci for them. What problems are you solving with the product? What benefits have you realized? We had a jenkins instance. It was old but working. One day, it is hacked. It is always better to use a service rather than maintaining a server.

Just running builds for PRs, running test suites and making sure nothing is broken.
