All plans have a 30 day no-strings-attached trial. The free plan will be free forever.
As an example let's imagine that you run one build every day Monday to Friday and each build takes 5 minutes to run. That's around 20 builds per month which works out at 100 build minutes in total per month. In this case you will be perfectly comfortable on the Free forever plan.
As many as you want! Each plan allows you unlimited projects and unlimited number of builds. The only limit is your plans build minutes. This means that if you have many projects that you build rarely you will be fine on the Free forever plan.
Yes! You can upgrade or downgrade or cancel your plan at any time!
We realize that you are trusting us with a critical part of your workflow so we won't suddenly stop running your builds when you hit your upper limit. However we will give other builds priority over yours. This will mean your builds might take much longer than normal. We'll give you plenty of notice when we see that you're getting close to your limit so you'll have plenty of time to prevent hitting the limits.
