🧪 Parallel testing on the fastest hosted CI
Boosters automatically parallelize your Rails tests with one click. Skip the manual setup and get faster feedback on the fastest cloud CI platform — no config, no infrastructure, no slowdowns.
“Boosters is very easy to set up and a major time saver for our team. We reduced build time from over 2 hours to 13 minutes. Getting faster feedback from the tests has made it less likely that we will need to switch to another task while waiting on tests.”

“Getting up and running with Boosters was the kind of experience we’ve come to expect from Semaphore — easy and user friendly. We saw tremendous benefits without having to tweak a bunch of dials. We can now get back to focusing on our code.”
