VS. EVERYTHING ELSE

How we
stack up.

WORKS WITH YOUR STACK

Fits the way
your team works.

Cofactor runs end to end inside the tools your team already uses. Kick off a test from a Slack message, get the results back on the Jira ticket, and review the run in the pull request that started it. No extra dashboard to check.
