Diffrun [dif-run]
There's healthy debate about where the name came from. Some say it's short for "diff your run". Others insist it's what you shout when CI finally goes all-green. We say it's a reminder to always ship with confidence.
Once upon a time (well, 2021)
Two engineers, tired of scrolling endless CI logs trying to answer one simple question — "what actually changed?" — decided to build the answer.
A weekend hack became a team tool. A team tool became a product. And when three other companies asked for access unprompted, Diffrun was born. We've been shipping fast and staying transparent ever since.
We published over 20 integrations in our first year, expanded across 40+ countries, and we're on a mission to bring total pipeline clarity to engineering teams of all sizes.
Trusted by over 10 million test runs — and counting
Our platform has powered hundreds of zero-regression deploys, saved thousands of engineering-hours in root-cause analysis, and showed teams just how powerful a crisp diff can be.
We believe every developer deserves instant clarity — and that's the real magic of Diffrun. Discover our best features here.
Built with a spark of precision
In our team, we blend deep backend infrastructure expertise with delightful UX. Senior engineers, product designers, and reliability experts spend thousands of hours perfecting every diff view, every insight, every alert.
We believe everything begins with…
Asking the hard questions
Treating each other well
Always being bold
For developers of every shape and size
Seeing how much solo developers loved the clarity Diffrun brought, we knew that feeling was too good to keep from larger teams. Our enterprise tier began with a single Slack message, and now we've got SAML SSO, audit logs, and even SLA-backed uptime.
Whether you run GitHub Actions, GitLab CI, or a fully custom pipeline — Diffrun just connects.
