About Replay.io

The Replay Browser executes your code, producing recordings that are processed in the cloud backend. This allows users to access the time-traveling debugger directly from their browsers. This approach offers a number of advantages, including the ability to easily shift debugging from a solo activity to a shared one.

Instead of sharing a stack trace link, Replay.io allows users to share entire debugging sessions. This enables creation of more detailed overviews through annotations on code segments or network calls. The outcome is faster, more insightful debugging of even the most pernicious bugs. What might have taken days to fix can be resolved in hours.

EngFlow provided us with excellent support on how we could enable macOS and Windows chromium builds in remote execution. They also provided us with a dashboard where we can see detailed metrics around all of our builds, making it easy to see if a build issue is systemic or not.

4x faster builds, with visibility into every one

Transitioning to EngFlow’s solutions provided significant improvements, reducing 4 hour builds to under an hour. Replay.io has been empowered to run MacOS and Windows chromium builds through Remote Execution capabilities. EngFlow’s comprehensive dashboard provided detailed metrics across all builds, making it easy to see if a build issue is systemic or not.

EngFlow's fully managed model

Implementing EngFlow’s fully managed solution was easy. The detailed documentation and well thought out implementation points were a very helpful tool. EngFlow’s fully managed model.

It’s hard to imagine an initiative that EngFlow doesn’t impact for us, the experience that they provide is foundational to our ability to ship software.

Evolving With EngFlow

Crafting tools for developers is a challenge. Especially since everyone’s environment varies so much. Developers use a range of operating systems and generally push the boundaries of each and every system they use. Replay.io’s goal to design a complex solution that works in all these cases can seem almost impossible. EngFlow has supported that range of environments. The next step is extending remote execution to Replay.io’s Buck2 builds.

No matter what we are doing, no matter how crazy I think it sounds, EngFlow has always taken every challenge I have given them in stride, whether it was how old some of our software is or how custom we wanted our build tools to be.
