OUR MISSIONAbout Replay
We believe people understand what they can see, and if you cannot see what your software is doing, you cannot understand it.
Recording software so that you can replay it later is not a new idea. It is just incredibly difficult. We've been working on it for the past five years and have just recently gotten good at it.
We see a world where collaborating with Replay is second nature. When an engineer gets stuck, they share a replay. When a test fails, a developer clicks a link to view the replay. When a question is asked on Stack Overflow, folks comment directly in the replay. When an issue is filed in Github, maintainers help directly in replay. You see where we’re going with this!
We believe recording software at scale, will change the way software is understood. Recordings let us show type-hints in your editor and even suggest type improvements. Eventually, we can support the debugging process by suggesting hypothesis and eventually potential fixes.
If you’re excited to be a part of this journey and think Replay could be a good fit for your team please reach out to us at hi@replay.io.
Our Team
We're a distributed company, founded by people who have spent many years working on fully distributed teams. We work across the globe, so we focus less on hours and more on building a great product. We build for the long term: it's a relay, not a sprint.
Brian Hackett
CTO
Brian has had a longtime passion for helping people understand hugely complex software systems, starting with a Stanford Ph.D. and continuing through 10 years at Mozilla, where he worked on JavaScript VM optimizations and developed a precursor to Replay. He is a nomadic adventurer and enjoys sailing around Polynesia and van travel in the western US with his wife.
Dan Miller
Software Engineer
Dan started his career at Etsy where he worked on PHP runtimes and type systems and has been trying to help developers be more productive ever since. When not trying to express the "is a hot dog a sandwich" question using types, he can probably be found hiking or skiing if the weather is nice, otherwise he's probably playing Super Smash Bros.
Kannan Vijayan
Software Engineer
Kannan has implemented everything from an IrDA stack for Blackberry devices, to an mRNA sequence analysis platform for biology researchers, to a Javascript JIT for Firefox. Outside of work hours, he is learning his way around creating a nature preserve and small personal farm in a 100-acre patch of exploited land in rural Canada. He has always had his feet in two different worlds at any given time and aims to keep it that way.
Holger Benl
Software Engineer
Holger explored the world of programming languages from 6502 machine code to extracting LISP programs from mathematical proofs. These days he's mostly interested in creating developer tools. When he's not working on Replay or one of his VSCode extensions, he likes to read political blogs and books and watch asian movies.
Jon Bell
Designer
Jon has been excited about designing things on the internet since the 80s, and has led design teams at Twitter and Windows Phone. He lives in windy Wellington, New Zealand with his large family and loves writing, teaching classes, playing soccer, and trying to remember how to play the clarinet.
Sophie Haskins
Infrastructure Contractor
Sophie helps build the backend infrastructure of Replay. Through her career on infra teams at Etsy, Yelp, and GitHub, she's found the most joy in building systems that focus on the people they support, rather than pure technology. If she gets to share evocative colorful graphs along the way, all the better.
