Hey HN! co-founder here. It feels incredible to be sharing Replay with all of you. It's been a labor of love the past five years!

Replay started off as a simple experiment in what would happen if we added a step back button and rewind button to the Debugger. We quickly realized two things. First, nobody uses breakpoints. Second, being able to share is so much more powerful than being able to rewind.

Here’s how Replay works today. Somebody on the team records a bug with the Replay Browser and shares the replay url with the team. From there, developers jump in and add print statements. The logs appear in the Console immediately so you don’t need to refresh and reproduce a thing.

Over the past year we’ve talked to hundreds of users, recorded 2.5 million replays, and worked incredibly hard to ensure Replay would be fast, secure, and robust from the get go.

Hey! This looks interesting, have some feedback.

I downloaded the replay app, and couldn't figure out that in order to record I needed to sign in first. But not too big a worry, a few minutes of fiddling around later and I'm signed in.

After that, happily started recording and then hit stop. Replay then told me that my replay could not be viewed, because:

"Your Replay account is currently unactivated because you have not been invited to Replay by an existing user. Until you are invited, your authored Replays will be unviewable."

I do wish that this was told to me earlier, before I started recording. Also - anyone has an invite? XD

(Replay engineer): Hey davidten, thanks for trying Replay, sorry about the confusion. You definitely shouldn't need an invite. We're on it, getting a fix out now.
Hey David! This should be fixed now
Congrats on the launch, it looks great!

Would you care sharing the funding story? It looks like you guys have done quite some work ("After hundreds of user interviews and 2.5 million recordings") and already got funding. Did you develop in stealth mode with friends?
