Repro - a time-travel web inspector: https://repro.dev/
I am building a new tool for web developers that lets you record and replay websites from the browser devtools to effortlessly reproduce bugs and develop web apps faster. It's like session recording in FullStory or HotJar, but focused on developer experience and driven from the web inspector.
I am scratching my own itch; this is something I wish existed in browsers already and would have saved me countless hours in the last month alone. But... would it be useful for you?
I'm working towards an MVP later this year and I'd love to hear what you think!
This sounds ambitious, especially if done for multiple browsers. I would certainly try it. I'd probably want to leave it on all the time, if the idea is to be able to reproduce what would otherwise be a hard to reproduce bug. So it would be important that it wouldn't slow things down or eat up too much memory. I associate the idea of "code as movies" (i.e., something you can play, rewind, etc.) with Bret Victor.
