rrweb – record and replay debugger for the web

Anyone used replay.io and can compare both? Any limitations? This one is open source but there was no release in 2 years.

edit: actually they release frequently it's just latest builds are still pre-release.

RR's trick is to record any sources of nondeterminism, but otherwise execute code. One consequence is that it must record the results of syscalls.

Does Rrweb do the same for browser APIs and web requests?

The page mentions pixel-perfect replays, but does that require running on the same browser, exact same version, with the exact same experiments/feature flags enabled?

Posthog uses it for their session replay product as well

Very cool (and complex) implementation. I sponsor and use it for uxwizz.com

I also use a different system alongside it, that only records mouse movement/clicks/keyboard and replays them (so you can choose). RRWeb works well, but it uses more data/computing on both the client and the server-side.

I tried the "checkout form" demo and in the replay it showed what I typed into the credit card field. Any way to disable sensitive inputs like this?

Zipy is also a session replay and error tracking tool, which uses rrweb to capture the DOM. On top of that they have many small and big features which adds value to their product, must visit https://zipy.ai

Is there any browser extension based on Rrweb that would let me record my actions and export them to a file which could be then replayed by another person? I know commercial tools, I am wondering whether there is something free available.

Does it run locally? I inherently do not trust anything serverd on the web to be stable.

I studied rrweb's MutationObserver-based DOM event handling & recording when rebuilding the Notion editor a few years ago. I've never used the full thing but liked the code quality I encountered.

I wish we had an rr for nodejs.
