If you're open to something more powerful, there is DaVinci Resolve [0]. It's free but proprietary.
For fully open + browser based there is mebm [1]

Of course the main issue with that recommendation is that Davinci Resolve is geared towards professionals. That means the tool can do much more things than any amateur will ever need or understand. If you invest a little time to understand the basics and don't tend to click random things without knowing what they do, this should not be any issue at all. Resolve has a very clear workflow and you can always skip the parts you don't need (e.g. color correction, audio mixing).
The real advantage here is that if you learn it, there is no ceiling to how professional your results can get in terms of post production. But don't forget the golden rule:
Shit in, Shit out
What other software were you using aside from Blender?
I've been considering resuming work on it, and this comment certainly provides a ton of motivation. thanks!
I also tried mebm months ago, but it's not really mature. (Is there a version hosted somewhere? the domain mebm.xyz is no longer available)
