Had a look at their website [1]. Initial thoughts: this is a bit ridiculous, I can just build that myself. And in fact, I have done already.
Thoughts after about 3 minutes of browsing: OK, this actually makes sense and I see why people would pay for this. The value proposition is definitely there
I pay for it for my team... it's expensive to be honest, but worth it IMHO. Building it would be a ok, supporting it a pain.
If you work on a small startup, not worth it... on a Big corp with a lot of bureaucracy? It's worth it I think.
We have tried self-hosting it, but it's always a pain to allocate people on infra to do it, so I gave up and started paying for it for my teams, and they love it.
Thanks, "I could build that" → "oh, that's what the other 90% is" is pretty much how Unleash started for us too. What does your homegrown version do? Always interested in where people draw the line between building and adopting.
