(We've been around since 2014, so we pre-date them by 4 years)
Edit: I will give you that their web page header and pricing looks very similar.
Anyone can go on archive.org and verify that they changed their color scheme and header to ones very similar to CatchJS in Feb 2020, after CatchJS had used that look for 2 years. Thank you for also pointing out the pricing page, where the same is true.
I've now received a cease and desist from their attorney stating that the looks are too similar. It's nice that they've paid for an attorney to make my point for me, but they seem to have mixed up who did what here.
