awesome on a regular browser, but I tried it on brave, firefox and safari on my mobile site and it fails to verify. As such, I cannot use this plugin.

I’ve installed ALTCHA on a non-WordPress website a little under a year ago, and it’s been protecting that website from spam registrations (these were an issue there!) ever since.
Now I’m using it on a couple WordPress websites as well, and it seems to work just as fine, albeit it’s only been a few days.
If you’ve ever been annoyed by having to repeatedly select busses or fire hydrants, or move parrots around, and you don’t want to push that experience onto your visitors, ALTCHA can be the solution. It’s non-intrusive to normal users (the calculation performed only takes a couple seconds), but is a great way to deter spammers, who would rather automatically submit a few hundred forms than spend that same amount of CPU time on a calculation required to only submit that one form on your page.
Oh, and I love that this plugin is open source and no-nonsense. It will never clutter your WordPress UI with calls to upgrade to pro or notifications about Black Friday sales. It adds a single sub-menu item under Settings, and is very civil in all regards. And it also respects your visitor privacy: no data will be transmitted to other servers than yours by default due to having it installed, unless you explicitly configure it to use ALTCHA’s cloud API, which adds some extra functionality in addition to filtering out bots.
All that said, it’s not a silver bullet of course, and you may want to keep Akismet enabled too as a second line of defence.

I’ve discovered this plugin a few months ago, switched about 10 sites from recaptcha to altcha in self-hosted mode and it’s working beautifully at the moment. I did have some issue with LiteSpeed Cache enabled at first, but 1.9.0 seems to have fixed that!

Auf der Suche nach einer rechapta Alternative für WordPress….sind wir auf altcha gesto?en. Die Integration ist einfach. Funktioniert mit cf7 (inkl userem selbst entwickelten Plugin für cf7).
