Hi there, this is actually a user-supported open source plugin: you can see the repo at https://github.com/hCaptcha/hcaptcha-wordpress-plugin
All of the modules like Contact Form 7 were supplied by users who didn’t want to wait for other plugins to add native support, but the single best way to get hCaptcha is to email the plugin authors like Contact Form 7 to add hCaptcha natively; it will usually take them an hour or two at most.
Aside from that, we accept PRs and release new versions regularly.
