I want to purchase WAHA Plus (WAHA Pro), is it one time purchase?
According to Pricing page:
It doesn’t require monthly subscriptions, once installed on your server - it always works! (until WhatsApp made backward-incompatible changes, and you have to update the image, or you need to reinstall it on new server )
Meaning that the installed WAHA will continue to work even after you subscription got expired. Unfortunately, WhatsApp makes backward incompatible changes and when it happens we need to keep up and update the docker image, which means that you need to update your WAHA as well, otherwise it won’t work 😔 It happens like every 3-6 months or so and depends on your country as well.
In order to update WAHA you need to have active docker key (which you get on WAHA Patron Portal), meaning at this time you need to be active subscriber.
In summary, it’s not one time purchase, it’s rather “every 3-6 months” purchase to get the latest update.
💡 We recommend staying subscribing, so we can keep developing awesome product for you! Your support the only reason why we’re able to publish and maintain the project 🫶
