Hello, thanks for your feedback. We changed this last year, indeed.
The Standard plan, priced $149/month includes up to 10 API docs, as well as unlimited users, where most of our competitors charge per user, which can get the total bill very high, very fast.
Note that we apply grandfathering: any customer who started a subscription before a plan changes will keep the same price and set of features as long as they renew their subscription (exceptions may apply for our free plan).
Unfortunately, we're aware that this model cannot be satisfying for all of our users, and we're deeply sorry about this.
We are closely monitoring this topic, and will do our best to find new options that can satisfy the vast majority.
