MemberPress

Pros: It doesn't take over your installation and hog the wordpress admin like many plugins do. It keeps itself in its own section and has a reasonable number of settings.

Memberpress should really be considered a membership framework upon which you can assemble a versatile range of membership and subscription based sites rather than an out of the box product, i.e. there's still a lot of work to do yourself but memberpress will help you more than it will cause headaches, and that is not always the case with wordpress membership plugins.

Really fantastic rule making section means that you can create things like tag and category restrictions or take it to a whole level of complexity and control by restricting custom post types and taxonomies. The latter approach is excellent for those combining this with custom fields and really customising the admin panel heavily.

Integrations are not endless but are well considered and usually best of class i.e. Stripe, Paypal, Mailchimp, Drip etc...

Cons: Because it's a framework really, it is possible to use memberpress badly if you are not an experienced wordpress developer. Not making good rules for restriction and relying on per page restriction for example can set you up for a messy future and makes you very dependent on memberpress.

The forms and payment workflow could be nicer.

The user self-service section needs some work although it can be styled with CSS. it would be nice if the defaults were a bit more modern and adapted a bit better to themes.

More action based hooks would be useful to make a very customisable membership signup and upgrade flow.

Overall: Robust wordpress membership platform which we use for delivery of paid courses and learning management.

Acts as a complex framework on which you can build a very elaborate membership site rich in features and with quite customisable behaviour.
