What is Paid Memberships Pro?

Membership-plugin ecosystem advances core comms and its Memberlite theme.

Paid Memberships Pro is an open-source WordPress membership platform shipping in two coordinated tracks: the core PMPro plugin and its Memberlite theme. Recent core work centers on a rebuilt email editor with Liquid syntax, profile pictures, and email logging, while Memberlite moved to a modern block-based foundation.

What is Smile.io?

Smile is growing by wiring itself into everyone else's app — including Shopify's AI assistant.

Almost everything on this feed is joint content with another Shopify app: Redo on abandoned carts, Stay AI on subscription churn, Loop on returns, Digioh on zero-party data, Judge.me on reviews. Each follows the same structure — take a moment in the customer lifecycle that another vendor owns, and attach loyalty enrolment or point earning to it. The exception is a genuine product launch, a Sidekick app extension that lets merchants ask Shopify's AI assistant about loyalty program performance.

Paid Memberships Pro vs Smile.io: editorial side-by-side

P2.5

Membership-plugin ecosystem advances core comms and its Memberlite theme.

◆ Current state

Paid Memberships Pro is an open-source WordPress membership platform shipping in two coordinated tracks: the core PMPro plugin and its Memberlite theme. Recent core work centers on a rebuilt email editor with Liquid syntax, profile pictures, and email logging, while Memberlite moved to a modern block-based foundation.

◆ Where it's heading

Both tracks are modernizing their foundations: PMPro is upgrading communication and admin tooling toward a v4.0 horizon, and Memberlite has been refactored from the ground up onto blocks. The cadence is regular and release-driven, with monthly add-on roundups filling the gaps.

◆ Prediction

Expect the Liquid-powered email system and block-based Memberlite to keep expanding, and continued groundwork releases pointing toward the referenced v4.0.

5.0

Smile is growing by wiring itself into everyone else's app — including Shopify's AI assistant.

◆ Current state

Almost everything on this feed is joint content with another Shopify app: Redo on abandoned carts, Stay AI on subscription churn, Loop on returns, Digioh on zero-party data, Judge.me on reviews. Each follows the same structure — take a moment in the customer lifecycle that another vendor owns, and attach loyalty enrolment or point earning to it. The exception is a genuine product launch, a Sidekick app extension that lets merchants ask Shopify's AI assistant about loyalty program performance.

◆ Where it's heading

Smile has stopped positioning loyalty as a destination app and started treating it as a layer that attaches to other moments — a return, a cancellation, a review, an abandoned cart. That is a distribution strategy as much as a product one: each integration borrows another vendor's install base and their moment of customer intent. The Sidekick extension extends the same logic to the platform layer, putting loyalty data where merchants are already asking questions rather than making them open Smile.

◆ Prediction

Expect more co-marketed integrations with adjacent Shopify apps on the same lifecycle-moment template, and further work exposing loyalty data through Shopify's own surfaces. Omnichannel recognition across retail and DTC is the thread most likely to become a product push.
