What is Paid Memberships Pro?
PMPro 3.9 pulls scheduled billing into core and opens the plugin to automation.
Paid Memberships Pro v3.9 builds Subscription Delays and Set Expiration Dates into core with a date pattern builder, so sites can bill everyone on the first of the month or expire memberships on a set date. It also adds percentage and fixed discount codes, captcha on login and password reset, and a migration tool for deprecated gateways. Memberlite 8.0 shipped a day later with one layout system for pages, posts, archives and custom post types.
What is Polar?
Polar lets AI agents sign up, set up billing and complete checkouts.
Polar is now an official ChatGPT plugin and an approved Claude MCP server, so pricing, meters, credits and support can be run from a chat. Agents can create a Polar account on their own and hand it over with a claim code, hosted checkout exposes WebMCP tools, and agents can pay for buyers through Agentcard. The same release adds self-serve Stripe migrations and DNS domain verification.
Paid Memberships Pro vs Polar: editorial side-by-side
Paid Memberships Pro
5.0E-COMM
PMPro 3.9 pulls scheduled billing into core and opens the plugin to automation.
◆ Current state
Paid Memberships Pro v3.9 builds Subscription Delays and Set Expiration Dates into core with a date pattern builder, so sites can bill everyone on the first of the month or expire memberships on a set date. It also adds percentage and fixed discount codes, captcha on login and password reset, and a migration tool for deprecated gateways. Memberlite 8.0 shipped a day later with one layout system for pages, posts, archives and custom post types.
◆ Where it's heading
Both tracks are absorbing what used to live elsewhere: add-ons into PMPro core, page templates and meta boxes into a single layout setting. The v3.9 tools for developers, automation and AI agents, including WP-CLI commands, new REST endpoints and the WordPress Abilities API, are the new thread, since they make the plugin operable by software as well as admins.
◆ Prediction
Expect more add-ons to move into core and the automation surface to grow, given how prominently v3.9 presents it. The v4.0 referenced in earlier notes has no date in these entries.
Polar
6.3E-COMM
Polar lets AI agents sign up, set up billing and complete checkouts.
◆ Current state
Polar is now an official ChatGPT plugin and an approved Claude MCP server, so pricing, meters, credits and support can be run from a chat. Agents can create a Polar account on their own and hand it over with a claim code, hosted checkout exposes WebMCP tools, and agents can pay for buyers through Agentcard. The same release adds self-serve Stripe migrations and DNS domain verification.
◆ Where it's heading
After a summer of billing depth (credits, meter cycles, tiered usage pricing), Polar is now treating agents as both merchants and buyers. Stripe migrations target sellers ready to switch.
◆ Prediction
Expect more of the dashboard to become agent tools; the entries do not show pricing for agent-driven accounts.
