What is Paymattic?
Paymattic turns to security hardening after months of gateway-parity features.
Paymattic is a WordPress payments and donations plugin that has spent the year matching dedicated donation plugins: Gift Aid, fee recovery, a GiveWP migrator, Xendit subscriptions and Stripe card updates. Its last three releases lean on security: 4.6.26 hardened Stripe, Razorpay and Mollie flows and paginated the user dashboard server-side, 4.6.27 fixed Stripe subscription security and added custom webhook headers, and 4.6.28 tightened output escaping.
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.
Paymattic vs Polar: editorial side-by-side
Paymattic
2.5E-COMM
Paymattic turns to security hardening after months of gateway-parity features.
◆ Current state
Paymattic is a WordPress payments and donations plugin that has spent the year matching dedicated donation plugins: Gift Aid, fee recovery, a GiveWP migrator, Xendit subscriptions and Stripe card updates. Its last three releases lean on security: 4.6.26 hardened Stripe, Razorpay and Mollie flows and paginated the user dashboard server-side, 4.6.27 fixed Stripe subscription security and added custom webhook headers, and 4.6.28 tightened output escaping.
◆ Where it's heading
Three security-heavy releases in three weeks suggest an audit pass on the payment flows. Feature work has slowed to small developer options like webhook headers.
◆ Prediction
Expect gateway-parity features to resume once the hardening pass ends; which gateway is next is unclear from the 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.
