What is CartFlows?
CartFlows Pro 3.3.1 adds a single page layout to Instant Checkout.
CartFlows alternates hardening and small features. After a PatchStack-driven security patch, CartFlows 3.3.2 added bundle discounts to Frequently Bought Together, and CartFlows Pro 3.3.1 on November 9 adds a Single Page layout to Instant Checkout along with upsell and payment gateway fixes.
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.
CartFlows vs Polar: editorial side-by-side
CartFlows
5.0E-COMM
CartFlows Pro 3.3.1 adds a single page layout to Instant Checkout.
◆ Current state
CartFlows alternates hardening and small features. After a PatchStack-driven security patch, CartFlows 3.3.2 added bundle discounts to Frequently Bought Together, and CartFlows Pro 3.3.1 on November 9 adds a Single Page layout to Instant Checkout along with upsell and payment gateway fixes.
◆ Where it's heading
Feature work is focused on checkout and order value, with each release adding one conversion lever. Security fixes across the plugin family continue in between.
◆ Prediction
Expect further Instant Checkout layout options and upsell tweaks, with periodic security hardening releases.
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.
