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.
What is Smartstore?
Smartstore is monetising EU compliance while quietly wiring AI through the admin surface.
The .NET storefront ships one substantial release every six to nine months, each pairing a runtime jump with a batch of features. 6.4.0 moved to .NET 10 and introduced commercial Withdrawal and Warranty plugins built directly against EU rules for digital withdrawal and harmonised guarantee labelling. Before that, 6.3.0 and 6.2.0 ran a sustained WCAG accessibility sweep across the storefront and checkout, and 6.1.0 added DeepSeek and Gemini as AI providers.
Polar vs Smartstore: editorial side-by-side
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.
Smartstore
0.0E-COMM
Smartstore is monetising EU compliance while quietly wiring AI through the admin surface.
◆ Current state
The .NET storefront ships one substantial release every six to nine months, each pairing a runtime jump with a batch of features. 6.4.0 moved to .NET 10 and introduced commercial Withdrawal and Warranty plugins built directly against EU rules for digital withdrawal and harmonised guarantee labelling. Before that, 6.3.0 and 6.2.0 ran a sustained WCAG accessibility sweep across the storefront and checkout, and 6.1.0 added DeepSeek and Gemini as AI providers.
◆ Where it's heading
Two arcs are running in parallel. Regulatory surface — accessibility, withdrawal, warranty labelling — is being productised as paid plugins, which turns compliance obligations into a revenue line for a project whose core is open source. Separately, AI has moved from a text-writing helper to editing images in the Media Manager by prompt, with the provider list broadening rather than committing to one vendor.
◆ Prediction
Expect the next major to continue the pattern: a runtime or framework bump, further EU compliance plugins on the commercial side, and AI reaching more of the catalog and content authoring workflow.
