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 Spree Commerce?

Spree 6.0 turns an open-source storefront into a marketplace and B2B platform

Spree 6.0 shipped on 27 October as a rewrite of Spree Core, with a 6.0.1 patch two days later. The release adds multi-vendor marketplace operations (seller onboarding, commissions, split payments through Stripe Connect, a seller dashboard and API), B2B features such as company hierarchies, per-customer catalogs, order minimums and purchase-order capture, cross-border tax handling, purchase orders and stock reservation, and an Admin MCP server. The 6.0 release candidates also carried a batch of Store and Admin API security fixes.

Polar vs Spree Commerce: editorial side-by-side

P
Polar
E-COMM
6.3

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.

S5.0

Spree 6.0 turns an open-source storefront into a marketplace and B2B platform

◆ Current state

Spree 6.0 shipped on 27 October as a rewrite of Spree Core, with a 6.0.1 patch two days later. The release adds multi-vendor marketplace operations (seller onboarding, commissions, split payments through Stripe Connect, a seller dashboard and API), B2B features such as company hierarchies, per-customer catalogs, order minimums and purchase-order capture, cross-border tax handling, purchase orders and stock reservation, and an Admin MCP server. The 6.0 release candidates also carried a batch of Store and Admin API security fixes.

◆ Where it's heading

Spree has moved from a headless storefront engine toward full commerce operations: marketplace, wholesale, warehousing and tax. Its developer surface keeps shifting to TypeScript packages and React dashboards, with Admin and Seller APIs now deprecating fields instead of removing them.

◆ Prediction

Expect 6.0.x patches to keep consuming pending changesets; Spree Enterprise previews in the dashboard suggest paid tiers built on 6.0 features.
