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, now with PayPal in the box
Spree 6.0 shipped on 27 October as a rewrite of Spree Core, adding multi-vendor marketplace operations, B2B features, cross-border tax handling, stock reservation and an Admin MCP server. Four patch releases have followed in two and a half weeks, the latest 6.0.4 on 12 November, which mostly rolls SDK fixes and updates the CLI's agent skills, upgrade and code-generation commands. The 6.0.3 patch added the PayPal checkout provider to the published gems.
Polar vs Spree Commerce: 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.
Spree Commerce
5.0E-COMM
Spree 6.0 turns an open-source storefront into a marketplace, now with PayPal in the box
◆ Current state
Spree 6.0 shipped on 27 October as a rewrite of Spree Core, adding multi-vendor marketplace operations, B2B features, cross-border tax handling, stock reservation and an Admin MCP server. Four patch releases have followed in two and a half weeks, the latest 6.0.4 on 12 November, which mostly rolls SDK fixes and updates the CLI's agent skills, upgrade and code-generation commands. The 6.0.3 patch added the PayPal checkout provider to the published gems.
◆ Where it's heading
The 6.x line is in stabilisation: weekly patches across the Ruby gems and TypeScript packages, with the CLI absorbing much of the developer-facing change. The CLI's agent skills and the Admin MCP server point to Spree treating AI coding agents as a primary way developers build on it.
◆ Prediction
More 6.0.x patches at a roughly weekly cadence are likely, with CLI and SDK changes carrying most of the work until a 6.1 feature release. The entries give no date or scope for 6.1.
