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 Squarespace?
Squarespace adds a business account and spending card, plus SMS campaigns for the holidays.
Squarespace's November update opens Squarespace Balance to eligible US Squarespace Payments merchants: one account for payouts with same-day access to earnings, rewards on saved money and a spending card, run through Stripe and partner banks. The same update adds SMS Campaigns with consent and opt-out built in, and price and availability product filters. It follows October's customer profiles, transactional email and new Link payment methods.
Polar vs Squarespace: 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.
Squarespace
6.3E-COMM
Squarespace adds a business account and spending card, plus SMS campaigns for the holidays.
◆ Current state
Squarespace's November update opens Squarespace Balance to eligible US Squarespace Payments merchants: one account for payouts with same-day access to earnings, rewards on saved money and a spending card, run through Stripe and partner banks. The same update adds SMS Campaigns with consent and opt-out built in, and price and availability product filters. It follows October's customer profiles, transactional email and new Link payment methods.
◆ Where it's heading
Each monthly update moves Squarespace further from site builder toward the merchant's whole back office: payments, invoicing, customer records, email, now SMS and the account the money sits in. The AI site generation and AI visibility work from mid-year has given way to commerce and money features ahead of the holiday season.
◆ Prediction
Expect December's update to extend Balance or SMS Campaigns, for example automations or availability beyond the first eligible US merchants; the notes give no timeline.
