What is Checkfront?
Checkfront upgrades Adyen checkout ahead of Apple Pay and Google Pay
Checkfront handles bookings for tours and activities and publishes monthly release notes focused on operational depth. September upgraded Adyen checkout to SDK v5 with a client key field, preparing accounts for Apple Pay and Google Pay, and fixed capacity mismatches, duplicate bookings from unclear Square verification, and GetYourGuide bookings that created extra inventory. Earlier months added Adyen phone payments without 3DS blocks, timeslot closures, shared assets and staff assignment in the Daily Manifest.
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.

Checkfront
0.0E-COMM
Checkfront upgrades Adyen checkout ahead of Apple Pay and Google Pay
◆ Current state
Checkfront handles bookings for tours and activities and publishes monthly release notes focused on operational depth. September upgraded Adyen checkout to SDK v5 with a client key field, preparing accounts for Apple Pay and Google Pay, and fixed capacity mismatches, duplicate bookings from unclear Square verification, and GetYourGuide bookings that created extra inventory. Earlier months added Adyen phone payments without 3DS blocks, timeslot closures, shared assets and staff assignment in the Daily Manifest.
◆ Where it's heading
Payments and inventory accuracy are the recent focus: Adyen work two months running and several fixes where availability shown to guests did not match real capacity.
◆ Prediction
Apple Pay and Google Pay through Adyen are the likely next payment addition, since September's upgrade was described as preparation for them.
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.
