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 Solidus?
solidus_admin 0.5.1 patches two security advisories a month after the 0.5.0 feature release.
solidus_admin, Solidus's newer admin interface, shipped 0.5.0 in October with editors for tax rates, payment methods, stores, zones, stock locations and option types, plus a move from Geared Pagination to Kaminari. 0.5.1 follows with fixes for two GitHub security advisories, after 0.4.1 fixed a stored XSS earlier in October.
Polar vs Solidus: 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.
Solidus
5.0E-COMM
solidus_admin 0.5.1 patches two security advisories a month after the 0.5.0 feature release.
◆ Current state
solidus_admin, Solidus's newer admin interface, shipped 0.5.0 in October with editors for tax rates, payment methods, stores, zones, stock locations and option types, plus a move from Geared Pagination to Kaminari. 0.5.1 follows with fixes for two GitHub security advisories, after 0.4.1 fixed a stored XSS earlier in October.
◆ Where it's heading
The new admin is filling in feature coverage while receiving its first steady flow of security reports, a sign it is seeing real production use. Security patches are arriving roughly monthly.
◆ Prediction
Expect further 0.5.x security patches and more settings editors before a 0.6.0; the entries do not show its timing.
