What is OpenBoxes?
OpenBoxes 0.9.9 turns to purchase-order shipments and pick imports after a summer of data rules.
OpenBoxes is an open-source inventory and supply chain system used by health-facility operators, released roughly quarterly with hotfix branches between. Version 0.9.9 on 27 October improved readability and filtering for purchase-order shipments and pick imports. Earlier in the year 0.9.8 made product import reject unknown categories and patched three GHSA advisories, and 0.9.7 added TransactionSource records for inventory provenance.
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.

OpenBoxes
2.5E-COMM
OpenBoxes 0.9.9 turns to purchase-order shipments and pick imports after a summer of data rules.
◆ Current state
OpenBoxes is an open-source inventory and supply chain system used by health-facility operators, released roughly quarterly with hotfix branches between. Version 0.9.9 on 27 October improved readability and filtering for purchase-order shipments and pick imports. Earlier in the year 0.9.8 made product import reject unknown categories and patched three GHSA advisories, and 0.9.7 added TransactionSource records for inventory provenance.
◆ Where it's heading
The 0.9.x line is working through warehouse workflows one at a time: cycle counts and record stock in spring, import validation in summer, outbound shipments and picking now. Each release tightens how data enters the system rather than adding new modules.
◆ Prediction
A 0.9.9 hotfix within weeks is likely, given that every recent minor has been followed by one or more.
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.
