What is Polar?
Polar fills out the merchant-of-record toolkit B2B SaaS actually needs — meters, multi-currency, team accounts.
Polar's recent run is a focused buildout of B2B billing primitives that compete directly with Stripe Billing and Lago. Meter Units add value-multiplier support so usage metrics can be ingested in raw counts and priced in customer-friendly units. Pending subscription changes are now visible in both dashboard and customer portal. Multi-currency product pricing lets merchants set per-currency prices on the same product. Team Member Management for B2B brings owner/billing-manager/member roles. Every entry appears duplicated in the feed.
What is Spree Commerce?
Spree ships an official TypeScript SDK, formalizing its headless commerce bet
Spree, a Rails-first open-source commerce platform, has made its headless path official with a stable TypeScript SDK. @spree/sdk 1.0.0 gives full Store API v3 coverage, a provider-agnostic Payment Sessions API, multi-market support, generated types, and three auth modes. The 1.0.1 follow-up adds SDK extensibility and fills in missing delivery and fulfillment totals.

Polar
6.3E-COMM
Polar fills out the merchant-of-record toolkit B2B SaaS actually needs — meters, multi-currency, team accounts.
◆ Current state
Polar's recent run is a focused buildout of B2B billing primitives that compete directly with Stripe Billing and Lago. Meter Units add value-multiplier support so usage metrics can be ingested in raw counts and priced in customer-friendly units. Pending subscription changes are now visible in both dashboard and customer portal. Multi-currency product pricing lets merchants set per-currency prices on the same product. Team Member Management for B2B brings owner/billing-manager/member roles. Every entry appears duplicated in the feed.
◆ Where it's heading
Polar is no longer just an indie-developer monetization tool — the recent surface reads like a serious B2B SaaS billing platform. Usage-based pricing primitives (meters with custom units), multi-currency, scheduled subscription changes with customer-portal visibility, and B2B team management collectively close the gap with the standard checklist enterprise buyers compare against. The trajectory is clear: target SaaS companies that previously had to choose between Stripe Billing's complexity and a smaller-but-simpler tool.
◆ Prediction
Expect more usage-based primitives — tiered metering, prepaid credits, free-tier graduation flows — given the meter-unit foundation just landed. Tax-handling improvements (more jurisdictions, automated reconciliation reports) are likely next given the multi-currency push. SOC 2 / SAML enterprise checklist items will probably become visible too if the B2B push continues.
Spree Commerce
0.0E-COMM
Spree ships an official TypeScript SDK, formalizing its headless commerce bet
◆ Current state
Spree, a Rails-first open-source commerce platform, has made its headless path official with a stable TypeScript SDK. @spree/sdk 1.0.0 gives full Store API v3 coverage, a provider-agnostic Payment Sessions API, multi-market support, generated types, and three auth modes. The 1.0.1 follow-up adds SDK extensibility and fills in missing delivery and fulfillment totals.
◆ Where it's heading
The direction is API-first commerce: a typed, framework-agnostic client positioned as the recommended way to build storefronts on Spree, whether on its Next.js storefront or a custom frontend. The quick 1.0.1 iteration signals the SDK is now an actively maintained primary developer surface, not a one-off release.
◆ Prediction
Expect continued SDK iteration filling Store API gaps and likely deeper alignment with the Next.js storefront, making the typed client the default integration path over raw API calls.
