A browser extension that gives developers a drop-in subscription and one-time payment layer built specifically for Chrome and Edge extensions
Google deprecated Chrome Web Store payments in 2020, leaving extension developers with no native billing and forcing them to jury-rig general SaaS tools not designed for the extension context. Existing third-party options are either single-developer hobby projects with limited reliability, or broad merchant-of-record platforms (Lemon Squeezy, Paddle) that require a full checkout page and server-side webhook handling that clashes with the stateless, permission-sandboxed extension model. A purpose-built SDK handles auth, entitlement checks, subscription lifecycle, and trial gating entirely from within the extension background service worker, with zero required backend.

Competitive LandscapeFREE
| Product | Does | Missing |
|---|---|---|
| ExtensionPay | Stripe-backed payment API purpose-built for Chrome extensions, handles subscriptions and one-time payments without requiring a developer-managed server. | Single-developer project with limited SLA, no trial-gating logic, no usage-based billing, no multi-browser support beyond Chrome, no built-in analytics on conversion or churn. |
| BrowserBill | Recurring subscription and one-time payment platform for browser extension developers, Stripe-backed, supports Chrome and Edge. | Small early-stage product, no documented SDK for background service workers, no trial management, no entitlement propagation to extension popup context. |
| Lemon Squeezy | Full merchant-of-record SaaS billing with checkout pages, subscriptions, tax compliance, and a Stripe-managed payments option as of 2026. | Not designed for extensions: requires redirect to external checkout page (breaks UX inside a popup), no service-worker-compatible SDK, no entitlement polling without a backend webhook receiver. |
| Paddle | Merchant-of-record for software companies, handles global tax, subscriptions, and analytics. | Heavy enterprise focus, no extension-native SDK, checkout flow requires full browser page navigation incompatible with popup-confined extension UIs, minimum revenue thresholds exclude indie extension devs. |
