Payments for Apps & ExtensionsComing soon

Charge for your app or extension in an afternoon

Payments your app or extension can drop in.

Drop in a few lines of JavaScript and Pay handles the rest — subscriptions, one-time payments, trials, hosted checkout, and every webhook — through Stripe and PayPal.

Launch news only — no spam, unsubscribe anytime.

Everything you need, nothing you don’t

A tiny SDK

getUser(), openPaymentPage(), and an onPaid listener are most of what you need. Check paid status and start checkout in a few lines.

Subscriptions & one-time

Recurring plans or single purchases, through Stripe and PayPal, without wiring either integration yourself.

Nothing to build

Hosted payment, trial, and login pages come ready — no checkout UI to design, host, or maintain.

Trials that just work

Offer free trials and let Pay track entitlement, so your app or extension always knows who's paid.

Webhooks, handled

Pay processes provider webhooks and keeps entitlements in sync, so you don't babysit payment events.

A dashboard that tells you

Revenue, payments, success rate, and payouts in one clean view built for indie developers.

The SDK

Monetize without becoming a payments engineer

App and extension developers want to ship features, not integrate Stripe webhooks. Pay gives you a small client SDK and a hosted backend, so adding paid plans is a config step — not a project.

The platform

Checkout, trials, and webhooks — off your plate

Pay hosts the payment, trial, and login pages and processes every webhook, keeping entitlements accurate. You get a clean dashboard; your users get a smooth checkout.

Questions, answered

Developers who build applications and browser extensions and want to charge for them — with subscriptions or one-time payments — without building a payments backend.
