# Features
Everything paid extensions need
Launch the billing pieces most extension developers end up rebuilding from scratch.
Lifetime Purchases
Sell one-time access for premium features without wiring up your own checkout, webhooks, or entitlement logic.
Subscriptions
Offer monthly or yearly plans and let crxbase keep access in sync as customers upgrade, cancel, or renew.
Single Active Subscription
Prevent users from repurchasing or stacking active subscriptions across plans.
Multiple Plans
Create Starter, Pro, and Team tiers so users can pay for the level of access that fits them.
Free Trials
Let users try paid features before they commit, then move them into a plan when the trial ends.
Browser Ready
Use the same billing flow across Chrome, Firefox, Edge, Safari, and other extension environments.
SDK Access Checks
Add the SDK to your extension and check whether a user can access a paid feature in a few lines.
Stripe Powered
Use Stripe for secure payment processing while crxbase handles the extension-specific billing layer.
Hosted Customer Pages
Give users a ready-made place to sign in, choose a plan, pay, and manage their subscription.
