crxpay

Free trials

A trial your users actually finish.

Card-required, card-optional, reverse trials, or gifted extensions — three to thirty days. Typed state transitions, no client-side clock-fiddling, no “wait, when did my trial end?” tickets.

Anatomy of a trial

Eight days. Two emails. One honest conversion.

crxpay handles the clock, the reminders, and the handoff to paid. You write zero timers. Day 8 arrives and the status flips — or it doesn’t, and a reminder email goes out instead.

Length, card policy, grace — all from the dashboard.

Three controls cover every trial model we’ve seen in production. Change them without shipping a new extension build.

Trial models supported
  • Standard trial
    Free access for N days, then charge the card on file.
  • Reverse trial
    Start on Pro, fall back to Free if the user doesn’t subscribe.

    No card collected. Convert with a one-click upgrade on day N.
  • Gifted extension
    Pre-activated trial via a redemption code. Perfect for launches.

SDK

Start a trial in one call. React to it in three more.

The SDK exposes typed events for every transition — trial_started, trial_ending, converted. No polling, no setInterval, no clock-drift bugs.

popup.ts
import { crxpay } from '@crxpay/sdk';

const trial = await crxpay.startTrial({
  plan: 'pro-monthly',
  days: 7,
  collectCard: false, // card-optional
});

if (trial.ok) {
  toast('Welcome — 7 days of Pro on us 🎉');
  enableProMode();
}
