Keep Testera free
Testera is free to use every day, with no card and no ads. If it helps you, chip in once, or become a Patron for more practice each day. Either way, you keep it free for learners who cannot pay.
Chip in, no account needed
Choose an amount and pay by card. No sign-up, and nothing to cancel later.
One-time contribution
Voluntary support for an independent team. Not a tax-deductible charity donation. Card payments handled by Revolut.
Become a Patron
More of everything, every day, for a year. What Patrons pay keeps Testera free for everyone else. Patron is a purchase of Pro access, not a charitable donation.
