Payments, with all the pain left in.

painomore is a fake payment provider for testing integrations. It speaks Stripe's API, hosts the payer's checkout and the bank's side, and misbehaves on purpose: late and duplicated webhooks, timeouts after the work is done, soft declines on renewals, bank apps that ask twice. Every misbehaviour is written down, so you can see what was done to you.

Sign-in is for the development team. Payers need no account: checkout pages open from the merchant.
