Przelewy24 vs PayU vs Tpay vs Dotpay, which Polish gateway should I use with Magento?

Four mainstream Polish PSPs — all support BLIK + bank-transfer (Pay-By-Link) + cards. Pick by feature mix + pricing:

• Przelewy24 (P24) — the most-installed Polish PSP. Pay-By-Link to ~20 Polish banks (mTransfer, iPKO, Pekao24, ING etc.) + BLIK + cards. Free Magento 2 module. Fees ~1.4–1.9% per transaction.
• PayU Poland — second-largest, Naspers/Prosus-owned. Strong on installments + BNPL (PayU Raty), good fraud tools. Official Magento module, fees similar to P24.
• Tpay — Polish PSP focused on simplicity + fast onboarding. Good for < PLN 10M stores. BLIK + 18 banks + cards + Apple Pay / Google Pay.
• Dotpay — older Polish PSP (now part of Nets / Nexi). Stable, banking-grade, but UX dated; better for B2B or invoice-heavy flows.
• Blue Media / Autopay — specialist in fast-bank-transfer + BLIK, often used as a complement to P24/PayU.

Recommendation: P24 + PayU dual-rail for B2C (lowest cart-abandonment + redundancy), add Tpay if you need installments, add Stripe for cross-border EUR / USD checkout.
