What builders say
Real users. Real halves.
"Switched my whole agent stack to Dopp. Same Claude Opus 4.8, literally half my bill. The key capped itself exactly where I funded it — zero surprise."

"I was burning $400/mo on GPT-5.6 Sol. On Dopp that's $200 and I got the same tokens. Set it up in 2 minutes with the base_url."
@cipher_ko · ML engineer
"The Nano Banana Pro at half price is unreal. Image quality is identical to the vendor and I save 60%+ on every batch."
