Trusted by builders worldwide
From indie hackers to enterprise teams — developers choose NexaAPI for reliability, pricing, and simplicity.
“We switched from calling Replicate directly to NexaAPI and cut our image generation costs by 78%. The OpenAI-compatible SDK made migration trivial — literally changed one line.”
“The reliability is what sold us. We've been running 50K+ images/day for 3 months with zero downtime. The latency is consistently under 200ms even at peak load.”
“Finally, a unified API for all our AI needs. We use Flux for images, Whisper for transcription, and Claude for text — all billed together. Saves us so much overhead.”
“The pricing is genuinely 5x cheaper than going direct. I was skeptical but ran the numbers — NexaAPI saved us $3,200 last month alone on our video generation pipeline.”
“Support team is incredibly responsive. Had an edge case with batch video generation and they had a fix deployed within hours. That's enterprise-level service at startup pricing.”
“We prototyped our entire AI pipeline in a weekend using NexaAPI. The docs are excellent and the playground made it easy to test models before committing to integration.”
