Hello Product Hunters! 👋
I’m Alex, CEO and founder of NEXA AI, and I’m excited to share Nexa SDK: The easiest On-Device AI Toolkit for Developers to run AI models on CPU, GPU and NPU
At NEXA AI, we’ve always believed AI should be fast, private, and available anywhere — not locked to the cloud. But developers today face cloud latency, rising costs, and privacy concerns. That inspired us to build Nexa SDK, a developer-first toolkit for running multimodal AI fully on-device.
🚨 The Problem We're Solving
Developers today are stuck with a painful choice:
- Cloud APIs: Expensive, slow (200-500ms latency), and leak your sensitive data
- On-device solutions: Complex setup, limited hardware support, fragmented tooling
- Privacy concerns: Your users' data traveling to third-party servers
💡 How We Solve It
With Nexa SDK, you can:
- Run models like LLaMA, Qwen, Gemma, Parakeet, Stable Diffusion locally
- Get acceleration across CPU, GPU (CUDA, Metal, Vulkan), and NPU (Qualcomm, Apple, Intel)
- Build multimodal (text, vision, audio) apps in minutes
- Use an OpenAI-compatible API for seamless integration
- Choose from flexible formats: GGUF, MLX
📈 Our GitHub community has already grown to 4.9k+ stars, with developers building assistants, ASR/TTS pipelines, and vision-language tools. Now we’re opening it up to the wider Product Hunt community.
Best,
Alex
@alexchen4ai Super exciting launch! 🚀 On-device AI that’s fast and private is exactly what a lot of devs have been waiting for. Love that you’re making it easier to tap into GPU/NPU acceleration without the usual complexity. Congrats on bringing this to the PH community!

This is a truly a breakthrough local AI toolkit. Unlike Ollama, NexaSDK literally runs any model (Audio, Vision, Text, Image Gen, and even computer vision models like OCR, Object Detection) and more. To add more, NexaSDK supports Qualcomm, Apple, and Intel NPUs, which is the future of on-device AI chipset.
I look forward to hearing everyone's feedback.
I enjoy how it lowers the barrier to building with AI.
