Which should you choose?

If your priority is managed model inference on aws, enterprise retrieval, agent building and multi-vendor model access, Amazon Bedrock is the stronger pick. If instead you care more about local image generation, diffusion workflows, controlnet pipelines and reproducible generation graphs, go with ComfyUI. For most people, trying both on a free tier is the fastest way to decide - they serve the same AI Models & Platforms space but differ in workflow and output style.
