The Verdict
Novu is built for saas developers and product teams, with a focus on multi-channel-notifications and notification-center. Stable Diffusion targets developers and artists and leads with text-to-image and img2img.
Both tools come in at similar price points ($0.0025/mo for Novu, $0.01/mo for Stable Diffusion), so pricing won't make the decision for you.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
This is a genuinely close comparison. If you can, sign up for both free trials (where available) and run a one-week test with your actual team tasks before deciding.
