Quick answer

Updated

Kenerate is an Unstable Diffusion alternative for people who don't want a monthly plan. Unstable Diffusion (unstability.ai) is still running in 2026 with one monthly Pro plan, 120+ models and 40,000+ LoRAs, allowing adult content for users 18+. Kenerate gives 25 free credits, then one-time credit packs that never expire, across 80+ models — including Chroma (tagged Uncensored) — plus editing and image to video. Both block content involving minors.
