Runway Gen-4

vivago.ai

Best overall

For most everyday users, vivago.ai is the clear winner because it's completely free and covers the basics (text-to-image, text-to-video, upscaling) without any paywall. Runway Gen-4 delivers far higher video quality and advanced features like motion brush and character generation, but its free tier is very restrictive and paid plans start at $12/month. The single biggest difference is price: vivago.ai costs nothing, while Runway Gen-4 requires a subscription for meaningful use.
