Try ZSky AI Free →Runway's Free Tier: One-Time Only
Runway ML provides 125 credits when you first create an account. This is presented as a free tier, but it functions more like a limited trial. Once those 125 credits are consumed, they do not renew. There are no daily, weekly, or monthly credit refreshes. The free tier is permanently depleted after first use.
Given that a single 5-second video generation with audio costs approximately 25 credits in Gen-3 Alpha, those 125 credits translate to roughly 2-3 short video clips. For anyone who wants to evaluate Runway's capabilities meaningfully, 2-3 clips is barely enough to form an opinion, let alone produce usable content.

AI Video Without the Subscription
AI video generation with audio has been one of the most expensive creative AI capabilities. Runway's Standard plan costs $12/month just to get 625 credits, and video consumes those credits rapidly. For many creators, the math simply does not work out. You pay $12/month but can only produce a handful of short clips.
ZSky AI's approach is fundamentally different. Video generation is built into the platform alongside image generation. Your unlimited free tier covers both. This means you can experiment with AI video, iterate on concepts, and produce short clips without paying anything. If you want ad-free instant generation, paid plans start at $19/month for Pro (video included at every tier).
Beyond Video: A Complete Creative Platform
Runway positions itself primarily as a video tool. ZSky AI provides a broader creative toolkit. AI image generation with multiple models, AI video generation with audio, and a growing suite of creative features all accessible from a single platform with a single credit system. You do not need separate subscriptions for videos and image.
