The Verdict
Runway addresses indie developers building sophisticated video-powered products. The Gen-4 model offers unmatched creative control through inpainting, outpainting, and motion guidance—allowing developers to programmatically modify videos post-generation.\n\nThe Standard tier ($12/month, 625 credits) suits experimental workflows, while the Pro tier ($28/month, 2,250 credits) targets consistent production. Runway's credit-based model rewards efficiency: developers can reduce credit burn by targeting lower resolutions or using preview mode, making it predictable for cost-conscious teams bootstrapping SaaS products.
