PhotoDemon is a traditional photo editor emphasizing portability, format compatibility, and no-install operation. It offers layers, painting tools, content-aware fill/resize (non-AI), macro recording, and batch processing—all free. It supports niche formats like PSD, PSP, XCF, DDS, PCX, and PDF import. In contrast, Runway Gen-4 is an AI-first platform: it generates video from text, image, or video; transforms styles; and edits with inpainting/outpainting. Its Studio editor (2026) adds timeline-based trimming and stitching. Runway also includes Aleph 2.0 for one-frame video editing, Runway Agent 2.0 for AI-driven ad campaigns with analytics, Seedance 2.0 for multi-input generation, and recently released Seed Audio 1.0 for text-to-audio (speech, sound, music). It integrates with Adobe Premiere Pro, After Effects, Final Cut Pro, DaVinci Resolve, Unreal Engine, and third-party AI models like Kling 3.0, Veo 3.1, and Gemini Omni Flash. PhotoDemon has no such integrations or video capabilities.
Pricing compared
PhotoDemon is completely free and open-source—no tiers, no credits, no subscription. Runway Gen-4 uses a freemium model: a free tier with limited credits, then paid plans: Standard ($12/mo, 625 credits/mo, 1080p exports), Pro ($28/mo, 2250 credits/mo), Unlimited ($55/mo, 5250 credits/mo), and Enterprise ($155/mo, 12,500 credits/mo). While Runway’s free tier is nice for exploration, serious use quickly requires a paid plan. If you want any AI video generation, you pay; if you don't, PhotoDemon remains free forever.
