Which one is for you
Pick OpenArt if
- Fits if you make short story videos or ads with the same characters throughout
- Works for people who want 100+ models on one balance in the browser
Look elsewhere if
- Skip it if you'll use the work commercially on Starter, which has no commercial rights; that starts at Plus for $27
- Not for you if you want a phone app or a public API, as it runs in the browser only
- Tight if you might want a refund, as finished generations and active periods generally aren't refunded
- Watch out: monthly credits reset each cycle, and extra credits ($15 for 5,000) need Plus or above
- Skip it if you want a free plan: you get a one-off batch of sign-up credits and nothing after
Pick RunDiffusion if
- Fits if you want ComfyUI or Auto1111 without owning a graphics card
- Works for designers who want Photoshop or Rhino plugins
Look elsewhere if
- Tight if you stay free: 100 tokens a day and files gone after 72 hours
- Watch out: premium image, video and editing tools aren't on the free plan
- Watch out: API mode and persistent extensions start at Creators Club + Runnit Pro, $41.79 on yearly billing
- Skip it if you want a fixed bill, as tokens run out faster on larger servers

Pro is $23.99 and the Team plan $179.99. |
| Free plan and trial | CFree credits when you sign up, with no card needed. It's a taste rather than a plan, as there's no free tier after that. | CUp to 100 tokens a day with the open-source apps and 10 GB kept for 72 hours. Premium tools aren't in it. |
| Features | B100+ image, video and audio models on one balance, consistent characters, Director for multi-scene films and ads, motion control, relighting, editing and upscaling.

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
