TL;DR: Runway is the better pick if you want an all-in-one creative studio — generation plus a real video editor, motion tools and upscaling in one place. Kling AI is the better pick if you want the most raw generation for your money: its free tier refreshes daily and its paid credits go noticeably further per dollar. Both are credit-based, and on both, unused subscription credits are the thing to watch.
Bottom line: pick Runway for workflow and control, pick Kling for volume and value.
What are Runway and Kling AI, in one paragraph each?
Runway is a New York-based AI video platform built around its Gen-4 family of models. Alongside text-to-video and image-to-video generation, it ships a browser video editor, tools like Aleph for editing existing footage, Act-Two for performance capture, upscaling and watermark removal on paid plans. It is aimed at creators and teams who want generation and post-production under one login.
Kling AI, from Kuaishou, is a generation-first platform known for fluid motion and longer, more cinematic clips. It offers text-to-video, image-to-video and a large credit pool at aggressive prices. It has less of an editing suite around the generator — the draw is how much polished footage you can produce, and how cheaply.
Runway vs Kling AI: side-by-side comparison
| Feature | Runway | Kling AI | Edge |
|---|---|---|---|
| Free tier | 125 credits, one-time only | 66 credits every day, 720p, watermarked, non-commercial | Kling — it actually renews |
| Entry paid plan | Standard $15/mo ($12/mo billed yearly), 625 credits/mo | Standard $10/mo list price, 660 credits/mo | Kling on price |
| Mid plan | Pro $35/mo ($28 yearly), 2,250 credits/mo | Pro $37/mo list, 3,000 credits/mo | Kling on credit volume |
| Top plan | Unlimited $95/mo ($76 yearly), 2,250 credits plus unlimited Explore mode at a relaxed rate | Ultra $180/mo list, 26,000 credits/mo | Depends — relaxed unlimited vs a huge fixed pool |
| Credit cost of a short clip | Gen-4 generation is priced per second, so Standard buys roughly ten 5-second clips a month | A 5-second clip in standard mode costs roughly 10 credits, so Standard buys dozens | Kling |
| Editing tools | Full browser editor, Aleph video editing, Act-Two, Motion tools, upscaling | Generation-focused; light in-platform editing | Runway, clearly |
| Watermarks | Removed on paid plans | Removed on paid plans; free output is watermarked | Tie on paid |
| Commercial use | Allowed on paid plans | Allowed on paid plans; free tier is non-commercial only | Tie on paid |
Prices checked October 2026 from published plan pages and plan guides. Kling frequently runs first-month introductory discounts (for example Standard has been offered at $6.99 for the first month), so check the renewal price, not just the first payment, before you subscribe.
How does the free experience compare?
This is the biggest practical difference. Runway’s free plan is a one-time sampler: 125 credits, and when they are gone, they are gone. Kling gives you 66 credits every day. They expire in 24 hours and the output is 720p, watermarked and non-commercial — but you can test prompts daily and learn the model’s hit rate before paying anything.
Which one makes better video?
They trade blows by shot type. Runway’s Gen-4 line is strong on controlled, directable shots — camera moves, reference-driven consistency and editing an existing clip rather than starting over. Kling is frequently praised for natural human motion and for holding together longer, more ambitious shots. Neither wins every prompt, which is why Kling’s daily free credits are valuable: test your actual use case instead of trusting a showreel.
What does a month of real use cost?
Work backwards from credits, not plan names. Runway’s 625 Standard credits disappear quickly at full Gen-4 quality — most regular creators land on Pro ($35) for the 2,250-credit pool. On Kling, the same money buys far more attempts: 660 credits on Standard ($10) and 3,000 on Pro ($37 list). AI video always involves retries, so Kling’s cost per attempt is lower. If your workflow involves finishing clips, Runway’s editor can save you a second subscription elsewhere.
Which should you pick?
Pick Runway if you edit as much as you generate, you want one subscription for generation, cleanup and upscaling, or your team needs a shared workspace with a proper editor.
Pick Kling AI if generation volume is your bottleneck, you want a free tier you can use every day, or you already have an editor you like and just need footage to feed it.
Still deciding? Run Kling’s daily free credits for a week on your real prompts, and save Runway’s one-time credits for the shots Kling struggles with.
Frequently asked questions
Is Kling AI cheaper than Runway?
Yes, per generation. Kling’s Standard plan lists at $10/month for 660 credits against Runway Standard at $15/month for 625 credits, and a short Kling clip typically costs fewer credits. Runway’s price buys you the editing platform around the generator, not just generations.
Can I use Kling AI or Runway videos commercially?
On paid plans, yes for both. Kling’s free tier is non-commercial and watermarked, so treat any client or monetised work as a paid-plan job.
Do unused credits roll over?
Generally no. Runway’s monthly credits reset each cycle, and Kling’s subscription credits expire at month end. On Kling, separately purchased top-up credits have a much longer validity, which suits bursty project work.
Which is better for beginners?
Kling, to learn on — daily free credits let you practise without a countdown. Runway, to finish on — its editor beats assembling clips in a separate app.
