Comet vs Runway Pricing (2026)

Which one is cheaper?

Runway is the cheaper option, starting at $15/mo vs $19/mo for Comet.

Can I use either one for free?

Both offer free plans, so you can try each without paying. Start with whichever fits your workflow better and upgrade when you hit the limits.

How do they charge?

Both use a usage-based model, so the comparison is straightforward — it comes down to features and limits at each price point.

Which one is a better deal?

Depends on what you need. Comet: At $19/mo entry, they're positioning as the accessible alternative to heavier MLOps platforms — clearly going after teams that find tools like Weights & Biases or Arize too expensive or too complex for pure LLM tracing use cases. The academic free Pro tier signals they're also playing a long game on developer mindshare. Runway: At $35–$95/mo, Runway is priced as a serious professional tool — not a casual dabbler play, but not enterprise-only either. They're competing in the premium tier of AI video generation alongside tools like Pika and Sora, positioning themselves as the high-quality option for creators who care about output fidelity.
