Comet vs Modal FAQ

Which one is cheaper?
Comet starts lower at $19/mo, compared to $250/mo for Modal.
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?
Different approach here. Comet uses hybrid pricing, while Modal goes with usage-based. That changes the math depending on your team size and usage.
Which one is a better deal?
Depends on what you need. Comet: At $19/mo for Pro, Comet undercuts most enterprise-first MLOps and LLM observability tools that gate everything behind a sales call — this is a land-and-expand play aimed at developers and small teams who'd otherwise bounce off a 'contact us' wall. Modal: Modal sits in the middle-to-premium band of the GPU cloud/serverless compute space — pricier per-unit than raw cloud GPU rental (AWS, Lambda Labs) but selling the convenience of not managing infra, which undercuts fully managed ML platforms on complexity. They're chasing ML/AI teams who'd rather write Python and let infra disappear than fight Kubernetes YAML.
