Serverless Python compute that feels like local

Modal is the best developer experience for running Python workloads (ML, data pipelines, batch jobs) in the cloud. Pricing is fair and the developer experience is genuinely delightful.

CircleCIEVALUATE
The CI/CD platform losing share to GitHub Actions

CircleCI was the CI/CD default for a generation of engineering teams. GitHub Actions has displaced most new deployments through bundling. CircleCI remains usable but the strategic question is "why not GitHub Actions?"

Choose Modal if...

Engineering teams deploying ML inference, batch ETL, or AI pipelines without wanting to manage GPU infrastructure. Developer experience is the best in the category.

Avoid Modal if...

Applications with sustained 24/7 GPU utilization — dedicated cloud GPU instances (Lambda Labs, Coreweave) are cheaper at scale.

Choose CircleCI if...

Teams that need strong macOS/iOS pipelines or mature parallelism features and don't want to manage runners themselves.

Avoid CircleCI if...

Teams already deeply embedded in GitHub — GitHub Actions is free for public repos and tightly integrated with PR workflows.

Shared Integrations (1)

Both tools connect to these — you won't lose workflow continuity whichever you pick.

GitHub

Both suited for: small, medium, large companies

Since both tools target small and medium and large companies, your decision should hinge on the specific use case above rather than company fit. Try the AI Advisor to get a recommendation tailored to your exact stack.

Still not sure? Describe your situation.

The AI advisor knows both tools and your full stack. Tell it your company size, current tools, and what's not working — it'll tell you which one actually fits.
