Modal
Verified
Serverless containers and GPUs that agents can treat as a computer.
Modal runs containers and GPUs as functions: scale to zero, fast start, no cluster to babysit. It is general compute that agent products use as a sandbox or as training/eval hardware. It is not an IDE.

Editorial take
Modal is a computer you program with Python decorators. Factories use it when the sandbox is “run this image” and when someone needs a GPU. It is not Firecracker-as-a-product and not a coding agent. Idle billing is a vendor claim — read the current pricing page.
Strengths
- Serious serverless containers, including GPUs.
- Good fit for eval jobs and generated-code execution.
- Python-native developer UX.
Limitations
- Cloud-only platform. Not your VPC unless they say so on the day you check.
- General compute, so isolation defaults are your problem to configure.
- Not issue-to-PR.
