Vast.ai Alternatives

Direct alternatives to Vast.ai

Vast.ai is a GPU marketplace where hosts list hardware and prices move with supply and demand. Billing is per second across on-demand, interruptible and reserved instances (per its pricing page, September 2026). People look elsewhere for one of three reasons: another marketplace, a fixed rate card, or not managing instances at all. The list is grouped by those.

Another marketplace

• Lium: independent providers list whole NVIDIA hosts, from RTX 4090 to B300. Validators check the hardware before a node earns. Per-second billing, a CLI for starting pods and live prices published as JSON.
• RunPod: pods on Secure Cloud or a cheaper Community Cloud, billed per second as of September 2026. Also runs a serverless product, which lets a workload move to endpoints later without changing provider.

Fixed published rates

• Lambda: on-demand instances from 1x to 8x GPUs up to B300, plus 1-Click Clusters for multi-node training. Per-minute billing with no egress fees. Rates do not float with demand.
• Hyperstack: NVIDIA GPU cloud with per-minute billing, reserved and spot options plus data centres in Europe and North America.
• CoreWeave: Kubernetes-native GPU cloud built around multi-node clusters, quoted per 8-GPU node. Fits when the job has outgrown single rentals.

Not managing instances at all

• Modal: serverless platform driven from a Python SDK, with GPUs billed per second of actual compute and nothing for idle time. The Starter plan includes $30 a month of free compute (September 2026).
