Best alternatives to Vast.ai in 2026
Big cloud providers (AWS, Google, Azure) rent out GPUs at a markup that covers their own massive data centers — but a lot of GPU power sits idle elsewhere, in smaller data centers and even individual machines. Vast.ai connects the two sides: GPU owners list their idle hardware, and developers training or running AI models rent it by the second, often at less than half the price of a traditional cloud, in exchange for less uniform guarantees about uptime than a hyperscaler offers. Vast.ai is a peer-to-peer GPU rental marketplace with three pricing tiers — On-Demand (guaranteed uptime, per-second billing), Interruptible (50%+ cheaper, can be preempted by a higher bidder), and Reserved (up to 50% off for 1/3/6-month commitments). It offers 68+ GPU types from RTX 3060s up to B200s across 40+ data centers, with market-driven pricing that shifts with supply and demand, no minimum usage hours, and no hidden charges. The company, an independent Delaware C Corp founded in 2016, reports 310% growth in 2024 to 17,000+ GPUs across 350+ hosts, is SOC 2 Type I certified, and was named a Fastest Growing Vendor by Ramp and Brex in March 2026.
