I built a failover daemon for Vast.ai spot GPUs, found 5 real bugs testing it
⚡ SpotWarp: Never Lose a Training Run to a Spot GPU Eviction The real cost of a Spot GPU eviction was never the few minutes of downtime — it's the hours of training progress that vanish with it. SpotWarp is a lightweight, 100% local Python daemon that runs continuous automatic backups of your workspace in the background, so an eviction never costs you your work. Sub-minute cross-cloud failover (Vast.ai ⇄ RunPod) is what turns that protected workspace into a hands-off recovery, but the backup is the part that actually saves you.

Sub-minute cross-cloud failover (Vast.ai ⇄ RunPod) is what turns that protected workspace into a hands-off recovery, but the backup is the part that actually saves you. Save up to 70% on GPU compute bills by safely using Spot pricing instead of on-demand — the eviction risk that normally makes that a gamble is exactly what SpotWarp removes. 🆚 Spot GPU Eviction: Standard vs.
