Best alternatives to Blaxel in 2026

Running one AI agent for a demo is easy. Running thousands of agents that each need their own isolated computer, that start instantly when work arrives and cost nothing while sitting idle, is a different engineering problem entirely — one most teams shouldn't have to solve themselves. Blaxel is infrastructure built specifically for that job: it hands each agent a disposable sandbox that boots in milliseconds and disappears (and stops costing money) the moment it's done. Blaxel is agent-execution infrastructure that supports over 50,000 concurrent microVMs, with sandboxes booting in milliseconds and resuming from a paused state in roughly 25ms — fast enough that agents can be spun up per-task rather than kept running continuously. It includes Agent Drive, a distributed filesystem for sharing state across multiple agents working together, persistent durable volumes for data that needs to survive between runs, and a programmable network layer with egress control and static IPs for agents that need a stable, whitelistable identity when calling external APIs. Founded in 2024 and backed by Y Combinator, Blaxel prices on a pay-as-you-go basis (around $0.0000115 per GB-RAM-second of compute, plus $0.12/GB-month for storage), starts new accounts with $200 in free credits, and offers optional flat-rate subscription tiers from $20/month.
