Overview

OpenComputer runs AI agents on persistent virtual machines that hibernate between turns and wake with state intact, so a run resumes after a crash, disconnect or redeploy. An agent is a source-controlled directory holding its identity, instructions, tools, connections and durable workspace, deployed to a stable agent ID that aliases immutable deployments. The VMs are also sold on their own.

Best for: Developers deploying LLM agents that must survive crashes, and teams wanting bare persistent VMs
Pricing: VM compute is billed by usage: $0.004 per minute ($0.24 per hour, quoted as $168.72 per month) for 4 GB and 1 vCPU, with 20 GB disk included and $0.0000001 per GB-second of disk; volume discounts are by enquiry.
Runs on: WebSelf-hostedCLI

Strengths and trade-offs

Strengths

Sessions hibernate when idle and wake with state intact
Full VM with filesystem and OS access, not a container
Resize memory and CPU on a running VM without restarting
Per-minute billing; you pay only while the VM runs

Trade-offs

Published sizing slider stops at 16 GB memory
One 4 GB VM left running is quoted at $168.72 per month
Agent product is gated — the site asks you to talk to the team
Local development is described only via OpenCode
