Pricing
Standard: Free forever. Plus: €9/month. Pro: €25/month. Team plan: No subscription, pay per machine and per AI use from prepaid balance in US dollars. Machine sizes: R0 $5/month, R1 $10/month, R2 $30/month. AI pricing per million tokens: Rool® 1 input $0.35, cached input $0.07, output $0.70. Rool® 1
Compute: $0.015 per GiB-hour (approximately $0.000004167 per GiB-second, billed by the second). Storage: $0.02 per GiB-month for retained incremental RootFS data and memory checkpoints. Network ingress and egress currently free. Object-store GET and PUT requests free. New users receive $5 free credi
Key features
Persistent memory that builds knowledge graphs over time
File storage and management with version control
Collaboration with shared access and permissions
Multiple Rool Machines per account
Built-in connectors and custom MCP servers
Full data export and API access
Progressive Web App and mobile apps
Hourly credit refills with daily limits
Rool 1 and Rool 1.5 AI models
EU infrastructure with self-hosted models
Automatic filesystem growth as storage fills
Pause compute without losing work or paying compute charges
Resume to same environment on demand
Access files while paused without waking compute
Public HTTP services with auto-resume capability
Command-line interface (s0 CLI) for agent-native workflows
Incremental checkpoints to avoid full filesystem copies
Scoped API keys and team-based access controls
On-demand file reads without downloading entire filesystem
What makes it different
Private machine isolated at VM level, not just by access rules
Hosted entirely in the EU with self-hosted AI models
Never trains AI models on your data
Free forever plan with no credit card required
Persistent filesystem across pause/resume without duplicating data
Pay only for compute time used; paused sandboxes have zero compute charges
Automatic filesystem growth so agents can install and persist unlimited tools
