Key features
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
MCP connections to compatible AI agents
Real-time review and accept/reject agent edits
Automatic layout modes and infinite canvas navigation
Local data storage on device
Markdown support in descriptions
Change tracking and recovery
What makes it different
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
Same API for both human users and AI agents
No built-in AI needed - connect your own agents via MCP with no additional cost
Local-first design - all board data stays on your device
Shared context beyond conversation - the board becomes the reference point for ongoing collaboration
Full control over agent changes with real-time review
