The record

Purpose: Spunto provides isolated development environments, production deployments, and operations tools on compute the customer controls.
AI sandboxes: Each sandbox provides a Linux environment with Docker, persistent storage, a terminal, and HTTPS URLs for ports.
Agent interfaces: Agents can use Spunto through its REST API or MCP server, with scoped keys.
Development environments: Workers run devcontainer-compatible configurations and can be opened in a browser or accessed over SSH.
Deployments: Spunto runs grouped Docker services with custom domains, automatic TLS, pre-deploy hooks, logs, and one-click service presets.
Integrations: Spunto documents GitHub integration for deploy keys, Git credentials, and repository cloning, and supports connecting Google Cloud, Hetzner, or a user's own server.
Security: Workers and services use isolated Docker bridge networks, and the node agent connects outbound without requiring inbound ports or firewall changes.
Secrets and code: The homepage says secrets are encrypted and write-only, while repositories are cloned on connected nodes rather than Spunto's servers.
Access control: Organizations support owner, admin, and member roles; API keys can be scoped to limit their permissions.
Supported agents: Any agent able to call an HTTP API or MCP can create sandboxes and run commands; built-in tasks support Claude Code, and other command-line agents can be configured as custom commands.
Compute providers: Spunto can provision Google Cloud VMs, including spot instances, or connect to Hetzner and any Linux machine with Docker.
Limitations: The homepage says snapshots, forking a running sandbox, and a streamed desktop are not yet available.
Audience: Spunto describes the platform as intended for teams needing reproducible, isolated environments for onboarding, feature branches, AI agent sandboxes, or production services.
