Vallo provides on-demand, full‑Linux development sandboxes that include common runtimes, databases, storage, and a reverse proxy, all provisioned instantly and restored from snapshots in 3–5 seconds for fast warm starts. Users can launch and interact with these environments via a web UI, CLI, or Slack, with real‑time state synced across interfaces and secure live preview URLs that support OAuth, CORS, and service workers. Integrated GitHub support automates branch creation, pull‑request opening, and sharing of preview links, streamlining collaboration and code review.

Problem
Developers often waste time setting up and tearing down full Linux development environments, installing dependencies, configuring services, and managing access across tools, which slows iteration and hampers collaboration.
Solution
Vallo delivers on-demand, full-featured Linux sandboxes that include common runtimes (Node.js, Python), databases (Postgres, MySQL, Redis), storage (MinIO), and a reverse proxy, all provisioned instantly. Users can start sessions via a web UI, CLI, or Slack, with real‑time state synchronized through WebSockets, allowing seamless hand‑off between interfaces. Each sandbox is snapshot after the first build, enabling 3–5 second warm starts for subsequent sessions. Live preview URLs provide isolated subdomains that support OAuth, CORS, and service workers, and can be shared securely with HMAC‑signed tokens. Integrated GitHub support lets Vallo create branches, open pull requests, and attach live preview links automatically, streamlining the review workflow.
Target Audience
Vallo targets software engineering teams, DevOps groups, and individual developers who need fast, reproducible development environments and integrated code‑review workflows.
