GetWebstack gives fleets of AI coding agents isolated, production-like environments to build and test in, running locally or fully on-premise, with source code that never leaves the machine. AI agents write code blind. Without a live stack to run against, they generate against stale context, and the bugs surface later — in production, or when a
developer or tester finds what the agent could have caught itself. GetWebstack closes that loop. gws init analyzes a project and generates everything needed to run it; gws up brings the full stack — services, databases, HTTPS, routing — online in seconds with production parity and zero configuration. The platform is built for parallel work at the scale AI development now demands. Every agent and every developer gets its own isolated sandbox on the same cluster, so a fleet of agents can run at the same time without colliding. Each gets a live URL to test against real databases and APIs and validate its own output before a human reviews it. The same isolation powers on-demand preview environments for every pull request and end-to-end test suites that run against a real stack instead of mocks. GetWebstack integrates with AI coding agents through skills, working with Claude, Cursor, Codex, and other agents. Because everything runs locally or on the team's own cluster, GetWebstack fits teams with strict security and compliance requirements where code cannot go to a third-party cloud. It supports any common stack — Go, Python, Node, Rails, Django, React, Java, PHP, .NET and more — across macOS, Linux, and Windows. Target users include AI-native SaaS builders, development agencies running multiple agent-driven projects, and engineering teams adopting agent fleets. GetWebstack is built in France.
