Previewhost: Local previews for Git worktrees
Previewhost runs an application's frontend, API, databases, and setup jobs locally, giving each preview its own URL and isolated services.
- For
- Developers testing multiple Git worktree environments
- Worth noticing
- Failed replacements leave the previous working services available while new requests switch only after readiness.
Field notes
Previewhost models each local preview as an environment containing services and setup jobs, with a primary service exposed at the environment URL. Configuration can pass named service bindings such as a managed PostgreSQL URL without placing a fixed port or password in the project file. The dashboard reports status and logs for CLI or MCP owners, while each replacement receives its own attempt record so a failed update can be distinguished from the version still serving requests.
