Tugboat QA is an automated deploy preview platform that gives teams a working website or web app for every pull request, branch, or tag. Instead of waiting for a shared staging environment, a sprint demo, or a local setup, Tugboat automatically builds isolated, on-demand environments and posts a working Preview URL or deployment link directly into GitHub, GitLab, or Bitbucket pull requests. Each code branch can have its own custom environment, letting developers mix and match service versions or branches without reconfiguring the application. Tugboat helps remove code review bottlenecks by making it easier for developers, QA teams, stakeholders, and clients to view, test, and approve changes before they are merged. Inside each Preview, teams can access running services, service logs, build logs, output logs, Lighthouse reports, visual diffs, captured mail, preview statistics, and terminal access for troubleshooting or collaborative development.
