EnvMark

About

EnvMark is a browser extension for developers, QA engineers, and teams who frequently switch between development, test, staging, and production environments.
Many internal systems look almost identical across environments, which can lead to accidental edits, submissions, or testing in the wrong place. EnvMark helps prevent that by matching pages with user-defined URL rules and displaying clear visual markers such as badges, watermarks, and title prefixes.
It can also keep test accounts close at hand, allowing users to fill configured account fields when needed. EnvMark only fills input fields and never submits forms automatically.
Install EnvMark if you want to clearly identify environments, reduce costly mistakes, switch between test accounts faster, and manage environment configurations in a simple local-first tool.
