| Security | The README recommends matching the Docker container user to the local environment to improve security and avoid file ownership problems. | BrowserStack states that it is SOC 2 Type 2 compliant and that this compliance extends to its data centers and platform. |
BackstopJS suits developers who need repeatable screenshot comparisons for web apps, including teams using CI reporting or multiple browser engines. It is available for Linux, macOS, and self-hosted use.
