VisualRunner vs BackstopJS: hosted platform or open-source CLI?
BackstopJS is a free open-source visual regression CLI. Compare it with VisualRunner for setup effort, baselines, scheduling, collaboration and production monitoring.
BackstopJS is a popular open-source command-line tool: you describe scenarios and viewports in a JSON config, it captures them with a headless browser and produces an HTML diff report. VisualRunner provides the same capture-and-compare core as a hosted product, with page discovery, scheduling, history and team review built in.

Choose BackstopJS when you want free and fully self-managed
For a developer comfortable with Node.js, BackstopJS is a capable, zero-cost way to compare a set of URLs against reference screenshots. You control the browser, the config and where images are stored.
npx backstopjs init # creates backstop.json
npx backstopjs reference # capture baselines
npx backstopjs test # compare and open the report
npx backstopjs approve # accept the new screenshotsWhat you take on with a self-managed tool
Somebody has to keep the config in sync with the site, store and version baselines, run the job on a schedule, stabilize flaky captures, and share reports with people who do not use the terminal. That work grows with every page, language and viewport.
- Maintaining scenario lists as pages change
- Storing baselines outside the repo
- Scheduling and alerting
- Sharing results with non-developers
Choose VisualRunner when the site outgrows a config file
VisualRunner discovers pages from a sitemap or crawl, captures every language and viewport, runs monitors on a schedule, keeps a searchable visual history and lets reviewers approve changes or raise issues in the browser.
Questions
Frequently asked questions
Is BackstopJS still a good choice?
Yes, for small sets of pages owned by developers. The trade-offs appear when the page list, languages and number of reviewers grow.
Can I migrate a BackstopJS URL list to VisualRunner?
Yes. Paste the URLs or import them from a spreadsheet, choose viewports, and the first run becomes your baseline.
Does VisualRunner have a free option?
Local capture in the browser extension is free. Cloud monitoring is a paid plan with a trial.
