• Free with no snapshot quota — run it as often as you like.
• Baselines stay in your repository, which suits regulated or air-gapped environments.
• Simple JSON configuration that a junior engineer can extend.

• The lowest false-positive rate in the category — the reason teams migrate to it from pixel-diff tools.
• Ultrafast Grid replaces a lot of cross-browser execution with one render pass.
• Root-cause analysis points at the DOM/CSS change behind a visual diff.

• Pixel-diff comparison means font rendering differences between machines cause false failures; Docker is effectively mandatory.
• No hosted review or approval workflow — approving means committing new images.
• Reference images bloat the Git repository over time.

• Expensive, and priced opaquely.
• Substantial platform to learn beyond simple snapshot comparison.
• Overkill if you have twenty pages and a stable design.

Teams that need visual testing without a SaaS vendor or a per-snapshot bill.

Enterprises where visual correctness across many browsers is a business requirement.
