Chromatic vs BackstopJS
Feature checklists rarely decide anything. What decides it is the pricing metric, who has to write the tests, and which limitation you can live with.
Entry price
From $179 per month (Starter, 35k snapshots)

Open sourceWhat drives the bill
The metric that actually scales your invoice.
Snapshot-based billing: Starter $179 for 35k snapshots, Pro $399 for 85k, then Enterprise. Overage runs about $0.008 a snapshot. TurboSnap, which only re-tests stories affected by a change, is the main cost control. Cross-browser coverage beyond Chrome starts at Starter.
Free and open source. You pay in engineering time and CI minutes.

Strengths
- Zero-effort setup if you already have Storybook — stories are the tests.
- The hosted review UI is genuinely usable by designers and product managers.
- TurboSnap dramatically reduces snapshot cost on large libraries.
- 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.
Limitations
- Strongly tied to Storybook; without it much of the value disappears.
- Component-level, not full-page — it will not catch a broken page layout.
- Snapshot pricing still adds up on a big design system.
- 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.
Best for
Design-system and component-library teams already invested in Storybook.
Teams that need visual testing without a SaaS vendor or a per-snapshot bill.
All of these integrate with: Playwright.
