Screenshot Testing Python Packages

wontfit

Find out what won't fit before your users do. Preview your running web app at phone and tablet widths side by side, name the element that overflows, and fail the build when a layout breaks.

shotbox

Reproducible screenshots of real programs in a sealed session: X11 on Xvfb or Wayland under headless sway, with a private D-Bus and scratch home. Waits for readiness instead of sleeping, drives keys and the pointer, and compares pictures. Python, CLI and Playwright helpers.

testivai

Local-first visual regression testing for Playwright, Selenium, WebdriverIO, Python, Java and Ruby. Every screenshot is paired with a DOM and computed-style snapshot, so a diff arrives as a verdict — "style-only change on button.cta", "likely render noise" — not a wall of red pixels. MIT, no account, nothing uploaded.

visual-guard

Visual regression detection that catches UI shifts DOM assertions miss
