Dark Mode for Testlio (Unofficial)

Dark mode for the Testlio platform. Adjustable brightness and contrast, auto mode that follows your OS, Alt+Shift+D to toggle.

Testlio doesn't ship a dark theme — this extension fixes that. Built by a Testlio freelancer for late-night test runs. Dark Mode for Testlio applies a clean, adjustable dark theme to everything on testlio.com (both the freelancer portal and the platform workspace) and touches nothing else. WHAT IT DOES • Turns Testlio's bright interface into a soft, readable charcoal theme • Keeps photos, avatars, screenshots, country flags, and logos in their true colors • Preserves the meaning of color — pass/fail greens and reds stay green and red • Paints the theme instantly on page load, with no white flash MAKE IT YOURS • On / Off / Auto — Auto follows your operating system, so Testlio goes dark when your computer does • Brightness and contrast sliders with live preview: drag them while a Testlio tab is open and watch it change • Three presets: Midnight (deep and punchy), Balanced, and Bright (light charcoal) • Alt+Shift+D toggles dark mode from anywhere • The toolbar badge shows the current state (ON / OFF / AUTO) • Settings sync across your Chrome profile MADE FOR TESTERS Built by a member of the Testlio freelancer community. One tip from the field: flip it off (Alt+Shift+D) before capturing test evidence, so your screenshots show the platform's true colors. PRIVACY • No data collection, no analytics, no tracking — nothing ever leaves your browser • Runs only on testlio.com pages • Uses a single permission ("storage") to remember your theme settings DISCLAIMER This is an unofficial community tool. It is not affiliated with, endorsed by, or sponsored by Testlio, Inc. The Testlio name is used only to describe what the extension is compatible with. If Testlio ever ships a native dark theme, simply uninstall this extension.
