Dark mode: is it worth adding?
Add dark mode when your audience expects it and you can maintain two well-tuned themes. It aids comfort and feel but doubles design and testing.
Dark mode is genuinely loved by many users and expected in some products — but it is also real, ongoing extra work. Adding it reflexively because it feels modern is a common mistake. The honest answer to 'should I add dark mode?' is: only when your audience expects it and you can commit to doing it well.
Weigh the upside against the real cost before deciding.
The upside
Dark mode can reduce eye strain in low light, save power on some screens, and feel modern and considered. For developer tools, content apps and products people use for long stretches, many users actively prefer it and will notice its absence.
The real cost
Supporting dark mode means designing and testing two versions of everything — contrast, imagery, shadows, borders, states. Done half-heartedly, with a few inverted colors, it looks worse than not having it at all. It is a second theme to maintain forever, not a one-time toggle.
| Add it when | Skip it when |
|---|---|
| Your audience expects it | It is a simple marketing site |
| It is a product used for hours | Branding is light and minimal |
| You can maintain two themes | You cannot commit to both |
| You will tune it properly | It would be a rushed afterthought |
When to add it
Add dark mode when your audience expects it and you can commit to tuning both themes properly. For a simple marketing site with light branding, it is often an unnecessary burden that doubles your work for little gain. Match the decision to your specific product and audience, not to the trend.
