These 2 Free Chrome Extensions Let You Customize Any Website Instantly
These 2 Free Chrome Extensions Let You Customize Any Website Instantly
Ever land on a website that's blinding white at 2 AM? Or one with such terrible color choices you can barely read the text? You shouldn't have to suffer through bad design just because someone else made the website.
We built two Chrome extensions that solve this - and they're completely free. No subscriptions, no premium tiers, no "free trial" tricks. Just install and go.

InstantTheme - Find the Perfect Color Combination for Your Website
Install InstantTheme for Free ->
InstantTheme is built for founders, developers, and designers who are building websites and need to figure out which color combinations actually work. Instead of guessing hex codes in your CSS and refreshing a hundred times, you can play around with colors live on any website and see the results instantly.
Here's what it does:
- •Preview color themes live - try different color combos on any website in real time
- •Import color combinations - load an existing palette and see how it looks on a live site
- •Export color combinations - save your perfect palette and bring it into your project
- •Pick from presets or create your own custom combinations from scratch
- •Customize individual colors - tweak backgrounds, text, accents, and links independently
- •Export CSS - grab the generated CSS and drop it straight into your codebase
- •Download palette cards - get shareable visual cards of your color scheme
Who it's for:
- •Founders choosing a color identity for their product or startup
- •Developers who want to test color combos on live sites before writing code
- •Designers exploring how different palettes feel on real web layouts
Why it's free: Because figuring out colors for your website shouldn't cost money. We built this to solve our own problem and figured every builder could use it too.
ThemeJust - Universal Theme Engine for Every Website
ThemeJust is a universal theme engine that transforms how any website looks. It goes beyond simple dark mode - it's a full visual customization toolkit.
Here's what you get:
- •Dark mode that actually works on every website
- •Light mode override for sites with forced dark themes
- •Sepia mode for comfortable reading
- •High contrast mode for accessibility
- •16 beautiful built-in themes to choose from
- •Custom filters - adjust brightness, contrast, and saturation
- •Font customization - change fonts across any site
- •Smart auto-detect - automatically applies the right theme based on site design
Who it's for:
- •Anyone who browses at night and wants proper dark mode
- •People with visual accessibility needs (high contrast, larger fonts)
- •Users who simply want their browser to look better
- •Readers who prefer sepia-toned text for long articles
Why it's free: We believe everyone deserves a comfortable browsing experience. Dark mode isn't a luxury feature - it's a basic need.
Why We Made These Free (And Will Keep Them Free)
Let's be real - the Chrome Web Store is full of theme extensions that:
- •Charge $5/month for basic dark mode
- •Inject ads into your browsing
- •Collect and sell your browsing data
- •Lock the good features behind a paywall
We think that's wrong. Changing the color of a website shouldn't require a subscription.
Both InstantTheme and ThemeJust are:
- 1100% free - no hidden costs, no premium version, no upsells
- 2Privacy-first - zero data collection, zero analytics, zero tracking
- 3Lightweight - minimal impact on browser performance
- 4No ads - we don't inject anything into your browsing experience
- 5Published on Chrome Web Store - vetted and safe to install
