Who Should Consider Switching?
Simple Custom CSS and JS is a solid, proven plugin. It is not broken. But there are specific user types who will get meaningfully more value from Simple Custom Code:
- Users who want AI assistance — Describe a CSS tweak or JS behavior in plain English and have it written for you. Simple Custom Code includes this free. Simple Custom CSS and JS has no AI integration at any tier.
- Non-developers and beginners — The visual CSS editor lets you click any element and style it without touching code. Not available in Simple Custom CSS and JS at any price point.
- Gravity Forms users — The visual Gravity Forms CSS Customizer in Simple Custom Code (free) has no equivalent in Simple Custom CSS and JS at any tier.
- Free users who need developer tools — Error detection, smart autocomplete, multiple editor themes, and execution order control are all free in Simple Custom Code. In Simple Custom CSS and JS, all four require a Pro upgrade starting at $48.50.
- Agencies managing multiple client sites — At $39.60/year for 25 sites vs $148.50/year for 50 sites, Simple Custom Code Pro is dramatically more affordable — and includes optimized loading that SCCJ Pro doesn't offer.
- Developers who care about clean output — Source comment removal and cache mode in Simple Custom Code Pro keep your published HTML clean. Neither is available in Simple Custom CSS and JS Pro.
When to Stick with Simple Custom CSS and JS
We believe Simple Custom Code is the better tool for most users today. But there are genuine reasons some users should stay with Simple Custom CSS and JS:
- You need code revision history — Simple Custom CSS and JS Pro includes full change history with diff comparison. Simple Custom Code does not yet have this (it is planned).
- You use the live preview feature — Previewing CSS or JS changes via a shareable URL before going live is unique to Simple Custom CSS and JS Pro. Particularly useful for client approval workflows.
- You need snippet import / export — Simple Custom CSS and JS Pro handles moving snippets between installations. Simple Custom Code does not yet support it (planned).
- You have deep existing workflows — If your team has years of processes built around Simple Custom CSS and JS and the missing features above don't apply to you, the cost of switching may outweigh the benefit.
How to Switch in 6 Steps
Migrating is straightforward. Your snippets need to be copied over manually, but the process takes only a few minutes — even for sites with many snippets.
- Install Simple Custom Code — Download the free version from WordPress.org or search "Simple Custom Code" in the WordPress plugin directory and activate it.
- Copy your existing snippets — In WordPress admin, open the Simple Custom CSS and JS snippet list. Open each snippet and copy the code content.
- Create snippets in Simple Custom Code — For each code block, create a new snippet with the correct type (CSS, JS, HTML), placement (head/footer), and location (frontend / admin / login, etc.).
- Activate your new snippets — Use the one-click toggle to enable each snippet and verify everything works correctly on the frontend and admin.
- Deactivate Simple Custom CSS and JS — Once all snippets are confirmed working, deactivate and uninstall the old plugin.
- Optional: Upgrade to Pro — If you need page-specific loading conditions, minification, SCSS/Less, or shortcode loading, upgrade to Simple Custom Code Pro from $11.60/year.
Frequently Asked Questions
-
Is Simple Custom CSS and JS free?
Yes. Simple Custom CSS and JS has a free version on the WordPress plugin repository with over 700,000 active installations. A paid Pro version is available at silkypress.com, starting at $48.50 for 1 site (one-time payment including 1 year of updates).
-
What is the best alternative to Simple Custom CSS and JS?
Simple Custom Code is a strong modern alternative. The free version includes more features — AI-powered code generation, a real-time visual CSS editor, smart error detection, autocomplete, and multiple editor themes. Its Pro tier starts at $11.60/year, significantly more affordable than Simple Custom CSS and JS Pro.
-
Does Simple Custom Code fully replace Simple Custom CSS and JS?
For most users, yes. Simple Custom Code covers all core use cases and adds significant modern tooling on top. The main features not yet in Simple Custom Code are code revision history, shareable preview URLs, and snippet export/import — all Pro-only in Simple Custom CSS and JS and planned for future Simple Custom Code releases.
-
Is Simple Custom Code free?
Yes. Simple Custom Code has a permanently free version available on WordPress.org that includes unlimited snippets, file-based storage, AI code generation, a real-time visual CSS editor, error detection, a code beautifier, and more. A Pro version is available from $11.60/year.
-
Will I lose my snippets if I switch?
No. Your snippets stored in Simple Custom CSS and JS remain in your WordPress database until you uninstall the old plugin. You will need to manually copy your code into Simple Custom Code snippets — for most sites this takes only a few minutes. Your theme, content, and settings are unaffected.

Yes. Simple Custom Code is fully theme-independent and works with all major WordPress page builders including Elementor, Divi, Beaver Builder, Bricks Builder, and Gutenberg.

How does storage differ between the two plugins?
Both plugins use file-based storage — your code is not loaded from the database at runtime. The practical difference on storage between the two is minimal. Where Simple Custom Code pulls further ahead is in Pro-tier optimizations: cache mode combines all active snippets per page into a single file, and automatic minification reduces file sizes. Neither optimization is available in Simple Custom CSS and JS Pro.
-
Is Simple Custom Code Pro worth it compared to Simple Custom CSS and JS Pro?
For most users, yes. Simple Custom Code Pro costs significantly less — from $11.60/year vs $48.50 for 1 site — and includes features Simple Custom CSS and JS Pro lacks: cache mode, HTTP request reduction, source comment removal, optimized loading, and manual loading via WordPress hooks. The main advantage Simple Custom CSS and JS Pro retains is revision history and shareable preview URLs, genuinely useful for client-approval agency workflows.
