About Code Injection
SuperDev Pro's Code Injection runs your own JavaScript, CSS, and HTML against any page, with per-domain snippet libraries so the right code only loads where you want it.
Great for tweaking client sites in real time, building one-off fixes, or testing UI ideas without touching the source.
Key Features
- Three language tabs: JavaScript, CSS, and HTML with sensible placeholders
- Live injection — no page reload required to see changes
- Save snippets per-domain with their own library on every host
- Saved snippet list with apply, remove, and delete actions
- Active-snippet badge so you can see what is currently running
- Disable or pause injections without losing your drafts
- Per-origin namespacing keeps snippets scoped to the right site
- Debounced auto-save so drafts survive accidental closes
- Error reporting for syntax and runtime failures
- Re-apply saved snippets across sessions with one click
