Code Manager

あらゆるウェブページでコードブロックをコピー、ナビゲート、折りたたみ、番号付けできます。ワンクリックコピー、自動行番号など。

Code Manager adds a powerful toolbar to every code block on any webpage — so you can copy, navigate, collapse and number code instantly. WHAT IT DOES Every time you visit a page with code blocks, Code Manager automatically: ✅ Adds a header bar to every code block ✅ Numbers every line automatically ✅ Shows the programming language ✅ Shows the line count ✅ Lets you copy any block with one click ✅ Lets you copy ALL blocks at once with labels and titles ✅ Lets you collapse and expand any block ✅ Lets you navigate between blocks with prev / next buttons ✅ Lets you scroll to the top or bottom of any block ✅ Shows a notification bar after every action ✅ Counts every action in the popup badge PERFECT FOR 👨‍💻 Developers reading documentation 📚 Students following tutorials 🧑‍🏫 Teachers sharing code examples 🔬 Researchers collecting code snippets 📝 Writers copying code into articles WORKS ON • Any webpage with code blocks ONE-CLICK COPY Every code block gets a copy button. Click it and the code goes straight to your clipboard — no selecting, no dragging, no right-clicking. COPY ALL BLOCKS One button copies every visible code block on the page at once. Each block is labelled with its number, language, line count and the nearest heading — so you always know where each snippet came from. LINE NUMBERS Line numbers are added automatically to every code block. They are not included when you copy — only the clean code goes to your clipboard. COLLAPSE AND EXPAND Long code blocks can be collapsed to a single header bar so they do not take up space while you read. Click again to expand. BLOCK NAVIGATOR For long code blocks, scroll-to-top and scroll-to-bottom buttons appear so you never lose your place. Prev and next buttons let you jump between all code blocks on the page. NOTIFICATION BAR A slim notification bar slides in at the top of the page after every action — copy, copy all, collapse, expand or navigate — with a clear message and a quick link to support the developer. ACTION COUNTER The popup badge counts every action you perform. Open the popup to see your total at a glance. PRIVACY Code Manager does not collect, store or transmit any personal data. All data stays on your device. No accounts, no tracking, no analytics.
