CodesKeep — Google Keep for Developers CodesKeep is the note-taking app built specifically for developers who live in code. If you've ever pasted a SQL query into Google Keep and watched it turn into an unreadable wall of gray text, you already know why CodesKeep exists.
Markdown & Syntax Highlighting, Finally. Write your notes in full GitHub Flavored Markdown with live rendering. CodesKeep supports syntax highlighting for 12+ programming languages — JavaScript, Python, Rust, Go, SQL, Java, C++, PHP, HTML, CSS, and more — all powered by CodeMirror 6. Your code looks like code: colored, indented, and instantly readable. The split-view editor lets you type Markdown on one side and see the rendered output on the other in real time.
Built on the Google Ecosystem You Already Use. No new account to create. No new password to remember. CodesKeep integrates seamlessly with Google Workspace — sign in with your existing Google account and you're ready to go. Your notes sync instantly across all your devices via Firestore, so you're always working with the latest version whether you're on your laptop, tablet, or phone.
Your Data Stays Yours. Every note is automatically backed up to your own Google Drive in both JSON and PDF formats. JSON for programmatic access and re-importing; PDF for sharing with teammates or archiving. You keep full control over your data at all times — no vendor lock-in, no proprietary formats. If CodesKeep ever goes down, your notes are still sitting safely in your Drive.
Designed for Real Developer Workflows. Organize notes with color-coded labels, folders, tags, and pinning. Search across all your notes instantly. Archive what you don't need right now without deleting it. Whether you're saving API documentation, debugging journals, deployment runbooks, or quick code snippets, CodesKeep keeps everything structured and accessible.
