A free online code snippet manager to help developers save and organize frequently used code. Create categories, add tags, highlight syntax, and find anything instantly with full-text search. All data stored in browser localStorage with JSON export for backup.
All code snippet data is stored in your browser's localStorage and never uploaded to any server. You have complete control. Data persists after closing the page, but clearing browser cache will delete it. We recommend regular JSON exports for backup.
Browser localStorage typically has 5-10MB of space. With each snippet averaging 1-5KB, you can save approximately 1000-5000 snippets. Export and clean up old snippets when approaching the limit.
Click 'Export JSON' to download all snippets as a JSON file. To restore, use 'Import JSON' to select your backup file. This is the primary way to migrate and backup your data.
Supports syntax highlighting for 30+ languages: JavaScript, TypeScript, Python, HTML, CSS, Java, C++, C#, PHP, Ruby, Go, Rust, SQL, Swift, Kotlin, Bash, YAML, JSON, Markdown, and more.
Yes! Each snippet can have multiple tags for easy categorization and search. For example, a 'React Hooks' snippet could have tags like 'react', 'hooks', and 'frontend'. Both English and Chinese tags are supported.
No. Data is stored in localStorage and persists even after closing the browser or restarting your computer. Note: using private/incognito mode will clear localStorage when the last tab is closed.
