Pastefy

Pastefy is an open-source, self-hostable Pastebin-style application for sharing and storing code snippets, text files, and lightweight media previews. It provides a web UI and a RESTful API for creating, forking, organizing and retrieving pastes.

Key Features

• Web UI built with Vue and a Java-based backend for creating, forking and managing pastes
• REST API for programmatic paste creation, retrieval and client integrations
• OAuth2 login providers support (multiple providers and custom OIDC configuration)
• Folder and user paste management with admin panel for site administration
• Raw preview, copy button, syntax-aware previews for Markdown, Mermaid, SVG, CSV, GeoJSON, diffs and asciinema recordings
• File upload support and curl-compatible upload endpoint
• Extensions and client libraries (Java, Go, JavaScript/TypeScript) and editor integrations

Use Cases

• Quickly share code snippets, config files or logs with teammates or public audiences
• Store and replay terminal recordings or structured data (asciinema, GeoJSON, CSV) for troubleshooting and demos
• Integrate paste creation into developer tools, CI scripts or editor extensions via the REST API

Limitations and Considerations

• Backend is JVM-based and typically deployed with Maven/Java; requires a Java runtime and a relational database (MySQL commonly used)
• Admin role assignment may require direct database changes for initial setup as noted in administration instructions
• Authentication is primarily OAuth/OIDC based; enterprise directory integrations beyond OAuth may require custom configuration

Pastefy is suitable for teams and individuals who need a lightweight, extensible paste service with API access and rich previews. It balances a modern web frontend with a Java backend and supports common deployment patterns including Docker and Docker Compose.
