Chiyogami

Chiyogami is a modern, self-hosted pastebin that provides encrypted and unencrypted pastes, user accounts, configurable expirations and a REST API for programmatic use. It combines a Go-based backend with a responsive JavaScript frontend and is distributed as a Docker image for easy deployment.

Key Features

• Client-side encryption using the WebCrypto API for encrypted pastes; server does not store user passwords.
• Configurable paste expiration (hours, days, never) and visibility modes: Public, Unlisted, Private.
• User accounts and session-based paste ownership with endpoints for create, fetch, delete and instance info.
• Syntax highlighting and Markdown rendering in the browser (uses HighlightJS and Marked for formatting).
• Lightweight SQLite storage and built-in rate limiting to mitigate abuse.
• Docker-ready distribution and example docker-compose; optional pre-built container image available.

Use Cases

• Share code snippets or notes with configurable lifetime and optional client-side encryption.
• Provide a small internal or team paste service for temporary file/text sharing behind a reverse proxy.
• Integrate creation and retrieval of short-lived pastes into scripts, CI jobs or automation via the REST API.

Limitations and Considerations

• Client-side encryption depends on the browser WebCrypto implementation; losing the encryption key/password may render encrypted pastes unrecoverable.
• Uses SQLite for storage which is suitable for small-to-medium deployments but may be a scaling constraint for high-volume instances.
• The README notes a /health endpoint that should be protected when exposed publicly to avoid information disclosure or abuse.

Chiyogami is a compact, developer-focused pastebin designed for easy self-hosting, quick sharing and scriptable workflows. It emphasizes privacy via client-side encryption and simple deployment via Docker.
