fx

fx is a compact, self-hostable microblogging and blogging server written in Rust. It focuses on quick publishing and editing of Markdown posts with a small runtime footprint and simple administration.

Key Features

• Lightweight Rust server designed to run with minimal memory and disk usage
• Write posts in Markdown with built-in syntax highlighting
• Inline math support using LaTeX-style syntax
• Upload files and images for embedding in posts
• Built-in search for finding posts
• Follow RSS feeds via a blogroll/follow list
• Simple backup API that exports site data as plain-text archives
• Docker and Docker Compose friendly; stores data in a local SQLite database
• API endpoints for basic site management and automated backups

Use Cases

• Personal public notebook for quick notes, recipes, code snippets, or micro-blogs
• Teacher or support knowledge base for reusable answers and shareable links
• Lightweight publishing platform for POSSE-style syndication to external social platforms

Limitations and Considerations

• No built-in federation (ActivityPub) or distributed social networking support, so it does not natively interoperate with Mastodon/Bluesky networks
• Designed primarily as a single-site, single-account blogging service with a SQLite backend; not intended for high-scale multi-user installations

fx is aimed at users who want a minimal, fast place to publish and retrieve short-form content without the complexity of larger platforms. Its small footprint and simple backup/export options make it suitable for personal sites and small deployments.
