## What it is
Blossom is a self-hosted markdown note-taking application with bidirectional links, built-in image hosting, and real-time device synchronization. It also includes productivity extras like todo lists, plans, pomodoro timer, and a dynamic blog.

## Use cases
- self-host a markdown note app with cloud sync
- keep notes and images on my own server
- sync notes across devices privately
- write markdown notes with backlinks
- host a personal blog from my notes
- replace Notion/Obsidian sync with self-hosted storage

## When to choose
- you want full ownership of your notes and images on your own server
- you need cross-device real-time sync without third-party cloud
- you want an integrated editor, image hosting, and blog

## When to avoid
- you only need a lightweight local markdown editor without sync
- you prefer plain-file storage in a git repo like Obsidian vaults
- you need offline-first desktop-only editing without a server

## Facets
- artifact type: application
- maturity: active
- function: editor, markdown, file-upload, self-hosted, documentation
- domain: developer-tools, text-editors, self-hosted, web-development, documentation
