A video too large for Discord, a secret that should not live in a chat log, or a config file a headless server needs to fetch: MicroBin turns each into a short link with an animal name, served from your own machine. Paste text or code and it comes back with syntax highlighting, inline image and video embedding, and a QR code for moving it to a phone. Attach one file or several, then decide exactly who can see them: uploads can be public or private, editable or locked, set to expire on a schedule or to never expire. For sensitive material, server-side encryption and client-side end-to-end encryption keep contents unreadable without the password. Raw serving hands the plain bytes to curl, a browser, or another program, which makes the same box a tiny file endpoint for scripts and test rigs. A postbox mode lets people send you files and texts they cannot browse or delete afterwards, and a read-only mode with an uploader password turns the instance into a drop point with exactly one trusted sender. The admin console lists uploads and storage, and everything runs as one small binary backed by SQLite or a JSON file, comfortable in a few megabytes of memory.
