Why Muleline

Built for reliability, not complexity

A sync engine with AI built in. Move files, recognize faces, search with natural language — all from one Python package.

🔒

SHA-256 Deduplication

Never store the same file twice. Content-addressed storage means identical files from any device get deduplicated automatically, saving space and bandwidth.

▶

Chunked Resumable Uploads

TUS-inspired protocol with 5MB chunks. Lose your connection mid-upload? Resume exactly where you left off. Works over flaky mobile networks without retrying from zero.

📈

Manifest Diff Sync

Client sends file hashes, server returns precisely what needs uploading or downloading. No full scans. Multi-device sync state tracked per device_id.

📦

Pluggable Storage Backends

Local filesystem out of the box. S3, Cloudflare R2, MinIO with pip install muleline[s3]. Or implement StorageBackend for your NAS, WebDAV, or anything else.

🔨

Mount in 3 Lines

Muleline is a FastAPI router. Mount it inside any existing FastAPI app and your sync API is live immediately. No separate service, no new infra to manage.

⚡

SQLite Only

No Redis, no Postgres. Sync state, upload sessions, device registry, and activity logs all live in a single SQLite WAL database. Run it with a single volume mount.

Connect your storage. Keep your files. Muleline works with your existing infrastructure.

Quick Start

Up in under a minute

Install, wire into your FastAPI app, and every /sync/* endpoint is live.

main.py python

# pip install muleline[server]

from fastapi import FastAPI
from muleline.engine import SyncEngine
from muleline.storage import LocalStorage
from muleline.db import run_migrations
import muleline.router as sync_router

app = FastAPI()

# Initialize
run_migrations()
engine = SyncEngine(storage=LocalStorage("./data/uploads"))
sync_router.init(engine)

# Mount — all endpoints live at /sync/*
app.include_router(sync_router.router)

Intelligence

AI that works for your photos

Every upload gets smarter. No manual tagging required.

🧠

Auto-Classification

Gemini Vision categorizes every photo on upload — landscapes, food, people, screenshots, documents. Requires a Gemini API key.

👥

Face Recognition

dlib-powered face detection with numpy embeddings and sklearn clustering. Scans on upload, groups by person.

🔎

Smart Search

Search your entire library with natural language. "sunset at the beach" or "birthday cake" just works.
