# Siftlode

**Your YouTube subscriptions, the way a feed should work.** Siftlode pulls every upload from the
channels you follow into one clean, filterable feed — no algorithm deciding what you see, and no
Shorts or livestream noise unless you want it. Self-hosted, multi-user, and private: your data
stays on your own server.

Everything expensive (channels, videos, metadata) is fetched from YouTube once and stored locally,
so filtering, searching and sorting are instant and don't burn API quota. Click a video to watch it
in an in-app player that resumes where you left off — or open it on youtube.com so your own ad
blocker and SponsorBlock keep working.

## Features

- **A readable subscription feed** — sort and filter by channel, tag, language, topic, length,
  upload date or watch state; hide channels without unsubscribing; save filter setups as named views.
- **Search all of YouTube** from the feed — results play, save and add to playlists like any other
  video, and are materialised into your catalog.
- **Channel pages & a channel manager** — per-channel stats and uploads, priorities, and your own
  tags to slice the feed by.
- **Playlists with two-way YouTube sync** — build them locally, keep them in sync in both directions.
- **In-app player** with resume, plus keyboard/scroll controls.
- **Download Center** — save videos to the server with yt-dlp in a Plex-friendly layout (format
  presets, per-user storage quota), trim / crop / split & join them in a built-in editor, then save
  to your device, share with another user, or hand out a public watch link.
- **Multi-user** with per-user private state, a shared catalog, and a fair daily API-quota guard.
- **Self-hosted & private**, with a first-run web setup wizard and the interface in **English
  and Hungarian**.

## Quick start (self-hosting)

You don't need to build anything — Siftlode runs from a prebuilt public image, and all
configuration (your admin account, Google sign-in, email) happens in a **first-run web wizard**.
You need [Docker](https://docs.docker.com/get-docker/) with the Compose plugin.

**1. Get the files and run the installer:**

```sh
git clone https://forge.b1fr0st.eu/peter/siftlode.git
cd siftlode
./install.sh          # Windows (PowerShell):  ./install.ps1
```

The installer generates a private `.env` (secrets), pulls the image, starts the app + database, and
prints a one-time setup URL like `http://localhost:8080/setup?token=…`.

**2. Finish in your browser.** Open that URL and follow the wizard:

1. **Admin account** — the email + password you'll sign in with.
2. **Google sign-in** *(optional)* — paste a Google OAuth client to enable "Sign in with Google" and
   pulling your YouTube subscriptions. Skip it to use email + password only.
3. **Email / SMTP** *(optional)* — for verification/notification emails. Skip it and you (the admin)
   simply approve new accounts yourself.

Then sign in with your admin account. That's it. See **[docs/self-hosting.md](docs/self-hosting.md)**
for the full walkthrough.

> Just trying it out? Press Enter at the installer's URL prompt to run on `http://localhost:8080`.

## Build from source (alternative)

Prefer to build the image yourself instead of pulling it:

```sh
git clone https://forge.b1fr0st.eu/peter/siftlode.git
cd siftlode
cp .env.example .env
# generate the two secrets and paste them into .env:
python -c "import secrets;print('SECRET_KEY='+secrets.token_urlsafe(48))"
python -c "import base64,os;print('TOKEN_ENCRYPTION_KEY='+base64.urlsafe_b64encode(os.urandom(32)).decode())"
docker compose up --build -d      # builds from the included Dockerfile
```

Open `http://localhost:8080` and finish in the setup wizard as above. (Set a `POSTGRES_PASSWORD` in
`.env` too.)

## HTTPS / public access

Port `8080` over plain HTTP is fine for a LAN or a quick trial. For public access put a reverse
proxy (Caddy, Nginx, Traefik…) in front to terminate TLS, and set the **public URL** (the installer
prompt, or `OAUTH_REDIRECT_URL` in `.env`) to your `https://…` address — this also marks the session
cookie secure. Add that same `…/auth/callback` URL to your Google OAuth client's authorized redirect
URIs. Behind a proxy, also set `TRUSTED_PROXY_IPS` so the rate limiters see the real client IP and
can't be bypassed via a forged `X-Forwarded-For` — see [docs/self-hosting.md](docs/self-hosting.md#https--public-access).

## Updating & backups

```sh
docker compose -f docker-compose.selfhost.yml pull   # or: docker compose pull
docker compose -f docker-compose.selfhost.yml up -d
```

Database migrations run automatically on startup. Your data (accounts, subscriptions, playlists, the
video catalog) lives in a Postgres volume — back it up with `scripts/backup.sh` (or `backup.ps1` on
Windows) and restore with `scripts/restore.sh`.

## How it works

- **Shared catalog, private state.** Channels and videos are stored once and shared; each user's
  subscriptions, tags, playlists and watch/save/hide state are private.
- **Cheap by design.** Public reads are cached locally; a shared daily quota budget and a background
  scheduler keep unattended syncing within YouTube's free API limits. An optional API key lets
  backfill run without depending on a user's OAuth token.
