SEC-12: the download box accepts an arbitrary http(s) URL and yt-dlp fetches it from the WORKER, so any approved user could aim the server at the compose network, the LAN or a cloud metadata endpoint — and read the result off job.error, where "connection refused" vs "HTTP Error 401" vs "timed out" is a port scanner. downloads/urlguard.py refuses a URL whose host resolves to a loopback/private/link-local/reserved address, at enqueue AND again in the worker (DNS can move in between, and the worker is where the socket opens). A network-class failure on a `url` job now reports one fixed sentence instead of the raw transport text; the error CODE is still classified from the original, so the localized explanation is unchanged. DNS rebinding is explicitly NOT closed — that needs the connection gated inside yt-dlp — and the module says so rather than implying more than it does. SEC-13: `noplaylist` only demotes a video-inside-a-playlist URL to that video, so a URL that is purely a playlist or channel still expanded into every entry — one enqueue, unbounded downloads. `playlist_items` pins it to one. Size was unbounded too: `check_enqueue` compares the CURRENT footprint against the cap, and a download's size is unknown until it lands, so one job could overshoot by any amount; the owner's remaining budget is now handed to yt-dlp as `max_filesize`, applied AFTER the adapter merge so no source adapter can raise a limit the quota layer set. A join's cut-list is capped at 100: an accurate join emits two filters per segment into one ffmpeg filter_complex. SEC-14: the YouTube budget is instance-wide, so one user holding down a manual sync spent the day for everyone. Per-user (not per-IP — the cost belongs to the account) 3-per-10-minutes limiters on the two bulk pulls, subscriptions and playlists, with separate budgets so one does not close the other. The review also listed /rss, /backfill and /enrich; E3 deleted them, and search stays unlimited on purpose — it is interactive, not a bulk pull. Gate: pytest 896 -> 924 (none skipped), vitest 671.
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 — live results you can play, save or add to playlists like any other video; they stay temporary and out of your catalog unless you keep one.
- 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.
- Plex library (optional) — point Siftlode at your own Plex server to browse and play its movies and shows alongside your feed, with watch state kept in sync.
- 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 with the Compose plugin.
1. Get the files and run the installer:
git clone https://git.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:
- Admin account — the email + password you'll sign in with.
- 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.
- 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 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:
git clone https://git.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.
Updating & backups
docker compose -f docker-compose.selfhost.yml pull # or: docker compose pull
docker compose -f docker-compose.selfhost.yml up -d
That follows latest, which moves with every release. Set IMAGE_TAG=0.80.0 in .env to pin a
version and upgrade on your own schedule; released versions are listed in CHANGELOG.md
and in the app's Release Notes.
Back up before upgrading. Migrations run automatically on startup and are not undone by pulling
the old image back. A backup is the database dump plus your .env — TOKEN_ENCRYPTION_KEY is
what decrypts the Google, SMTP and Plex secrets stored in that database, so a dump restored without it
is only half an instance. Use scripts/backup.sh (or backup.ps1 on Windows) and scripts/restore.sh;
the equivalent one-liners, the pinning recipe and the rollback steps are in
docs/self-hosting.md.
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.
