Self-Hosted Stremio Stack

A high-performance, self-hosted backend for Stremio with Real-Debrid. Uses Comet as the addon, Jackett for indexer management, PostgreSQL for persistent caching, and built-in scrapers (Torrentio, Zilean) for maximum content coverage.

Features

• Fast: Background scraper pre-caches popular content. Most searches resolve from local cache in under 3 seconds.
• Secure: No ports exposed by default. PostgreSQL isolated in an internal network with no internet access.
• Multi-source: Three scraping layers (Jackett indexers + Torrentio + Zilean) working together for broad coverage.
• Smart caching: PostgreSQL stores torrent metadata permanently. Repeated searches are instant.
• Captcha bypass: FlareSolverr included for Cloudflare-protected indexers (like 1337x).

Prerequisites

• Docker & Docker Compose installed.
• Real-Debrid API Key.
• (Optional) A reverse proxy (Caddy, Nginx, Traefik) or Tailscale for external access.

Deployment

1. Clone and Configure

git clone https://github.com/ImJustDoingMyPart/stremio-stack.git
cd stremio-stack
cp .env.example .env

Edit .env with your settings. You'll need to start the stack once to get the Jackett API Key, then update .env and restart.

2. Create the proxy network

If you don't already have a shared proxy network:

docker network create proxy_net

If you use Caddy or another reverse proxy, connect it to this same network.

3. Start the Stack

docker compose up -d

4. Configure Jackett

1. Access Jackett (via your proxy or http://YOUR-IP:9117 if ports are uncommented).
2. Set FlareSolverr URL in Settings: http://flaresolverr:8191
3. Add indexers. Recommended starting set:
   • General: 1337x, The Pirate Bay, TheRARBG, TorrentGalaxyClone, EZTV, YTS, Knaben, LimeTorrents
   • Anime: Anime Tosho
   • Spanish content: MejorTorrent, DonTorrent
4. Copy the API Key from Jackett's top-right corner into your .env file.
5. Restart Comet: docker compose restart comet

Tip: Avoid adding too many indexers. 8-12 well-chosen ones beat 50 slow ones. The INDEXER_MANAGER_TIMEOUT (default 12s) will drop slow indexers from results automatically.

5. Configure Comet

1. Access the Comet configuration page (/configure).
2. Enter your Real-Debrid API Key.
3. Enable Show Cached Only for a clean streaming experience.
4. Click Install to add it to Stremio.

• proxy_net: External network with internet access. Connects to your reverse proxy.
• internal: Isolated network. PostgreSQL lives here with no internet access.
• Comet, Jackett, and FlareSolverr bridge both networks.

How It Works

Comet pulls torrents from three sources simultaneously:

Source	Type	Speed	Coverage
Jackett	Your configured indexers	Depends on indexer	Customizable
Torrentio	Pre-crawled database	Fast	Massive (mainstream)
Zilean	DMM hashlist index	Fast	Large (debrid-focused)

The background scraper runs every hour, pre-caching results from all three sources into PostgreSQL. When you search in Stremio, Comet checks the local cache first — if it's fresh enough, you get results in under a second without waiting for any external query.

Content you search manually gets demand priority, so it stays fresh in the cache for longer.

Subtitles

Subtitles in Stremio are handled by separate subtitle addons, completely independent from this stack. Comet only provides the video stream.

Recommended: Install the OpenSubtitles v3 addon in Stremio. It matches subtitles by IMDB ID and works with any stream source, including self-hosted instances.

Note for self-hosted instances: Hash-based subtitle addons (like Subhero) may not work with self-hosted Comet if your instance is only accessible via a private URL (e.g., Tailscale). These services need to reach the stream URL from the internet to compute the file hash. OpenSubtitles v3 has no such requirement and is the reliable choice.

Chromecast / Android TV / iOS

Stremio on these devices requires HTTPS. The easiest way without opening router ports is Tailscale Serve:

# Expose Comet privately to your Tailnet
tailscale serve --bg --https=443 http://localhost:8000

Use the generated URL (e.g., https://my-server.tailnet.ts.net) as your PUBLIC_BASE_URL in .env, restart, and reconfigure the addon.

Serve = private to your Tailnet (recommended). Funnel = public internet.

Performance Tuning

All performance variables have sensible defaults in docker-compose.yml. Override them in .env only if needed:

Variable	Default	Description
FASTAPI_WORKERS	2	Gunicorn workers (increase for high concurrency)
INDEXER_MANAGER_TIMEOUT	12s	Max wait per Jackett indexer
BACKGROUND_SCRAPER_ENABLED	True	Pre-cache popular content
BACKGROUND_SCRAPER_CONCURRENT_WORKERS	2	Parallel scraping workers
SCRAPE_JACKETT	both	Jackett scraping mode
SCRAPE_TORRENTIO	both	Torrentio scraping mode
SCRAPE_ZILEAN	both	Zilean scraping mode
TORRENT_CACHE_TTL	-1	Torrent cache lifetime (-1 = permanent)
LIVE_TORRENT_CACHE_TTL	86400	Seconds before triggering a fresh search
DEBRID_CACHE_TTL	86400	Debrid availability cache (1 day)

Scraper modes: live (on-demand only), background (pre-cache only), both, false (disabled).
