Setting up Seed Sniffer
Seed Sniffer is a small tool that reads the map seed of your current server from the game log while you play and sends it to this browser. There’s nothing to configure. Download it, run it, and it pairs with this browser automatically.
- 01
Download
Get Seed Sniffer with the button below. The download already carries the pairing code that links it to this browser. On Linux, the same button gives you the .sh version.
- 02
Run it
On Windows, run the downloaded file. Because it is an unsigned script, Windows or your antivirus may show a warning; choose “More info → Run anyway,” or Keep, to continue. On Linux, see the section below.
- 03
It pairs automatically
Once running, it links to this browser right away using the code baked into the download. The tool shows its link status, and the sidebar indicator switches to “Receiving.”
- 04
Join a game → the map appears
When you join an SCP:SL server, its seed is detected and that map opens in this browser on its own. When a new round changes the seed, the map updates to match.
Something not working?
If a warning deleted the file, download again and choose Keep. If nothing is detected, check that you have joined a game and that the browser’s link status reads “Receiving.” An outdated build will prompt you to update.
Linux (Steam Proton, Steam Deck)
The Linux version is a bash script, scpsl-seed-detector.sh, for SCP:SL running through Steam Proton, including Steam Deck in desktop mode. Run it in a terminal with the command below. The first run opens the same short setup as on Windows (language, hotkey, auto key press, push, notifications). It works the same way too: it binds a key (F8 by default) to the game’s built-in seed command, reads the seed from the game log and sends it to the site, without touching game memory or network traffic. Pairing with the browser and updates happen automatically.
bash scpsl-seed-detector.shTrouble on Linux?
It finds the game’s Proton folder on its own. If it can’t, set the SCPSL_PREFIX environment variable to the Proton pfx folder. Automatic key presses need xdotool (X11 or XWayland). Without xdotool, press the key (F8 by default) in game yourself.
