ProtonDB Steam Deck & Linux Compatibility Scraper

Fetch crowd-sourced Linux and Steam Deck compatibility ratings from ProtonDB for any list of Steam game IDs. Returns compatibility tier, trending tier, confidence level, aggregated score, and report count per game — joinable with the Steam catalog for a complete Deck-readiness dataset.

Features

• Fetch ProtonDB compatibility data for any list of Steam App IDs
• Returns tier (native, platinum, gold, silver, bronze, borked, pending), best reported tier, trending tier, confidence level, score (0–1), and total report count
• Built-in default set of 15 popular games — works out of the box with no configuration
• Accepts your own App ID list for targeted lookups (single game or thousands)
• Lightweight pure-API actor — no browser, fast and low cost
• Each record is joinable with Steam catalog data by steam_appid

Input

Field	Type	Default	Description
appIds	integer[]	15 built-in popular games	List of Steam App IDs to look up. Find an App ID in the Steam store page URL (e.g. store.steampowered.com/app/440/ → 440).
maxItems	integer	10	Maximum number of records to return.

Leave appIds empty to use the built-in default set covering a representative range of compatibility tiers.

Each record maps to one Steam game:
