Steam Sales & Discount Tracker

Track every discount on Steam in one actor:

• All ~9,500 items on sale right now, with the exact time each discount ends and what kind of deal it is.
• The storefront's Daily Deal, Weekend Deals, Free Weekends and publisher/franchise sales.
• Free-to-keep giveaways.
• Regional prices converted to USD.
• Every item on a sale page.
• Steam's official calendar of seasonal sales and Fests.

Schedule it (for example every 6 hours) and each record also tells you how the price changed since the previous run. It also flags new deals and the lowest price seen so far, and lists deals that ended.

The same kind of record on a scheduled run, after a price drop:

{
    "recordType": "DEAL",
    "name": "Japanese Ramen Simulator",
    "finalPriceCents": 1274,
    "previousFinalPriceCents": 1774,
    "priceChangeCents": -500,
    "priceDropPct": 28.2,
    "isNewDeal": false,
    "lowestPriceSeenCents": 1274,
    "isLowestPriceSeen": true,
    "alert": true
}

An APP_PRICE record:

{
    "recordType": "APP_PRICE",
    "name": "Risk of Rain 2",
    "country": "ID",
    "currency": "IDR",
    "finalPrice": 39599.0,
    "discountPct": 67,
    "finalPriceUsd": 2.21,
    "usdRank": 1,
    "vsUsPricePct": -73.2,
    "cheapestCountry": "ID",
    "discountEndsAt": "2026-10-22T17:00:00Z"
}

A SALE_EVENT record:

{
    "recordType": "SALE_EVENT",
    "eventType": "seasonal_sale",
    "name": "Winter Sale 2026",
    "startDate": "2026-12-17",
    "endDate": "2027-01-04",
    "status": "upcoming",
    "daysUntilStart": 67,
    "durationDays": 18
}

Record types: DEAL, DAILY_DEAL, SPOTLIGHT, FEATURED_SPECIAL, FREEBIE, APP_PRICE, SALE_PAGE, SALE_ITEM, SALE_EVENT, DEAL_ENDED, ERROR. Each record has _input, _source (which endpoint produced it) and _scrapedAt. Prices come as both amounts (finalPrice) and Steam's integer cents (finalPriceCents).

Monitoring (change detection)

With Compare with previous run on (default), the actor remembers every item's price per task and adds:

• previousFinalPriceCents, priceChangeCents, priceDropPct. These show the change since the last run.
• isNewDeal: the item is discounted now but was not discounted (or not listed) last time.
• lowestPriceSeenCents, lowestPriceSeenAt, isLowestPriceSeen: the lowest price this task has ever recorded for the item.
• alert: a new deal, or a drop of at least Price-drop alert threshold.
• DEAL_ENDED records (in deals and freebies mode): items that were on sale last run and are gone now.

Snapshots are kept per mode and per filter set in the named key-value store steam-sales-tracker-snapshots, so tasks for different countries or tags never interfere. Ended deals are only reported after a run that read the whole result list. If maxItems cut the list short, that check is skipped, because a missing item could just be beyond the cut.

Good to know

• Prices are regional. Steam runs different discounts per country (the US had 9,463 deals and Indonesia 9,593 on the same day), so country decides both the list and the currency. Prices follow the country setting, not the proxy location.
• Seasonal sales and Fests build their pages dynamically, so salePage cannot list their items. Use deals with the Fest's tag instead (for example "tags": ["Cooking"] during the Cooking Fest). Use saleEvents to know when they start.
• minDiscount and maxPrice are applied after download, because Steam has no discount filter. They don't reduce how many pages are read.
• About 2% of Steam's specials list is shown at 0%. These are edition upgrades, and DLC whose bundle is what's discounted. They are dropped by default (minDiscount: 1). Set minDiscount: 0 to keep them; discountedPurchaseOptions then shows where the discount actually is.
• Free Weekend records show the game's discount end, if it is also on sale. Steam does not publish the free-play window's end time in machine-readable form.
• sortBy: reviewsDesc only lists reviewed items (about half of all deals). That's Steam's behaviour.
• USD conversion uses the European Central Bank's daily reference rates (about 30 currencies). Prices in other currencies keep finalPriceUsd: null.
• Unknown sale pages, appids and tag names come back as ERROR records with a clear reason. They never produce empty or made-up data.

Technical notes

• No WAF, no login, no browser. Every endpoint is public: Steam store search, api/featuredcategories, api/appdetails, the sale pages, Steamworks' public "Upcoming Steam Events" page, and Valve's official keyless store API (IStoreBrowseService/GetItems) for discount end dates and deal types. HTTP only (curl_cffi, Chrome TLS profile; it rotates through a profile ladder if a gate ever appears).
• The one limit is per IP on store search: about 40 quick requests, then HTTP 429 for ~20 seconds. The actor paces search to one request every 2.5 seconds. With a proxy, a 429 switches to a new exit IP; without one, it waits the lockout out. A full 9,500-deal crawl takes about 5 minutes.
• Pagination: 100 items per page (Steam's maximum), read to the true end of the list.
• Completeness:
  • Steam's default "relevance" order keeps re-sorting during a long walk. In testing, a full walk in that order saw only 9,153 of 9,463 items, and price order loses ~0.6% to ties.
  • So a run that asks for the whole list (maxItems ≥ the number of deals) walks it in name order, which saw 9,463 of 9,463. sortOrder on each record tells you which order position refers to.
  • The actor measures coverage on every run. Ended deals are only reported when at least 99.8% of the list was seen.
• Silent traps handled:
  • An unknown country makes appdetails fall back to USD and search return 0, so country codes are validated up front.
  • Ended sale pages redirect to the homepage with HTTP 200 and are detected.
  • Unknown sort_by and category1 values are ignored by Steam, so input values are restricted to the honoured ones.
  • Bundle-owner discounts carry two different prices in the page, and the displayed one is used.
• Proxy: Apify Residential is pre-selected. Datacenter or no proxy also works, just slower on very large crawls.
