Methodology

How we score, why our rankings can be trusted.

Every tool on cs2apps.com is hand-tested by a real CS2 trader against the criteria below. No paid placements, no scraped reviews, no algorithmic shortcuts. This page documents the exact rubric, the re-verification cadence, and what triggers a re-rank.

The five criteria we score on

Every criterion is scored 1–5 against what we observed during testing, then weighted into the final rank for the tool’s primary category.

• Breadth of CS2 coverage

  weight 25%

  How much of the CS2 economy the tool covers — every active case, every relevant marketplace, every pattern family, every skin family. Specialists score high if their niche is what the user is hunting.

• Data accuracy & freshness

  weight 25%

  Does the price match what's quoted on the source marketplaces right now? Are stale listings filtered out? When the tool publishes a number, can we reproduce it against the primary source?

• UX and usability

  weight 20%

  Can a CS2 trader get the answer they came for in under 30 seconds? Mobile responsive? Reasonable defaults? No paywalls in front of basic information that should be free?

• Public API or programmatic access

  weight 15%

  Is there a documented API a builder can use? Are the rate limits reasonable? Tools that are otherwise excellent but ship no API drop a tier in categories where downstream tooling matters (e.g. portfolio trackers, indexes).

• Pricing transparency

  weight 15%

  Are the spreads, fees, or paid-tier costs clearly stated? We penalise tools that hide their fee structure behind a sign-up wall or use opaque per-item spreads — even when those tools are fast and clean otherwise.

The five-step process

1. 1

   Load a real CS2 inventory

   We never review a tool from screenshots or marketing copy. Every entry starts with us authenticating the tool against a live Steam inventory (or, for non-portfolio tools, against a real item lookup). If the tool can't be tested with real CS2 data, it doesn't get listed.

2. 2

   Score against the five criteria

   Each criterion above is scored on a 1-5 scale based on what we saw during testing, weighted, and summed. The sum determines whether the tool earns a /best/ slot or shows up only on the broader directory.

3. 3

   Cross-check primary sources

   For price-data tools, we sample 10 random items, look up each on the underlying marketplace's actual listing page, and check whether the tool's quoted number matches within a tolerance the market can produce. Discrepancies are written into the cons list.

4. 4

   Re-test every 90 days

   Every tool entry carries a lastVerified date. We re-test on a rolling 90-day cycle. A tool that goes overdue gets a flag in its sidebar and is excluded from /best/ rankings until it's re-verified.

5. 5

   Publish, then watch for corrections

   Once published, the review is open to corrections via our contact page. If the tool's team disputes a fact (pricing, feature claim, API status), we re-test the disputed point and update if warranted. Disagreements about subjective verdicts stay as the editor's call.

What triggers a re-rank

• A pricing change (e.g. a tool moves from free to freemium).
• A new feature lands that materially affects one of the five criteria.
• A new entrant in the category passes the listing bar.
• A reader-reported correction proves a fact in the review is wrong.
• The 90-day re-verification cycle comes due for that tool.

What we will not do

• Accept payment for inclusion or for a higher rank.
• Fabricate numeric review scores when there is no defensible measurement.
• Remove a documented con because the tool team asked us to.
• List a tool we have never personally used on a real CS2 inventory.
• Auto-rank our own tools at the top of a category.
