Pricing Research Methodology

Last updated: March 2026

StackScored is a primary research source for SaaS pricing data. We don't aggregate data from other review sites or rely on vendor-submitted information. Every price on this site is collected directly from live vendor pricing pages by our automated systems, validated against strict schemas, and tracked in version control. This page explains exactly how.

1. How We Collect Prices

Our pricing data comes directly from vendor websites — not from press releases, not from third-party databases, and not from vendor self-reporting. Here is the exact process:

  1. Automated headless browser scraping. A headless Chromium instance running on Google Cloud Run (us-central1) visits each vendor's public pricing page. This runs on a US-based IP address to ensure we see US pricing by default.
  2. Structured extraction. The scraper extracts plan names, monthly prices, annual prices, renewal prices, free plan availability, trial durations, plan limits, and key features into a structured format.
  3. Zod schema validation. Every extracted data point is validated against a strict Zod schema before it enters our dataset. If a scrape returns data that doesn't match the expected structure (e.g., a price field containing text instead of a number), the validation fails and the stale data is retained rather than publishing incorrect data.
  4. Git-tracked changes. Every pricing update is committed to version control. This creates a complete, auditable history of every price change for every product. You can trace exactly when a vendor raised prices, removed a free plan, or changed plan limits.

2. Verification Frequency

Every product's pricing data is re-verified against live vendor pages every 24 hours. This is not a marketing claim — it is an operational requirement enforced by our automated pipeline.

  • Every page on StackScored displays a lastVerified timestamp showing exactly when that data was last confirmed against the vendor's live pricing page.
  • Products that haven't been verified within 48 hours are automatically flagged as "stale" and marked visually on the site, so readers always know the freshness of the data they're viewing.
  • Our verification status has three levels: Verified (confirmed within 24h), Unverified (new data pending confirmation), and Stale (older than 48h).

3. Currency Accuracy

SaaS vendors frequently show different prices based on the visitor's geographic location. To ensure consistency and comparability across all products:

  • All scraping runs from US-based IP addresses (Google Cloud Run, us-central1 region) to ensure we capture USD pricing.
  • When a vendor's pricing page includes a currency selector, our scraper confirms that USD is the active currency before extracting prices.
  • All prices on StackScored are displayed in USD ($). When a vendor does not offer USD pricing, we note this explicitly on the product page.

4. What We Track for Every Product

For each product, our dataset captures a comprehensive set of pricing and feature data points. This is not a selective summary — it is the complete data model:

Monthly Price The month-to-month price with no annual commitment.
Annual Price The per-month cost when billed annually, showing the actual discount.
Renewal Price The price after introductory offers expire. Many vendors hide this.
Free Plans Whether a genuinely free tier exists, and what its limits are.
Free Trial Duration Exact trial length in days, and whether a credit card is required.
Plan Limits Users, storage, contacts, emails, sites — the real constraints of each plan.
Key Features Category-specific features (e.g., uptime guarantee for hosting, deliverability rate for email).
Pricing Model Per-user, flat, tiered, per-subscriber, per-email, usage-based, or freemium.

5. StackScore Calculation

Every product receives a StackScore from 0 to 100. This score is computed algorithmically from four weighted components — no subjective "gut feeling" adjustments. The formula is applied identically to every product in a category.

30%
Price Competitiveness

Compares the product's lowest paid plan price against all competitors in the same category. Products with free plans receive the maximum score. The calculation uses relative positioning: score = (1 - yourPrice / highestPrice) * 30.

25%
Feature Coverage

Measures what percentage of category-relevant features the product offers. Boolean features (has/doesn't have) count fully. Features with partial support (e.g., available only on higher tiers) count at 50%.

25%
Editorial Assessment

Our editorial score (0-10 scale, normalized to 25 points) captures qualitative factors that automated data cannot: documentation quality, UI/UX, onboarding experience, support responsiveness, and ecosystem maturity. Products without an editorial review receive a neutral midpoint score.

20%
Bonus Factors

Up to 20 additional points for consumer-friendly practices:

  • Free plan available: +7 points
  • Free trial offered: +5 points
  • Stable renewal pricing (no price hikes after intro period): +5 points
  • Verified status (pricing confirmed within 24h): +3 points

6. Editorial Independence

Our revenue comes from affiliate commissions: when you click a link on our site and make a purchase, the vendor pays us a referral fee. You pay the same price you would pay going directly. That is the full extent of our financial relationship with vendors.

  • No paid placements. Vendors cannot pay to appear higher in our rankings. Position is determined solely by the StackScore algorithm described above.
  • No vendor influence on scores. Commission rates are not a factor in the StackScore calculation. We frequently rank products with lower commissions above those with higher commissions when the data supports it.
  • No pre-publication review by vendors. Vendors do not see or approve our content before it is published. Our analysis is based on publicly available pricing pages that any person can verify.
  • Full disclosure. Every page containing affiliate links is marked with an "(Ad)" disclosure above the fold, before any product content. See our full affiliate disclosure for details.

7. Data Corrections & Error Handling

When we discover an error in our data — whether through our automated monitoring, vendor notification, or reader feedback — our correction process is immediate and transparent:

  1. Immediate fix. Incorrect data is corrected as soon as it is identified. There is no "next update cycle" — stale or wrong data is treated as a bug with highest priority.
  2. Git history as audit trail. Because every data change is committed to version control, the complete history of corrections is permanently available. Anyone can review what changed, when, and why.
  3. Automated anomaly detection. Our monitoring system flags unexpected changes — such as a price dropping by more than 50% or a plan disappearing — for human review before publishing. This prevents scraper errors from reaching the site.

8. Current Coverage

StackScored currently provides primary pricing research for 5 software categories, covering 26 products across 94 individual pricing plans:

For each product, we generate multiple analysis pages: a detailed pricing breakdown, head-to-head comparisons against every competitor, alternatives pages, persona-based recommendations (best for freelancers, small teams, enterprises), cheapest options, and free plan guides. This results in over 130 research pages, all updated daily.
