How we score and update every tool.

The DuelStack Score (out of 10)

Every tool we track gets a single composite score from 1.0 to 10.0. It's the weighted average of five sub-scores, each judged 1–10:

• Value for money (weight: 25%) — does the price match the capability?
• Core features (weight: 25%) — depth and reliability of the headline use cases.
• Ease of use (weight: 20%) — onboarding friction, learning curve, UI clarity.
• Ecosystem & integrations (weight: 15%) — APIs, native connectors, third-party support.
• Support & trust (weight: 15%) — docs quality, response times, longevity, security posture.

We round to one decimal. A 7.0 is a clear pass. An 8.5+ is something we'd hand a friend. Below 6.0 we don't usually publish a verdict unless the tool is widely used enough that omitting it would be misleading.

Pricing data

Every weekday at 7 AM Eastern, an automated job reads the public pricing page for every tool we track. If anything changes — a new tier, a renamed plan, a price up or down — the database updates and we get an alert.

We list prices in USD on a monthly basis. Annual pricing is shown as the equivalent per-month rate. Enterprise tiers without a public price are flagged as "Contact sales" and excluded from the starting-price field.

The last pricing pull is timestamped on every comparison and tool page. If you see a date older than 48 hours on a weekday, the scraper failed — please tell us.

Features and capabilities

Feature flags are set by hand. We read the vendor's docs, sign up for the free tier when possible, and test the headline workflows. We don't take feature claims at face value — if a vendor says "AI-powered" and the AI's just regex, we'll say so.

When we can't verify something firsthand, we note it. Anything marked with a dash (—) on a comparison table means we couldn't confirm one way or the other.

Pros and cons

Pros and cons come from three sources, weighted in this order:

1. Our own hands-on testing
2. Aggregated reviews from G2, Capterra, TrustRadius, and Reddit threads
3. Vendor-published case studies (used cautiously)

We don't copy bullet points from other comparison sites. If two sites agree on a con, that's independent confirmation, not a license to plagiarize.

The verdict

Every comparison ends with a clear pick — not a hedge. If two tools are genuinely tied, we say so and split the recommendation by use case (e.g., "Tool A if you're solo, Tool B if you're a team of 10+").

We don't avoid hard calls. We'd rather be wrong and correctable than vague and useless.

When we're wrong

We make mistakes. When a vendor or reader tells us we got something wrong, we fix it, timestamp the correction, and (if it changes the verdict) note it on the comparison itself.
