The method, in full

This page is the contract behind every number on this site. If a comparison here ever breaks one of these rules, write to us and we will correct it — dated, on the page.

What we record

A tracker reads the public pricing page of each covered vendor once a day (05:40 UTC) and stores: the HTTP status, a content fingerprint, the prices found on the page, and — whenever anything changed — a full snapshot of the page. Observations are append-only: new facts are added, old facts are never edited or deleted.

Coverage now: 157 vendors across 13 software categories (email & marketing, SEO, VPN, security, hosting, site builders, project tools, AI, CRM, accounting, helpdesk, cloud storage, e-commerce), the first 25 since 25 August 2026, the rest added 26 August 2026. How often: most tools’ pages are read automatically every day at 05:40 UTC. A minority block robots — those get a by-hand check via a real browser about once a week. The few that block even that are listed as “waiting for their first check” and are never shown with data we don’t have.

Rules we hold ourselves to

• No guessing. A page we could not read on a given day is recorded as unread. A price we could not parse is shown as “last verified” with its date — never silently shown as current.
• Source on every row. Each fact links the vendor page it came from and the date we read it.
• History is never rewritten. Corrections are appended and dated. The wrong version stays visible as struck text.
• Facts only from the vendor. Prices, plans and limits come from the vendor’s own pages. We do not copy marketing prose, and we do not republish third-party review scores.
• Staleness is shown, not hidden. Every page displays when its data was last verified. Data older than 90 days is flagged on the page.

Disclosure

Some outbound links earn us a commission if you buy. Those links are marked — with the label required in your market — and they change nothing about the data: which vendors we track, what the record says, or how comparisons read. No vendor can pay to be included, excluded, ranked, or described differently. If a vendor has no commission program, they are covered exactly the same way.

The verified-price badge a vendor may embed asserts one thing only: that we read that vendor’s public pricing page on the date shown and published what it displayed. It is not an endorsement, not a ranking, not a statement about any figure that was not on that page, and never a condition of coverage — the badge page says so in the same words.
