How the data is collected

No scraped price is published without the page it came from and the date it was read.

Rules

• Every price is read from the vendor's own pricing page. Each tool page links to that exact URL.
• No price is inferred. When a vendor only publishes the annual rate, the monthly column says "not published" instead of showing an estimate.
• Currencies other than USD are not converted only where the vendor states them; a price in another currency is marked as such.
• Enterprise tiers with "contact sales" are recorded as such; no assumed number is inserted.
• Costs are calculated, not copied: annual cost = rate x 12 x seats for per-seat plans, rate x 12 for flat plans.

Update cycle

Pricing pages are re-read on a weekly schedule. Each re-read is written to a change log, so a price change has a timestamp instead of appearing silently. Pages show the date of the last successful read. Currently indexed: 25 tools.

What this site does not do

No feature scoring, no review scores, no affiliate ranking. The order of the tables is price, not commission. If a listed price is wrong, the source link is on the same page and the entry is corrected after re-reading the vendor page.
