Method
Every number on this site is checked against the vendor's own pricing page, and the date it was checked is printed next to it. Here is the whole process, including where it can fail.
Where the numbers come from
Each price is read off the vendor's own published pricing page, not from a review site, not from a press release, and not from another directory. The link to that page sits in the file next to the figure, so any number here can be checked in one click.
If a price is not published, the file says "not published" rather than estimating. A vendor who hides pricing behind a sales call is telling you something useful, and inventing a figure would hide it.
Why every figure carries a date
Software pricing changes quietly. A page that says "from $19 a month" with no date is worthless six months later, and most comparison pages never say when they last looked.
Every plan row on every file carries its own checked-on date. When a file has not been re-checked recently, that is visible rather than hidden.
What gets tested rather than summarised
Free tiers are the part vendors describe most loosely. Where a file says what a free plan allows, that claim comes from using the free plan, not from the feature grid on the pricing page. The two disagree more often than they should.
The same goes for per-user maths. A headline price of $19 per user per month is a different product at one seat than at twelve, and the multiplication is the figure most buried on a pricing page. It is the first figure on these files.
Corrections
When a figure here is wrong, the file gets corrected and the correction is noted on it. Errors are not quietly edited out. A site whose whole claim is accuracy has to show its mistakes, or the claim is worth nothing.
What this site does not do
It does not rank tools by what they pay. Paid placements, where they exist, are labelled as paid placements on the page they appear on, and they never change the order of a list or the wording of a verdict.
It does not review software it has not used or priced.
It does not publish a figure without a source and a date. That rule is enforced by the publishing system itself: a file missing either field will not build.
