Independence and funding
Editorial ranking published by Ronald Renaud. Funding: Personal project of the publisher. No advertising, no vendor payments. Vendor data comes from the public sources listed on each profile, and the methodology was fixed before data collection. Independence claims are withheld until the publisher's public profile is verifiable (see the editorial policy).
Sources
Only public sources are used: vendor websites, Clutch, G2 and GoodFirms profiles, certification registries and public case studies. Every number on the site has a source and a check date; a field without a source is shown as ○. Material shared privately by a vendor is not used, and rankings published by vendors are not cited as evidence.
Scoring
Weights were fixed before data collection. Scores follow the published scales and interpretation rules on the methodology page. Totals are computed, never typed in.
Wording
Statements about a vendor describe whether public evidence exists, not how good the vendor is. Outcomes from vendor case studies are marked "vendor-published". Every "not the best fit" names an alternative.
Corrections
If a fact is wrong or out of date, the page is corrected and the check date updated. A correction that changes a dimension score is applied only through the same scale, and the total is recomputed.
How a vendor can dispute a fact
Send the page URL, the statement in question and a public source that supports the correction to the address on the contact page. A public source is a page anyone can open without a login or form. Private documents cannot be used, because readers could not check them.
