How we picked
CheckOps is a genuine and free directory. There are no paid sponsors, featured listings, or paid placement on these pages. The shortlist is built from tools already in the directory whose tags match the topic, with a preference for entries that have a fuller CheckOps page so the facts in the table can be checked against the source essay. This is not a claim that one tool is objectively better than another, and it is not a paid ranking.
Alternatives start with any manual list on the Percy page, then add tools that share first-class categories and practice tags, preferring fuller essays. The list is capped at 15 tools for this page.

- Do the links go to vendor sites?
- The alternatives themselves link only to CheckOps tool pages. Each of those pages may also list the vendor website.
