How we choose and check these tools

  • Prices and free-plan limits come from each vendor's own pricing page, and every tool shows the date we checked it. When a vendor's page didn't show a price, we say so instead of guessing.
  • We list tools a one-person business can actually use: a plan for a single user, a sensible starting price, and a track record.
  • No paid placements. Vendors can't pay to be listed or to rank higher. If we ever use an affiliate link, it's labelled on the page.
  • We haven't run long-term tests of every tool, so the pros and cons describe what the official documentation and pricing show, not hands-on reviews.
