## How to read this

Every fact on this page is copied from the product's own site or repository and dated. We do not test these tools hands-on, and the criteria are structural (what a product publishes) rather than qualitative (how well it works). Pricing is read off each product's own pricing page and carries the date it was read, so check the current page before budgeting. Where a product does not state something, the table says so instead of guessing.
