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, we do not verify pricing, and the criteria are structural (what a product publishes) rather than qualitative (how well it works). Where a product does not state something, the table says so instead of guessing.
