How the listings are written

Every entry here was written for this directory rather than copied from the vendor. Each one says what the tool does, who it is a good fit for, and where it stops being one, because a listing that only repeats marketing copy is no use to anyone deciding between three options.

Pricing describes the software itself: free means no payment to use it, a free tier means a plan you can stay on indefinitely with paid tiers above, and paid means there is no free plan. That is separate from whether the listing here was paid for.
