About free tools

Are these tools really free?

They are the 4,074 entries marked as free in our snapshot. Most offer a free tier or free basic features rather than unlimited free use; check each vendor site for current limits.

Why are some obviously free tools missing here?

Because their pricing model is not recorded in the snapshot. Only 68% of entries carry a pricing model, and unlabelled ones are excluded on purpose — better to omit than to guess.

Is a free tool enough?

Usually enough for light personal use. For bulk output, evaluate paid plans — usage-based pricing is often cheaper than a subscription.

How this is counted: "Free" means price_model is Free in our snapshot; it does not mean unlimited free use forever. Entries without a recorded pricing model are not listed.
