A Note on This List
We deliberately avoided including anything with a "free trial" that actually requires a credit card, or tools where the free tier is too limited to be genuinely useful. Every tool above has a real, usable free tier as of this writing — but terms change, so always double-check current pricing on the provider's own site before assuming.
