How to read the comparison table. 'Best for' is the honest one-line answer to who should buy this ai agents AI tools tool — not a feature list. If that line does not describe you, skip the tool regardless of price. Free plan column reflects what you can ship, not trial length. A 7-day trial is not a free plan and we mark it accordingly.
