How this table is built

Every cell comes from the plan's entry in our data, which quotes the vendor's pricing page linked in the Last verified row. Models, reset windows, what happens at the limit, seats and coding-agent or API access are the vendor's own sentences, picked out of the plan's published limits; nothing is estimated. Not published means the cited page doesn't state it; — means it doesn't apply to that kind of tool. Highlight differences marks the rows where the plans don't match.

Columns stay in the order you pick them. Affiliate deals never change which plans are shown, their order or their cells; only the Try link can be an affiliate link, and it says so.
