These tools are free to use outright — not free trials, and not paid products with a limited free tier. Tools that merely include a free plan alongside paid ones are listed separately, because the difference matters when you are choosing something to rely on.

What to check before you choose
Free tools still have limits, and they are rarely the same limits. Some cap how much you can generate per day, some restrict commercial use, and some are free because the product is early and still changing. Before you build a workflow on a free tool, it is worth checking how the maker funds it — an open-source project and a venture-funded free beta tend to age very differently. Where a tool also publishes paid plans, you will find that noted on its own page.
