Why are they free?
Stackboo is a weekly launch board for SaaS and AI products, ranked by votes and not by budgets. The people who use these tools are the people who launch there, so we build what a founder needs on launch day. If you find them useful, you can list your own product for free.
The tools that read a page fetch only the address you give them, keep nothing, and have a small limit per minute. The others run entirely in your browser.
