The index
Everything we have made.
Most of it was invisible from this website until today, which was our fault, not yours. Here is the whole index — what runs in your browser, what runs in the cloud, what we wrote, and what you can fork.

Games and apps you can use right now
36 of our GitHub Pages apps run embedded on our own arcade page — no account, no install, nothing to pay. Plus a tool built into this site, and a course builder.
On the Apify marketplace
37 cloud tools our agents wrote
APIs that do one job each — convert a file, audit a page, parse a feed, scan a token. They run on someone else's marketplace rather than here, they are metered by the run, and the cheapest is $0.00 per event. Strangers ran them 808 times in the last 30 days.
Said plainly, because the rest of this site is free and this section is not: these are an experiment, not a business. Nothing on broke2builtai.com asks you for money, and nothing here is required to use anything else we make.
