Frequently asked
Does the kit only work on Cloudflare Workers + D1?
The kit is written for Cloudflare Workers + D1, so the prompts, schema and patterns assume it. You can port an idea to another stack, but the least friction is building it on the stack its kit targets.
Do I need to know Cloudflare Workers + D1 already?
It helps, and it is the point of picking by stack: on a stack you know, you can judge the agent's output and unblock it faster. The kit still carries the standard patterns for you.
How are these ideas scored?
Against the same eight-signal UIQ rubric as the whole catalog, with codeability measuring how cleanly an agent can build it. Anything under 55 never publishes.
Can I see one in full first?
Yes. The Idea of the Week is unlocked completely and free, with no account needed at all.
What will it cost to run on Cloudflare Workers + D1?
Almost nothing until there is real usage: every stack here has a generous free tier. The run-cost estimator gives a rough monthly figure by stack and scale, free and without an account.
How long does one of these take?
It depends on the idea's difficulty and the hours you can give a week. Every card shows difficulty out of five, and the MVP time estimator turns that into an honest number of weeks.
