FAQ
Common questions
Are these tools actually free?
Yes — both are MIT-licensed and free to use, fork, or self-host. No paid tier, no account required.
Can I self-host or modify them?
Both repos are open source under MIT. Clone them, change what you need, run them wherever you want.
Why is the Domain Finder embedded but not Lead Finder?
Domain Finder already runs entirely in a browser. Lead Finder drives a real Chromium instance and writes files to disk — that only makes sense running on your own machine, so we didn't fake a demo for it.
Does the Domain Finder demo use a paid API?
No. It checks DNS first, then falls back to a free RDAP registry lookup — nothing paid, nothing mocked.
Do you take on client work?
Yes — KPThink builds production-grade software for clients. These tools are a sample of that standard, built for ourselves and open-sourced. Get in touch.
