THE STORY
I built NameSnag for founders and builders who are stuck naming a new product. It takes a plain-English product idea, generates brandable domain options, checks live availability across .com, .net, .ai, .io, .app, and .dev, and lets users watch taken domains until they appear available.
The first version started as a simple “generate available names” tool, but the sharper recurring hook was domain monitoring: if the name you really want is taken, NameSnag keeps checking it and emails you when it may be available. I shipped the production app on namesnag.io with Google auth, scheduled watch checks, Resend email alerts, and Polar billing for a $19/mo Pro plan.
LESSONS LEARNED
The generator was the easy part. The product became more interesting when it shifted from “give me names right now” to “watch the name I actually want.” Availability data is also messier than it looks: RDAP is useful, but registrar checkout is still the final source of truth.
