Instant Username Search nails one thing: real-time username availability that updates as you type, no signup, no friction. Built solo by a software engineer in 2019, debuted #3 Product of the Day on Product Hunt. NameSniper is the same loop without ads, and adds domains, trademark screening, monitoring, and AI generation.
Instant Username Search is a popular solo-engineer project (founded 2019, Product Hunt #3 of the day) that does one thing well: real-time, type-as-you-go username checking with no signup. An AI Username Genie beta appeared in early 2026 but is no longer surfaced on the site; per-platform sub-pages for Instagram and TikTok remain. NameSniper is a different category: dedicated checks across the major social platforms with confidence scoring, plus domains, trademark, AI generation, brand scoring, monitoring, and an MCP server - no ads.

Why our platform count is smaller: a platform stays on the list only if we can produce a verdict we would bet on. Some networks cannot be read by a plain HTTP request at all, so we confirm those through verified data instead of guessing, and every result carries a confidence score. How we check
