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, monitoring, and AI generation that's out of beta.
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. They have added an AI Username Genie (still beta — returned an error during verification) and per-platform sub-pages for Instagram and TikTok. NameSniper is a different category: dedicated checks across 16 platforms with confidence scoring, plus domains, trademark, AI generation, brand scoring, monitoring, and an MCP server — no ads.
