BID Name Checker — Domain, GitHub, Trademark for Founders

One-click name availability for founders. Check .com / .io / .co / .ai / .app domains, GitHub org, and trademark status in seconds.

Naming your next startup, side project, or SaaS? Stop opening twelve tabs. BID Name Checker turns the most tedious part of starting something new into a single click. Type a candidate name, and in under a second you see: ✓ Domain availability across .com, .io, .co, .ai, and .app ✓ Whether the GitHub org or username is free ✓ A direct USPTO trademark search link ✓ Whether someone has already built a similar idea (matched against the Business Ideas Database) No accounts. No subscriptions. No keys. Everything runs locally in your browser against free public APIs. WHO IT'S FOR - Indie hackers naming their next product - Solo founders brainstorming domain options - Builders who want to sanity-check a name before they fall in love with it - Anyone tired of the open-twelve-tabs naming ritual HOW IT WORKS 1. Click the BID icon in your toolbar 2. Type or paste a product name (just the name — no .com needed) 3. See domain, GitHub, and trademark status, plus any overlapping ideas already in the BID database WHAT IT DOESN'T DO - No tracking, no analytics, no cookies - No background scripts running on every page - No data sent to any server we run, except an anonymous query to businessideasdb.com to check for idea matches - No paid tier, no upsell pop-ups ABOUT BID The Business Ideas Database (businessideasdb.com) is a curated library of validated business ideas sourced from real Reddit pain points, App Store gaps, and keyword demand data. Updated weekly. This extension is free and works standalone — but if you want validated ideas with real proof, that's where to look. PRIVACY The extension calls three public APIs: - dns.google for domain availability via DNS-over-HTTPS - api.github.com for GitHub username availability - businessideasdb.com/api/ideas/match for idea overlap (read-only, no auth) USPTO is opened as a deep link only, no API call. No personal data is collected, stored, or transmitted. Full privacy policy at businessideasdb.com/privacy-policy.
