"Finally replaced 12 different browser bookmarks with a single dashboard. The JWT decoder alone saves me 20 minutes a day debugging auth issues."
"The privacy guarantee is what sold me. I paste internal API responses and database exports here daily — knowing it never touches a server is essential."
"The clipboard detection is like magic. I copy a CIDR range and it immediately suggests the subnet calculator. My team adopted it org-wide within a week."
"As a technical SEO consultant, the UTM builder and OG tag tester save me hours of back-and-forth with developers every week. Worth every cent."
"The AI agent hooks are next-level. My Claude Code setup calls bitbox to format SQL and validate regex without me switching focus. Total flow state."
"Replaced our internal Notion 'utilities' page. The CSV parser and diff tool are particularly solid. The interface is gorgeous — my whole team uses it daily."
