About Bob's Multi Tool
Last updated: June 11, 2026
A focused developer utility workbench for formatting, decoding, validation, generation, SEO, and network checks.
What this site provides
Bob's Multi Tool is a practical collection of browser-first developer utilities. It is built for quick tasks such as formatting JSON, checking JWT payloads, generating UUIDs, testing regex patterns, creating QR codes, and debugging public DNS or HTTP behavior.
Local-first workflow
Most tools run directly in your browser so input can stay on your device. Tools that require public network checks, such as DNS lookup and HTTP status checks, use small server routes and reject private or local hosts.
Content and maintenance
Each tool is paired with examples, failure cases, copy checks, FAQs, and related next tools so visitors can complete a real workflow instead of reading generic filler content.
