About

ValidateThis (validatethis.org) is a decision-first trust layer: quick checks for websites, email, phone numbers, companies, payments, and risky text — so you can approve, pause, or escalate before you click, reply, or pay. Most tools run in the browser with no signup for basic use.

Alongside trust tools, we host free format and web validators (JSON, XML, YAML, CSV, HTML, robots.txt, Schema.org, and more) and practical guides for common parse errors — useful for developers, CI-style checks, and AI-assisted editing workflows.

Deeper infrastructure security scans and technical SEO live on partner hubs we link to deliberately, so this site stays focused on fast trust and validation — not duplicate stacks.

Where to start

• Trust tools directory — browse by category (websites, email, company, payments, text).
• Web & format validators — JSON, XML, SOAP, YAML, CSV, feeds, CI configs, and related hubs.
• JSON tools & error guides — long-tail help for invalid JSON and API payloads.

Example format validators
