Core features include a real-time webhook inspector that displays incoming request headers, parameters, and body without page refreshes, and a DNS Sandbox that checks MX, SPF, and DMARC records with remediation suggestions. Other tools cover JWT decoding, JSON/SQL/YAML formatting, regex testing, SSL inspection, Base64 conversion, and more — most running client-side for speed and privacy. The stack uses Next.js, FastAPI/Python, Supabase, Stripe, and Google Cloud Run. A free tier requires no signup for browser-only tools; a Pro tier removes ads and unlocks unlimited backend workflows. The project also includes 100+ technical guides on topics like webhook reliability, API design, and distributed systems. ## Full article daily.dev links to this article rather than hosting it.
