Engineered for speed. Built for absolute privacy.
Netfox (netfox.space) is an independent, developer-first hub of client-side web utilities created to eliminate the dangerous habit of pasting sensitive credentials, JWTs, and API payloads into unverified third-party online tools.
100% Client-Side WebCrypto
Every cryptographic hashing operation (HMAC-SHA256/512), JWT claim decoder, and regular expression evaluation runs strictly inside your local browser memory using the W3C Web Cryptography API (`crypto.subtle`). Your secrets never touch an external backend.
Zero-Latency Static Edge
Netfox is statically generated (SSG) with Astro. Once the lightweight bundle loads, all tools function seamlessly without internet connectivity or server round-trips.
Our Engineering Team & Standards
Netfox is maintained by full-stack infrastructure engineers, security auditors, and open-web advocates. We adhere strictly to RFC specifications, including RFC 7519 (JWT), RFC 2104 (HMAC), RFC 9110 (HTTP Semantics), and POSIX IEEE Std 1003.1.
