Toolsaur

Toolsaur is a serverless utility hub engineered for developers, system administrators, and content editors. Unlike typical online tools that process inputs on remote servers, Toolsaur runs entirely on a zero-trust, client-side architecture. Every operation executes locally within your isolated browser sandbox. Core toolsets available instantly: • Data utilities: Format, parse, and validate complex JSON and YAML structures. • Network calculators: Compute accurate VLSM subnets, CIDR blocks, and netmasks. • Operational tools: Generate version 4 UUID strings and convert Unix epoch timestamps. • Security & text: Hash data with SHA-256, encode to Base64, and sanitize raw strings. All processing runs locally in your browser. Your data is never sent to our servers. Inspect the network tab at any time to verify compliance. No sign-ups, no tracking cookies, and zero friction.
