I'm Rahul, a full-stack software engineer with more than ten years building web platforms, internal developer tools, and cloud infrastructure — most of it in fintech and SaaS, where the data you handle every day is exactly the data you are not allowed to paste into a random website. That constraint is why AllDevToolsHub exists. I kept hitting the same wall: mid-incident, I would need to decode a JWT, diff two JSON payloads, or check a certificate, and every convenient online tool wanted me to upload the thing I was debugging to a server I did not control. So I started building browser-only versions, first for myself in early 2024, then as a public site. The rule has stayed the same: if a task can run on the client with the Web Crypto API, WebAssembly, or plain JavaScript, it runs there, and the tool page says so. The handful of tools that genuinely need a server (DNS and WHOIS lookups, the AI features) carry a disclosure before you use them. In 2026 I stopped adding tools for a while and ran an editorial review instead. The catalogue had grown past what one person could keep accurate, so I narrowed the indexed set to around 100 tools I actively maintain plus a small research journal, and marked the long tail noindex rather than deleting it. The benchmark articles, AES interoperability across languages, JSON parser throughput, JWT library failure modes, are things I actually tested, with the methodology and raw numbers in each post. What I do not claim: I am not a cryptographer, I hold no security certifications, and I am not a designer. Where a tool touches something I am not an expert in, it leans on the relevant RFC or spec and links to it, and the known-limitations section on each page is honest about what the tool cannot do.
