As answered by people managing DevBox and Tech4dream Tools.
Tech4dream Tools's answer:
Utilo runs entirely in the browser with no backend, so your data never leaves the device. It combines 30+ developer tools (JSON, JWT, Base64, regex, hash, UUID, timestamps) with 48 format converters, a unit converter, barcode/QR tools, and reference pages for HTTP status codes, cron presets, MIME types, and network ports. It is available in 10 languages, needs no account, and is free forever.
Tech4dream Tools's answer:
Choose Utilo when you want a private, no-install alternative to toolkits like IT-Tools, CyberChef, DevToys, and Transform.tools. Everything runs client-side in Chrome, Firefox, Safari, or Edge: nothing is uploaded, there is no signup, and there is no paid plan. You get everyday dev utilities plus 48 converters (JSON to TypeScript, cURL to Python, cron to English, and more) in one free site.
Tech4dream Tools's answer:
Software developers, QA engineers, and people who work with data and need quick local utilities. Typical use is formatting JSON, decoding a JWT, encoding Base64, converting units, or translating a cron expression or cURL command without installing an app or creating an account.
Tech4dream Tools's answer:
Utilo is a small personal project: a free collection of developer utilities that stay on the user's device. It is published as a static site so common formatters, converters, and reference lookups do not require an account or a backend. The source repository is private for now.

Tech4dream Tools's answer:
Next.js, deployed as a static site on Vercel. The tools themselves run client-side in the browser. There is no public API and no mobile app. Support is by email at beself29@gmail.com or the contact page on the site.
