Candid Tools packs 34 free, privacy‑friendly dev utilities into a single website

A new website called Candid Tools has quietly launched as an all‑in‑one toolbox for developers who live in the browser. Instead of juggling dozens of small utilities, users get 34 focused tools in a single place—covering everyday tasks such as JSON formatting, URL and Base64 encoding/decoding, regex testing, JWT inspection, colour conversion, and responsive layout previews.

All of the utilities run entirely client‑side, meaning everything executes in the user’s browser without sending data to a server. That privacy‑by‑design approach makes it safer to paste sensitive logs, API tokens, or payloads that developers normally hesitate to upload to random sites. No sign‑up is required, and the interface is intentionally minimal so tools load almost instantly.

While many of these utilities exist as separate websites or native apps, Candid Tools bundles them into a single, easily bookmarkable destination. For engineers who switch devices frequently or work in locked‑down corporate environments, having a zero‑install, browser‑based toolkit can be a practical productivity boost—and it’s likely to appeal to Japanese developers looking for lightweight helpers they can use from any machine.
