CipherKit is a privacy-first suite of 80+ developer tools designed for enterprise engineers. It includes JSON formatters, JWT decoders, AES encryption, Hash generators, and text utilities that run entirely locally in your browser. Built with Vanilla JS and Web Workers, it features no backend, zero data tracking, and no server uploads—making it completely safe for pasting sensitive API payloads and proprietary code.

CipherKit.app's answer:
Most legacy developer tools send your sensitive JSON payloads, JWTs, and encryption keys to a backend server, often logging data or running heavy ad-tracking scripts.
CipherKit is built differently. It is an enterprise-safe utility suite engineered for absolute privacy:
CipherKit.app's answer:
Developers should choose CipherKit over legacy competitors because it finally solves the "security versus convenience" dilemma.
CipherKit.app's answer:
The primary audience is software engineers, DevOps professionals, and security analysts. It is specifically designed for developers working in strict enterprise environments—like fintech, healthcare, and large corporate networks—where corporate firewalls block legacy online tools, and Infosec policies strictly prohibit pasting proprietary API payloads into external websites.
CipherKit.app's answer:
As a Software Engineer working in fintech, I constantly needed to debug API payloads, format JSON, and decode JWTs. However, I quickly realized that pasting sensitive company data into random, ad-heavy online formatters was a massive security violation. I searched for a clean, privacy-first alternative but couldn't find one that didn't track data or send it to a backend server. So, I decided to build CipherKit myself—a tool that the strictest Infosec teams would actually approve for their developers to use.
CipherKit.app's answer:
To guarantee absolute data privacy and offline capability, CipherKit is built entirely without a backend. The primary technologies include:
CipherKit.app's answer:
CipherKit is a free, open-source tool built for the community, rather than a paid B2B enterprise product. Its "customers" are individual software engineers, security analysts, and IT professionals working inside strict corporate networks who rely on it daily as their safe, locally-hosted utility suite.
I've been using CipherKit.app as my daily driver for developer utilities, and it has fundamentally streamlined my workflow. The standout feature is its uncompromising approach to privacy. Knowing that the platform operates completely client-side gives me the confidence to paste sensitive JSONs, JWT tokens, and proprietary code snippets without ever worrying about tracking or server-side processing. Having a massive suite of 85 different tools instantly accessible in one centralized hub means I no longer have to bounce between random, ad-riddled websites to format data, generate hashes, or decode strings. Because there is zero network latency involved in the processing, everything happens instantly as you type. The interface is exceptionally clean, intuitive, and clearly designed with a developer's fast-paced workflow in mind.

Even better is the licensing model where you can keep using the version as-is after the subscription ends. You just don't get any new features. It's even possible to do on iOS, as Working Copy [0] is doing it. (You also get all the bug fixes and stuff, only new features are behind a flag that requires you to purchase another year of updates. I would also argue that Working Copy specifically is too cheap, but I... - Source: Hacker News / almost 3 years ago

So I have a laptop and a iPhone. On laptop I have the Obsidian.md desktop app, on iPhone I have the app and Working Copy app too. This is all for syncing my notes. Source: over 3 years ago
> It uses the same format of storage as Obsidian... Can Obsidian and Jot co-mingle in the same vault? I use Obsidian and am very happy with the git plugin[0] and Working Copy(iOS)[1] for keeping things automatically synced between my phone and desktop(s). Often I find myself dumping notes into random places from the terminal; feeding markdown via pipes.

Why this matters for security Unlike old-school math-based pseudo-random generators (Math.random()), crypto.randomUUID() uses the underlying operating system's hardware-backed entropy. It's fast, secure, and doesn't bloat your production bundle. Need to generate UUIDs on the fly? If you just need a batch of secure keys for configuration files, database testing, or environment variables, stop pasting your... - Source: dev.to / 3 months ago
