JSON Crack is a tool for visualizing JSON data in a structured, interactive graphs, making it easier to explore, format, and validate JSON. It offers features like converting JSON to other formats (CSV, YAML), generating JSON Schema, executing queries, and exporting visualizations as images. Designed for both readability and usability.
CryptoTools โ https://cryptotools.tech โ A growing suite of 30+ free, single-purpose crypto & finance tools. Three families: calculators (Bitcoin DCA backtest, profit/P&L + tax, mining, portfolio/tax CSV, staking, leverage, liquidation, position size, impermanent lossโฆ), converters (gweiโETH + gas fee, satoshiโUSD, hashrate), and a privacy-first cryptography toolkit that runs 100% in your browser โ nothing is ever uploaded (SHA-256/keccak hashing, AES, RSA & key generators, BIP39 seed phrases, HD wallet addresses, JWT decoder, plus EVM/ENS/EIP-712 dev tools and more). Plus interactive Bitcoin data studies (DCA backtests, "what if you missed the best days", a monthly-returns heatmap). No sign-up, no tracking, no paywalls; pure static site with sub-second loads; works in 10 languages; every tool is embeddable. For traders, builders, and the privacy-conscious who want a fast answer without a bloated SaaS dashboard.

CryptoTools.tech's answer:
CryptoTools.tech is a single, fast home for 30+ free crypto & finance tools โ calculators, converters, and a full cryptography toolkit โ with no sign-up, no tracking, and no paywalls. What sets it apart: every cryptography tool (hashing, AES, RSA, BIP39 seed phrases, HD wallets, JWT decoding, EVM/ENS dev utilities) runs 100% in your browser โ your keys and data never touch a server. It uniquely covers both meanings of "crypto" โ cryptocurrency calculators and cryptography utilities โ under one roof, in 10 languages, with every tool embeddable.
CryptoTools.tech's answer:
Most crypto tool sites make you sign up, bury the tool under ads and pop-ups, or send your input to a server. CryptoTools is the opposite: privacy-first (client-side cryptography โ nothing is uploaded), instant (static pages, sub-second loads, clean UI), and completely free with no account. You also get both worlds in one place โ finance calculators (profit/P&L, DCA backtests, mining, tax) and developer/cryptography utilities โ across 10 languages, with the formulas shown so you can trust the math. If you value speed, privacy, and not being upsold, it's the cleaner choice.
CryptoTools.tech's answer:
Three overlapping groups: (1) crypto traders & investors who need quick, reliable calculators (profit, DCA, position sizing, liquidation, tax estimates); (2) developers & web3 builders who need cryptography and Ethereum utilities (hashing, AES/RSA, BIP39, JWT, EVM bytecode, ENS namehash, EIP-712); and (3) privacy- and security-conscious users who want tools that run locally and never upload their data. It's global and multilingual, skewing toward technically literate, self-serve users who want an answer without a bloated dashboard.
CryptoTools.tech's answer:
It started from a simple frustration: every "crypto calculator" wanted a sign-up, was slow and ad-choked, or quietly sent your data to a server. So CryptoTools was built as the tool site I wished existed โ fast, free, private, no account โ and grew into a broad cluster spanning both cryptocurrency calculators and cryptography utilities. It's an independent, bootstrapped project with a simple principle: do one thing well per page, and respect the user's time and privacy.
CryptoTools.tech's answer:
Built with Astro (static-site generator, ships zero JS by default) and Preact "islands" for interactivity โ so pages are pure static HTML/CSS/JS with sub-second loads and green Core Web Vitals. Cryptography runs in-browser via audited libraries (@noble/hashes, @noble/curves, @scure/bip39/bip32) and the Web Crypto API. Served by Caddy (automatic HTTPS, HTTP/2+3) on Docker, with a thin optional backend only for live/historical price data. Fully internationalized into 10 languages.

Congratulations on the release, great to see more in this space. At the moment, I'm using https://jsoncrack.com/ which also has a VSCode extension, any chance there's something that like on your roadmap? - Source: Hacker News / over 1 year ago
It seems like a clone of https://jsoncrack.com with a different UI. I couldnโt identify any significant differences aside from the reduced readability in the visualization. - Source: Hacker News / almost 2 years ago
Yes, it requires regular payment, from the SaaS perspective, since the cost is a monthly expense, adopting a subscription model is understandable. This pricing was inspired by https://jsoncrack.com/. May I ask, is there anything on the pricing page that is hard to understand? - Source: Hacker News / almost 2 years ago
Just skimmed through the post but how is it different from a plain json visualiser like https://jsoncrack.com? - Source: Hacker News / almost 2 years ago
