  • Versatility
    Randommer offers a wide variety of random data generation tools, making it suitable for diverse applications—from generating fake personal data to creating random numbers and lists.
  • User-Friendly Interface
    The platform features a straightforward and easy-to-navigate interface that allows users to quickly access the tools they need without a steep learning curve.

Possible disadvantages

  • Limited Data Types
    While there are many tools available, the range of data types is somewhat limited if users need very specific or niche random data.
  • Internet Dependence
    Since Randommer is an online service, an active internet connection is required, limiting access in offline scenarios.
  • API Rate Limits
    API access may be subject to rate limits, which could be a drawback for users needing to generate large quantities of data rapidly.
  • Security and Privacy Concerns
    There may be concerns over the security and privacy of data when using online random data generators, especially for applications that require confidentiality.
  • Privacy-first
    Every cryptography tool (hashing, AES, RSA, BIP39 seed phrases, HD wallets, message signing, JWT decode) runs 100% in your browser; nothing is ever uploaded
  • Calculators
    30+ free crypto & finance tools in one place — calculators, converters, and a full cryptography toolkit, plus 8 interactive Bitcoin data studies
  • Cryptography
    Developer-grade web3 tooling — EVM bytecode disassembler, function-selector & ENS namehash, EIP-712 hasher, raw-transaction decoder, Merkle tree, Shamir secret sharing, ECC visualizer
  • Embeddable Widgets
    Every tool is embeddable — drop a calculator or data study into your own site/blog with a copy-paste widget.
  • Multilingual Support
    Works in 10 languages — localized tools and SEO out of the box.

Questions & Answers

As answered by people managing Randommer and CryptoTools.tech.

Who are some of the biggest customers of your product?

CryptoTools.tech's answer:

  • Crypto traders and long-term investors
  • Software and web3 / smart-contract developers
  • Miners estimating profitability
  • Security- and privacy-conscious users
  • Educators, students, and bloggers (who also embed the tools)

What makes your product unique?

CryptoTools.tech's answer:

CryptoTools.tech is a single, fast home for 30+ free crypto & finance tools — calculators, converters, and a full cryptography toolkit — 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 — your keys and data never touch a server. It uniquely covers both meanings of "crypto" — cryptocurrency calculators and cryptography utilities — under one roof, in 10 languages, with every tool embeddable.

Why should a person choose your product over its competitors?

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 — 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 — finance calculators (profit/P&L, DCA backtests, mining, tax) and developer/cryptography utilities — 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.

How would you describe the primary audience of your product?

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.

What's the story behind your product?

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 — fast, free, private, no account — 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.

Which are the primary technologies used for building your product?

CryptoTools.tech's answer:

Built with Astro (static-site generator, ships zero JS by default) and Preact "islands" for interactivity — 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.

  • I'm not brave enough to start a single project even after months of learning
    With your second program, refactor your first to use something like https://randommer.io/ to return the random number. That will be your ONLY API call. Look up JSON Deserialization for GET requests to see how you can get your API call's... Source: about 4 years ago
  • Does anyone deployed .Net5 Web app in DigitalOcean? How is the experience?
    I have multiple websites on a DigitalOcean( ref link - you get 100$, I get $25) droplet (including Randommer - over 5000 daily visits) and I highly recommend it. Source: over 4 years ago
