Possible disadvantages

  • Learning Curve
    Obsidian can be complex and overwhelming for beginners due to its extensive features and customizable nature.
  • Sync Limitations
    While local-first is great for privacy, it requires additional steps or third-party solutions for syncing across devices.
  • No True Real-time Collaboration
    Obsidian lacks native real-time collaboration features, making it less suitable for collaborative work compared to cloud-based solutions.
  • Limited Mobile Features
    The mobile version of Obsidian, while functional, is not as robust as the desktop application, potentially hindering productivity on the go.
  • Dependence on Plugins
    Many advanced features require the use of third-party plugins, which could lead to compatibility issues and reliance on community support.
  • Performance on Large Vaults
    Performance might degrade with a very large number of notes or complex graphs, impacting usability.
  • 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

Questions & Answers

As answered by people managing Obsidian 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.
