A BlockSurvey Alternative for Encrypted Forms
BlockSurvey helped popularize privacy-first surveys. Cyphorm targets the same outcome—provider cannot read answers—with conventional Web Crypto and without blockchain positioning.
The technology difference
BlockSurvey built its privacy story around blockchain-based infrastructure and decentralized identity (Stacks/Bitcoin). That appeals to users already in the Web3 ecosystem, but it can be a barrier for mainstream enterprise buyers who want the security guarantee without the vocabulary or wallet requirements.
Cyphorm achieves the same zero-knowledge outcome using standard browser APIs: RSA-OAEP for asymmetric encryption and AES-GCM for payload encryption, all via the Web Crypto API. No blockchain, no tokens, no wallet onboarding. The private key lives in your browser's storage and is backed up via QR codes or password manager export.
| Feature | Cyphorm | BlockSurvey (typical) |
|---|---|---|
| Zero-knowledge ethos | Yes (RSA in browser) | Yes (different stack) |
| Blockchain / Web3 in product story | No | Often central to brand |
| Paid from | $12/mo Pro | Often higher (e.g. ~$39/mo tier) |
| Free tier encryption | Yes | Verify on their site |
| Wallet or token required | No | May require Web3 wallet |
Where Cyphorm wins
Mainstream buyers who want the security story without Web3 vocabulary; lower Pro price point for many teams; ciphertext proof on our homepage. Enterprise procurement teams are more likely to approve a tool that uses standard browser cryptography than one tied to a blockchain ecosystem.
Where BlockSurvey wins
Community tied to their ecosystem; feature depth for users already bought into their stack. If your organization is already using Stacks identity or values the decentralized architecture story, BlockSurvey's approach aligns naturally.
