Comparison

BytesBit vs OneTimeSecret

Both tools let you share secrets with self-destructing links. But they differ in encryption model, pricing, and privacy guarantees. Here's an honest, feature-by-feature breakdown.

TL;DR

Choose BytesBit if you need:

  • True zero-knowledge encryption (key never leaves your browser)
  • No sign-up required, generous free tier
  • Bot protection for Slack/Teams/Discord links
  • PBKDF2 passphrase protection (600K iterations)

Choose OneTimeSecret if you need:

  • REST API for programmatic secret sharing
  • Self-hosted deployment on your own servers
  • Custom branding / white-label solution
  • Open-source codebase you can audit

Feature-by-Feature Comparison

FeatureBytesBitOneTimeSecretNotes
Client-Side Encryption✅✅Both encrypt before data reaches the server
AES-256-GCM✅—OTS uses server-side encryption, not browser-native AES-GCM
Zero-Knowledge Architecture✅—BytesBit key stays in URL fragment; OTS server can decrypt
Passphrase Protection✅✅Both support optional passphrase; BytesBit uses PBKDF2 600K iterations
Configurable TTL✅✅BytesBit: 30m–7d free. OTS free tier: up to 7 days
Bot / Link Preview Protection✅—BytesBit requires manual click to decrypt, blocking Slack/Teams bots
No Account Required✅—OTS requires sign-up for most features; BytesBit is fully anonymous
Generous Free Tier✅—OTS has paid tiers ($49–$149/mo); BytesBit offers a generous free tier
Open Source—✅OTS is open source; BytesBit is not (yet)
Custom Branding—✅OTS paid plans offer custom domains; BytesBit does not
API Access—✅OTS offers REST API on paid plans
Self-Hosted Option—✅OTS can be self-hosted; BytesBit is SaaS only

Encryption: The Fundamental Difference

BytesBit — True Zero-Knowledge

Your message is encrypted in your browser using the Web Crypto API (AES-256-GCM). The encryption key is placed in the URL fragment (#), which browsers never send to servers. Our server stores only encrypted ciphertext it physically cannot decrypt.

Even if our entire database were leaked, attackers would get nothing but random bytes.

OneTimeSecret — Server-Side Encryption

OTS encrypts your secret on their server before storing it. While they use strong encryption, the server does see your plaintext during the encryption process. This means OTS staff (or a compromised server) could theoretically access your secrets.

OTS mitigates this risk with good engineering practices, but it's a fundamentally different trust model.

Pricing

BytesBit — Generous Free Tier

BytesBit Secure Share offers a generous free tier with no account required. Core features — passphrase protection, configurable TTL, file attachments, bot protection — are all available at no cost.

OneTimeSecret — Freemium ($49–$149/mo)

OTS offers a free tier with basic features, but advanced capabilities like custom domains, API access, higher limits, and team features require paid plans starting at $49/month for Identity and going up to $149/month for Dedicated.
