Where SecretWolf falls short
An honest table beats a flattering one. Where OneTimeSecret does something SecretWolf doesn't, here it is:
- Onetime Secret is open source and can be self-hosted; SecretWolf is a hosted service only.
- Onetime Secret's free tier includes a custom domain and REST API; on SecretWolf those are Business-plan features.
- Onetime Secret can send a secret without the sender creating an account; SecretWolf needs a (free) account to send.
- Onetime Secret's paid plans also offer request links (“Incoming Secrets”), SSO and a security audit trail (beta, Team Plus).
