Nullo vs Bitwarden Send
We are obviously biased here, but the comparison is still worth writing down. Bitwarden Send and Nullo solve the same problem: turn sensitive text into an encrypted link instead of pasting it into chat. They work the same way under the hood. Text encrypted locally, ciphertext uploaded, key kept out of server hands.

If you already use Bitwarden, use Send
Send lives inside the Bitwarden apps your team probably has installed: browser extension, desktop, mobile, web vault. No new vendor to approve, no new login to remember. Your billing and security habits carry over.
The downside only matters if you do not use Bitwarden. Then you are signing up for a password manager to get a sharing feature. Fine if you wanted a password manager anyway. Overkill if you just needed to send a staging password once a month.
If you want a dedicated link tool on Mac, that is us
Nullo does one thing: global hotkey, paste the secret, pick expiry and burn-after-read, copy the link. No vault, no autofill, no team admin console. Accounts are a 16 digit anonymous number, no email signup. Flat yearly price, unlimited links, pay by card or crypto.
Recipients open links in any browser. Creating links is macOS-only for now. Windows and Linux are on the roadmap but not shipped yet.
Quick comparison
| Feature | Bitwarden Send | Nullo |
|---|---|---|
| Primary UX | Inside Bitwarden apps | macOS menu-bar hotkey |
| Sender account | Email-based Bitwarden login | 16-digit anonymous number |
| Recipient | Browser | Browser |
| Pricing | Free for text Sends; file Sends need Premium or a paid org | Flat yearly subscription |
| Best for | Existing Bitwarden users | Dedicated secret-link workflow on Mac |
The honest summary
Already on Bitwarden? Send is the obvious pick. You have it, your team trusts it, done.
Need a fast dedicated workflow on a Mac and privacy matters? Nullo.
Need to create links from Windows or Linux today? Bitwarden, or wait until Nullo supports these platforms.
Either one beats pasting the secrets directly.
