Purpose: Designed specifically for secure, ephemeral file sharing (such as secrets, environment files) and bigger files.
Benefits:
- Ephemeral Links: Files are available for a limited time or number of downloads, then deleted automatically.
- Big file transfer: Share up to 10gb files for free!
- No Account Required: Share files without making users register.
- No File History: Files are not stored long-term, reducing accidental leaks.
- End-to-End Security: Files encrypted end-to-end.
- No Metadata Leaks: Encrypted files and all data removed from the server upon download.
- Developer-Friendly: Tailored for secret sharing and developer workflows (e.g., sharing
.envfiles, config, secrets).
Purpose: Real-time chat and collaboration platform.
Drawbacks for Sensitive Files:
- Persistence: Files remain accessible in chat history unless deleted manually.
- Not Ephemeral: No built-in expiry or one-time-download.
- Limited Security Controls: Anyone with access to the channel can download files.
- Not Designed for Secrets: Risk of accidental leaks if channels are public or permissions are misconfigured.
Purpose: General cloud file storage and collaboration.
Drawbacks for Sensitive Files:
- Long-Term Storage: Files stay until you manually remove them.
- Link Sharing Risks: Shared links can be forwarded, and access controls can be tricky.
- Account Requirement: Recipients often need a Google account.
- Audit Trail: File access and edits are logged (can be good or bad for privacy).
- Not Ephemeral: No easy way to set file expiration or one-time download.
