Signal

This tag covers Signal, the end-to-end encrypted messaging app, and why it has no official public API for third-party automated posting, unlike Telegram or Discord. It explains Signal's minimal-metadata design principles and why they're fundamentally at odds with the kind of bot infrastructure that would enable RSS-triggered auto-posting. Readers here are typically running privacy-focused communities on Signal and trying to understand whether automation is possible, including the risks of unofficial tools like signal-cli. It also contrasts Signal's approach with WhatsApp's official Business API, clarifying that encryption itself isn't what blocks automation. This is useful background for anyone deciding whether to build around an unofficial Signal integration or treat it as a deliberately manual channel.
