Additional context
guilded.gg is a Discord alternative that's turning some heads, but right now the bot api isn't available to the public. I think people would like this.

I should like to add that Guilded claims to support the Discord webhook API, as touted in the webhook scene of each channel's settings.

The API is available now.

Bump; the other bridge bots I can find that support Guilded are either feature-poor or discontinued.
