## What it is
Bridgy Fed is an open-source bridge service that connects decentralized social networks, translating profiles, posts, likes, reposts, follows, and mentions between the fediverse (ActivityPub), Bluesky (AT Protocol), and IndieWeb sites (webmentions/microformats2). It runs as a hosted service at fed.brid.gy and can also be self-hosted as a Flask web app on Google Cloud.

## Use cases
- follow Bluesky users from my Mastodon account
- make my personal website visible on the fediverse
- cross-post between fediverse and Bluesky
- bridge my blog to ActivityPub so people can follow it
- reply to Bluesky posts from Mastodon
- connect IndieWeb site to AT Protocol
- translate ActivityPub to AT Protocol

## When to choose
- you want cross-network interactions between fediverse, Bluesky, and the open web
- you want a hosted, non-commercial bridge you can just sign up for
- you want to give a static website a fediverse/Bluesky presence via webmentions
- you need an open-source, self-hostable protocol translation layer

## When to avoid
- you need bridging for networks not yet supported like Nostr or Farcaster
- you want a full-featured client to log in and use a bridged account like a native one
- you need a simple cross-poster rather than a protocol-level bridge
- you want to bridge two existing accounts of yours into one
