Tweet Forker

What's this?

This is a "manual crossposter" that takes a given tweet's URL, fetches the necessary data and posts it to your Mastodon, Bluesky and Cohost account. This is useful to me because all the Twitter->Mastodon crossposters are either down, on the way out and/or don't properly support all of Twitter's features so I wanted a way to easily cherry-pick what tweets I wanted to cross-posts without too much overhead.

With the imminent demise of Twitter's API, this uses the API of FixTweet since I only need read access to a given tweet to work.

What works

• [x] Text tweets
• [x] Pictures
• [x] Videos (Mastodon only since neither Cohost nor Bluesky support them yet)

Non-goals

• Twitter Polls
• Twitter Circles
• Service-specific features like visibility settings/Content Warning on Mastodon

Setup

Requirements

• Node.js v18
• A server to run the process/expose it to the web
• Create a .env file by following the example in .env.example
• Run the following

npm install
npm run build
npm run serve

Docker

You will need Docker Compose npm run docker

How to use

Make a network request looking like this

curl "http://localhost:8080/u?secret=1234&url=https://twitter.com/foobar/status/123&services=mastodon,bsky,cohost"

I personally use an iOS/macOS shortcut that takes a tweet's URL, here it is: https://www.icloud.com/shortcuts/840875fdecaf497e8339260715771fda
