The post screenshot tool for Mastodon. Developed by @[email protected]

Mastopoet is an open source screenshot tool for Mastodon, inspired by poet.so. It allows you to create ✨ stunning ✨ screenshots of your posts, with ability to remove stuff you don't want (bookmark button, publicity symbol, settings button...). And with a theme that's not dependent on the theme of the instance!

mastopoet.ohjelmoi.fi

Add ?url= to the end of the Mastopoet URL to generate links that immediately open the post on Mastopoet.

• Bird UI (Dark, Light)
• Mastodon (Dark, Dark + light interaction labels, Light)

This is due to CORS. I cannot do anything about it, as the whole process is done client-side.

If you want to get Mastopoet working on your instance, contact your admin and ask them to allow anonymous CORS (crossOrigin: "anonymous") requests for their Mastodon media server.

For admins this means they need to add the Access-Control-Allow-Origin header to the server providing your users with images hosted on Mastodon. You can set it to '*', or allow just Mastopoet with 'https://mastopoet.ohjelmoi.fi'. There's more technical information on MDN Docs.

You can use Docker (instructions below), or simply host the website on a static platform. Mastopoet is a React SPA, compiled by Vite, allowing it to be deployed to pretty much any hosting service. My recommendations are Cloudflare Pages, Netlify and Github Pages.

First, install dependencies with npm install and then build the app with npm run build. Simple as that! The application is in the dist directory.

By default, the default post shows a link to my Ko-fi profile. If you want to disable it, you can customize the defaultPost in src/config.ts, or set environment value VITE_HIDE_DEVELOPER_KOFI_AD to false. I appreciate if you decide to keep it.

You can use docker for deploying a production ready instance of Mastopoet.

You can build with:

docker build -t mastopoet .

It will build the application and deploy in an nginx instance, when the image is built you can run using:

docker run -d -p 80:80 mastopoet

For more options, see nginx container options at dockerhub
