Pinafore: a light Mastodon web client

Comments on Fediverse/Mastodon

Intro §

This blog post is for Mastodon users who may not like the official Mastodon web interface. It has a lot of features, but it's using a lot of CPU and requires a large screen.

Fortunately, there are alternatives front-ends to Mastodon, this is possible through calls between the front-end to then instance API. I would like to introduce you Pinafore.

What's Pinafore? §

Pinafore is a "web application" consisting of a static website, this implies nothing is actually store on the server hosting Pinafore, think about it like a page loaded in your browser that stores data in your browser and make API calls from your browser.

This design is elegant because it delegates everything to the browser and requires absolutely no processing on the Pinafore hosting server, it's just a web server there serving static files once.

As I said previously, Pinafore is a Mastodon (but also extends to other Fediverse instances whenever possible) front-end with a bunch of features such as:

- accessibility (for content warning content, greyscale mode, contrast, key bindings)

- only one column, it's really compact

- simple design, fast to load and doesn't eat much CPU (especially compared to official Mastodon interface)

- read-only support if you visit your Pinafore host when not connected, I find this very useful (remember that cache is stored in your browser)

- can handle multiple accounts at once

This being said, Pinafore doesn't target minimalism either, it needs javascript and a modern web browser.

How to use Pinafore? §

There are two ways to use it, either by using the official hosted service, or by hosting it yourself.

Whether you choose the official or self-hosted, the principle is the following: you enter your account instance address in it the first time, this will trigger an oauth authentication on your instance and will ask if you want pinafore to use your account through the API (this can be revoked later from your Mastodon account). Accept, and that's it!

Pinafore.social §

The official service is run by the developers and kept up to date. You can use it without installing anything, simply visit the address below and go through the login process.

Pinafore.social website

This is a very convenient way to use pinafore, but it comes with a tradeoff: it involves a third party between your social network account and your client. While pinafore.social is trustable, this doesn't mean it can't be compromised and act as a "Man In The Middle". As I mentionned earlier, no data are stored by Pinafore because everything is in your browser, but nothing prevent a malicious attacker to modify the hosted Pinafore code to redirect data from your browser to a remote server they control in order to steal information.

Self Hosting §

It's possible to create Pinafore static files from your system and host it on any web server. While it's more secure than pinafore.social (if your host is secure), it still involves extra code that could "potentially" be compromised through a rogue commit, but it's not realistic to encounter this case when using Pinafore releases versions.

For this step, I'll link to the according documentation in the project:

Trivia §

Pinafore is the recommended web front-end for the Mastodon server implementation GoToSocial which only provide a backend.
