Third-party clients, mods and automating your account

Fluxer welcomes third-party and modified clients, themes and non-malicious automation of your own account.

Last updated on 12 November 2026

Fluxer welcomes third-party and modified clients, themes and custom CSS, and automating your own account, as long as you don't use them to harm others or the service. The Fluxer API has public developer docs, and the apps are open source under the AGPL.

Are third-party clients allowed on Fluxer?

Yes. You can use a third-party Fluxer client or a modified version of the official apps, and you can build your own. Only use clients from people you trust, because a client you sign in with can use your account and see everything you can see. A client you build can also be featured on our download page if it meets our standards for featured clients.

Can I automate my own account?

Yes. Non-malicious automation of your own account with your user token is allowed, for example a script that tidies your DMs. For a bot that other people use, a bot account is the better fit, because it keeps your own user token private from them.

Are themes and custom CSS allowed?

Yes. Themes and custom CSS are built into the web and desktop apps for everyone, with or without Plutonium, and you can share them with other people.

Will Fluxer always allow mods and themes?

We'll always allow modified apps, themes and custom CSS on fluxer.com, as long as you don't use them to break the community guidelines, for example to send spam, scrape people's data in bulk or get around bans, and other instances set their own rules. Our web and desktop apps stay on the web platform, where you can change them.

We accept pull requests that make modding Fluxer easier, and the contributing guidelines on GitHub list everything each pull request needs to include.

What isn't allowed?

The community guidelines apply whichever client or script you use. Spam, raids, scraping other people's data in bulk and evading bans, rate limits or moderation aren't allowed, whether you do them by hand or with a tool, and we can take action on your account for them. Using a third-party client, mod or script isn't against our rules by itself.
