Can I use the project's demo keys to get started?

For a quick local test only. For anything you keep running, register your own App so your usage is tied to your account and your limits.

Do I need a reverse proxy?

Strongly recommended. It handles TLS and gives you one place for rate-limiting and auth, which keeps tokens off the public interface.

In environment variables or a secrets manager, never in the repository. A leaked secret in git history is hard to fully remove.

How often should I update?

Whenever the project ships a release, especially one that mentions API changes. Subscribe to the repo's releases so you are not caught by a breaking change.

What is the lowest-maintenance option?

A single static binary like tcli. There is no runtime to patch, so you only manage keys and a scheduled run.

Self-hosting an open-source X client

Short answer

To self-host an open-source X client, create your own App in the X developer portal, store the client ID and secret in environment variables rather than the repository, run the app behind a reverse proxy that terminates TLS, and follow the project's releases so your copy stays current with API changes. Never reuse a project's demo credentials or commit secrets.

Key takeaways

Register your own App and use your own credentials, never the project's demo keys.
Keep the client ID and secret in environment variables, outside version control.
Put the app behind a reverse proxy for TLS, rate-limiting, and basic auth.
Track the repository's releases so API changes do not silently break your instance.

Running one of the clients from the Download page on your own machine is mostly about credentials and keeping current. Here is the checklist.

How do you set up credentials?

Register your own App in the X developer portal and keep its secret out of the repository. Do not reuse a project’s demo credentials. Store values in environment variables so they never land in version control:

# .env  (never commit this)
X_CLIENT_ID=your_id
X_CLIENT_SECRET=your_secret
REDIRECT_URI=https://yourhost/callback

The REDIRECT_URI must match a callback URL you register in the App settings exactly, or the OAuth flow will reject it.

How should you expose it?

Put the app behind a reverse proxy such as nginx or Caddy that terminates TLS. Forward to the app on localhost, and use the proxy as one place to add rate-limiting and basic authentication. This keeps the app itself simple and your tokens off the public interface.

How do you keep it working?

Watch the repository’s releases and pull updates regularly. When the X API changes, maintainers patch the client first, so an instance that never updates will drift into breakage. A single static binary such as tcli from the Download page skips most of this, since there is no runtime to maintain, just keys and a scheduled run.

Refresh tokens expire. If your client stores them, make sure it also implements the refresh flow, which the authentication chapter covers.
