Fixie documentation
Static IP guides by language, platform, and destination
Start with the exact path your app needs: choose a runtime, where it runs, and the service it connects to. Every guide below is written for its specific stack — Fixie routes outbound traffic through stable IP addresses for API allowlisting, database connections, and SFTP transfers.
