Instance switcher for self-hosted deployments

Steffen Schmitz

Switch between your Langfuse deployments from the sidebar user menu instead of keeping a list of URLs somewhere else.

This feature is available in the Enterprise Edition (self-host).

If you run more than one Langfuse deployment — development, staging, and production, or one per business unit — you can now configure them as a list and switch between them from the sidebar user menu. This mirrors the region switcher on Langfuse Cloud, so nobody has to keep deployment URLs in a spreadsheet.

LANGFUSE_UI_INSTANCE_LINKS='[{"name":"Staging","url":"https://langfuse-staging.example.com"},{"name":"Production","url":"https://langfuse.example.com"}]'

• The deployment you are currently on is marked in the menu, so you always know where you are.
• Entries open in a new tab. Sessions are not shared between deployments; each one authenticates on its own.
• The list is per-deployment configuration, so set the same value on every deployment to keep the switcher consistent.
