W&B Self-Managed is a self-hosted deployment that runs in your infrastructure. Point the SDK and CLI at your instance URL instead of the Multi-tenant Cloud API (api.wandb.ai). For login commands, WANDB_BASE_URL, and --host, see wandb login and Environment variables.

​
Verify the connection

wandb status
Confirm the host matches your instance URL and the API key is present (masked).

​
SSL / certificate issues

If your instance uses a self-signed or internal CA certificate, set the CA bundle before initializing W&B: 
export REQUESTS_CA_BUNDLE=/path/to/ca-bundle.crt

​
Switching between Multi-tenant Cloud and Self-Managed

To use Multi-tenant Cloud again, unset WANDB_BASE_URL and run wandb login without --host: 
unset WANDB_BASE_URL
wandb login

​
Common issues

  • 401 on wandb.init(): API keys are not shared between Multi-tenant Cloud and a Self-Managed instance. Create a key on your Self-Managed instance profile.
  • Connection refused / timeout: Check the instance URL and VPN or network access to your deployment.
  • License not recognized: See Why is my enterprise license not recognized?.
