# VESSL Flare

If you're having trouble with your on-premises cluster, try using VESSL Flare. VESSL Flare collects all of the node's configuration and writes them to an archive file. It does not collect any sensitive information, including passwords, API keys, or strings. Send Flare key that appears after running VESSL Flare to [support@vessl.ai](mailto:support@vessl.ai).

VESSL Flare is [completely open source](https://github.com/vessl-ai/flare), so you can verify the behavior of the code.
