Hi — great question! Here's what you need to know.

Key Thing to Know First

Currently, Databricks Apps (Streamlit, Dash, Gradio, etc.) listed on the Marketplace are first-party Databricks-owned apps only. External/partner app publishing is not yet supported but may come in the future. However, you can publish your work as a Solution Accelerator (Git-hosted), Notebook, or share the underlying data/models your app uses.

Steps to Become a Public Marketplace Provider

Prerequisites: Premium plan, Unity Catalog enabled, Account Admin access.

1. Apply via the Databricks Data Partner Program — select "Databricks Data Provider" as your interest. If you're already a Databricks Partner, email partnerops@databricks.com directly.
2. Once approved, the Provider Console becomes available in your workspace.
3. Create your Provider Profile (org name, logo, description, support email, terms of service, privacy policy).
4. Go to Provider Console → Listings → Create Listing — choose your asset type, set access model (instant or approval-required), add descriptions, categories, and sample notebooks.

Quick Tips

• Include sample notebooks — they significantly boost adoption
• Consider packaging your app as a Solution Accelerator if it's code-heavy
• You can test the flow first via a Private Exchange (no application needed) before going public
