What is it?

Visivo is a business intelligence tool where dashboards are defined as code. Data sources, models, a semantic layer of metrics and dimensions, insights, charts and dashboards are all written as YAML files that live in git. Changes can be reviewed as branches and pull requests, and a CI workflow can run queries and publish a preview stage.

Running visivo serve starts a local server that watches project files and rebuilds on save, with a browser workspace for exploring sources, drafting insights, laying out dashboards and committing changes back to YAML. Interactive inputs such as dropdowns and sliders filter charts in the browser through DuckDB-WASM, without querying the warehouse again.

Visivo also exposes an MCP server and a built-in agent. Both work over the same project definitions, and every write they make lands as a draft for the user to review before committing. The project supports PostgreSQL, MySQL, Snowflake, BigQuery, DuckDB, CSV and other sources, and offers dozens of Plotly chart types.
