Workspace

- Overview: every item, model and report, with who reads what, including models in other workspaces.

- Lineage: data sources → semantic models → reports. Hover any card to trace its path.

- Consumption: how much of each model your reports actually use.

- Refreshes: a 24-hour schedule timeline that shows overlaps, success rates, and failures explained in plain English.

- Memory: each model against your capacity's per-model limit (and the ~2× a full refresh needs).

Semantic model (live over XMLA)

- Diagram of tables and relationships, and pipeline lineage from source query to report.

- Report usage: pages, visuals, slicers and filters per report, and every column and measure marked used in reports, model only or unused.

- Memory: size per table and column, what it's made of, and how much sits in unused columns.

- Refresh health and per-table freshness.

- Edit DAX and Power Query with IntelliSense and formatters. Every change is reviewed before/after, and nothing is written until you confirm.

Also: notebooks (edit, save, run), lakehouses (tables and files), Ctrl+K workspace search, light and dark themes.

Download (no install): grab Daxis-<version>-win-x64.exe or Daxis-<version>-linux-x64 from Releases and run it. Each release has SHA-256 checksums and build-provenance attestations (gh attestation verify <file> --repo AFetisa/daxis).

From source (needs the .NET 8 SDK):

git clone https://github.com/AFetisa/daxis.git

cd daxis

./run.sh # Linux, Git Bash

.\run.ps1 # Windows PowerShellgit pull, then run again to update. To build your own single-file executable: ./run.sh --publish (or .\run.ps1 -Publish), output in dist/.

Linux needs a desktop session. Minimal images and WSL may also need sudo apt install libice6 libsm6 libfontconfig1.

- A work or school account with access to the workspace.

- For semantic models: a workspace on Fabric, Premium or PPU capacity with the XMLA endpoint enabled (read-write to edit), and Contributor or higher.

- Report usage reads report definitions, which Fabric only allows with edit rights on the report.

- No Daxis server, no telemetry. Daxis only talks to Microsoft sign-in, Fabric, Power BI and OneLake.

- Tokens stay on your machine (DPAPI-encrypted on Windows, owner-only on Linux) and are never sent to any other host.

- Nothing changes in Fabric without your confirmation.

- Sign-in uses the Power BI Desktop public client. To use your own Entra app, set DAXIS_CLIENT_ID.DAXIS_HOMEmoves the data folder.
