Evidence vs Microsoft Power BI
Both are alternatives to Tableau. Here's how they stack up — verified facts, no spin.
Also searched as Microsoft Power BI vs Evidence — same comparison, one verdict.
Evidence is open source (MIT) and Microsoft Power BI is not (Proprietary (hosted service)) — so the real question is whether you want to own the bi & dashboards stack or rent it.
Evidence
Dashboards as Markdown and SQL, versioned in Git.
Evidence takes a genuinely different position: a report is a Markdown file with SQL in it, built into a static site. That means dashboards live in your repository, get reviewed in pull requests, deploy through CI and cannot be silently edited by someone in a UI. MIT licensed. It is the wrong tool for exploratory analysis and the right one for recurring, trusted reporting that has to be identical every month. Included because the BI category assumes a GUI is a requirement and for a good number of engineering teams it is the opposite.
Microsoft Power BI
A fifth of Tableau's per-seat price, if you are already on Microsoft.
Power BI Pro is about $14 per user per month against Tableau Creator's $75, and for organisations already inside Microsoft 365 the integration with Excel, Teams and Azure is genuinely deep. Listed here because refusing to name the obvious commercial alternative would be dishonest: for a Microsoft-shop finance department, Power BI is very often the right answer and no open tool changes that. The costs are the usual ones — proprietary, Windows-centric for authoring, and Fabric capacity pricing escalates sharply once you outgrow Pro.
Side by side
6 points of comparison, every one read from a verified field. Green marks the side that wins a row outright. A dash means we do not hold that fact — never that it is zero.

Evidence edges it on the Sovereignty Score, but the right pick depends on the trade-offs below.
Evidence
Strengths
- +Reports live in Git — reviewed, versioned, deployable through CI
- +MIT with no enterprise carve-out
- +Output is a static site: fast, cheap, nothing to keep running
- +Impossible to quietly alter a number without a commit
Trade-offs
- −No point-and-click building — you write SQL and Markdown
- −Not an exploration tool; it produces fixed reports
- −Non-technical staff cannot author
- −Small community
Microsoft Power BI
Strengths
- +Roughly a fifth of Tableau's per-seat cost
- +Deep integration with Excel, Teams and the Microsoft estate
- +Strong data modelling with DAX
- +Familiar to anyone who has used Excel seriously
Trade-offs
- −Proprietary and hosted; deepens Microsoft lock-in
- −Authoring is effectively Windows-only
- −Fabric capacity pricing escalates steeply at scale
- −Practically requires a Microsoft-centric organisation
Which one fits you
The trade-offs above, turned into a decision. Find the line that describes your team.
Choose Evidence
if you want the source and the option to fork it, and you would rather run it on your own hardware, and your data should stay on machines you control.
Choose Microsoft Power BI
if roughly a fifth of Tableau's per-seat cost.
Neither, yet
if both carry a real cost you should weigh first — no point-and-click building — you write SQL and Markdown, and proprietary and hosted; deepens Microsoft lock-in. If either of those is a dealbreaker for your team, the shortlist is wrong rather than the choice.
Evidence vs Microsoft Power BI — common questions
Is Evidence a better fit than Microsoft Power BI for bi & dashboards?
It depends on what you are optimising for, and the honest split is this: Evidence scores 94 to Microsoft Power BI's 28 on data ownership and exit cost, so it is the safer choice if you care about being able to leave. Microsoft Power BI earns its place on a different axis — roughly a fifth of Tableau's per-seat cost. Neither is a wrong answer for every team; the table above is the actual comparison.
What happens if we want to switch later?
Evidence keeps its data local or in open formats, so leaving is an export rather than a negotiation. Microsoft Power BI keeps your data on its own infrastructure, which is the part to plan for: confirm the export path before you commit, not when you are already trying to leave.
Is Evidence free?
Evidence: Free and open source. Evidence Cloud is an optional paid hosted tier.. The other side of this comparison, Microsoft Power BI, is priced as Power BI Pro about $14/user/month; Premium and Fabric capacity considerably more. Checked 2026-08-04.. "Free" here means no licence fee — if you self-host it you still pay for the server, and the running cost row above is our honest estimate of that.
Can I self-host Evidence?
Evidence can be self-hosted; Microsoft Power BI cannot, so it stays on the vendor's infrastructure whatever you do.
Are Evidence and Microsoft Power BI both alternatives to Tableau?
Yes — both appear in our Tableau comparison, which is why they are worth putting side by side. People usually arrive here already having decided to move off Tableau and now choosing between the two replacements, which is a narrower and much easier question.
