The 12 Best Power BI Custom Visuals in 2026 (Free & Paid)

Four criteria, applied in order:

1. **Maintenance.** The visual shipped an update in the last 12 months. Report-breaking abandonment is the single most common failure mode for custom visuals — a visual that stops getting updates eventually breaks against a new Power BI API version, and your report breaks with it. 2. **Certification status.** Microsoft-certified visuals run sandboxed, cannot call external services, and support export to PDF/PowerPoint. Uncertified visuals are not automatically bad, but you need to know which one you are shipping to a tenant that blocks uncertified visuals. 3. **Formatting-pane depth.** A good custom visual behaves like a native one: full formatting cards, conditional formatting, theme support, cross-filtering. A bad one is a static image with data bound to it. 4. **Honest licensing.** Free means free, trial means trial, and per-user pricing is stated up front. Visuals that watermark or row-limit only after you have built the report around them did not make this list.

**Deneb** (free, certified, open source) is the most powerful custom visual on AppSource, full stop. It renders any Vega or Vega-Lite specification, which means practically any chart that has ever been drawn can be reproduced in Power BI. The cost is the learning curve: Vega-Lite is a declarative grammar you have to actually learn, and non-trivial charts take real time to specify. If your team has one person willing to own that skill, Deneb pays for itself many times over.

**HTML Content** (freemium, by Daniel Marsh-Patrick, the Deneb author) renders HTML from your data — rich text, styled cards, embedded SVG. It is the right tool when the "visual" you need is really formatted content rather than a chart.

**A note on Charticulator:** Microsoft retired it. The standalone app is archived and the visual is no longer developed. Do not start new reports on it in 2026 — migrate existing ones to Deneb or a generated visual.

**Zebra BI Tables and Charts** are the reference implementation of IBCS-style variance reporting in Power BI: actual vs plan vs prior year, waterfall bridges, small multiples, consistent notation. If your monthly reporting pack follows IBCS conventions, Zebra BI is the fastest path there. Licensing is per user, per month, on every report viewer — price that against your audience size before committing.

**Inforiver** goes beyond visuals into writeback and planning: editable matrices, what-if inputs, data entry back to a database. It is closer to a mini-application platform inside Power BI than a chart. Same caveat: per-user subscription licensing, tiered by capability.

Both are excellent software. The math to run before you commit: a visual priced per viewer per month, multiplied by a 200-viewer report, multiplied by every month the report lives, is a recurring line item that outlasts most dashboard redesigns.

**Sankey Chart by MAQ Software** (free, certified) is the standard pick for flow diagrams — customer journeys, budget cascades, energy flows. Three fields (source, destination, weight) and you have a working Sankey. Its limits: fixed palette control and shallow customization past three flow levels.

**ZoomCharts Drill Down Graph PRO** handles network and relationship data with genuinely good touch interactions and drill-down UX — the best-in-class option when stakeholders need to explore node-link data interactively. It is a paid per-user visual, with pricing tiers by feature.

If you need a flow or network visual that matches your exact brand and interaction spec, this category is also where generated custom visuals shine — flow layouts are well-understood algorithms, and owning the source means the palette, labels and drill behavior are exactly what you ask for.

**Gantt Chart by MAQ Software** (free, certified) remains the most-installed project timeline visual: tasks, phases, dependencies, percent-complete, today line. For a PMO status report it does the job with zero budget. The common complaints are label crowding on long task lists and limited conditional formatting on bars — livable for internal reports, visible in executive ones.

Craydec, xViz and Nova Silva all sell more polished Gantt/timeline visuals with per-user licensing if the free option's formatting ceiling becomes the blocker.

**Icon Map** (free, by James Dales) is the map visual Power BI should have shipped natively: WKT geometries, GeoJSON layers, custom tile servers, images and icons at coordinates, lines between points. It is the default answer for any mapping requirement beyond the built-in filled map — and it is free without a catch, which is rare in this category.

Three failure modes account for most custom-visual regret:

1. **Per-viewer subscription drift.** A visual priced per user per month looks cheap in a proof of concept with five viewers. The production report has three hundred. The invoice scales with your report's success and never stops. 2. **Silent deprecation.** Vendors retire visuals. OKVIZ deprecated Synoptic Panel v1 in March 2026; Microsoft retired Charticulator. When a visual you standardized on is deprecated, every report using it is now on a migration clock you did not schedule. 3. **Update-cadence risk.** AppSource visuals update on the vendor's schedule, and the version in your report updates whether you asked or not. A cosmetic change in a vendor release becomes an unreviewed change in your certified monthly reporting pack.

None of these are reasons to avoid custom visuals. They are reasons to know, per visual, who controls the code, what it costs at production scale, and what happens if the vendor loses interest.

The newest option on the list is not a marketplace visual at all. AI code generation made it practical to create a custom .pbiviz from a plain-English description: describe the chart, the palette, the interactions; get back a compiled visual plus its full TypeScript source.

Where this wins: brand-exact requirements no marketplace visual matches, per-viewer licensing you want off your invoice, and the long tail of chart types AppSource simply does not cover (try finding a maintained bowtie risk diagram or a Weibull probability plot). You own the source, so there is no vendor deprecation clock and no forced updates.

Where it does not win: generated visuals are not AppSource-certified (you import the .pbiviz directly or distribute it as an organizational visual), and maintenance is yours — which is exactly the trade some teams want and others do not. That is the honest framing: marketplace visuals rent you convenience; generated visuals sell you control.
