Hey r/PowerBI,
I wanted to ask whether anyone here has gone down the rabbit hole of building custom Power BI visuals from scratch — not just using existing ones from AppSource, but actually creating .pbiviz files using the pbiviz toolchain (TypeScript, capabilities.json, the whole thing).
I'm curious about a few things:
What drove you to build one from scratch? Was it something AppSource simply couldn't offer, or were licensing/cost concerns involved?
How steep was the learning curve? Especially if you came from a pure BI/DAX background with little or no web dev experience.
What were the biggest pain points? (Format pane quirks, debugging inside Power BI, packaging issues, API limitations, etc.)
How has it held up long-term? Do you actively maintain it? Has anything broken after Power BI updates?
Would you do it again? Or would you look for alternatives first?
I ask because I've recently gone through this process myself.I'd love to hear from others who've been in the same position, especially people who've shipped something and are now living with the maintenance side of it.
Any insights, war stories, or lessons learned are welcome!
