It doesn't say Toyota anywhere on the page and they don't have a link to a repo or anything like that, so I was a little confused. But it is from /that/ Toyota (well, a subsidiary that is making 3d software for their displays) and there was a talk at FOSDEM about it: https://fosdem.org/2026/schedule/event/7ZJJWW-fluorite-game-...

The combination of Flutter + Claude Code makes cross-platform app development really, really fast. I've been impressed with how well Clause handles prompts like, "This list should expand on the web, but not on iOS." I then ask it (Claude) to run both a web instance and an iOS simulator instance. Can usability test in-tandem.

I recently (as in, last night) added WebSockets to my backend, push notifications to my frontend iOS, and notification banner to the webapp. It all kinda just works. Biggest issues have been version-matching across with Django/Gunicorn/Amazon Linux images.

For others who were curious like I was: The website doesn't mention "open" or "source" anywhere, but they did give a talk at FOSDEM 2026 about it.

There was a passing comment about "when we open up the GitHub repository" in the talk. So it's not open yet, but they've suggested it might be in the future.

I wonder if a slightly broader search for existing solutions - for instance, https://defold.com - would have shown that quick-startup, 3d-capable, c-integrable, low-end-hardware performant game engines could have been grabbed off the shelf.

That said, this is cool and I would have probably celebrated a similarly fun project in their shoes. Perhaps the real accomplishment here is getting Toyota to employ you to build a new, niche game engine.

Filament is not a console grade renderer, not even close. It's architectured around GL. Yes, it can use Vulkan but it's not in any way optimized like a console engine.

Does it mean it also runs in a browser? Why isn't there a demo?

This definitely looks cool, flutter is still my tool of choice for small apps that aren't games, and I see a big company embrace it warms my soul.

Toyota assuming they move forward with this, might even become the main corporate sponsor since Google appears to be disinterested.

> console-grade

So... not PC-grade?

Interesting, they flipped the problem around.

The UI toolkits in game engine usually suck hard, so here they started from a good UI toolkit and made it possible to make relatively performant games.

Meh.

I've been burned by using closed source game engines before. There's just too many edge cases and nuances that come up when debugging physics or graphical issues. I strongly recommend against using this until they become at the very least source-available.

Now we’re talking. If Flutter is dying, how come I still see projects like this popping up instead of using native or KMP?

source code not available?

Interestingly this name (fluorite.game) is in the HaGeZi normal blocklist. https://adguardteam.github.io/HostlistsRegistry/assets/filte...

How is this related to Toyota? Toyota the car manufacturer?

Looked great. How is it associated with toyota?

Rust based ECS game engine, with 3,000 word diatribes about what decentralized, federated social media presence it should have, woefully incomplete, full of bugs, with no consideration of how any actual games are written other than Factorio, because that's the game that programmers who write open source game engines and not games play: "Aww, you're sweet"

Something about games authored by a giant company that will presumably actually ship in some products: "Hello, human resources?"

[flagged]

Not written in rust? No thanks

This trend of "complexity == moar gooder" makes me itchy. Why does a vehicle display system need a whole-ass game engine? I want my high-speed death box to have utilitarian, well-tested and well-written software, not fucking Unity.

Please stop, all this does is introduce new ways for things to break.
