A Chromium web browser for Sailfish OS 5.1, built on Qt 6 QtWebEngine with a UI written from scratch in QML — not a fork of an existing browser. Part of the RooT* app family.

RooTitanium is tested on:
This application was developed using artificial intelligence technologies (Claude Code). Therefore, if the use of an application generated via a large-scale language model (LLM) is not comfortable for the user, it is recommended to avoid its installation and use. It is specified that any negative comment regarding this circumstance will not only be ignored but will result in the immediate blocking of the user.
I hereby disclaim any and all responsibility for the application, its functionality, and any consequences arising from its use. By choosing to use this application, the user acknowledges and accepts that they do so entirely at their own risk, and agrees that the developer shall not be held liable for any damages, losses, or adverse effects—whether direct, indirect, incidental, or consequential—resulting from the use or misuse of the application.
On Sailfish OS, Qt 6 is not an official platform component, and qt6-qtwebengine is not precompiled anywhere. RooTitanium therefore ships a self-contained bundle: the whole Qt 6 + QtWebEngine runtime (Chromium 122) is compiled from source over the community Qt 6 stack and installed under /home/rootitanium/, so the app needs no system Qt 6 and does not interfere with the platform.
The RPM payload goes to /home/rootitanium/ (the /home partition), while the .desktop, icons and the ELF launcher go to the rootfs under /usr. Conventions shared with the RooT* family: package harbour-rootitanium, version single-sourced from the spec.
RooTitanium renders pages with Qt 6 QtWebEngine (Chromium 122), bundled as described above and in NOTICE.md. For site compatibility the browser presents itself as Google Chrome through a Client-Hints / user-agent interceptor; this is identification only and does not make it a Google product.

RooTitanium è testato:
Questa applicazione è stata sviluppata utilizzando tecnologie di intelligenza artificiale (Claude Code).

Su Sailfish OS, Qt 6 non è un componente ufficiale della piattaforma, e qt6-qtwebengine non è precompilato da nessuna parte. RooTitanium distribuisce quindi un bundle self-contained: l'intero runtime Qt 6 + QtWebEngine (Chromium 122) è compilato dai sorgenti sopra lo stack Qt 6 della community e installato sotto /home/rootitanium/, così l'app non richiede alcun Qt 6 di sistema e non interferisce con la piattaforma.
Il payload dell'RPM va in /home/rootitanium/ (partizione /home), mentre il .desktop, le icone e il launcher ELF vanno nel rootfs sotto /usr. Convenzioni condivise con la famiglia RooT*: pacchetto harbour-rootitanium, versione single-source dallo spec.
RooTitanium mostra le pagine con Qt 6 QtWebEngine (Chromium 122), impacchettato come descritto sopra e in NOTICE.md. Per compatibilità con i siti il browser si presenta come Google Chrome tramite un interceptor di Client-Hints / user-agent; è solo identificazione e non lo rende un prodotto Google.

Changelog <1.2:
- Some issue with heavy social like X.com;
- No DRM.
- Mobile file picker (3db7d2e) — the file upload (<input type=file>) now opens a full‑screen native picker instead of the tiny desktop dialog: Home/Download/Images/Documents/Video shortcuts, folder navigation, multi‑selection with checkmarks, and an Upload button.
- Reading Mode (69f8dee) — in the ⋮ menu: extracts the article using Mozilla’s Readability.js and displays it with serif typography on light/dark theme; A−/A+ buttons (size is remembered) and ✕ to return to the article exactly where you left off.
- Accept-Language from actual locale (7375cff) — websites no longer force Italian on foreign devices; neutral fallback en_US via SSH.
- Two‑finger pinch zoom (99cdcb0) — mobile page‑scale pipeline enabled (--enable-viewport); internal pages locked at scale 1.
- Keyboard (3dab90e) — long language names (“norsk bokmål”) now fit inside the space bar instead of overflowing.

RPM 1.2-1 indeed. I have OKBoard running, homescreen automatic. Disabling these changes nothing.
However, I noticed that I installed Qt Runner, as a basis for Noson. This might interfere!? Anyway, Qt Runner may have interesting stuff for you: connection to SFOS keyboard instead of Qt keyboard

Interesting development. Strange that on X10iii 5.1.0.11, I can only use a part of the screen. Let's say only the part not covered by the SFOS keyboard. Then, the Qt6 keyboard takes a part as well, resulting in 40% browser visible

That's strange because I've X10III too and I don't have the same bug.
Three things would help me pin it down:
- the RPM version (rpm -q harbour-rootitanium) — it might not be 1.2-1;
- does it happen right at startup, or only after you tap the URL bar for the first time?
- do you have an alternative system keyboard installed, or homescreen rotation enabled?

How do you intend to block complaining users as specified in the release notes? :) My complain is not about Claude but about the gas powered data center over which it runs and polluting Memphis and the rest of the world...

By "blocking" I just meant ignoring. What I mean in the app description is: criticism about the fact that I use AI (Claude Code, in my case) gets ignored or deleted. Any other constructive comment or request gets considered, exactly as I've always done.
That said, since you asked it politely, I'll answer once. The Memphis gas turbines are xAI's (Colossus), not Anthropic's. Claude runs on AWS/GCP infrastructure. But that's just a correction, not a defense: data centers burn a huge amount of energy and will burn more, whoever runs them.
The problem doesn't go away.
What I can say about this project: it's a small SailfishOS browser, and the AI assistance amounts to a handful of dev sessions. Without it I'd have taken a thousand times longer, or simply wouldn't have been able to build it at all. So I'm not claiming "the energy would have been spent anyway": I'm saying this app exists because of that energy, and to me it's worth spending it on something like this, rather than on making kittens sing...
I don't think that settles the ethics, but that's where I stand.

Surprisingly it seems more memory lightweight than the other Sailfishos browsers.
I think it would be amazing one day to read an article on your LLM empowered workflow for sailfish development as at this point you released a lot of content

Great UI, very precise and smooth rendering. One issue - some websites default to Italian language, please fix. Jolla C2, will soon test on the new Jolla 2.

Just tried it with a few sites. Perfect rendering and very smooth scrolling. Is it possible to get native on-screen keyboard? I need Norwegian keymap (æøå)...

Unfortunately not. The native SFOS keyboard is based on Qt 5 (maybe 5.6, I’m not sure) and Chromium only runs on Qt 6. I had to create an environment suitable for Qt 6, and the native keyboard wouldn’t run in it. Anyway, the Norwegian layout is already present: you need to tap the keyboard’s globe icon and select “Norsk Bokmål”.
If you like my app, I invite you to rate it. I’m asking because there’s someone who enjoys giving 1 star to all my apps no matter what. Probably someone who hates AIs…

Well, I am not one of them. But I am not sure where I currently standing. I prefer human coded apps, but I admit that AI is the future also for open source projects. Torvald Linus just nailed it: https://www.theregister.com/ai-and-ml/2026/07/15/linus-torvalds-tells-ai...
The important thing for me is: The code should be available, readable, understandable and maintainable. It means that it should follow coding styles of a project or for the platform. That gives me the needed security that there is not a hidden backdoor in the app. I have no idea who you are, and as a enduser, I cannot read your code and most likely no devs will take the time to review your code. This is a lack of trust and not that you have used AI.
Another issue is that I have a feeling that most AI code seems bloated. File sizes are considerably bigger then when humanly coded.

Any reason for calling it Norsk bokmål? Could it be only called Norsk? Norsk would fit in to the space bar...
