Fulguris

Overview

Fulguris is a free, open-source browser for Android built around named tab sessions and configurable privacy tools. It suits people who want to keep browsing contexts separate and adjust ad blocking, bookmarks, and page display to their preferences. Its strongest distinction is session management; the main choice is which release channel’s tab terms and diagnostic behavior fit you.

Key features

Named sessions let you group tabs and switch between sets, a useful way to keep separate browsing tasks organized. The browser pairs that with vertical and horizontal tab views and a combined address, title, and search bar, giving users two ways to navigate a tab-heavy setup.

The built-in ad blocker accepts Fulguris definitions as well as local and online hosts files, which gives users control over the lists they use. Privacy controls include incognito mode, discarding tracking cookies, and clearing tabs, history, cookies, and caches. These are practical controls for managing browsing data, though they do require the user to choose and apply them.

Bookmarks can be imported, exported, arranged in folders, and backed up or restored through cloud services. Search options include Google, Bing, Yahoo, StartPage, and DuckDuckGo, with suggestions from Google. Reader mode and inverted, high-contrast, and grayscale rendering modes add useful flexibility for reading and display preferences.

Orbot Proxy and I2P support are beta, so they are better treated as experimental integrations than a reason to choose the browser for dependable proxy or I2P use. Location, camera, and microphone permissions are requested only when needed and only with the corresponding browser options enabled.

Pricing

Fulguris is free and open source. The Download / F-Droid plan costs nothing and provides unlimited tabs without a subscription. It is the clearest fit for users who want unrestricted tab capacity without recurring payment.

The Google Play plan has no stated price. A yearly subscription is suggested after more than twenty tabs in a session, so users who regularly exceed that threshold should compare its terms with the unlimited-tab direct download and F-Droid builds before choosing a channel.

Platforms

Fulguris runs on Android, with mobile as its supported platform. Public release channels are Google Play, direct download, and F-Droid. Google Play and direct download builds may send optional Firebase statistics and crash reports; the F-Droid build does not. The project describes itself as a very small operation and places release testing and validation with the community, a consideration for readers who prioritize a larger release operation.

Who it's for

Fulguris is a strong fit for Android users who organize browsing into separate activities, want built-in ad blocking with configurable host lists, or value granular controls for clearing browsing data. Its bookmark transfer and backup options will also suit people who manage a substantial collection across folders.

Look elsewhere if you need a browser across desktop and mobile, or if experimental integrations are not suitable for your needs. Readers who want unlimited tabs should choose direct download or F-Droid; those choosing Google Play should account for the subscription prompt beyond twenty tabs in a session.

Pros and cons

• Pros: Named sessions and two tab layouts give tab-heavy browsing meaningful organization options.
• Pros: The ad blocker accepts its own definitions and local or online hosts files.
• Pros: F-Droid and direct download provide unlimited tabs without a subscription.
• Cons: Google Play suggests a yearly subscription after more than twenty tabs in a session, with no exact price stated.
• Cons: Orbot Proxy and I2P support are beta, limiting their suitability for users who need stable integrations.
• Cons: The project relies on the community to test and validate releases.

Alternatives

Mozilla Firefox is a better fit for readers who want a free, open-source browser across Android, iOS, desktop systems, and the web. Bare Browser may suit Android users comfortable with an alpha release; it targets Android 10+ and ARM 64-bit or 32-bit builds, while Google Play and F-Droid are marked as coming soon.

SmartCookieWeb is another free, open-source Android option, described as completely free and ad-free. SquareBrowser instead fits readers willing to accept daily browsing limits of up to six hours and a Strict Mode lock until midnight.

Google Chrome, Microsoft Edge, Opera, and Ecosia Browser are also listed as alternatives.

Verdict

Its free F-Droid and direct download builds make unlimited tabs straightforward, while Google Play’s subscription prompt and the project’s community-led release validation are meaningful trade-offs. For multi-platform browsing, Firefox is the stronger alternative; for tab organization on Android, Fulguris makes a focused case.
