Helium Browser Review 2026: What It Is and Who It’s For

If you’ve seen “Helium browser” mentioned next to ungoogled-chromium or privacy-focused forks, you’re probably wondering what it actually is and whether it’s worth installing. Short version: Helium is a free, open-source, Chromium-based browser that strips out Google’s service dependencies and blocks ads, trackers, and fingerprinting out of the box. It’s made by a small team called Imput, funded by user sponsorships rather than ads or subscriptions.

This review sticks to what Helium’s own site, GitHub, and privacy policy say, dated as of September 2026 since beta software changes fast. We’ll cover what it’s built on, who makes it, what devices it runs on, how it handles extensions and privacy, and (since this is a tab-safety blog) what happens to your tabs if you decide to try it.

What Is Helium Browser?

Helium is a free, open-source, Chromium-based desktop browser with Google’s service dependencies removed. According to Helium’s own homepage, it’s “a Chromium-based browser, with all Google service dependencies removed,” and its GitHub README adds that it’s derived from ungoogled-chromium but heavily modified for Helium specifically.

Here’s the shape of it at a glance, all pulled from Helium’s own pages as of September 2026.

That table is the whole story in miniature: a stripped-down Chromium with privacy defaults turned on, built by a small team, still labeled beta, desktop-only. Everything below fills in the reasoning behind each row.

Who Makes Helium Browser and How Is It Funded?

Helium is developed by Imput, a small outfit that funds the project through user sponsorships rather than a traditional business model. That’s a meaningfully different setup from browsers backed by ad revenue, a search-engine kickback deal, or venture funding. There’s no advertiser relationship to protect, and no obvious reason to soften privacy defaults for a partner.

The trade-off is scale. A sponsorship-funded, small-team project doesn’t have the release cadence, support staff, or long-term guarantees of a company like Google or Microsoft. That’s not a knock on the work (plenty of respected open-source software runs this way) but it does mean you should expect a slower pace on bug fixes and a smaller community if you hit an edge case.

The code itself lives in the open: Helium’s GitHub project is maintained under the imputnet organization, and the older repository path automatically redirects to the current one, which is a normal sign of an actively maintained project rather than an abandoned rename. If you like to verify claims yourself before trusting a browser with your daily tabs, that repository and Helium’s own site are the two places to check.

What Browser Engine Does Helium Use?

Helium runs on Chromium, specifically a heavily modified fork of ungoogled-chromium. Ungoogled-chromium itself is a community project that takes Google’s open-source Chromium code and strips out ties to Google’s own services — things like Safe Browsing pings and other background connections back to Google.

Helium starts from that base and, per its GitHub README, modifies it further for its own purposes. That lineage matters practically: because the rendering engine is Chromium, most websites built and tested against Chrome should behave the same way in Helium, since they share the same core rendering and JavaScript engine. It also means Helium inherits Chromium’s extension architecture, which is the reason it can support Chrome Web Store extensions without a separate compatibility layer.

If you’re coming from Chrome, Edge, Brave, Opera, or Vivaldi, the underlying engine will feel familiar even if the branding and default settings are different. If you’re coming from a Gecko-based browser like Firefox, or comparing against Firefox-based projects such as our Zen Browser review or our Waterfox browser review, keep in mind the engine family is a real difference — extensions, rendering quirks, and some site behaviors won’t carry over identically between Chromium and Gecko browsers.

Is Helium Browser Free and Open Source?

Yes, Helium is free in both price and license. Its own homepage FAQ confirms it’s free “both in terms of price and freedom,” describing itself as FOSS — free and open-source software.

On the licensing side, Helium’s own code is released under GPL-3.0. The portions it imports from ungoogled-chromium keep their original BSD-3-Clause license, which is standard practice when a project builds on top of another open-source codebase rather than rewriting everything from scratch.

Being open source doesn’t automatically make a browser more trustworthy — plenty of closed-source browsers are perfectly safe, and plenty of open-source projects go unmaintained — but it does mean anyone can read the code, audit the privacy claims, or fork the project if Imput ever stops maintaining it. For a small, sponsorship-funded browser, that openness is a reasonable form of insurance against the project quietly changing its privacy behavior later.

Which Devices and Operating Systems Does Helium Browser Support?

Helium runs on macOS, Windows, and Linux only. There’s no mobile version. Specifically, it needs macOS 13 Ventura or newer, Windows 10 or newer, and on Linux it offers packages for Fedora via dnf, Debian and Ubuntu via apt, plus a generic AppImage and tarball for other distributions.

Automatic updates are handled for you on macOS and Windows. Linux users update through whichever package manager they installed Helium with, which is normal for Linux software and gives you more control over exactly when updates land.

On mobile, Helium’s own site is direct about it: support is “not yet” available. If most of your browsing happens on a phone or tablet, Helium simply isn’t an option today, and there’s no roadmap date to point to — “not yet” is as specific as the vendor gets.

Those three are worth a look if Helium’s Chromium base or desktop-only limitation doesn’t fit what you need — all three have their own trade-offs, covered in the linked reviews.

How Do You Download and Install Helium Browser?

You install Helium the same way you’d install most desktop software: download the right package for your operating system from Helium’s own download page, then run the installer or package-manager command.

1. Open the official download page. Go to helium.computer/download rather than a third-party mirror, since Helium is a small project and you want the vendor’s own binary.
2. Pick your platform. macOS needs version 13 Ventura or later; Windows needs version 10 or later; Linux users choose dnf (Fedora), apt (Debian/Ubuntu), or the AppImage/tarball for anything else.
3. Run the installer. Follow the normal install flow for your OS. There’s nothing Helium-specific about this step.
4. Confirm updates are working. macOS and Windows update automatically in the background; on Linux, updates come through your package manager, so make sure that’s configured.
5. Set your default browser once you’re comfortable. Don’t rush this — test your daily sites and extensions first, since Helium is still in beta.

Before you make Helium your daily browser, it’s worth saving a full backup of whatever tabs you currently have open elsewhere. That’s a good habit any time you try a new browser, not just this one — see our guide on alternative browsers for Chrome for more on switching without losing work.

Does Helium Browser Block Ads, Trackers, and Fingerprinting?

Yes, by default, without needing to install a separate extension. Helium’s own homepage states plainly: “Helium blocks ads, trackers, cookie banners, third-party cookies, and tampers with fingerprinting. By default.”

The ad-blocking engine underneath is a fork of uBlock Origin, according to Helium’s GitHub README. That’s a meaningful detail, since uBlock Origin is widely regarded as one of the more effective and lightweight filtering engines, and building it directly into the browser means you’re not relying on the Chrome Web Store keeping a separate ad-blocker extension alive and up to date.

On fingerprinting specifically, Helium’s homepage says the browser “noises certain web APIs to make your browser harder to fingerprint and track.” That’s a specific, verifiable claim rather than a vague privacy slogan, though Helium doesn’t publish a fingerprinting-resistance benchmark the way some dedicated anonymity tools do.

Beta software, beta bugs. Aggressive default blocking can occasionally break a site’s login flow, checkout page, or embedded widget. If something stops working in Helium, try disabling the blocker for that one site before assuming the site itself is broken.

Can You Use Chrome Extensions in Helium Browser?

Yes. Helium’s own homepage states it “supports all Chromium extensions by default,” which points to compatibility with the Chrome Web Store since Helium shares Chromium’s extension architecture.

This is one of the more practical upsides of building on Chromium instead of a from-scratch engine: you don’t lose your extension library when you switch. If you rely on a password manager, a note-taking clipper, or a tab manager in Chrome today, there’s a reasonable chance the same extension installs cleanly in Helium, since the underlying extension APIs are the same family covered on our Chrome browser page.

That said, “supports all Chromium extensions” is a statement about compatibility, not a guarantee that every extension behaves identically once Google-specific services are stripped out underneath it. An extension that leans on a Google-hosted API for part of its function could behave differently in a browser built specifically to avoid those dependencies. If an extension misbehaves, it’s worth checking whether it depends on any Google service before assuming Helium itself is at fault.

How Private Is Helium Browser? What Data Does It Collect?

Helium’s stated approach is to make no network requests beyond what you trigger yourself. Its own privacy policy says it “does not make any network requests… unless such requests are the result of user actions… or are part of features that the user has explicitly enabled,” and that all browsing data managed by Helium “is stored locally on your device,” with neither Imput nor other maintainers able to access it.

Crash reporting works on an opt-in basis only. If you consent to send a crash report, Helium’s privacy policy says the technical data is retained for up to 30 days — a specific, bounded window rather than an indefinite retention policy.

A few things aren’t addressed anywhere on Helium’s own pages as of this writing: sync-account support and exactly what happens to your open tabs when you relaunch the browser. Rather than guess, treat both as unconfirmed. If cross-device sync of tabs, passwords, or history is a requirement for you, don’t assume Helium has it just because most modern browsers do — check Helium’s own site directly before relying on it.

Is Helium Browser Worth Switching To? Limits and How BelayTab Fits In

Helium is worth trying if you want a Chromium-based browser with meaningful ad, tracker, and fingerprinting defenses turned on by default, and you’re on macOS, Windows, or Linux. It’s a reasonable pick for someone who wants Chrome-style extension support without Google’s services running in the background, and who doesn’t mind that it’s still labeled beta.

It’s not a fit if you need it on your phone. There’s no Android or iOS build and none is promised on a timeline. It’s also not the right choice if cross-device sync of tabs and passwords is non-negotiable for you, since that isn’t confirmed anywhere on Helium’s own site. And because it’s beta software from a small, sponsorship-funded team, expect the occasional rough edge that a larger vendor might catch before shipping.

If you do want to try it, a gradual test beats an all-at-once switch, especially while it’s still labeled beta.

Here’s where BelayTab fits into that picture honestly: BelayTab currently supports Chrome, Edge, Brave, Opera, Vivaldi, Arc, Firefox, and Safari on Mac. Helium is not on that list, so BelayTab can’t save or restore sessions inside Helium itself, and I won’t pretend otherwise. What it can do is protect the tabs in whichever supported browser you’re moving from while you evaluate Helium — automatic snapshots every 5 minutes and on window close mean you’re never one accidental quit away from losing your open windows during the switch. If Helium turns out to be your daily driver, keep a supported browser like Chrome or Firefox around for anything you want that safety net on; if you go back, your sessions and version history are waiting via BelayTab’s recovery screen.

Where BelayTab helps. If your daily browser is Chrome, Edge, Brave, Opera, Vivaldi, Arc, Firefox, or Safari on Mac, BelayTab’s automatic snapshots and session saving mean a crash, an accidental window close, or a browser switch never costs you your open tabs. Download BelayTab free for any of those browsers.

Frequently Asked Questions About Helium Browser

A few quick answers to the questions people ask most before installing Helium, gathered here since they didn’t fit neatly into the sections above.

Is it actively maintained? Yes — the GitHub project shows recent releases up through version 0.18.1, and the fact that an old repository path redirects to the current one is itself a sign of ongoing upkeep rather than abandonment. Should you use it as your only browser? That depends on your tolerance for beta software and your need for mobile or sync support — if either of those is a hard requirement, wait or use Helium alongside a browser that covers that gap. Is it a rebrand of ungoogled-chromium? No. It’s built from that codebase but modified further, with its own ad-blocking fork and fingerprinting defenses layered on top, so treat it as a distinct project with a shared ancestor rather than a simple reskin. See the full FAQ list above for more specific questions, including data collection, extensions, and what happens to your tabs if you decide to switch back to a browser you were using before.
