Fluid alternatives: what you can drop

The closest free alternatives to Fluid, the Mac app that turns a website into a standalone app, are already on most Macs: Safari's Add to Dock on macOS Sonoma 14 or later, and Chrome's Install page as app. For the features those two lack, such as userscripts, link rules or several accounts on one service, the maintained paid options are Unite Pro and Coherence X6, both from 39.99 USD per Mac and both requiring macOS 15. Fluid itself still downloads from fluidapp.com, but the build it serves is version 2.1.2, signed in October 2018 and compiled for Intel only. Apple has said that Rosetta, which lets Intel apps run on Apple silicon, will be limited after macOS 27. That is the real reason to plan a move now. The sections below check each fact against the vendor's own page as of October 18, 2026, and show how to decide which Fluid features need replacing at all. This site is published by the maker of Kagemusha, another tool in this category, and the comparison sticks to published facts.

Where Fluid stands in October 2026

The official site still offers the download and states the terms plainly.

A 5 USD licence unlocks three extras: pinning an app to the menu bar status area, userscripts and userstyles, and full screen mode. The download page describes the app as a 6.3 MB download requiring Mac OS 10.12 or later.

Inspecting the downloaded file on October 18, 2026 shows four facts that matter more than the price:

• The version is 2.1.2. The changelog lists 2.1.2 as the newest entry, a single fix to the bookmarks bar.
• The code signature is timestamped October 20, 2018. No newer build has been published since.
• Every executable is Intel only. Both the Fluid creator and the template it copies into each new app report a single x86_64 architecture.
• It is notarized. macOS accepts it as a notarized Developer ID app, so it still opens on a current Mac without a Gatekeeper block.

The Intel point is the one with a date attached. Apple's support article on Rosetta and the transition to Apple silicon states that Rosetta is available on Apple silicon Macs running macOS 27 or earlier, and that from macOS 28 it will be available only for certain older, unmaintained games that rely on Intel frameworks. Fluid apps are not games, so on macOS 28 they should be expected to stop opening on Apple silicon. Nothing breaks this morning, but the end is now scheduled.

Break a Fluid app into the jobs it does

A Fluid app does several unrelated jobs at once, and they do not all need the same replacement. Listed separately:

1. A Dock icon of its own, visible in Command Tab
2. A window without the clutter of a full browser
3. Cookies and logins kept apart from the everyday browser
4. Rules that keep some links in the app and send others to the default browser
5. Userscripts and userstyles that change the page as it loads
6. Pinning to the menu bar, with a global keyboard shortcut to summon it
7. A changeable user agent, so the site sees a different browser

The first three are standard on a current Mac and cost nothing. The other four are where migrations go wrong. Someone who checks only the first three, moves everything to a free route, and then finds on the fourth day that a userscript was quietly fixing an internal admin page has done the work twice.

The quickest way to tell which group applies is to open the preferences of each Fluid app and look for settings that differ from the defaults. If only the general settings were ever touched, the app was only providing the first three jobs, and a free route will replace it fully.

User agent switching is usually safe to drop. The presets in a 2018 build describe browsers from 2018, and presenting a current site with a browser string that old tends to cause more sign in refusals than it prevents. The default setting, which reports the running system, is the one most setups were using anyway.

The free routes already on a Mac

Before any tool, check whether the service now ships an official Mac app. If it does, the wrapper question disappears. If not, two free routes cover the first three jobs completely.

Safari, Add to Dock. On macOS Sonoma 14 or later, open the page in Safari and choose File, then Add to Dock. Apple's support article states that the resulting web app shares no browsing history, cookies or website data with Safari, can have any name and icon, can show unread notification counts on its Dock icon, and can run Safari extensions that are enabled for it. It uses the same WebKit engine Fluid used, so pages render the way they did in a Fluid app.

Chrome, Install page as app. In Chrome, select the three dot menu, then Cast, save, and share, then Install page as app, as described on Chrome's Use web apps page. The app opens in its own window with its own Dock icon and is managed at chrome://apps. It shares the cookies, logins and extensions of the Chrome profile that created it, so two accounts on the same service need two Chrome profiles.

Neither route depends on Rosetta, and neither costs anything. What they do not provide is link rules, userscripts in the Fluid sense, or menu bar pinning. Safari's extension support covers some of the userscript cases, since userscript managers exist as Safari extensions, but that should be tested with the actual script before relying on it.

The paid tools that cover the rest

If one of jobs four to six is load bearing, a dedicated tool is the answer. The figures below come from each vendor's official page on October 18, 2026.

	Fluid 2.1.2	Unite Pro	Coherence X6	Kagemusha
Price	Free, 5 USD for extras	From 39.99 USD per Mac	From 39.99 USD per Mac	Free for 3 apps, 24.99 USD one time
Free tier	Unlimited apps	First app free	One app, no time limit	Three apps, all features
macOS required	10.12 or later	15 or later	15 or later	12 or later
Apple silicon	Intel only	Native	Native	Native
Engine	System WebKit	WebKit	An installed Chromium browser	An installed Chromium browser
Last release	October 2018	Current	6.1, September 2026	Current

Unite Pro and Coherence X6 are both made by BZG Apps. Unite builds WebKit based apps, closest to how Fluid worked. Coherence builds apps on Chrome, Brave, Edge, Vivaldi, Helium, Chromium or Ungoogled Chromium. The Unite purchase page lists 39.99, 59.99 and 99.99 USD tiers, states macOS 15 and later, and mentions a 14 day refund window. The Coherence changelog records that X6, released September 8, 2026, requires macOS 15 or later and replaced the old 14 day trial with one free app with no time limit. Both are also available through Setapp, which the BZG pages list from 9.99 USD a month.

The last column describes the tool made by this site's publisher. According to its own pricing page it runs on macOS 12 or later, builds each app on one of seven installed Chromium browsers with its own isolated profile, supports Chrome Web Store extensions per app, and ships more than 300 service presets, which can be browsed on the Supported services page.

Read the table for prerequisites first and price second. The macOS row removes options outright: a Mac that cannot run macOS 15 cannot run either BZG tool, whatever it costs. The engine row decides how sites render. WebKit tools behave like Safari, and Chromium tools behave exactly like the browser they borrow, which helps with internal consoles tested only in Chrome.

Matching each Fluid feature to a replacement

With the inventory done, each feature has a short list of answers.

Separate logins for two accounts on one service. Safari web apps each keep their own data, so two web apps for the same site can hold two accounts. Chrome needs two profiles. The Chromium based paid tools give each app its own profile automatically.

Link rules. Coherence X6 documents per app link routing that can keep links in the app, send them to another app, or open them in a chosen browser, and its 6.1 release added several domains per rule. Users of a carefully tuned Fluid whitelist should look here first.

Userscripts and userstyles. On Safari, test whether a userscript extension runs the script inside the web app. On Chromium based tools that accept Chrome Web Store extensions, a userscript manager extension can be installed in just the one app that needs it.

Menu bar pinning with a summon key. This is the hardest Fluid feature to reproduce, and none of the free routes offer it. Confirm it in a paid tool's free tier before buying, rather than assuming.

Full screen. Every route above opens a normal macOS window, which supports full screen without any licence.

Moving apps over in an order that shows problems

Rebuilding everything in one sitting makes it impossible to tell which change caused which problem. Order the work instead.

Start with the simplest daily app, one whose sign in does not pass through a company identity provider and which uses no scripts. Rebuild it with Safari or Chrome and use it for a week. If nothing is missing, the other simple apps will behave the same way.

Next, move anything that signs in through a work account or single sign on. Right after rebuilding, complete a full sign out and sign in inside the new window, and check that the login does not end up stranded in a browser tab.

Leave the apps that depend on scripts, link rules or menu bar pinning for last, and accept a paid tool for that group alone if needed. Mixed setups, with free routes for most apps and a dedicated tool for two or three, are common and stable.

Before choosing any replacement, run the same four checks that exposed Fluid. Look for the date of the last release. Select the app in the Finder, press Command+I, and read the Kind field to see whether it is Apple silicon, Universal or Intel. Check the macOS requirement against the Mac that will run it. And confirm the tool is still sold, not just listed.

What to change first

Open the Fluid app used most often and check whether any setting beyond the general ones was changed. If not, rebuild it today with Safari's Add to Dock or Chrome's Install page as app, and leave the rest until that one has run for a week. If it relies on link rules, scripts or a second account, try it in a paid tool's free tier, and the Guide shows how a first app is created step by step.
