FontSiphon vs RightFont: What $59 Buys, and What It Doesn't

RightFont costs $59.00 for a single licence, putting the app on one device with one year of updates and a 30-day money back guarantee. This post was checked against their own pricing, licence and documentation pages on 13 September 2026.

You either buy a standalone product, or you use a desktop app like FontSiphon from the getapps.cafe Mocha menu. One membership includes every app, licensed per device.

Where RightFont wins outright

RightFont integrates directly with design applications like Photoshop, Illustrator, Sketch, InDesign and Affinity Designer. These are direct connections, not extra plugins. When you open a document containing missing fonts, RightFont automatically activates the required fonts from your libraries so you can continue working without interruption. Silent Mode handles this entirely in the background. No dialog.

You can switch the typeface of a selected text layer with one click. Select the text, move the cursor over a font in the RightFont window, and click the Apply Font button beside it. They claim the app helps you stay fast and organized, even with tens of thousands of fonts. You can also share those libraries across a team. Just save them into a shared folder managed by a cloud storage service like Dropbox, Google Drive, or Box.

RightFont also supports syncing the Google Fonts collection to your desktop. It syncs variable fonts by default. This is a genuine advantage over FontSiphon, which only writes static weights when it installs from the Google catalogue.

Windows is not an afterthought

FontSiphon runs on Windows as well as macOS, with both x64 and arm64 builds sitting at version 1.7.1 today. The Windows half is a real build. Its source carries a Windows-only module that writes the font into the registry and broadcasts a font-change message, because Windows reads its font table from the registry rather than from the folder. On Windows it installs into the per-user font folder, which needs no administrator rights.

That broadcast is sent with a one-second timeout. One hung window cannot wedge a toggle. Without it, an already open Word or Photoshop keeps showing the old list until it restarts. RightFont is made exclusively for the Mac, and requires macOS 11 or newer. Their download page offers a Mac build only. There is no Windows version.

The offline Google catalogue

FontSiphon carries the whole Google Fonts catalogue as a trimmed snapshot compiled into the app. On a fresh install, 1,946 families browse and preview offline before anything is fetched. That count was exact on 12 September 2026, and refreshing the app replaces the snapshot with a live copy from Google. The list pages 60 rows at a time as you scroll, and families you have already installed lead it whatever sort you pick. Installing a family writes real .ttf files into your own font folder, like ~/Library/Fonts on a Mac, which is the folder the operating system reads. Every application on the machine sees the font. There is no second activate step.

It asks for every script the family carries, not just Latin. Every request is for the whole family. The default Latin subset returns a valid, installable font missing the script you picked the family for. Open Sans arrives at 35 KB with 51 of the 67 Vietnamese letters absent, and Noto Sans JP arrives as 34 KB of Latin instead of 5.3 MB. Nothing errors when that happens; the specimen just renders in a fallback. Downloaded files are named the way a designer would name them, like Inter-BoldItalic.ttf. A truncated download is rejected rather than written. It works offline apart from the Google Fonts library, which is the only thing it goes online for.

What actually stays behind

Switching a family off in FontSiphon moves its file out of your font folder and into FontSiphon's own vault, a documented folder in the app's data directory. Switching it on moves it back. The file's location is the state, which is why the change shows up everywhere at once and survives a restart. A deactivated font still shows a real specimen, because the app reads the file's own bytes rather than asking the system. You get live specimens in every row, your own preview text, a size slider from 10 to 120 pixels, and list, grid or waterfall layouts.

Nothing is deleted. If another file has taken the original name while the font was parked, the returning file is placed beside it rather than over it. Deleting a font file is a separate action that asks for confirmation. Uninstall refuses to touch a font it did not install. It reads its own record of installs and errors with "FontSiphon did not install that family" otherwise.

Buying a device seat

RightFont sets a straightforward price of $59.00 for one device. That one-time purchase includes a year of updates and support. When those twelve months run out, you can upgrade your license with a 50% discount. A volume licence lists at $250.75, marked down from $295.00, though the page skips mentioning how many seats that buys. Students and educational institutions get a 30% discount, and anyone can take a 15-day free trial without registering. The software requires macOS 11 or newer, and there is no Windows build. You buy a licence for each of your devices. It can move to a new machine. It just has to be deactivated on the old one first.

A getapps.cafe membership approaches a desk differently. You buy one plan, and that plan includes every app on the menu. The apps are licensed per device, and they are not sold on their own. FontSiphon runs natively on macOS and Windows. If you use a mixed desk, one membership spans both sides of it. The choice rests entirely on how many computers you sit in front of and how much of the menu you actually use.

A family that does not exist

RightFont connects to the design applications designers work in. FontSiphon works with DocCafe, SheetCafe and SlideCafe. Both are real integrations serving different people. This isn't an Adobe-style plugin. Nothing detects a missing font in a document and switches it on, and nothing applies a font to selected text from the font manager window. RightFont documents both of those, with no equivalent. All three have a Font Manager row in Settings with an Open FontSiphon button. On a Mac it asks the operating system for the app, opening the web page if missing. The launching half is compiled for macOS only, so on Windows the button always opens the web page and never launches the app.

When a font lands in ~/Library/Fonts, WebKit hides it from the web content process. Its name reaches the picker, but drawing it silently renders a fallback. On macOS 26, Helvetica and Georgia draw. Pacifico, Quicksand and Dancing Script measure exactly as wide as a family that does not exist. The native process enumerates your families, and the picker asks for that list every time it opens. A font activated while running turns up straight away. The app hands the page the actual files, and the page registers them itself via the CSS Font Loading API. It costs no reload, which would throw away an unsaved workbook.

On Windows, a font installed while open renders a fallback face until the webview reloads, because the font collection goes stale per document. DocCafe floats new families to the top instead of burying them alphabetically. It works whatever installed the file: FontSiphon, Font Book, or a .ttf double-click.

Where the app stops

FontSiphon draws hard boundaries. The system font folder is locked by the operating system, so the app cannot touch it at all. The shared font folder needs administrator rights, which FontSiphon does not ask for. It shows a plain explanation rather than a toggle that would fail. A .ttc file moves as a unit in both directions. Switching one face on or off switches the other faces in the same file the same way, and the app says so.

Other limits come from the format. A variable family downloads as static weights, dropping one file per weight instead of the variable font. The application reads the variable axes perfectly well, but what lands on your disk is static instances. Classification relies on a font's own descriptor. The fallback is a name heuristic. If a file describes itself wrongly, the list reflects that. Trattatello calls itself a rounded sans. Downloading a Google font needs the network. Browsing all 1,946 families does not, because the catalogue ships inside the software.

RightFont belongs on a different kind of desk. Buy it if you live inside Adobe apps, Figma, Sketch, Affinity or QuarkXPress all day and want your font manager wired directly into them. It handles client files that demand inactive fonts exactly when the document opens, and changes the typeface of selected text in one click. It serves a team sharing a single library. It is built for a Mac, only a Mac, holding a very large catalogue.

You are choosing the tool that fits your desk. One wires itself into your design applications on a Mac. The other runs on both kinds of machine, treating a switched-off font as a visible file move. You can browse the rest of the menu and start a free trial at getapps.cafe/membership.
