While proofs are an essential part of the design and production process for every professional font, making them is often time consuming, error prone, or dependent on custom Python scripts. Font Proofer removes this friction so you can spend more time on what matters:
Font Proofer has become my standard for making proofs.
Wrangling InDesign files can waste numerous hours every week, especially when I’m right in the middle of working on a font. Switching to a couple of clicks is massively more productive.
Update your proof with one click as you make changes
to your design in Glyphs 3 or RoboFont 4.
Font Proofer integrates directly into my design workflow because it’s easily accessible from the font editor. Now I can concentrate on type design itself.
Never waste another minute deleting characters that aren’t in your font yet. Whether in a spacing string or a paragraph, blank gaps and fallback glyphs reduce the efficacy of your proof. Font Proofer intelligently removes them for you.

Sample text in a font missing x, w, and exclamation mark glyphs, and with a blank (yet to be designed) asterisk glyph.
I couldn’t live without this, especially in the early stages of a design.

Made with Font Proofer
Your proof always uses the latest version of your design. You can finally forget about font caching, find-and-replace fonts, and managing files for every small iteration.
Save documents as .proof files to share with your colleagues and students. Easily copy and paste sections between proofs, and reuse them for any font.
Built with the latest technologies, Font Proofer is fast, stable, and familiar. It supports dark mode, native file saving, and all of the other Mac features you rely on.
There’s an exciting roadmap of features planned, including:

Designers have already used Font Proofer with a variety of scripts—including Latin, Cyrillic, Arabic, Devanagari, Thai, and Chinese. It supports OpenType localized forms and bi-directional text, and vertical typesetting is on the roadmap. I’m committed to making this a tool for many languages and writing systems, and welcome feedback about your proofing needs.
Every type designer and foundry should use Font Proofer. Seriously. Just using it to proof family structure, spacing, kerning, features, and style comparison yields consistent, well-designed typefaces in less time. Plus, it’s fun to use!

Peter Nowell is a multidisciplinary designer, teacher, and inventor based in New York. His design portfolio spans UI/UX, web development, branding, print, and custom typography for clients as small as San Francisco’s Juice Shop and as large as Apple.
While studying typeface design in Type@Cooper, Peter realized how vital proofing is to the development of every professional font—but also how tedious it can be to create, edit, and reuse proof documents. Determined to find a better way, he taught himself new programming languages and applied his experience in UI/UX, graphic design, and teaching to develop a tool for the type design community. Three years later, he launched Font Proofer!
Peter has self-funded Font Proofer’s development, driven by the overwhelming enthusiasm from fellow type designers for a tool like this—the first of its kind. Peter’s goal is for Font Proofer to become a sustainable, community-supported project helping both experts and beginners to design their best type.
It’s rare to see someone pour so much care and attention-to-detail into a new app for type design. Font Proofer dramatically improves a crucial aspect of type creation — proofing — which is cumbersome and error-prone in traditional software. I love this tool already and can’t wait to see how it evolves!
