Typst
A markup-based typesetting system
Details
The project is split up into a FOSS compiler and a closed-source web-app.
The web-app is primarily a Typst editor that uses the compiler internally. It is closed source. The home page primarily advertises the web-app, but also provides a front-page link to the source code.
The compiler is licensed under the Apache 2.0 and can without issue be used on its own.
The compiler includes a package manager “Typst Universe” that may connect to servers owned and operated by Typst GmbH. Use of the package manager does not seem to require the user to accept any Terms of Conditions. Packages published on Typst Universe are required to be offered under the terms of an OSI-approved license, or or a version of CC-BY, CC-BY-SA, or CC0.
Employees of Typst GmbH maintain the compiler and are responsible for most of the development. Typst GmbH is funded through individual subscriptions and enterprise contracts, GitHub sponsorships, and grants, such as by the NLnet Foundation. Based on Discord messages (1, 2) from project members, they state they received private funding in 2023 and are not venture funded as of November 2024.
