It offers a command-line interface and Ruby API for workflows such as automated publishing, PDF generation, design automation, containerized environments, visual testing, and CI/CD. Its searchable registry lists 2,534 font families and 4,286 formulas, with filters for license and source. YAML manifests let users specify font requirements for repeatable installations across machines and pipelines. Fontist can be used with GitHub Actions, GitLab CI, Jenkins, and other runners, and optional fontconfig integration supports font discovery on Linux. It can detect and index fonts already installed on a system. Fonts can be placed in managed storage, user directories, or system-wide directories; the last option requires administrator permissions. Formulas include download instructions, checksums, and metadata, and the software describes license handling during installation. Supported formats include TTF, OTF, TTC, OTC, dfont, WOFF, WOFF2, PFB, and PFA. It is open-source software with a free plan at free.
