A font quality assurance tool for everyone
Decision gist · record as of 2026-08-14
Yes, if you are developing fonts or managing font projects. Font Bakery is a mature tool with no known vulnerabilities and low install friction. The aging maintenance status (316 days since last release) is offset by its long history and continued use by professional foundries. Install it if font quality assurance is part of your workflow.AI-flagged interpretation of the facts on this page — verify before relying

What it is and what it does
Font Bakery is a terminal-based quality assurance tool for font projects. It runs a suite of automated checks against OpenType font files and project metadata (such as Google Fonts METADATA.pb files) to catch quality issues early. The tool was originally built to accelerate onboarding for Google Fonts and has since become a community project with contributors from major foundries and type organizations.
You typically use Font Bakery as a command-line utility in your font development workflow, or integrate it into continuous integration services like GitHub Actions to run checks on each commit. It can also be extended with custom checks written in Python for project-specific validation needs. The package depends on a substantial set of font-handling libraries including fontTools, uharfbuzz, freetype-py, and others to perform its analysis.
Use it for
- Validate OpenType font files for spec compliance and common quality issues before distribution.
- Integrate font checking into GitHub Actions or CI/CD pipelines to catch regressions on each commit.
- Check Google Fonts METADATA.pb project files for correctness and consistency.
- Write custom font validation checks tailored to a foundry's internal quality standards.
- Audit existing font projects for quality issues across multiple files in batch.
