LaTeX Compilation
TeXlyre uses TeXlyre-BusyTeX to run TeX Live 2026 directly in the browser. Documents are compiled locally; TeX Live files that are not bundled can be fetched from the configured package server when needed.
Bibliographies
TeXlyre supports both traditional BibTeX workflows and BibLaTeX with Biber. Bibliography processing runs in the browser as part of the compilation pipeline.
Fonts
TeXlyre can use fonts from the TeX Live distribution without bundling the full font collection in the browser. When a TeX Live font is not available locally, BusyTeX resolves it through prebuilt font metadata and fetches the required font file from the TeX Live server.
Accessibility
LaTeX gained a tagging pipeline in recent releases, driven by the \DocumentMetadata interface. TeX Live 2026 includes it, so TeXlyre can produce structurally tagged PDFs in the browser without a local TeX installation.
