PDF and Office libraries for Go, and open-source tools for Go supply-chain security and ISO 27001. UniDoc ehf. is an Icelandic company and has built these libraries since 2016.

go get github.com/unidoc/unipdf/v5
go get github.com/unidoc/unioffice/v2

UniPDF and UniOffice are pure Go with no cgo: no native libraries, no JVM and no sidecar. Every dependency is an ordinary Go module, listed in go.mod, so you can check them with go mod graph and govulncheck. With an offline licence key they make no network calls.

pkg.go.dev does not show documentation for commercially licensed modules, so the API reference is at apidocs.unidoc.io and guides are at docs.unidoc.io. The examples repositories have runnable code for most tasks: UniPDF, UniOffice, UniHTML. Get a trial key at cloud.unidoc.io.

UniSupply (Apache-2.0) checks a Go module's dependencies for known vulnerabilities and upkeep, and grades the risk from A to F with the reason and the fix. Run it on your own module or in CI.

go install github.com/unidoc/unisupply/cmd/unisupply@latest

ISMS (Apache-2.0) runs an information security management system for ISO 27001 and similar standards. Policies and records live as documents in git, and the whole system ships as one binary. More at isms.sh.

PDF Debugger (Apache-2.0) shows what is inside a PDF file. UniChart (MIT) draws charts in Go. UniType reads TrueType fonts in Go. UniPDF CLI runs common UniPDF operations from the command line.
