- HTML is the documented output format
- Blog support is optional rather than central to the tool

Our verdict on Scaladoc

Scaladoc is an open-source documentation generator for Scala library and application developers. It creates HTML API documentation from Scala source-code comments, with output tied to the structure of the code. Source inputs include Scala source code, TASTy files, and JAR files. Teams can run it through sbt or its command-line utility, making it suited to projects that already organize builds and documentation around the Scala toolchain.

Its strongest fit is a Scala-centered documentation workflow that needs more than a basic API reference. Scala 3’s implementation supports Markdown and legacy Wiki syntax, static documentation sites, versioned documentation, and type-based search. Optional snippet compilation and checking can help connect documented examples with compilable code, while built-in blog support extends the tool toward project documentation. These capabilities make Scaladoc relevant for maintainers publishing multiple documentation versions alongside evolving Scala libraries or applications.

Scaladoc is distributed as part of the Scala toolchain, not as a hosted commercial service with paid tiers. That keeps its scope focused on generating and publishing documentation rather than providing a broader documentation workspace. Teams looking for Scala HTML output, sbt integration, command-line workflows, versioned sites, and type-oriented navigation should consider it a strong match. It is less suitable for organizations seeking a multi-language documentation platform, a hosted authoring environment, or output formats beyond HTML.
