Blume 2.0

Blume 2.0 is an open-source documentation site generator that migrates sites from version 1 to 2 and configures adapters.

Blume 2.0 updates configuration structures for documentation sites without requiring content edits to Markdown and MDX pages. It provides a command-line upgrade tool that checks project settings, bumps versions, and reports file replacements. Settings for search, deployment, content sources, API references, analytics, and assistant model backends become adapters imported from subpaths. The tool also integrates with coding agents like Codex and Claude Code to apply changes interactively. The software runs locally and is free under an MIT license.
