DOCUDEX

Exactly your dependencies, and nothing else.

1. 01 Version-exact

   Docs for the precise module@version in your go.mod — not whatever pkg.go.dev happens to show today. Pin extra versions to compare a release against an upgrade target.

2. 02 Scoped to your project

   Search returns your own dependency surface and the Go standard library — no results from packages you never imported, no noise.

3. 03 Terminal or browser

   docudex search for a quick answer in the terminal, docudex serve for a local web UI — both backed by the same SQLite FTS5 index with BM25 ranking.

4. 04 Fully offline

   Fetching needs the network once. After that every docset in your store is browsable and searchable with no connection — on a plane, in a locked-down environment, or when the docs site is down.

5. 05 Never scrapes

   Docs are extracted from real module source over the Go module proxy protocol and rendered locally with go/doc. They don't rot when a documentation website gets redesigned.

6. 06 Team-friendly

   The committed docudex.toml is the source of truth for doc scope. A teammate gets identical docs from a fresh clone with one docudex sync.

7. 07 Single binary

   One download or one go install. Pure Go, CGO-free, with the web UI embedded — nothing to configure at runtime, no database to run.

8. 08 Greppable Markdown

   Canonical docs are plain Markdown in a content-addressed store — greppable today, and ready for coding agents to consume with no integration tomorrow.

Free and open source. One dependency-free binary — no account, no service. Point docudex at a Go repo and it reads your go.mod, fetches the exact versions you use, and indexes them locally.

1. 01
   Install the binary

   Linux and macOS.

   $ curl -fsSL https://raw.githubusercontent.com/aureliushq/docudex/main/install.sh | sh Copy

   Or run go install github.com/aureliushq/docudex@latest, or download a prebuilt binary for your platform from the releases page.

2. 02
   Initialize the manifest

   Run docudex init in your repo. It reads go.mod, writes a docudex.toml pinning your direct dependencies (plus the Go standard library) to exact versions, and fetches their docs into the store. Commit the manifest so teammates get identical scope with one docudex sync.

   $ docudex init
   OK read      go.mod     38 direct deps + std
   OK fetched   -> ~/.docudex/store
   OK wrote     docudex.toml
   
   # docudex.toml — commit it
   [[docset]]
   module  = "github.com/spf13/cobra"
   version = "v1.8.1"
   
   [[docset]]
   module  = "github.com/charmbracelet/fang"
   version = "v0.2.0"

3. 03
   Search from the terminal

   docudex search <query> runs full-text search over only your project's docsets, ranked by relevance with highlighted snippets and the owning package and symbol.

   $ docudex search "context.WithTimeout"
   
   context · WithTimeout(parent Context, timeout Duration) (Context, CancelFunc)
     Returns a copy of the parent context with the deadline adjusted …
   
   net/http · Server.Shutdown(ctx Context) error
     Gracefully shuts down the server without interrupting connections …
   
   2 results across 38 docsets · 6ms

4. 04
   Browse in the local web UI

   docudex serve starts a local web UI backed by the same index — browse docsets by module, package, and symbol. docudex list shows everything in scope and its fetch state.

   $ docudex serve
   OK index     ready · scoped to this project
   serving docs on http://localhost:8080
   
   $ docudex list
     MODULE                          VERSION   FETCHED
     github.com/spf13/cobra          v1.8.1    OK
     github.com/charmbracelet/fang   v0.2.0    OK
     std                             go1.26    OK
