name: OpenBao packages and client libraries
note: >-
  OpenBao ships ONE official client library - the Go client, versioned as a submodule of the main
  repository. Its own docs say so explicitly and add that OpenBao intends to remain API-compatible
  with HashiCorp Vault, so existing Vault client libraries in other languages are expected to work;
  those are third-party and are not counted as OpenBao SDKs here. The rest of the distribution
  surface is the server itself - Homebrew, FreeBSD pkg, Arch, EPEL/Fedora, Debian/Ubuntu/Amazon
  Linux repos at pkgs.openbao.org, and container images on ghcr.io, quay.io and docker.io.
packages:
- name: github.com/openbao/openbao/api/v2
  registry: go
  official: true
  language: Go
  kind: sdk
  url: https://pkg.go.dev/github.com/openbao/openbao/api/v2
  install: go get github.com/openbao/openbao/api/v2
  version: v2.6.0
  published: '2026-06-22'
  source: https://proxy.golang.org/github.com/openbao/openbao/api/v2/@latest
  note: The only client library OpenBao lists as officially maintained. Tagged as api/v2.6.0 in the openbao/openbao repository.
- name: github.com/openbao/openbao/sdk/v2
  registry: go
  official: true
  language: Go
  kind: plugin-sdk
  url: https://pkg.go.dev/github.com/openbao/openbao/sdk/v2
  install: go get github.com/openbao/openbao/sdk/v2
  version: v2.6.2
  published: '2026-07-22'
  source: https://proxy.golang.org/github.com/openbao/openbao/sdk/v2/@latest
  note: Plugin-authoring SDK (secrets engines, auth methods, database plugins), not an API client.
- name: github.com/openbao/go-kms-wrapping
  registry: go
  official: true
  language: Go
  kind: library
  url: https://github.com/openbao/go-kms-wrapping
  version: null
  published: null
  note: External KMS interfaces and providers for OpenBao auto-unseal. Version not read - the module is published as several versioned submodules rather than one root module, so a single @latest is not meaningful.
- name: openbao
  registry: homebrew
  official: true
  language: null
  kind: server-cli
  url: https://formulae.brew.sh/formula/openbao
  install: brew install openbao
  version: 2.6.2
  published: '2026-08-18'
  source: https://formulae.brew.sh/api/formula/openbao.json
  note: >-
    Formula stable version read from the Homebrew API. The published date is the date of the matching
    OpenBao v2.6.2 upstream release rather than a Homebrew-published timestamp - the formula API does
    not expose a release date field.
- name: ghcr.io/openbao/openbao
  registry: cdn
  official: true
  kind: container
  url: https://github.com/openbao/openbao/pkgs/container/openbao
  version: 2.6.2
  published: '2026-08-18'
  note: >-
    Alpine-based container image. Also published to quay.io/openbao/openbao and
    docker.io/openbao/openbao, with RHEL UBI variants under openbao-ubi and a distroless variant
    under openbao-distroless (added in v2.6.0). Version tracks the upstream release; the tag `latest`
    floats, so a consumer pinning `latest` cannot tell which build they are getting.
- name: openbao (EPEL / Fedora / Arch / FreeBSD / Debian)
  registry: os-package
  official: true
  kind: server-cli
  url: https://pkgs.openbao.org/
  install: dnf install -y openbao  |  pacman -Sy openbao  |  pkg install openbao
  version: null
  published: null
  note: >-
    OpenBao runs its own package repositories at pkgs.openbao.org for Amazon Linux, Debian, Fedora,
    RHEL and Ubuntu, and is additionally packaged in Arch Linux and EPEL. Version not recorded - these
    are per-distribution repositories with no single unauthenticated metadata endpoint to read a
    canonical latest from.
- name: VaultCourier
  registry: swiftpm
  official: false
  language: Swift
  kind: sdk
  url: https://openbao.org/docs/api/libraries/
  version: null
  published: null
  note: Listed by OpenBao under "Community" client libraries, explicitly not maintained by the project. Not counted as an official SDK.
