fastlane-plugin-app_dropper

Upload the build your lane just produced to App Dropper and get a shareable install link back.

fastlane add_plugin app_dropper

Generate an API token under Settings → API tokens in your App Dropper dashboard, and export it:

export APPDROPPER_TOKEN="adp_…"

Each token is scoped to a single app and carries one scope, upload:builds — it cannot delete builds, manage testers, read billing, or reach another app.

With no arguments, the action uploads whatever the lane most recently built — IPA_OUTPUT_PATH, falling back to GRADLE_APK_OUTPUT_PATH:

lane :beta do
  build_app(scheme: "MyApp", export_method: "ad-hoc")
  app_dropper
end

Or spell it out:

lane :beta do
  build_app(scheme: "MyApp", export_method: "ad-hoc")

  app_dropper(
    api_token: ENV["APPDROPPER_TOKEN"],
    file: lane_context[SharedValues::IPA_OUTPUT_PATH],
    release_notes: last_git_commit[:message],
    tag: "adhoc"
  )
end

lane :beta do
  gradle(task: "assemble", build_type: "Release")

  app_dropper(
    file: lane_context[SharedValues::GRADLE_APK_OUTPUT_PATH],
    release_notes: last_git_commit[:message]
  )
end

api_token is declared sensitive, so fastlane redacts it from logs and from the run summary.

The action returns the install link, and also sets:

url = app_dropper
slack(message: "New iOS beta is up: #{url}")

The action is deliberately shaped like the community diawi plugin, so the change is mechanical:

# Before
diawi(
  token: ENV["DIAWI_TOKEN"],
  file: lane_context[SharedValues::IPA_OUTPUT_PATH],
  comment: last_git_commit[:message]
)

# After
app_dropper(
  api_token: ENV["APPDROPPER_TOKEN"],
  file: lane_context[SharedValues::IPA_OUTPUT_PATH],
  release_notes: last_git_commit[:message]
)

Both block the lane until the build is processed and both return a link. App Dropper additionally groups builds into an app with full version history, notifies your registered testers by email and push, and keeps builds for 7 days on free or 30 on Pro (indefinitely if you pin one).

A successful upload emails and push-notifies everyone on the app with "A new version is available for {your app}" — the account the token belongs to included, since nobody watched the lane run. Running inside CI, the plugin reads the runner's environment (GitHub Actions, GitLab CI, Bitrise, CircleCI, Bitbucket Pipelines, Codemagic, Jenkins and friends) so that email can name the branch and commit and link back to the build. Set APPDROPPER_NO_CI_INFO=1 to leave those details out.

The binary never passes through the API. The action reserves an upload (which is where every plan limit and quota is applied), streams the file straight to Google Cloud Storage, then waits for the server to parse it. That's what keeps a 500 MB .ipa clear of the request-size ceilings every HTTP API has.

No runtime dependencies — everything uses Ruby's standard library, so installing this plugin can't drag a conflicting HTTP gem into your Gemfile.lock.
