Comparison
Different tools for different release workflows.
ascdir is a focused App Store Connect CLI. fastlane is a broad automation ecosystem. They can be alternatives for some tasks or work together.
| Area | ascdir | fastlane |
|---|---|---|
| Primary purpose | Declarative management of selected App Store state | End-to-end mobile release automation |
| Local representation | YAML, Markdown, and managed asset directories | Ruby configuration plus text-based metadata and asset directories |
| Review and approval | Field- and asset-level read-only plans before supported writes | Interactive HTML preview for deliver metadata; behavior varies by action |
| Clearing and deletion | Explicit empty values and destructive changes require operation-specific flags | Replacement and overwrite behavior is configured per action |
| Scope | Metadata, product-page assets, TestFlight distribution, submission, and release | Build, sign, test, upload, deploy, and more |
| Build responsibility | Uses builds uploaded by Xcode, Transporter, or another build pipeline | Build, signing, testing, and upload can run in the same ecosystem |
| Best fit | Teams wanting a compact declaration with field-level plans and explicit guards | Teams wanting a broad mobile automation toolbox |

Choose the tool that matches your workflow.
Use ascdir when a compact App Store declaration, field-level plans, and explicit guards are the priority. Use fastlane when you need build, signing, testing, and deployment in one ecosystem. They can also work together: fastlane can build and upload the binary, then ascdir can manage metadata, TestFlight distribution, submission, and release.
