Holtdroid is a self-hosted, browser-based Android sandbox for testing APKs. Pick a build that your CI or a sync job dropped into a folder or S3 bucket, launch an Android device on demand, and get the device screen, Chrome DevTools for the app's WebViews, clipboard sync and a VPN location switcher in one browser tab. It runs on Kubernetes, is infrastructure-agnostic and Apache-2.0.
