Holtdroid
The portal
holtdroid
The api and web UI, the device providers, the agent that runs next to every device, the SSH gateway, the holtdroid client for your computer and the Helm chart.

Android test devices,
right in your browser
Holtdroid launches Android on your Kubernetes for any APK from Slack, S3 or GitHub, and hands you the screen, Chrome DevTools for its WebViews, clipboard and a VPN of its own, in one tab.
Features
Everything a tester needs, nothing to install
Each device is yours alone, starts clean and goes back to the pool when you are done.
Chrome DevTools for every WebView
Remote debugging is switched on at runtime. The APK stays exactly as your team shipped it.
A country per device
Switch the exit location mid-session, next to the screen.
Sessions that clean up
Bounded slots, an idle timeout and a max TTL.
ARM apps on x86 nodes
Android runs in containers, several per node, with ARM translation.
Real phones over USB
No root, no Wi-Fi: the phone's traffic goes over the cable.
Record a bug, share one link
Video, logcat, network and console on one timeline, with markers where things went wrong.
See every lookup and connection
The DNS log and the routes behind each name: far servers, missing names, connections that aren't reused. Point a name at staging without a rebuild.
Heavy images and SVG icons
What a screen downloads for nothing, too big or in an old format, and icons with extra digits.
Pluggable by contract
Swap sources, devices, VPN, secrets and sign-in. No vendor lock-in.
Open source
From a Slack message to a device in your tab
Six repositories, each doing one job. Use them together, or take only the piece you need.
Builds come in
Sync jobs copy APKs from Slack, S3 and GitHub releases.
The portal
Lists apps, hands out slots, proxies screen and DevTools.
Devices
Android in containers, or real phones on USB.
Your browser
Screen, DevTools, files, logcat and recordings.
Android images
holtdroid-redroid
redroid, Android in a container, prepared for sessions: one image per Android version, with ARM64 translation for ARM-only builds.
Where builds come from
holtdroid-sync
Jobs that copy APKs from Slack channels, S3 buckets and GitHub releases into Holtdroid's sources, with icons and changelogs.
Network for real phones
holtdroid-tunnel
A VpnService that sends all of a phone's traffic over USB to the host, so a USB phone gets the session's country without root or Wi-Fi.
Test browser
holtdroid-webview
An Android WebView playground with DevTools unlocked, presets of WebView settings and adb control. Works without Holtdroid too.
Browser versions on demand
chromium-builds
Chromium and WebView for Android built from release tags with proprietary codecs, to reproduce a bug on the exact version it was reported on.
Get started
Give your testers a cozy holt
Try the whole UI on your laptop with simulated devices, then install one Helm chart on your cluster.
# simulated devices on :8080 $ git clone https://github.com/holtdroid/holtdroid $ cd holtdroid && mise install $ make dev
# values.yaml: see Installation $ helm install holtdroid \ oci://ghcr.io/holtdroid/charts/holtdroid \ -n holtdroid -f values.yaml
