Who hunted tapflow?
tapflow was hunted by Duchan. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.

Duchan
Our QA team needed a way to run iOS and Android testing in the browser — without setting up Xcode on every machine.
I looked at Appetize and BrowserStack. Both solved the problem, but before signing up I hit two issues:
The pricing scales fast with team size ($59+/month and up)
App binaries get uploaded to their cloud — a non-starter for anything sensitive
We already had Macs in the office. Why pay monthly for cloud simulators we could run ourselves?
So I built tapflow instead.
tapflow lets teams run iOS simulators and Android emulators directly in the browser using Macs they already own.
No cloud uploads.
No monthly device farm fees.
No app binaries leaving your network.
Getting started is simple:
After that, your QA team can open a browser and start testing immediately.
Tap, swipe, install builds, rotate devices, take screenshots — all from the browser.
What's included:
Browser-based simulator & emulator control
iOS + Android support
Team management with invites and roles
Build uploads from the dashboard
Fully self-hosted
MIT licensed
One technical detail I'm especially proud of:
iOS simulator touch works without WebDriverAgent using SimDeviceLegacyHIDClient + IndigoHID.
We've been using it internally for a while, and I finally cleaned it up enough to open source it.
It's still early (v0.2.1), so there are definitely rough edges, but the core workflow is already usable.
Would genuinely love feedback from mobile teams, QA engineers, or anyone building internal developer tools.
And if it looks useful, a ⭐ on GitHub would really help the project get discovered.
