A self-hosted platform for running iOS simulators and Android emulators directly in the browser. Uses the Mac your team already owns — no cloud uploads, no monthly fees. MIT open source.
Anyone on our team who needed to check something on mobile — a server developer verifying a sandbox build, a designer checking layouts across screen sizes, a product manager comparing versions — had to stop a mobile developer and ask.
Simulators only ran on developer machines, behind complex toolchain setups. We couldn't ask every team member to go through that just to run a simulator.
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 anyone on your team 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, anyone on your 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.

This is a solid move for teams that want full control over mobile testing without relying on expensive device farms. Keeping everything self hosted also makes compliance and security a lot easier to manage.
@thamibenjelloun Thanks Thami! That's exactly the motivation behind it — teams already have Macs, so why pay for an external farm just to run a simulator? The compliance angle is something we hear a lot too, especially from teams that can't let app data leave the network. Appreciate you checking it out!
