Stop launching SimHub manually
SimLauncher starts SimHub automatically with any sim racing game. Create a per-game profile, add SimHub, and it launches in the right order every time - iRacing, Assetto Corsa, ACC, AMS2 and more.

SimHub auto-start - per game, per setup
SimHub has a built-in autostart option, but it only controls when SimHub itself starts with Windows - it doesn't respond to individual sims launching. SimLauncher is different: it starts SimHub in response to a specific profile, in the correct position relative to your other apps, with configurable delays so SimHub is fully initialised before your rig software and overlays start.
SimHub is a Swiss-army knife for sim racers - dashboards, overlays, tactile feedback, motion, bass shaker control. It's one of the first things you want up each session, and manually opening it every time gets old fast.
SimLauncher treats SimHub as a first-class companion app. Add it to any profile, set the launch order and delay, and it starts at the right moment every time - whether you're loading iRacing, Assetto Corsa, ACC, AMS2, or any other sim.
Different sims, different SimHub dashboards? Create separate profiles per sim. Your iRacing setup launches one SimHub config, your AC setup launches another. One click each, zero manual steps.
How to set up SimHub autostart in four steps
-
1
Add SimHub to SimLauncher
Open SimLauncher Settings and go to the Apps tab. Find SimHub in the built-in companion app list and point it to your SimHub executable. SimLauncher remembers the path across all profiles.
-
2
Create a profile for your sim
On the Launcher tab, click the settings icon next to your sim - iRacing, Assetto Corsa, ACC, AMS2, or any other. Enable SimHub in the companion app list for that profile. Repeat for each sim you run.
-
3
Set launch order and delay
Set a delay of 2-5 seconds after the sim so SimHub starts right behind it and connects cleanly - dashboards and overlays are live from lap one.
-
4
Hit Launch - SimHub runs itself from here
Every time you open that profile, your sim launches and SimHub comes up right behind it, in the right order, with the right delay. No manual steps, no forgotten launches, no missing dashboard data mid-session.

Built for complex sim racing rigs
Engineered to manage high-end rigs, VR setups, and motion platforms.
SimLauncher is for you if:
- You run multiple sims (iRacing, AC, ACC, AMS2, etc.)
- You switch between different setups (VR vs triples, motion on/off, etc.)
- You use multiple companion apps (SimHub, CrewChief, overlays, telemetry, wheelbase software...)
- You care about launch order, delays, and reliability
- You want a single click to go from desktop to fully ready rig
Probably not for you if:
- You run one sim and one or two apps
- You're fine with everything starting with Windows
- You don't need different setups
- You don't care about launch order or coordination between apps
Common Questions
How do I make SimHub start automatically with iRacing?
In SimLauncher, open your iRacing profile settings and enable SimHub in the companion app list. Set a delay of 2–5 seconds so SimHub comes up right after iRacing and connects before the first lap - dashboards and overlays are ready when you load in. Once configured, the whole sequence runs automatically every time you open that profile. When you're done, you can close SimHub with one click.
Can I have different SimHub setups for different sims?
Yes. Each profile in SimLauncher is completely independent, so your iRacing profile can have a different SimHub configuration than your Assetto Corsa or ACC profile. Different apps enabled, different launch order, different delays - all stored separately per profile. Switch between sims, switch profiles, and the right SimHub setup loads every time without any manual changes.
When does SimLauncher start SimHub?
SimLauncher launches your sim first, then brings up SimHub and your other companion apps in the order you set, each after a configurable delay. So SimHub comes up right behind the sim and is connected - dashboards and overlays live - by the time you load into a session. You control the order of the companion apps among themselves.
Is SimLauncher free?
Yes, completely free. No subscription, no premium tier, no locked features. SimLauncher is open-source under GPL v3 - the full code is on GitHub. It supports 27 sims, per-game profiles, configurable launch order, custom delays between apps, and one-click kill/relaunch of running apps. SimHub, Crew Chief, and any other tool you use are all supported. Built by a sim racer for the community.
