SimLauncher: One click. Everything running.
SimLauncher starts your sim, companion apps, overlays, telemetry tools, and rig software from one profile.

What is SimLauncher?
SimLauncher is a free, open-source Windows app - a dedicated sim racing startup manager - that launches your whole sim racing setup in one click. Instead of manually opening SimHub, Crew Chief, your overlays, your rig software, and the sim itself before every session, SimLauncher starts the entire stack for you - the sim first, then each companion app in the order you set, with a configurable delay before each one so everything has time to initialize.
A serious rig isn't one app, it's five, six, or seven. SimHub for dashboards and tactile feedback, Crew Chief for spotter and strategy calls, MOZA Pit House or Fanatec Fanalab for your wheelbase, maybe a bass-shaker controller or a VR runtime - and then the sim itself. Starting all of that by hand before each session wastes time and invites mistakes: the overlay you forgot, the app you launched in the wrong order. SimLauncher removes that friction so you go from desktop to fully running rig with one click.
How does it compare to the usual workarounds? Windows Task Scheduler can start apps on login but can't tie a launch to a specific sim or sequence companion apps. Batch scripts can chain launches but can't insert reliable, configurable delays between them. SimHub can launch some companion tools from within itself, but it can't start SimHub automatically when a sim launches - you still have to open SimHub first. Single-purpose Crew Chief launchers only handle Crew Chief. SimLauncher does the whole stack from one profile: the sim first, then every companion app you use, in your order, with per-step delays.
SimLauncher is built to be trusted. The full source is public under the GPL v3 license, so you can read every line, the commit history, and the CI runs on GitHub before you install anything - or build it yourself from source instead of running the published installer. Releases are built in CI from tagged commits, with each release linking the issues and pull requests behind every change. No account, no subscription, no telemetry - your configuration stays entirely on your machine. Built by a sim racer, for sim racers, and it stays free.

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 start SimHub and Crew Chief with iRacing automatically?
Create an iRacing profile in SimLauncher, add SimHub and Crew Chief to the companion app list, and set the launch order and delays. Once that's done, opening the profile starts everything in sequence automatically - iRacing first, then SimHub and Crew Chief right behind it, with a short delay before each so they connect cleanly. When you're done, one click closes the companion apps from the running-apps strip. The whole setup takes about five minutes and works the same way for every sim SimLauncher supports.
Can I use SimLauncher for different setups like VR or Motion?
Yes. SimLauncher lets you create multiple profiles for the same sim. So you can have an 'iRacing VR' profile that starts your VR runtime and motion software, and a separate 'iRacing Triples' profile with a different app stack. Each profile has its own companion app list, launch order, and delay settings, completely independent from each other. Switch between them with one click - no manual adjustments needed when you change rigs.
Is it compatible with Assetto Corsa and Content Manager?
Yes. SimLauncher supports Assetto Corsa, ACC, and 21+ other sims. For Assetto Corsa, you can point the profile at Content Manager or LFM instead of the default executable - SimLauncher just launches whatever path you give it. Your companion apps (SimHub, Crew Chief, overlays) still start in sequence right after the game, in your configured order, regardless of which launcher you use to start AC.
Is SimLauncher really free?
Yes, completely free. No subscriptions, no premium tier, no locked features. SimLauncher is open-source under GPL v3 - the full code is on GitHub if you want to check what it does before installing. It covers everything: per-game profiles, configurable launch order, custom delays, one-click kill/relaunch of running apps, support for 21+ sims and tools like SimHub and Crew Chief. Built by a sim racer for the community, and it's staying free.
How do I install SimLauncher, and what does it need to run?
Download the latest installer from the GitHub releases page and run it - the setup wizard handles the rest, then you set your game and app paths in Settings. SimLauncher runs on Windows 10 and Windows 11 (64-bit), and everything it needs is bundled in the installer, so there's no separate runtime or framework to install. On first launch, Windows SmartScreen may warn because the installer isn't code-signed yet - click More info, then Run anyway.
Does SimLauncher collect any data?
No. SimLauncher collects no telemetry or analytics, has no accounts, and keeps your profiles and settings on your PC. The only network requests it makes are to GitHub, to check for and download app updates. The full source is public under GPL v3, so you can verify exactly what it does.
