Bring your freeware to SimAtlas
Your add-ons stay free for every SimAtlas user, with no subscription and no credit card. They appear alongside payware in the catalog, so simmers who'd never dig through forums can find them.
What you get
Updates reach everyone
Publish an update once and every user gets it automatically. Only changed files are downloaded, and no one is left on an old version.
Dependencies installed for your users
Link the libraries your add-on needs. When a dependency is available on SimAtlas, it's installed automatically alongside your add-on.
No client running
Once installed, free add-ons work in MSFS without the SimAtlas client open, just like a manual install.
Seen next to payware
Your add-ons show up on the map, in recently added, on the country pages and on your own developer page.
Usage statistics
See how many simmers use your add-ons in the developer portal, the same statistics payware partners get.
A donate button
Users can support your work through a donate button shown with your add-ons in the SimAtlas app.
Nothing to host
We handle hosting and delivery. No file hosts, download limits or Community folder support threads.
Room to grow
If you later build payware, you're already set up to license it to SimAtlas+ through our partner program.
Not every library can be redistributed through SimAtlas. If your add-on relies on one we can't include, your users install that one themselves, as they do today. Ask us which of yours are covered.
How listing your freeware works
- Get in touch and tell us about your add-ons and the libraries they need
- We take a look: quality, your right to distribute the add-on, and which dependencies are covered
- We do the first upload for you and set up your developer page
- You get access to the developer portal to publish updates and see your usage statistics
Freeware FAQ
Do my users need a subscription?
No. Free add-ons are open to every SimAtlas account, with no subscription and no credit card.
Do my users need the SimAtlas client running?
No. The client is only needed to install and update free add-ons. In MSFS they work without it.
What about the libraries my add-on depends on?
Link them to your add-on, and the ones available on SimAtlas are installed for your users. Tell us which libraries you use and we will check which are covered.
Who uploads my add-on?
We do the first upload. After that, you publish updates yourself in the developer portal.
Can my users support me?
Yes, through the donate button shown with your add-ons in the SimAtlas app.
Can I remove my add-on later?
Yes. Either side can remove an add-on from SimAtlas at any time.
What if I also make payware?
Payware can be licensed to SimAtlas+ for a share of subscription revenue. See the partner program.
