GameMaker will make its GMRT runtime free for all developers from January 1, 2027, removing the paid licence that previously gated shipping a commercial game on the engine.
What changed: GameMaker is making GMRT free to use for commercial projects starting January 1, 2027. Why it matters: Shipping cost is a real barrier for small teams, and this removes it on PC, mobile, browser and GX Games. Who should care: Solo developers and small studios already using GameMaker, and anyone who ruled the engine out on licensing cost.
The licensing change
| Item | Before | From January 1, 2027 |
|---|---|---|
| Shipping on GMRT | Professional licence required | Free |
| Shipping on GMS2 | Professional licence required | Unchanged by this announcement |
| Platforms covered | — | PC, mobile, browser, GX Games |
| Owner | Opera | Opera |
The distinction between GMRT and GMS2 matters. GMRT is the newer runtime, announced in April 2026, and the free tier applies to it — not automatically to the older GMS2 runtime. Developers still shipping on GMS2 should check which runtime their project targets before assuming the change applies.
Why GMRT is the interesting one
GMRT arrived with tooling aimed at modern workflows, including support for AI-assisted programming on Claude Code. That combination — a 2D engine with an AI-oriented toolchain, now free to ship on — is a different proposition from the GameMaker that small teams evaluated two years ago.
GameMaker’s audience has always been the solo developer and the small studio, and licensing has been the line between “prototype in it” and “ship in it”. Removing that line on the newer runtime is a bet that more shipped games produce more long-term value than licence revenue does.
What it does not change
A free runtime does not remove platform fees. Console publishing still carries the platform holder’s requirements, and GameMaker’s console support is a separate arrangement from the runtime licence. The announcement covers PC, mobile, browser and GX Games specifically.
There is also no statement about whether existing professional licence holders receive anything in return, or whether the change affects support tiers.
The competitive read
Engine choice for 2D projects has been consolidating around free-to-ship options for years. A free runtime puts GameMaker back into consideration for teams that had moved to alternatives purely on cost, and it lowers the risk of starting a project in the engine before knowing whether it will ship.
Forward look
The change takes effect on January 1, 2027. Before then, the practical question for existing projects is whether they target GMRT or GMS2 — and for anyone planning a 2027 release, whether the runtime switch is worth making while the licence is still required.
