GameMaker is dropping the paywall for its next-generation runtime. Starting January 1, 2027, developers will be able to build and sell games on the GMRT runtime for free across desktop, mobile, web, and GX Games, according to the announcement published by the Opera-owned engine maker on October 23.
The change removes the Professional license requirement for commercial distribution on new GMRT projects. GameMaker framed it as a move toward making indie development easier to enter, promising developers “more flexibility in how they work with GameMaker and a simplified commercial model for their new projects.”
GameMaker is widely used for 2D indie games. The engine, owned by Opera, has long positioned itself as the accessible on-ramp for solo developers and small teams, and its commercial licensing has been the main friction point between hobby projects and shipped games.
What becomes free
Under the new model, a developer can build a game on GMRT and release it for sale without buying a Professional license first. The free path covers four targets: desktop, mobile, web, and GX Games, the browser-based games platform tied to the same Opera ecosystem.
A web or GX Games build reaches players through a browser link with no store page or approval step, which makes those two targets the cheapest places to ship. Mobile gains the most from dropping the license fee, since a hobby project that would otherwise stay off phones can now publish there, and desktop keeps shipping the way it always has.
Source access now spans every tier, which GameMaker says lets the community “explore GameMaker’s technology, tailor it to their specific project needs, and even potentially contribute to it.” That follows the direction the engine took earlier this year, when it first opened GMRT source access to developers. A team can now read the runtime code behind a bug, adapt the engine to a project’s needs, and send fixes back upstream instead of waiting for the vendor.
Source access also matters for how long a shipped game stays playable. A game built on a closed runtime depends on the vendor’s support window, but a team with the GMRT source can keep a released game running even if official patches stop.
GMRT is GameMaker’s next-generation runtime, the successor to the current GameMaker Studio 2 (GMS2) runtime. It has been rolling out in beta across platforms through 2026, so the licensing change lands while GMRT is still in beta. The tier structure stays in place, but what each tier unlocks shifts: the free tier now includes commercial GMRT releases and source access, the Professional tier becomes the home for legacy GMS2 distribution, and the Enterprise tier keeps console export as its exclusive territory.
What still costs money
The free tier applies to GMRT, not to the older GMS2 runtime. Developers who want to keep selling games built on GMS2 still need a Professional license, though those license holders gain GMS2 runtime source access as part of the change.
Second, consoles are untouched. On either runtime, exporting to a console still requires an Enterprise license and approved-developer status. GameMaker also confirmed that existing tier pricing will not change.
Console approval comes from the platform holders. A developer needs Sony, Microsoft, or Nintendo to accept them as a licensed developer before any engine license matters.
What it means for new developers
For a solo developer starting a new project after January, a GMRT build can go from prototype to a paid release on desktop, mobile, or the web without a Professional license.
Free only applies to GMRT, which is still in beta. A project already built on GMS2 does not automatically unlock; the developer either migrates to GMRT or keeps paying for Professional. Teams that want the licensing advantage now are also signing up to work on a runtime that is not yet feature-complete everywhere.
An existing GMS2 developer’s current project stays on the paid Professional track, and the GMS2 runtime source access those license holders now receive lets them keep shipping a legacy game while deciding whether to rebuild the next one on GMRT.
A competitive repositioning
GameMaker operates in an indie-engine market that is already crowded with free options: Godot is open source at no cost, and Unity’s pricing controversies in recent years sent smaller teams shopping for alternatives. Making the next-generation runtime free for commercial use gives GameMaker a clean “no upfront cost” answer for new projects while keeping a paid path for legacy GMS2 work and console ports.
If a developer is choosing an engine today and expects to sell the result, a free commercial tier removes the upfront license cost that new projects otherwise absorb. By tying the free tier to GMRT, Opera also steers new adopters onto the forward-looking runtime, which concentrates future feature requests and community contributions on the GMRT codebase.
Giving away the runtime while it is still in beta carries a trade-off. A commercial release built on an unfinished runtime can fail in the field, and the developer absorbs that failure. Opera’s payoff is adoption, since every GMRT game shipped in 2027 promotes the runtime and a larger install base feeds the source-access community the company is trying to build.
The GX Games target points to why Opera can afford the free tier. Opera owns both GameMaker and the GX browser, so a free commercial runtime that steers developers toward web and GX Games builds the browser’s games catalogue.
RPG Maker U2U recently landed on Steam with 2.5D creation that does not require Unity. For the indie developers that platforms keep courting, both tools now offer a free entry point and reserve their paid tiers for specialized needs.
The company’s view
Russell Kay, Head of GameMaker, tied the change back to the engine’s original mission. “From the very beginning, GameMaker has been committed to making game development more accessible and flexible for every creator out there,” he said. “As GMRT continues to roll out in beta across platforms, we are widening the scope of what we provide to developers.”
