Is Melty right for you?

Melty suits Windows players who want an existing mashup installed in one place. Its SkyCraft example puts a Minecraft player into Skyrim. For a new idea, use the coding-agent workflow. Check the individual project’s requirements before downloading; the launcher does not promise that every pair of games will work.

A good fit for

  • Playing published mashups with games you already own.
  • Inviting friends to a project that supports multiplayer.
  • Creating a small mod with Claude Code or Codex.

Know the trade-offs

  • Windows is the advertised platform; macOS and Linux support is unconfirmed.
  • Games and coding-agent access can cost extra.
  • Publisher claims are checked against public pages; no installer or mashup was tested.

Melty AI features

Install and launch with Play

Choose a published mashup and press Play. Melty says it downloads the project, installs its dependencies and starts the game. If a required game is missing, the launcher points you to its store. Uninstalling is described as restoring the changed files.

Official documentation

Share a multiplayer invite

On supported multiplayer mashups, Play provides an invite link. Keep the lobby private, share it with friends or make it public. Multiplayer depends on the selected project; installing the launcher alone does not add it to every game.

Official documentation

Create with Melty AI and a coding agent

The Melty AI workflow uses instructions copied from the app into Claude Code or Codex. Describe the mechanic you want; the agent builds and publishes the mashup. The public site explains this handoff but does not expose the full instruction text.

Ways to use Melty

Try SkyCraft with Melty AI

Melty describes SkyCraft as Skyrim played as a Minecraft player. Check that you own both games and meet the project’s requirements before starting.

Play with friends

Choose a mashup marked for multiplayer, start it and share the generated invite. Use the project’s own requirements to prepare each player’s setup.

Build one new mechanic

For a first Melty AI project, specify a host game, one mechanic and a test plan. Ask the agent to explain changed files and how to remove the mod before publishing.

Melty: common questions

What is Melty AI?

Melty AI usually refers here to the game-mashup launcher at melty.gg. The product’s name is Melty. It installs published projects and describes creation through Claude Code or Codex.

Source
Is Melty AI free?

Melty says the launcher and its mashups are free. That excludes the price of required games and any coding-agent access used to create a project.

Source
Does Melty AI work on Mac?

The download page advertises Windows. The reviewed pages do not establish macOS or Linux support.

Source
Can Melty AI combine any two games?

The site makes a broad game-combining claim, but Play works on a selected, published mashup. For an unlisted idea, the documented route is to create a project with a coding agent. Compatibility still needs checking.

Source
Do I need both games?

Melty says mashups run on games you own. Read the specific project’s requirements; a missing game leads to its store.

Source
Is this the Melty AI code editor?

The earlier Melty code editor belongs to meltylabs/melty and references melty.sh. This page covers melty.gg, listed by Y Combinator under David Miller in Fall 2026. Check the domain to distinguish them.

Source
Is Melty AI safe to install?

Melty says uploads are checked for dangerous files and can be reported. We have not audited the Windows installer or tested its file-restoration claim.
