Roblox Studio Assistant alternatives

AI assistant that edits Unity and Unreal projects.

• Best for: Unity developers and teams who want an assistant that plans and makes changes inside their existing project
• Pricing: Free trial with 100 credits; Pro $20/month, Advanced $60/month, Ultimate $180/month (as of October 2026)
• Export: Not applicable: Bezi edits your own Unity or Unreal project, which stays yours to build and ship with the engine
• Watch out for: Unreal support only entered early access, with a sign-up for testers, on September 23, 2026, and most of Bezi's documentation is written around Unity.

Paid Unreal Engine plugin for AI agents in the editor.

• Best for: Unreal Engine 5 developers who want an AI agent to build Blueprints, C++ and levels inside the editor
• Pricing: One-time license $284.99 per seat (bring your own AI); Indie $25/month and Studio $80/month (shown as reduced from $100) with monthly AI tokens; annual billing $250 and $800 a year (as of October 2026)
• Export: What it builds is ordinary content in your Unreal project; its FAQ says almost nothing from the plugin ends up in the packaged game because its modules are editor-only
• Watch out for: The macOS build isn't notarized by Apple yet, so a copy downloaded through a browser needs a Terminal command before the editor will load it, per the getting-started docs.

Unity's in-editor AI assistant, generators and MCP.

• Best for: Unity 6 developers who want AI help inside the Editor, or who want to drive Unity from Claude Code, Codex, Cursor or another agent
• Pricing: In-editor assistant included in Pro, Enterprise and Industry; Personal users get a 14-day trial, then $10/month. The official plugin, Unity CLI and its MCP server are free (as of October 2026)
• Export: Yes: everything the tools make is ordinary Unity project content, which Unity builds for 25+ platforms
• Watch out for: Assistant credits don't roll over and AI features pause at zero; Unity says credit rates can change without notice, and the tools are still in beta.

Open-source no-code game engine with an AI agent.

• Best for: Beginners and hobbyists who want a real 2D or 3D engine without writing code, with AI help inside the editor
• Pricing: Free plan with 40 AI credits a month; Silver $7.99, Gold $13.99 and Pro $39.99 a month billed monthly, or less billed yearly (as of October 2026)
• Export: Yes: every plan publishes to gd.games, desktop and Google Play (free plan once a day); iOS from Gold; GDevelop's pricing page says the editor and engine are open source under MIT
• Watch out for: GDevelop's blog says the AI Agent isn't an instant "make my whole game" button; complex systems take several prompts and fixes, and it mainly uses official extensions.
