Games Like Roblox: Social Worlds and Creation Tools Compared
Roblox's real draw is not one game, it is a platform: millions of small user-made experiences, an avatar and social layer that ties them together, and tools for anyone to build something new. The six platforms below take different pieces of that idea, some lean harder into building, some into simple hangout chat. None of them is a straight Roblox clone, and we say where each one falls short of it.
Checked: 21 September 2026How we compared these
We looked at what you can actually build or do without paying, what the platform is built for first (games, social chat, or general 3D creation), what devices it runs on, and how new content typically gets made, by the platform's own creators, by individual users, or both. Every entry links to its official site so you can check current terms yourself. We have not run our own hands-on tests of these platforms; descriptions of what each one supports come from official documentation and store pages.
MapRaiders is not a Roblox-style creation platform, we mention it here only because readers comparing shared online worlds often ask where it fits. It combines real-world walking, running or cycling with territory strategy on a shared map, plus a collectible card game with commanders and decks played at home in a PvE/PvP arena. It is in development and open for beta registration, not yet publicly playable.
The six alternatives
Minecraft
Good for: deep building and survival, on your own server with full control over rules and mods (Java Edition) or on console/mobile with simpler setup (Bedrock Edition).
Limits: there is no built-in social lobby or matchmaking the way Roblox has; you join a specific server by address or invite, and content sharing usually happens outside the game (a texture pack or a mod site) rather than through an in-game store.
Developed by Mojang Studios, published by Microsoft. A one-time purchase, about $29.99 for the PC bundle and around $30 on consoles, from about $6.99 to $7.49 on mobile depending on store and platform. Available on Windows, macOS, Linux, ChromeOS, Android, iOS, PlayStation 5, Xbox Series X|S and Nintendo Switch.
Fortnite Creative / UEFN
Good for: building and publishing your own minigame or map inside Fortnite's existing player base, using either simple in-game Creative tools or the more advanced Unreal Editor for Fortnite (UEFN) for full custom logic with the Verse programming language.
Limits: published islands live inside Fortnite's ecosystem and rules, you're not launching an independent app; UEFN's deeper features have a learning curve closer to real game development than Roblox Studio's beginner-friendly scripting.
Developed and published by Epic Games. Free. UEFN and Creative content is available on PC, mobile and console wherever Fortnite runs.
Official site: fortnite.com/developer
VRChat
Good for: social hangouts in user-made 3D worlds and avatars, usable in VR or on a flat screen with mouse and keyboard.
Limits: VRChat is built around social spaces and avatars rather than gameplay minigames; there is no central storefront for buying content the way Roblox sells Robux items, custom worlds and avatars are typically shared through the Unity-based creation tools and community links.
Developed and published by VRChat Inc. Free forever. Available on PC via Steam (no headset required) and on Meta Quest, Pico and Viveport for standalone VR.
Official site: hello.vrchat.com
Garry's Mod
Good for: sandbox physics play and community-made game modes built on the Source engine, with an enormous library of user-made add-ons through the Steam Workshop.
Limits: it is a one-time paid PC purchase, not free like Roblox; the interface and modding workflow are aimed at players comfortable with more technical, PC-centric tools rather than a phone-friendly experience.
Developed by Facepunch Studios, published by Valve. About $9.99 on Steam. Available on Windows, macOS and Linux.

Second Life
Good for: an open-ended virtual world with a long-running user economy, where residents build, script and sell their own objects, clothing and land.
Limits: the desktop client has a steeper learning curve than Roblox and an older-feeling interface; its official mobile app remains in beta with more limited features than desktop.
Operated by Linden Lab. Free to join, with an in-world economy using Linden Dollars for land, goods and services. Primarily a Windows/Mac desktop client, with a mobile companion app.
IMVU
Good for: avatar-based social chat and customization, with a large marketplace of user-made clothing and furniture.
Limits: IMVU is centered on chat rooms and avatar looks rather than playable minigames; most meaningful customization runs through its Credits currency, which can be earned slowly or bought.
Operated by IMVU Inc. Free to download, with optional Credits purchases for premium items. Available on desktop, iOS, Android and web.

Frequently asked questions
Which of these is closest to Roblox's mix of games, social chat and building tools?
Fortnite Creative and UEFN come closest to Roblox's model of many independently built experiences under one platform and one player base. VRChat and Second Life lean more toward social space and avatar customization than gameplay minigames.
Is any of these free with no purchases at all?
Fortnite Creative/UEFN and VRChat are free with no required purchase to use their core building and social features. Roblox, Second Life and IMVU are free to join but built around an in-platform currency for extra items.
