wiki.gg

wiki.gg is a free hosting service for collaboratively edited encyclopedic wikis, built on MediaWiki. It suits communities that want a shared reference space with familiar wiki tools; its free hosting is compelling, but the application and domain limits narrow the fit.

Overview

The service spans gaming, entertainment, open-source, hobby and other general-interest subjects, and says it hosts more than 800 wikis. MediaWiki—the software used by Wikipedia—provides a substantial foundation for collaborative editing. Wiki hosting costs nothing, with advertisements supporting the service.

Getting started is not entirely self-service: each wiki requires an application, accepted case by case, and replies typically arrive in about 5–7 business days. The resulting site uses a wiki.gg subdomain; custom domains are not supported, though URL redirects are allowed. That trade-off works for communities prioritizing free hosting over control of their address.

Key features

New wikis have VisualEditor installed by default, with LinkSuggest and other editor-quality extensions available. Admins can request extensions, but some cannot be installed because they are unmaintained, incompatible, or raise code-quality or stability concerns. This gives communities useful room to tailor a wiki without promising every MediaWiki extension will be available.

Role permissions, revision history, media uploads and API access support collaborative maintenance. Most wikis require editor accounts, which wiki.gg says makes malicious changes easier to trace, revert and block. For Discord-based communities, Wiki-Bot can link wiki pages, surface recent changes and help track edits. The public Discord server also connects editors and offers support and platform guidance.

For structured template data, Cargo’s wiki.gg fork, LIBRARIAN, stores and queries data, but is available only by request and approval. The content policy bars original AI-generated content while allowing AI assistance with text, diagrams and tested code—an important boundary for communities setting editorial rules.

Pricing

Plan	Price	What it means
Wiki hosting	free	Free wiki hosting, subject to application and case-by-case acceptance; wiki.gg subdomain only.

There is no paid tier or custom-domain option in the stated plan. The price is excellent for a community that can work within the application process and subdomain constraint; those who need a branded domain should look elsewhere.

wiki.gg is available on the web.

Who it's for

Choose wiki.gg for a community-run reference wiki—especially a game, entertainment, open-source or hobby project—that values MediaWiki, collaborative editing and zero hosting cost more than a custom domain. It is a weaker fit for projects that need guaranteed acceptance, a branded URL, or a particular extension that cannot be approved.

Pros and cons

• Pros: Hosting is free, and the MediaWiki base plus VisualEditor gives editors familiar wiki-oriented tools without a hosting bill.
• Pros: Revision history, role permissions, media uploads, API access and Discord integration support community upkeep and coordination.
• Cons: Applications are accepted case by case, with replies typically taking about 5–7 business days, so launching is not immediate or guaranteed.
• Cons: Only wiki.gg subdomains are supported, making the service unsuitable when a custom domain is essential.
• Cons: Extension requests can be declined for maintenance, compatibility, code-quality or stability reasons; LIBRARIAN also requires approval.

Alternatives

• World Anvil is another option for world-building, with a free Freeman plan.

Verdict

wiki.gg is a strong choice for a community that wants free, collaborative MediaWiki hosting and can accept a wiki.gg address. Its editing and community features make the no-cost offer useful, but the application requirement and lack of custom domains are decisive drawbacks for projects that need instant setup or a branded home.
