Build Map
Field guide
For builders & sharers
Specs only help if you can translate them into product decisions. This page is the “so what?” layer for shipping on the real Grok Build / *.grok.me stack.
Full web apps and games on a *.grok.me URL: auth (Google/X/email), Postgres data when published, client interactivity, optional xAI chat/image/video/voice, hub listing, remix culture. If it runs in a modern browser and fits serverless + Neon, it fits.
GitHub/ChatGPT/Apple social login, unlimited free AI for every visitor, durable multiplayer servers, arbitrary native mobile binaries, or published exact Neon GB / log retention. Unknown ≠ unlimited.
Preview uses ephemeral PGLite and iframe popup auth — great for demos, not durable user data. Publish injects Neon + per-app auth so real accounts and rows stick.
Runtime Grok calls spend the app owner’s XAI_API_KEY. Design visitor features carefully: sign-in gates, caps, caching. Image/video are far more expensive than short chat.
Template specs are labeled template. Live Lab re-probes the broker and related endpoints so idp support can change without rewriting prose. Numbers Vercel publishes generically are labeled inferred. Gaps stay unknown — never invented.
Real platform, independent sheet
Endpoints and capabilities described here (Grok broker, Better Auth, Neon/PGLite, Vercel publish, xAI API) are real parts of the Grok App Builder environment. What is “unofficial” is this app as a document: it is a builder-made map + live probe tool, not the canonical help center or support channel.
What “measured” means
Live Lab and Bank smoke tests are server-side HTTP checks against the real public surfaces at a point in time. They confirm reachability and broker idp accept/reject behavior. They are not SLAs, pricing contracts, or promises that nothing will ever change.
What “template / unknown” means
Template claims come from the Grok App Builder skills wired into the sandbox (real product constraints). Unknown means a hard number (e.g. exact Neon GB) is not published here — we refuse to invent quotas. Unmeasured ≠ fake; unknown ≠ unlimited.
When official sources win
If this sheet and official material disagree, trust docs.x.ai, Vercel docs, and in-product Grok settings for policy and billing. Use this sheet for hands-on “what does the broker accept right now?” and builder-template truth.
