Nexity
Nexity is an open source system for starting and growing AI-native websites on Next.js + Sanity. Its starter, base/, is a pnpm monorepo with two packages:
web/: the Next.js 16 app (App Router, Tailwind CSS 4, TypeScript), with the Sanity Studio embedded at /admin.studio/: a standalone Sanity Studio with the same schemas. Schemas live here and web/ imports them.
This repository holds the starter, a demo site built on it (theme-meridian/) and, in .agents/, the agent layer that works with them: skills and read-only agents (reviewers, auditors) for any coding agent (Claude Code, Codex, Cursor and others).
Stack

| Entry | What you get | How to start |
|---|
base/ | Unbranded starter. Same features as Meridian, neutral look (default Tailwind palette, Inter). Starts on an empty dataset and shows a Next steps screen until you add the first content. | npm create sanity@latest -- --template Pagepro/nexity/base |
theme-meridian/ | Demo site for Meridian, a fictional B2B brand: full design, product mocks and seed content. | npm create sanity@latest -- --template Pagepro/nexity/theme-meridian, then pnpm seed |
.agents/ | Agent skills and read-only agents for setting up a project, creating sections, fixing links, writing alt texts and auditing Sanity use. | Copy or symlink into your project's .agents/ (see Agent layer) |
sanity init creates or picks a Sanity project and dataset, downloads the starter folder, writes web/.env.local and studio/.env with the project id and dataset, creates the API tokens, adds the localhost CORS origins and installs the dependencies. Then:
pnpm dev # http://localhost:3000 (site) and http://localhost:3000/admin (Studio)
Locally, the standalone Studio at http://localhost:3333 (also started by pnpm dev) reloads faster than /admin. Production serves only the Studio embedded at /admin.
In theme-meridian/, run pnpm seed to import the Meridian dataset (pages, posts, case studies, images) into the dataset you picked. The seed replaces documents with the same IDs, so use a fresh dataset.
Each starter has its own README.md and docs/ with setup details, environment variables and deployment notes.

Features
Both starters have the same features. They differ only in look and seed content. The full list for editors and marketers is in each starter's docs/FEATURES.md.
- Page builder: about two dozen ready-made blocks (hero, feature grids, bento grid, split sections, stats, pricing, comparison table, testimonials, FAQ, contact form, CTA, listings and more). Each block has shared options: visibility, light/dark theme, dividers and an anchor ID.
- Content types: pages, blog, case studies, podcast episodes, reusable libraries (authors, testimonials, integrations), shared sections, global sections injected across URL areas, header, footer and site settings.
- Editing: Studio at
/admin on the same domain, click-to-edit visual preview, live draft preview, tag-based revalidation on publish (no rebuilds), and a Sections Gallery with sample content for every block.
- Redirects and rewrites managed in the CMS, live about two minutes after publishing, with patterns, query-string passthrough and loop protection.
- SEO: per-page title, description, share image, noindex/nofollow, canonical and hreflang; generated share images; XML sitemap;
robots.txt with a single IS_INDEXABLE launch switch; schema.org JSON-LD; pre-launch GROQ checks for missing or out-of-range titles and descriptions (docs/guides/before-release.md).
- Content for AI agents:
llms.txt, and every page as Markdown (add .md to any URL).
- Site basics: GDPR cookie consent (c15t), Google Tag Manager by env var, a contact form sent through Resend, image optimization through the Sanity CDN, a PWA manifest.
- Infrastructure as code:
sanity.blueprint.ts sets up CORS origins and the revalidation webhook from env vars.
- Tooling: TypeScript, Sanity TypeGen, Zod-validated env vars, Oxlint and Oxfmt.
- Agent layer:
AGENTS.md (how to build), DESIGN.md (how it looks) and BRAND.md (what it says) give any coding agent the project's rules, plus skills and read-only agents in .agents/. See Agent layer.
Agent layer
Every coding agent working on a Nexity project reads the same files. Nothing in them is tied to one vendor.
