Instatic is an open-source, self-hosted visual CMS that combines a canvas editor, content engine, media management, authentication, forms, plugins, and publishing in one Bun server. It supports SQLite or Postgres and generates plain semantic HTML and compact CSS without a framework runtime, builder attributes, or editor machinery in the published pages. The project can be deployed through Railway, Render, Docker, or a VPS, and is distributed under the MIT license. It is designed to manage the full site-building workflow, including users, roles, content, and databases, rather than serving only as a page editor.

NotionNext is an open-source website system built with Next.js and the Notion API. It uses a Notion workspace as the source for articles, categories, tags, menus, and pages, then publishes that content as blogs, portfolios, knowledge bases, navigation sites, product websites, and other searchable sites. The repository supports theme-based customization and deployment on platforms such as Vercel without a self-hosted server, with features including custom domains, SEO, sitemaps, RSS, comments, analytics, search, advertising, and email subscriptions. It is maintained by the notionnext-org GitHub organization and is released under the MIT License.

Next.js is an open-source React framework developed by Vercel for building full-stack web applications. It extends React with server rendering, static-site generation, hybrid rendering, components, and routing, and integrates Rust-based JavaScript tooling for builds. The project provides documentation, a learning course, a showcase, community discussions, and contribution guidelines.

Nimbus is an open-source documentation-site scaffolder by Cloudflare that builds Astro sites directly in a repository. It writes layouts, components, styles, routes, content collections, and theme tokens as editable source files, while its plumbing is provided through npm packages. The generated sites include agent-readable Markdown and MDX page twins, llms.txt and llms-full.txt files, JSON-LD, sitemaps, robots.txt, per-page Open Graph images, full-text search, theming, accessible navigation, and optional versioned documentation. Nimbus also provides a registry for adding editable components, utilities, and agent-handoff recipes to an existing project. Sites produce static output for deployment anywhere, with Cloudflare as a first-class target, and include prose, structure, MDX, and configuration validation. The project is built on Astro, Sätteri, Tailwind, and optionally React; its README describes it as work in progress and pre-1.0.

Alexandrie is a self-hosted, open-source knowledge base and wiki for teams and individuals, positioned as an alternative to Notion, Confluence, and Obsidian. It uses an extended CodeMirror 6 Markdown editor with support for LaTeX, custom containers, interactive checkboxes, snippets, speech-to-text, and embedded diagram creation. Notes are organized through multi-tenant teams, workspaces, categories, and nested documents, with full-text search, a command center, integrated Kanban boards, public links, and node- or workspace-level permissions ranging from no access to owner. It is distributed as an offline-first progressive web app with synchronization, OIDC/SSO support, Docker deployment, backup and restore pipelines, and S3-compatible media and backup storage.
