Sanity

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.

Mkdirs is an open-source Next.js template for building AI-powered directory websites. It provides listings with categories, collections, tags, and search; user authentication and dashboards; AI-assisted submission and content generation; and free, paid, or sponsored submissions through Stripe. Sanity supplies the content management system and blog, while Resend handles transactional email and newsletters. The template also includes SEO, analytics, themes, responsive layouts, and deployment options for Vercel and Docker. It is developed by OpenFox and licensed under Apache License 2.0, with the Mkdirs name, logo, and trademarks excluded from permission to identify derived products.

Webiny is an open-source, self-hosted content platform and headless CMS that runs serverlessly inside the user's AWS account. Its TypeScript framework provides a GraphQL API, custom content models, field-level permissions, localization, versioning, lifecycle hooks, dependency injection, admin UI and infrastructure extension points, and supports AI-assisted development through an MCP server. The platform includes a visual website builder with a Next.js SDK, a file manager for digital assets, publishing workflows with drafts, reviewers, scheduled publishing and audit trails, and native multi-tenancy with isolated data, users, assets and permissions. It runs on AWS Lambda, DynamoDB, S3 and CloudFront, with infrastructure provisioned through Pulumi; optional OpenSearch and VPC configurations are also supported. Webiny is extended through code and can be deployed using open-source infrastructure templates rather than managed servers.

Halo is an open-source website-building and content-management platform for personal blogs, knowledge bases, corporate websites, and online stores. It provides a site-management system with themes and plugins, and supports deployment with Docker or on Linux servers. The Community Edition is free and licensed under GPLv3; Professional and Store editions add features such as mobile content management, AI-assisted site creation, private deployment, and integrated e-commerce capabilities.

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.
