This is the real app, not a mockup. Whatever you enter in the demo stays in your browser and belongs to nobody.

What you get

One zip. Everything to own it.

Foundation Workspace is the first pass at an open source Notion-style workspace for Foundation Base: a clean, local-first app shell with nested pages, a modern block-style editor surface, simple database tables and lists, publishing controls, read-only embeds, Markdown/CSV/JSON portability, and self-hosting docs. It is built for searches around open source Notion alternatives, self-hosted workspaces, Notion-style app templates, and AI-customizable productivity software while staying honest about scope: the current package is a stable local-first template, and the docs show how to grow it into a PostgreSQL, Prisma, Auth.js, Tiptap, and Yjs-backed workspace after the non-realtime version is stable.

Where your data lives

Current demo data stays in this browser by default.

The model names are aligned with the future Prisma schema.

Public and embed previews render only published page content.

Honest limitation

This is a standard-ready advanced app template, not a full Notion clone.

PostgreSQL, Auth.js, Tiptap, and Yjs are documented as expansion steps rather than required for the static catalog demo.

Questions people ask

Is Foundation Workspace a full Notion clone?

No. Foundation Workspace is a first working open source workspace template with nested pages, a block-style editor surface, lightweight databases, publishing, embeds, and portability. It is designed to become a larger Notion alternative over time without claiming every Notion feature on day one.

Can I self-host Foundation Workspace?

Yes. The package includes local setup docs, Docker Compose scaffolding, deploy notes, and a self-hosting path. The current demo is local-first and static-catalog friendly, with PostgreSQL, Prisma, Auth.js, and realtime collaboration documented as expansion steps.

Can an AI coding agent customize it?

Yes. The template ships with AGENTS.md, CLAUDE.md, Cursor rules, README, customization docs, deployment notes, security notes, and clear model boundaries so Codex, Claude Code, Cursor, or another coding agent can safely modify it.

Does it support pages, databases, publishing, and embeds?

Yes. The first version includes nested pages, an autosaved block-style editor, table and list database views, public read-only pages, iframe embed previews, Markdown export, CSV export, JSON backups, Markdown import, and CSV import.
