01Workspace shell

Sidebar page tree, editor canvas, and publish/embed inspector.

03Simple databases

Table and list views with editable properties, sorting, filtering, and CSV export.

Overview

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.

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.

Create your app in three steps

Create My App

One click, one zip, the whole project. Free, MIT licensed, yours to keep.

Create My App

Open it with your agent

Open the downloaded folder with the agent you already use. The package includes project notes so the agent can inspect, customize, and publish it without treating the demo as the final app.

$ cd foundation-workspace
$ claude

Claude Code reads the included CLAUDE.md automatically; it already knows the project.

Customize and install the App Link

Ask your agent to make the project yours, publish a stable HTTPS App Link, and use that App Link for installation on each device.

“Customize this app for me, then help me publish it to a stable HTTPS App Link I can install.”

Foundation Base standard

Use it. Create your copy. Install your App Link.

This app is part of the reusable Foundationbase scaffold. The demo is the original. Your copy is separate, owned by you, and changed by your AI coding agent.

The page is standard-ready. Capture and save real screenshots when this app gets its visual asset pass.

Use the demo

Try the original Foundationbase version first. No signup, no account, and no setup.

Open Demo Link

Create My App

Download a complete editable source package. Your copy is yours; changing it never changes the original demo or anyone else's app.

Create My App

Customize with AI

Open the unzipped folder with Codex, Claude Code, Cursor, or another agent. Paste the prompt and let the agent set up, change, test, and publish.

Demo Link

The original Foundationbase app you can try before creating your own copy.

Preview Link

A temporary test link your agent may use while changing your copy.

App Link

Your stable published app URL. This is the link you install.

Install path

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.
