Introducing SpaceBuilder
Thank you for using SetFN SpaceBuilder🙂
SpaceBuilder is an installable piece of software that lets you build your own online space directly on your computer.
The computer where you install SpaceBuilder acts as the server. Files and service settings are kept in storage selected by the operator, and other devices can connect to this server through a local-network or external access address.
Inside this space, you can use:
- A Workspace for managing files and collaborating with your team
- A WebSpace for building and publishing websites and databases
- Plugins that help you make even better use of your space
Distinguish the server from client apps
The installable SpaceBuilder software is the server that provides Workspace and WebSpace. A browser, Windows Space, and Android Space are client apps that connect to this server's address. Anyone can get started with the free Space apps and connect to a workspace operated by a friend, community group, or company. Each person who uses an app does not need to deploy SpaceBuilder themselves.
To connect to a specific workspace, its SpaceBuilder server must be running and reachable from the device you are using.
In the installation table below, Windows (not currently available) refers to installing the SpaceBuilder server on a Windows PC. It does not refer to the Windows Space client app.
Where can you install it?
- A PC at the office or at home
- A laptop
- A small computer such as a Raspberry Pi
- An in-house server or a cloud VM
How can you use it?
- In-house groupware/collaboration tool: Keep it on an office PC and use it like an internal cloud your whole team shares
- Home server: Install it on a home PC and use it as your own personal cloud for files and photos
- Repurposing idle hardware: Turn an unused laptop or old PC into a server
- Dedicated lab/research server: Run it as a dedicated server for sharing research data or large files with your team
- Low-power always-on server: Install it on a Raspberry Pi and run it around the clock without worrying about power consumption
If the PC loses power or the executable is closed, your workspace connection is cut off as well.
Who is it a good fit for?
SetFN SpaceBuilder is well suited to the following kinds of users and organizations.
- Users who want to build their own online space
- Teams concerned about ever-growing SaaS subscription costs
- Organizations that find it difficult to entrust company documents and data to an external server
- Teams that frequently work with large files such as design files, video, research data, or medical images
- Users who want to run websites, file space, databases, and plugins together on a single server
What makes SpaceBuilder a good choice?
SpaceBuilder's key strengths are as follows.
| Feature | Description |
|---|---|
| Local installation | Install the Linux binary on your own PC, an in-house server, an ARM server, a GPU workstation, and more. |
| Data sovereignty | Files and configuration data are stored on hardware your organization controls. |
| Local network speed | Within the same network, you can take advantage of internal network speeds to share large files quickly. |
| Workspace | Manage files, folders, comments, chat, notifications, and activity history, and use a folder as a board. |
| Plugins | Connect features such as email, calendar, and workflow to Workspace after installing and configuring the required plugin. |
| WebSpace | Deploy website files, then deploy a schema as a database and APIs for operation. |
| AI connections | Optionally prepare a local embedding model and knowledge index for contextual search (RAG), or have an administrator configure MCP to connect an external AI. |
Guides for using the product
- Workspace overview: Review files, folders, and team and personal spaces.
- Use a folder as a board: Use a list or feed board inside a folder.
- Use chat: Use all-team, group, and 1:1 chat.
- Plugin overview: Check installation requirements for email, calendar, and other plugins.
- WebSpace overview: Follow the flow for deploying a website and creating a database and APIs.
Contextual search (RAG) requires a local embedding model and a completed knowledge index. An external-AI MCP connection requires an administrator to set its allowed scope and connection key, and selected data may be sent to the external AI provider.
Choosing an installation method
SetFN SpaceBuilder documents installation paths that are available or being prepared, depending on your operating system and deployment method.
| Environment | Description | Installation guide |
|---|---|---|
| Linux (recommended) | Install on a desktop or server environment. | Install on Linux |
| Docker (not currently available) | Run the same environment regardless of OS using a container image. | Install with Docker |
| Windows (not currently available) | Install via WSL on Windows 10 (version 2004 or later) or Windows 11. | Install on Windows |
| macOS (not currently available) | Install on Apple Silicon or Intel Mac. | Install on macOS |
Server and GPU environments
SetFN SpaceBuilder can be used not only on regular PCs but also in server and AI-accelerated environments.
| Environment | Description |
|---|---|
| Docker / Kubernetes | The official container image is not yet available. For now, use the direct Linux installation method. |
| ARM64 Server | Run Workspace on low-power ARM servers or edge environments. |
| NVIDIA GPU | Accelerate AI workloads such as local LLMs, embeddings, and large-scale indexing with a GPU. |
If you plan to operate a server or make active use of AI features, it's a good idea to review CPU architecture, memory, disk, GPU, and network configuration before installing.
