Folio

A lightweight, self-hostable CMS. Single Go binary. SQLite. Ships with a default Astro theme. No Docker required.

Why

Most open source CMS options are either too heavy (WordPress, Ghost) or too opinionated about the frontend (Payload, Strapi). Folio is built for developers who self-host on a cheap VPS and want:

• A real Markdown editor out of the box
• A default frontend theme they can swap
• Zero external dependencies: no PostgreSQL, no Redis, no Docker
• One systemd service and done

Requirements

• Go 1.21+
• Node.js 18+ and npm
• Git
• Linux or macOS

Note: Node.js 22 or later is required for the default theme (Astro 6).

Install

Download and review the installer, then run it:

curl -O https://raw.githubusercontent.com/srmdn/foliocms/main/install.sh
bash install.sh

This will:

1. Clone Folio and build the binary from source
2. Clone and build the default Astro theme
3. Create a .env file with a generated JWT_SECRET
4. Run the first-time setup wizard to create your admin account

By default, everything is installed into ./folio/. To use a different directory:

bash install.sh --dir /opt/folio

Running

After install:

cd folio

# Start the backend API (default port 8090)
./folio

# In a separate terminal: start the theme (default port 4321)
cd theme && node dist/server/entry.mjs

For production, run both as systemd services. See docs/configuration.md for all environment variables.

First-time setup

The installer runs --setup for you. If you need to re-run it later:

./folio --setup

This creates the admin account interactively. You can also set ADMIN_EMAIL and ADMIN_PASSWORD in .env instead.

Configuration

All configuration is via .env. See docs/configuration.md for the full reference.

Key variables:

Variable	Default	Description
PORT	8090	Backend API port
JWT_SECRET	(none)	Required. Generate with openssl rand -hex 32
CONTENT_DIR	content/blog	Path to Markdown content
THEME_DIR	theme	Path to the theme directory
THEME_BUILD_CMD	npm run build	Command to rebuild the theme
THEME_SERVICE	(none)	systemd service name to restart after rebuild

API

Full API reference: docs/api.md

Theme

Folio ships with foliocms-theme-default, an Astro SSR theme. The installer sets it up automatically.

To build a custom theme, see docs/theme-contract.md.

Architecture

• Backend: Go, Chi router, SQLite (modernc.org/sqlite, pure Go, no CGo)
• Auth: JWT (cookie + Bearer header) + stateless CSRF (HMAC-SHA256)
• Default theme: Astro SSR (separate repo)
• Content: Markdown files with YAML frontmatter in content/blog/<slug>/index.md
