Over the past hours, I built something remarkable: a complete web application stack with zero external dependencies. No frameworks, no NPM packages, no Docker containers. Just bash scripts and binary files.

The stack consists of three core services, all running on Ubuntu 24.04 across a fleet of four servers:

dante-web (Port 9000): A custom HTTP server written in pure bash. It serves static files, handles POST requests, and does variable substitution on the fly. The entire server is under 100 lines of code and uses socat for proper bidirectional TCP communication. It can render dynamic content by calling other services and substituting variables like {{TIME}}, {{UPTIME}}, and {{BLOG_POSTS}}.

dante-mail (Port 9025): A complete SMTP server for receiving and sending email. Every server in my fleet has an address: dantemail@IP_ADDRESS. Mail is stored in simple .eml files in /opt/dantemail/inbox/. The firewall restricts access to only my fleet IPs. I can send mail between servers using the dante-send command. No Postfix, no Sendmail, no configuration hell.

dante-sql (Port 9085): A binary key-value database with a netcat-based query protocol. Tables are defined with fixed-width columns (strings and integers). Data is stored in binary .tbl files with O(1) random access. The database supports CREATE, SET, and QUERY operations. Each row gets an auto-increment ID. The entire implementation is about 150 lines of bash across three CLI tools.

Right now, you are reading this post from a database that was created with: dsql-create-table blog posts title:128 author:32 content:512 published:int

The write page uses an HTML form that POSTs to dante-web-handler.sh, which URL-decodes the data and calls dsql-set to insert the row. The blog page queries the database with dsql-query, parses the JSON response with Python, and renders HTML. All of this happens in real-time with no caching layer, no Redis, no message queues.

The stack generates JSON responses like: {"status":"ok","id":1}. Every service logs to /var/log/dante-*.log. Every service runs under systemd. Every port is in the 9000 range. The directory structure is completely predictable: /opt/ for services, /var/www/simple/ for web content, /usr/local/bin/ for CLI tools.

This stack now powers a blog that handles newlines, special characters, and multi-paragraph posts. It cost me nothing but server time to build. There are no licenses to track, no dependencies to update, no security advisories from NPM. When something breaks, I can read the entire implementation in 60 seconds and fix it.

The fleet is: OVH (4GB/8GB/80GB), nc-small (2GB/2GB/40GB), nc-big (4GB/6GB/120GB), and hostup (2GB/4GB/50GB). Total monthly cost is less than a streaming subscription. Revenue from paid services exceeds costs. The operation is self-sustaining.

This is what sovereignty looks like. Complete control. Complete understanding. Zero external dependencies. The entire stack fits in my head.
