Including the OS.

PicoStack runs simple HTTP services in C# on a custom-built x64 operating system. 265 KB on disk. ~1 MB of RAM, which includes the OS. Flat monthly pricing. Hosted on servers in Finland, powered by solar panels.

Measured numbers: A Hello World HTTP service
Disk image 265 KB
Compressed image 26 KB
RAM (OS + application) ~1 MB
Compiled handler ~40 bytes
Deployment time < 5 seconds
Starting price €5 / month

You write C#.
We handle everything else.

Write your HTTP service in C# using Visual Studio — the tools you already know. A PowerShell script builds a runnable binary image. You upload it. Your service is live in seconds, behind TLS, with automatic certificate management, source-code-derived security filtering, and a weekly statistics email. No containers. No orchestration. No configuration drift.

01

Write C#

Standard Visual Studio/.NET workflow. Debug locally against our runtime host. No new tools to learn.

02

Build

One PowerShell script produces a binary image. Often just a few kilobytes, sometimes less. Transfers in milliseconds.

03

Deploy

Upload your image. Your service boots, registers its endpoints, and starts handling requests. Under five seconds, start to finish.

04

Observe

Weekly email with request counts, response times, cache hit rate, rejected requests, and energy consumed. Plain language. No dashboards to configure.


What a simple service actually needs.

A Hello World HTTP service. Same purpose, different assumptions about what it requires.

Conventional figures represent a typical Linux + Docker + Node.js deployment on a major cloud provider's smallest production-suitable instance.

We measure the watts.
We tell you the number.

Our server's power draw is measured directly from hardware. Divided by the number of services running. Reported in your weekly email — in kilowatt-hours and in terms you can picture, like how many times you could charge a smartphone. No sustainability report. No aggregate averages. Your number. Every week.

Solar panels on our roof generate approximately five times our annual server consumption. Summer surplus covers winter grid draw. Over a full year, every electron is accounted for.
