About

The site

Self-Hosted Nutrition is a small, opinionated, one-person publication that started in late 2024 as a personal blog and grew because the existing FOSS-tracker writeups online were either out-of-date or written by people who hadn't actually compiled the apps. It covers four overlapping things:

• Comparisons. Side-by-side reviews of FOSS and commercial nutrition trackers — feature matrices, barcode-scanner accuracy, database depth, last-commit health, license terms.
• Self-hosting guides. Docker, Caddy, k3s, Tailscale, Borg/restic. How to actually run an open-source tracker on your own hardware.
• Privacy. What the commercial apps collect, who they share it with, and how to read a privacy policy without your eyes glazing over.
• APIs. USDA FoodData Central, Open Food Facts, Nutritionix — for people building their own tools.

The editor

Alex Brennan, Editor.

Alex Brennan is a software engineer with a decade in distributed-systems work and a long-standing self-hosting habit. Self-Hosted Nutrition started in 2024 as a personal blog about routing personal health data through a homelab instead of through someone else's metrics pipeline. It expanded as it became clear there was no good single resource on FOSS food trackers, USDA-API plumbing, or threat-modelling consumer nutrition apps. No nutrition credentials — when nutrition science enters a piece, the references go to the literature, not to the editor.

What this site is not

• It is not nutrition advice. There are no nutrition credentials behind this masthead. When nutrition science is referenced, the references go to the literature, not to the editor.
• It is not a recommender. We do not endorse a particular tracker. The position is "self-host if you can; if you can't, here are the trade-offs."
• It is not affiliated. There are no affiliate links anywhere on this site. There are no sponsored posts. There is no advertising.
• It is not telemetry-instrumented. You are reading static HTML served from S3+CloudFront. No analytics, no fingerprinting, no third-party JS. (Verify in devtools.)

Editorial policy

• Every commercial app gets an honest privacy and feature audit, including ones we personally use.
• FOSS apps are evaluated by actually compiling and running them, not by reading the README.
• Corrections are dated and listed at the bottom of the affected piece.
• Anyone who emails editor@selfhostednutrition.org with a verifiable factual correction gets it published, attributed if they want, anonymous if they want.

Methodology
