Hey all, sharing what I’ve been working on. NutriTrace is a self-hosted nutrition and wellness tracker that runs entirely on your own server in a single Docker container.
I built it because every commercial nutrition app has the same shape. You hand them years of food data, body measurements, and biometrics, and your data is held hostage when they pivot or paywall. I wanted to track macros and pull in my Fitbit data without participating in that.
Daily food diary with multi-ingredient meals, recipes, body stats, water tracking, day-level notes. Personal food database, barcode scanner, imports from Open Food Facts and USDA, plus optional Mealie integration. Statistics with trend charts, full backup, exports as CSV / JSON / full ZIP.
Optional wellness device sync from Fitbit, Withings, Garmin, and Android Health Connect. Sleep / readiness / stress scores computed from your data.
Optional AI assistant where you bring your own Claude / OpenAI / Gemini key. It queries your real data via tool use so it can answer things like “what was my average protein this month” without making numbers up. There’s a voice food logger too. Both fully optional, off by default.
Tech: Svelte 4 + Express + better-sqlite3, multi-stage Dockerfile, AGPL-3.0. Native Android app is in active development; PWA installs to home screen on any modern browser today.

Happy to answer questions.
Vibe coded, innit?
Yeah, the first commit is 47k SLoC, and Claude is mentioned as a “co-author”.
Yes, vibe coded and proud of it. This is a labor of love that I genuinely don’t think I could have completed without Claude Code. The first commit is large because I was working out of a private dev repo and synced everything to the public repo just before the 1.0 RC release. Hope you give it a chance and that it suits your needs. Thanks!
Hey, can you make a much simpler version of this? Just a static site of the USDA data?
The USDA nutrition site went down at some point during Trump’s term. and I was afraid that information was lost forever.
I wish we just had a simple way for folks to clone this website. Literally just that. It would be much simpler than what you’ve already done, and extremely useful.
Hey OP, I opened a PR to add an entry point supporting
_FILEsecret environment variablesPR tested and merged! Thank you!
This seems awesome! Thanks for sharing
Sqlite only? Edit: confirmed. And it’s written in a way that it will likely only support sqlite in the near future
Great project. Looks like a lot of time went into it. I may give it a spin later on this evening. You included screenshots. Thank you for that.
As this is a new project, have you considered hosting your code somewhere other than GitHub? Codeberg and GitLab are similarly user-friendly platforms without the many downsides of supporting Microsoft.
At least a clone. GitHub is authwalled even for GET requests more and more these days
Just deployed the container. I’ll check it out.
How well would this work internationally? More a question on the resources but does open food facts log international barcodes? I knowour stuff is way different to the same product stocked in the US.
Barcodes work internationally. i can confirm because i have used in both europe (italy) and africa (south africa). Only difference between nutrition facts i see is that the US uses Sodium and i want to say that at least Europe uses Salt. I have a built in conversion where when one is used the other is automatically calculated.
Brilliant, I could have worded that better. I assume a mars bar in europe and a mars bar in the US has different barcodes because they are made differently and I wasnt sure if the OpenFoodFacts was a US library but it appears to log barcodes and info globally.
Great idea, love it tackling the subscription creep of trackers
Thanks all, really appreciate the kind words. Feedback is welcome on anything: bug reports, missing features, things that feel rough, or just “this works for my setup.” A few features are flagged Experimental right now and I’d like to harden them enough to drop the badge.
Native Android app is in active development. There’s also a sister project in the works called LiftTrace under the same TraceApps umbrella, same self-hosted Docker setup but for workout tracking (sets, reps, programs, PRs). Not public yet but close.
What does the mealie integration enable? I assume it’s providing foods that can be logged, but can you also pull stuff from mealies meal planning section & populate it into the diary?
Mealie integration allows you to pull in your Meal/Recipe from your self hosted instance of Mealie via api. If you have nutrition facts set there by the recipes total weight, it will pull in that data and then you can set your serving size accordingly so it calculates properly. It also pulls in the recipe pic if set in Mealie.
Is there a place where we could help with translation ?
I know a few people that would want an app like that but English is not their primary language and won’t bother checking it out at all without some kind of translation.

Great question, and not yet. NutriTrace is English-only right now, and the UI strings are hardcoded throughout the Svelte components. To accept translations I’d first need to wire up an i18n layer (svelte-i18n is the obvious pick) and extract strings to per-locale JSON files. Then translation contributions become straightforward via PRs or something like Weblate/Crowdin. I will add this to my roadmap. Any languages in particular we should prioritize?
Thanks for the offers to help with translations. Wanted to share the plan.
I’m wiring up the translation infrastructure now: svelte-i18n with one JSON file per locale in the repo. The workflow once it’s ready is straightforward. There’ll be a single English source file at src/i18n/en.json, contributors copy it to their locale (fr.json, nl.json, de.json, etc.), translate the values, and open a pull request. Keys stay untouched, only values change.
Nothing to do right now. I’ll open a GitHub tracking issue once the source file is stable enough to translate against. A short contributor guide will land with it covering workflow and conventions.
One thing worth flagging early: for nutrition labels specifically, please plan to use the regulatory terms that appear on food packaging in your country rather than the literal English equivalents. So Glucides / Lipides / Protéines for French, Koolhydraten / Vetten / Eiwitten for Dutch, Eiweiß rather than Protein for German, and so on.
More soon.
I’ll help with French if you go that far :-)
Personally I’m more than happy to cover the Dutch translation if you have the time to get translations working. Thanks for the project!
Happy to help with German. I used to get the LoseIt premium for free but haven’t used it in many years. I just assume it’s a privacy nightmare so haven’t bothered opening it. But I like the concept, just tracking helped me improve my diet and health.
This sounds great. How does the device support work? What do you think of GadgetBridge support?
On multi user: any thoughts on working with oidc/ldap or the like? I use authentik at home for many other services and it would be great to keep the single login.

Yes indeed! On my future to do!
Ooh, I’ll definitely give this a try.
