EDIT 2026-05-03: v1.0.0-rc.14 is out and adds a native Android app.

(original post below)
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.
Repo and docker-compose example: https://github.com/TraceApps/nutritrace
Happy to answer questions.
Ooh, I’ll definitely give this a try.
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.
This looks very interesting. I’ll have to load up the container and give it a try at some point in the future. Big fan of the mealie integration since I use that for all my recipes.
Is the docker image public? I’m getting an “unauthorized” error when attempting to pull it. I’m not getting that error for other ghcr.io images. But I’m not docker expert, so I may be doing something wrong.

Should be fixed now, package was set to private by default on first push. Just flipped it. docker pull ghcr.io/traceapps/nutritrace:latest works without auth now. Thanks for flagging it.
Looks good, so I’ve got it up and running now. Thanks!
I’m seeing “Could not reach server — retry” on the diary page and when going to enter foods. The diagnostics log has

This sounds great. How does the device support work? What do you think of GadgetBridge support?
I have exports of my nutrition and weight info from other apps as csv files, and I’d like to import that data if I can. It looks like Nutritrace can export to csv but not import that. There is the option to import from a json backup though. If I can massage my data into that json format, does it seem reasonable to use that as a way to import my historical data?
If the answer isn’t “omg don’t do that”, then I have a couple of questions about the json:
- Does each item in the diary array require a matching foodList/meals/recipes entry? Or could I just generate items in the diary array?
- How much do I need to worry about IDs? The “import JSON” option says that it merges with existing data; how would it handle ID conflicts (which I assume could happen normally when exporting and importing anyway)?
- Are there any gotchas you can think of that I should watch out for?
The JSON-massage route may work. Diary items are self-contained snapshots, IDs in your file are ignored on import, and the only real catch is that re-importing a date overwrites the existing entry. Happy to drop the field-by-field shape if you want to go that route.
That said, native CSV importers for the popular apps (MFP, LoseIt, Cronometer, etc) are now on the near-term roadmap (thanks to your suggestion) as the proper path for this. If you can hold off a bit (and use one of the above), that’ll be much easier.
If you’re going to work on CSV import anyway soon, then I’ll just wait. Thanks!
Import feature has been added to app as experimental in latest build (1.0.0-rc9). Please test and let me know how it works for you.
I gave this a shot, but when I press the “preview” button I just get a little popup that says “Invalid CSRF token”.

Hmm… i think i see the issue. The preview / commit upload was missing the CSRF token, so the server was rejecting it before it even read the file. Just pushed a fix. Once you pull it down, hard-refresh the page (Ctrl+Shift+R / Cmd+Shift+R) to grab the new bundle and try again.
Ok, I can import the file now, but some entries are getting messed up. This line, for example, shows up in the diary with the amount “NaNg · 722903 kcal”. And as much as I would like to eat Ginger Peanut Chicken until numbers fail to describe my gluttony, I just can’t afford that many calories.

Thanks for catching this. The Cronometer adapter was treating the parsed gram count as a serving multiplier, so a 750g entry got its calories multiplied by 750. The “NaNg” had the same root cause: the portion was stored as the raw string “750.00 g”, which JS coerces to NaN when the diary tries to multiply it for display.
The layout overlap on the duplicate-day dialog is should now be fixed too (added a divider so the buttons have proper visual separation from the radio options).
Both are hopefully now fixed and pushed in rc.14. Grab the latest package, delete the affected day from your diary, and re-import. Items should hopefully now come in with the right values.
Thanks again for the detailed report.
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.
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
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.
