NutriTrace: self-hosted nutrition and wellness tracker (AGPL, single Docker container) (lemmy.world)

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.

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?
[–] TraceApps@lemmy.world 1 points 5 hours ago (1 children)

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.

[–] ProfessorScience@lemmy.world 1 points 2 hours ago

If you're going to work on CSV import anyway soon, then I'll just wait. Thanks!

[–] danielquinn@lemmy.ca 15 points 2 days ago (1 children)

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.

[–] quick_snail@feddit.nl 3 points 2 days ago* (last edited 1 day ago)

At least a mirror. GitHub is authwalled even for GET requests more and more these days

[–] imetators@lemmy.dbzer0.com 5 points 2 days ago (1 children)

Vibe coded, innit?

[–] Dumhuvud@programming.dev 8 points 2 days ago (1 children)

Yeah, the first commit is 47k SLoC, and Claude is mentioned as a "co-author".

[–] TraceApps@lemmy.world -2 points 1 day ago

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!

[–] TraceApps@lemmy.world 13 points 2 days ago

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.

[–] Chaser@lemmy.zip 1 points 1 day ago (1 children)

Thanks for sharing! I'm so annoyed of Yazio, that I was close to start developing a simple calories tracker myself. Glad I can just use this instead.

You asked for feature ideas in a comment. How about OIDC support? My wife is good at forgetting (to add) her passwords (to a password manager). So instead of resetting password xyz each week, i installed pocketid and integrated it to every app I host, that supports OIDC.

[–] TraceApps@lemmy.world 2 points 5 hours ago (1 children)

OIDC has been planned, but since now i have had multiple requests, i have started working on it. Will be implemented most likely in next RC release. Keep an eye out!

[–] Chaser@lemmy.zip 1 points 5 hours ago

Awesome! Thanks

[–] Tolookah@discuss.tchncs.de 9 points 2 days ago (1 children)

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.

List of different types of login types: https://integrations.goauthentik.io/

[–] TraceApps@lemmy.world 5 points 2 days ago

Yes indeed! On my future to do!

[–] quick_snail@feddit.nl 2 points 2 days ago

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.

[–] Squizzy@lemmy.world 3 points 2 days ago (1 children)

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.

[–] TraceApps@lemmy.world 1 points 2 days ago* (last edited 1 day ago) (1 children)

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.

[–] Squizzy@lemmy.world 1 points 2 days ago

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

[–] clifmo@programming.dev 2 points 2 days ago* (last edited 1 day ago)

Sqlite only? Edit: confirmed. And it's written in a way that it will likely only support sqlite in the near future

[–] ProfessorScience@lemmy.world 6 points 2 days ago

Ooh, I'll definitely give this a try.

[–] muxika@piefed.muxika.org 5 points 2 days ago

This is perfect, thanks for sharing.

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?

[–] TraceApps@lemmy.world 1 points 1 day ago (1 children)

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.

More soon.

Quick update on this. Translation infrastructure is live as of v1.0.0-rc.6 (released today). The source file is src/i18n/en.json — about 210 keys covering navigation, page titles, the full auth flow, the onboarding wizard, primary actions in Diary / Foods / Goals / Profile, the AI assistant FAB, and common toasts. Server-side strings (email subjects, push notification bodies) are out of scope for now.

Full workflow is documented in CONTRIBUTING.md → Translations.

About 30% of the client-side surface is extracted in this batch — the screens every user touches every session. Wellness sync messages, deep Settings sub-section labels, and Statistics chart internals are the main gaps. If you hit a screen you use heavily that's still English while translating, open an issue listing the screen and I'll pull it forward in the next extraction batch.

Tag me on the PR when you're ready.

[–] diminou@lemmy.zip 1 points 2 days ago

I'll help with French if you go that far :-)

[–] Lemmert@reddthat.com 1 points 2 days ago (1 children)

Personally I'm more than happy to cover the Dutch translation if you have the time to get translations working. Thanks for the project!

[–] parson0@startrek.website 1 points 2 days ago

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.

[–] loanrangerofpeanuts@lemmy.world 5 points 2 days ago

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.

[–] curbstickle@anarchist.nexus 4 points 2 days ago

This is wonderful!

Going to set it up tomorrow and give it a go!

[–] ProfessorScience@lemmy.world 4 points 2 days ago (1 children)

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.

[–] ProfessorScience@lemmy.world 4 points 2 days ago (1 children)

Looks good, so I've got it up and running now. Thanks!

[–] hoover900@ani.social 1 points 2 days ago (1 children)

What all did you do to get it working? I'm stuck with this issue.

[–] ProfessorScience@lemmy.world 1 points 2 days ago

All I had to do was run the pull command again.

[–] ProfessorScience@lemmy.world 1 points 2 days ago

I'm seeing "Could not reach server — retry" on the diary page and when going to enter foods. The diagnostics log has

Hey OP, I opened a PR to add an entry point supporting _FILE secret environment variables

[–] TraceApps@lemmy.world 1 points 1 day ago

PR tested and merged! Thank you!

[–] HumbleBragger@piefed.social 1 points 2 days ago

This seems awesome! Thanks for sharing

[–] pmtriste@lemmy.world 2 points 2 days ago

This sounds great. How does the device support work? What do you think of GadgetBridge support?

[–] irmadlad@lemmy.world 1 points 2 days ago

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.

[–] USSEthernet@startrek.website 1 points 2 days ago

Just deployed the container. I'll check it out.

[–] StrawberryPigtails@discuss.tchncs.de 2 points 2 days ago

That sounds cool! Been looking for something like this for a while!

[–] CosmicGiraffe@lemmy.world 1 points 2 days ago (1 children)

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?

[–] TraceApps@lemmy.world 3 points 2 days ago

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.
