In the maker’s words, at launch

Hi HN! Today I’m excited to launch OpenNutrition: a free, ODbL-licenced nutrition database of everyday generic, branded, and restaurant foods, a search engine that can browse the web to import new foods, and a companion app that bundles the database and search as a free macro tracking app. Consistently logging the…

  SnackBase – Open-source, GxP-compliant back end for Python teamsJan 2026 · snackbase.dev · ▲70

  Hi HN, I’m the creator of SnackBase. I built this because I work in Healthcare and Life Sciences domain and was tired of spending months building the same "compliant" infrastructure (Audit Logs, Row-Level Security, PII Masking, Auth) before writing any actual product code. The Problem: Existing BaaS tools (Supabase, Appwrite) are amazing, but they are hard to validate for GxP (FDA regulations) and often force you into a JS/Go ecosystem. I wanted something native to the Python tools I already use. The Solution: SnackBase is a self-hosted Python (FastAPI + SQLAlchemy) backend that…

  Plain Text Nutritional Data Parser2018 · ▲8

  https://github.com/galvez/contagrama Right now I've got a tagger UI and an API that correctly identifies foods you've tagged (from the USDA Food Nutrition Database) and processes gram-amounts from plain text to produce a combined nutritional chart. This is very early stage so more of a call for help: the nutrient chart needs a better design and the API needs work in properly processing g/mg/ml and all the weight conversions defined in the usda_weights table. If you're into nutrition, liked the project and would like to help, drop me a note.

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  I built a hardware processor that runs Python▲983

  Hi everyone, I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution. I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz). The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions.…
