Store Checkout validator, a continuous check for web-store checkout. it visually checks store, its product page, cart and checkout. Kind of cool but it's just an MVP to help the medium/low-end store owners with their website. Targeting people who don't a full time developer :)

* This is my first time actually posting anything on HN. I've been making a DSL for writing sheet music specifically for drums as raw text, inspired by ABC Notation (but of course just for drums). Now writing this I noticed that it's kind of complicated to explain and having a landing page would make my life so much easier. But the gist of it is, you write notation that looks like this: https://gist.github.com/Luigi1…

Very cool. I'm working on something similar, for composing songs with both note-playing instruments and drum instruments. The format is TOML-based, and for melody I was inspired by strudel, but I had considered using ABC notation as well. The home page has an example of the format, and some demo songs: https://songformat.com

European night trains search engine. The plan is not to provide the functionality where user searches for a specific route on a specific date and the engine returns prices. The plan is to provide "tips for trips", e.g. I provide a starting city and it will recommend me interesting trip ideas any time in the future. There are many flight apps that provide this functionality, but no train app. Currently I'm building sc…

Thank you for building this! I might be holding it wrong, but I would like to be able to search for all night trains from a particular origin. Is that possible?

I'm working on a general repo shape/structure linter (language agnostic)[0] - the idea is to enforce things like directory structure, existence of various files (LICENCE, etc.), file naming patterns, jsonpath + schema over json/yaml/toml, absence of potentially malicious unicode. It comes with rule bundles for various languages/presets which can be combined and extended. A goal is for it to be very fast, and useable…

Neat so kind of like Vale but for repo structure rules?

[Colma](https://www.colma.ai/) solo venture, working with my dad who has been in digital marketing for 30 years and has a small agency.

Takes any website, does deep research on who's searching, what your offers are, etc, and then makes a plan and recommendations to get you more visibility on Google, ChatGPT, etc.

These days, there's really no excuse for someone with a website to not be doing these things to get more visibility, and I've found generic LLM advice to be pretty bad. Contact if interested or curious! Currently in pilot stage with a few agencies and website builders.

I do calisthenics 3×/week plus Ironman 70.3 prep, which means my training lives across Garmin, Polar, Withings + FIT files and front-lever sessions that no mainstream app models. So I built one that does both (and have been using for the past 4 years+): logs custom strength moves (front lever, FLAC, ¾ pull-ups), aggregates the connected devices (Polar, Garmin, Suunto, Withings, Apple Health) into one weekly view. Cur…

I had my problem in the calisthenic app space as well. Rowing, cycling, biking, calisthenics. Each sport has such specifics I wish there was an open standard on the data for better interop.

A good generic terminal UI app for reviewing git diffs, making comments, etc...

Lots of these have started popping up, but almost every single one of them is a TUI interface for github, or gitlab. What I'm building is for local git by default, but has an extensible plugin system to support integrating with github/gitlab/azure ado/etc... for their PRs and approvals, but forced in to a single consistent UX and workflow.

Its good enough for basic diff reviews that it has become my daily driver for about a month for reviewing my own stuff before I push changes remotely.
