2. Show HN: Instantly visualize any codebase as an interactive diagram
Author: ahmedkhaleel
Description: GitDiagram is an open-source micro dev-tool that I made this past week
Given any public GitHub repository it generates diagrams in Mermaid.js with Claude 3.5 Sonnet
I extract information from the file tree and README for details and interactivity (you can click components to be taken to relevant files and directories)
Also, you can replace "hub" with "diagram" in any repository URL to access its diagram
I created this because I wanted to contribute to open-source projects but quickly realized their codebases are too massive for me to dig through manually, so this helps me get started
I do still plan on adding other features like private repository access if that becomes a thing people want
This project was heavily inspired by https://gitingest.com/ so make sure to check that out as well!
Hopefully this tool can help you and feedback is always welcome!

3. Show HN: I made a web app to bring children's drawings to life
Author: vikmex
Description: Hey HN!
I used to spend hours drawing all kind of things as a kid. Sadly though, those drawings are long gone.
Inspired by this, I created DoodleDreams. A webapp that brings drawings to life using AI and stores them as memories. You can always look back at the drawings, see who made them, and even know the age they were drawn at.
I thought it was a fun way to preserve those memories. What do you think?

4. Show HN: Minimal, self-hosted exercise tracker
URL: https://github.com/bmtwl/exerciseminimilism
Author: DrPhish
Description: After decades of tracking my exercise programs in progressively more complex spreadsheets I eventually burned out on metrics and complicated periodization programs to the point where I had almost stopped exercising.
I am now at a place where I simply want the minimal amount of structure and tracking to make sure I can maintain my fitness, so I boiled the entire concept down to what I felt was its essence: enough information and structure to remind you of what is needed today, and how it went on the same exercises last week.
To reduce friction, the interface is kept as simple as possible. Simple to the point where all setup is done by editing the html source file and there is only one freeform "weight" textbox per exercise to manipulate. Data is autosaved as it is entered. It never nags or judges you except by showing the last date you entered data in for that day-of-the-week's exercises. The only quality-of-life feature is a super-simple rest period timer in the footer.
It has no external dependencies and only uses browser local storage. There is no possibility of monetizing it.
I was on the fence about sharing since it is such a small and simple project, but decided I would share here in case anyone is looking to make a fresh start in the new year and finds the philosophy appealing.

7. Show HN: NeatShift – Organize Windows files with symbolic links
URL: https://github.com/BytexGrid/NeatShift
Author: BytexGrid
Description: Hi HN,
I built a lightweight Windows tool to organize files by relocating them while maintaining their accessibility through symbolic links.
The idea came from needing to tidy up my cluttered file system without breaking file paths used by other applications. NeatShift solves this by automating symbolic link creation whenever files or folders are moved.
Key Features:
- Relocate files without breaking existing references.
- Automatic system restore points for added safety.
- Modern Windows 11-style UI with drag-and-drop support.
- Manage and validate symbolic links easily.
It’s free, open source, and still evolving, so I’d love to hear your feedback, suggestions, or contributions!

8. Show HN: I made a stupid simple but 100% free web analytics
URL: https://www.indielytics.link/
Author: Avfrosta
Description: TLDR: I made a public only web analytics without signup. Stores views and visitors for 10 days before deleting data.
Exactly 25 days ago today I posted here, proud of my new web analytics. The response was mixed and my post even got flagged (understandable). It was my first real launch and I actually made a sale just a day later of 49$(!). Back then my project was pay once, keep forever. Since then I have sadly went over to the dark side (subscription based).
Anyways, I never went back to look at the post after the first two hours, turns out I got a lot of answers. Most answers was something like: "Yea yea, this is great... but why not self-host?". And to be honest, I don't really have a good answer to that, I myself used to self-host.
Since swithcing over to subscription based I have gotten two customers, altough one cancelled. So at the moment I have one subscription based customer. And while I'm not planning to shut it down anytime soon (not very expensive to run) I am looking forward to new projects.
As a way to create a little "boilerplate" for myself I created my latest project Indielytics. It's a stupid simple, public only, free to use web analytics. By adding a small js snippet to your html you will automatically start displaying daily unique visitors and views on www.indielytics.link/your-domain.
It's GDPR compliant and cookieless too. One of the big cons: data is kept for only 10 days to make sure I can afford this.
How it works: the script in your websites HTML sends the domain, user-agent and ip-adress over to my servers. To then be able to count unique visitors without storing any personallly identifiable information (PII's) the IP-adress is first trunctuated (last segments is discarded). After that the domain + user-agent + IP-adress is hashed with a daily rotating salt. Then it's stored in a EU hosted DB. The raw IP-adress is never stored anywhere other that in memory (altough it can probably be found in your server logs). The hashed strings are deleted withing 24 hours.
Vulnerabilities: Right now there are some big cons to the way I have done this. The biggest problem being the fact that a lot of fake requests could easily be sent to my endpoint and thus increase the number displayed for a websites analytics. With simplytics.dev this wasn't really a problem, since theres no reason for people to fake their own data.
But the purpose of Indielytics is to display your analytics to others, which I fear will draw a lot more users with malicious intent.
I'd love feedback on the project, and I'd also love to hear solutions to my above mentioned problem.

9. Show HN: We've built a funny GitHub Wrapped video summary for developers
URL: https://rendley.com/wrapped
Author: bgrigore
Description: Hey everyone, my friend and I created a GitHub Wrapped video for developers to showcase their activity on the platform in a more fun way. The implementation is open-source (https://github.com/rendleyhq/github-wrapped-2024) if you're interested in how it was built.
To get a bit geeky, we used masks, keyframe animations, luma key shaders to remove the background from the confetti video, and some other techniques. Also, everything is rendered directly in the browser!!
I'm curious to hear your thoughts on the rendering performance, especially if you're running this on your phone (hopefully not through an embedded browser).

11. Show HN: I built a mental health app to fix mine
URL: https://milburn.vercel.app/
Author: rkrithik
Description: Hi HN,
I’m still in college and new to the startup world, but here is my first shot at a side project: Milburn, an integrated therapy+journal tool(https://milburn.vercel.app/). I built Milburn bc every mental health tool I could find was missing something: the therapy apps didn’t have voice/memory/too expensive, and the journal apps were always a PITA to sync with therapy.
We trained the chatbot’s model on specific therapy modalities(I personally need CBT sessions, but we also have others like DBT), and then created a prompted journal, added a feedback loop, voice capabilities, and a triage questionnaire.
We’re clearly still at a super early stage and new to this lol, so we would appreciate any feedback on the tool/idea: What resonates? What’s missing? Is this different enough to the myriad other mental health apps on the market? I’d especially appreciate insights from those who’ve worked in mental health tech or have experience with similar tools.
We’re also looking for beta users so drop me an email at [email protected] if you’d like some free access!

Description: TLDR: I'm learning Go and [this](https://github.com/ItzaMi/compare-supermarket-prices) is my first project with it. What am I doing wrong and what could I improve?
In an attempt to expand my horizons and actually get into backend development, I've decided to learn Go. I picked it for no reason other than the market seems to be in a friendly state towards it, compared to Elixir, but I'm very much enjoying it.
Thankfully something unlocked in my brain and I thought of a project to do while learning the syntax and how the language works, so I've built a scraper.
Here's the link: https://github.com/ItzaMi/compare-supermarket-prices
At this point, I would like to know what I'm doing wrong and what I could improve in it, so any tips and advice would be very much appreciated!

13. Show HN: Tysm, a Rust crate for using ChatGPT with Structured Outputs
URL: https://github.com/not-pizza/tysm
Author: ChadNauseam
Description: Hi HN! This Christmas I made tysm, a rust crates which simplifies using ChatGPT with Structured Outputs. Essentially you just tell it the rust type you want the output to conform to, and it handles creating the JSON Schema, passing it to ChatGPT's chat-completions API, and deserializing the response. Structured Outputs are very useful because they guarantee that the response will conform to whatever type you expect. I'm already finding my crate very useful since I love using Structured Outputs but I hate writing JSON Schemas myself.
Technical details for rust heads: To generate the JSON Schema, it uses an unreleased version of the schemars crate. (Hopefully it will be released soon and then I won't have to put up this disclaimer anymore.) For deserialization, it uses serde.

19. Show HN: I built an AI emoji generator for ones that can't afford Apple AI
Author: tuantruong
Description: Hi guys,
I noticed many iPhone users can't access the new AI emoji features because they have older devices. So I spent 48 hours building an accessible alternative using open-source images models.
The system uses a fine-tuned Flux AI model (based on https://github.com/kijai/ComfyUI-FluxTrainer) to generate custom emojis from text. It runs efficiently enough to work on a basic web interface - no device requirements or OS updates needed.
Just type what emoji you want (like "happy pizza doing backflip"), and it generates a vector emoji with transparent background in about 5 seconds. Works on any device with a web browser, including older iPhones.
iOS and android versions are coming, and would love your feedbacks on the tools. Love to hear if something else interesting you would like to see on the too,
Cheers, //TT

21. Show HN: DocIngest – Download and save documentation from any URL
Author: amaldavid
Description: Have been getting tired of having wrong version api docs for building anything with LLMs, just wanted to curate all latest api docs in a single place and also let it be discoverable for others.
It is integrated with firecrawl to pull any website data and make it available as md(markdown) file, yet to add bells and whistles or even guardrails to it. But hope you folks find it useful.
I had previously built https://github.com/Amal-David/gitbook-downloader but whenever i tried to extend to other docs format, had to write a lot of code so just went with firecrawl for now. Stumbled upon gitingest and loved their UI so took that as a reference and built the platform. Some limits of 250 pages max and some sites not fully supported. Feel free to give any specific feedback, will try to progressively iterate on them.

23. Show HN: Acting as Claude's Research Helper in AI (Sheaf Cohomology and LLMs)
URL: https://fixmydocuments.com/blog/01_acting_as_claudes_research_helper_in_ai
Author: eigenvalue
Description: I had a blast writing this blog post and learned a tremendous amount. I suspect that we will soon see a blizzard of papers where the researcher/author isn't just "assisted" by really smart AI models, but rather where the human author becomes more of a research assistant/facilitator! That is, the model itself would dictate the core direction the research should take, with some feedback and input from the human researcher to keep things on track and focused.
The human becomes more of a "token dispenser" and also facilitates cooperation between AI models from different labs (i.e., Claude 3.5 Sonnet and O1-Pro, which I had working together by the end of this).
If anyone reading this is an expert, I'd love to hear your take on whether these ideas have real merit. I suspect they do, since O1-Pro certainly thought so, and I would guess that it would be skeptical of ideas that it knew were generated by its arch-rival, Claude!

Description: Dear HN community --
Merry Christmas, Happy Hannukah, and all the best in the upcoming new year :)
Just wanted to share a crate I've been working on that I finally felt was ready to publish. It's primary purpose is to make it easy to integrate ViteJS with your Rust project. It tries to be a low-touch integration so you can continue using ViteJS as you normally would.
The next step for this is to show the community how you could integrate this into templating engines and web frameworks like actix-web/axum/poem/etc. I've previously drafted a ViteJS integration for Rust backends[1] in create-react-app and I hope to adapt that to use vite-rs soon.

URL: https://affiliategeniuspro.com
Author: dlauro
Description: At the end of last year, I tried to make money with a blog and affiliate marketing. I realized how difficult and tedious it was to keep all the product links updated. While there are some tools and WordPress plugins that help with this, none of them met my needs. So, this is a “scratch my own itch” story.
I made Affiliate Genius Pro to help me manage all my links in one place, and when I need to update the target URL of one of the link, it will update the target URL across all my sites / posts / blogs.
I was going to wait a little bit before launching my project, however I got fired right before Christmas and I have little money and a family to support. So I'm launching at least the MVP to get feedback and keep improving it.
To stay accountable and make the process more enjoyable, I’ve decided to do what’s called “building in public.” I’ll share my progress on social media, the work I need to do, and what I’ve accomplished (or failed to accomplish) to document the journey.
This is the URL of my project: https://affiliategeniuspro.com

URL: https://plotcode.com
Author: jtnguyen
Description: Hey HN
Wanted to share my recent side project.
I found it was a pain having to navigate through multiple places to find relevant patterns or snippets of code for AWS CDK and Pulumi.
Thought why not combine patterns across multiple cloud providers into one place with search and filter.
The most interesting part of the project was trying to optimise the site for mobile and lower-end devices. Came across the concept of "adaptive loading"[1] from Google and Facebook (2019).
The current implementation is naive but the site renders a virtualized list or the entire list based on the number of logical processors detected.
It's a very basic proxy for performance but is also not reliable. For example, the Brave browser reports a false number of logical processors to avoid telemetry[2].
Was wondering if anyone had any thoughts or experience with this?
Open to suggestions or feedback!
Tech:
Frontend - Nextjs 15 hosted on Cloudflare pages as a static site.
Backend - Patterns are primarily sourced from the AWS CDK[3] and Pulumi[4] example repos.

Chinese Record allows users to browse through a curated catalog of Chinese media and find detailed information about each item, including a synopsis, links to streaming platforms, trailers, and more.
I’d love to hear your thoughts and feedback on the site!

Author: fforflo
Description: The xi (ξ) correlation coefficient proposed by Chatterjee, quantifies the degree of dependence between two variables X, Y. It is 0 if and only if the variables are independent and 1 if and only if one is a measurable function of the other.

46. Show HN: I made an app that generates Product Hunt badge regardless of your rank
Author: auden_pierce
Description: My products this year didn't reach the top spots on Product Hunt...
...but I still wanted a badge on my website!
So I did, added some code and voila, the "17th product of the day" badge is on the website
Simple enough. It probably should've ended there
But then I thought. "Maybe, someone else might also want a badge? Wouldn't it be cool to make a web app for this..."
And so, badgemy.app is born!
It's free of course. Maybe it'll save you 10-30 mins!
Add a badge to your website and end the year on a high
ps: I don't know how useful this really is but I guess I just wanted to build a website. Would love your feedback!

55. Show HN: KidTales – Generate children's stories with AI
URL: https://www.kidtalesai.com/
Author: ryleyrandall22
Description: Like a lot of parents, my kids badger me for a bedtime story every night.
We’ve recently started using ChatGPT to come up with them, and after I would ask it to make some images of the story as well.
One night I thought the classic “there should be an app for that”
Only took two days to get the current product built
Current features
- generate an entire story or interactive mode and choose your own adventure
- generated stories you can press play and have it read to you all the way through
- create reusable characters so you can keep a predictable cast between stories
Stack
- Devize (app platform)
- Open AI for AI
- Flux for image generation
- been wanting to try cloudflare workflows as well, so I’m using that to handle the story generation pipeline
The hardest part was getting the images to be consistent between pages. Still not perfect, but honestly my kids like the variation (feels like a surprise on each page)
Would love feedback from any parents!

Description: Hey all!
I recently built a new, improved, and open-source chrome extension that allows you to access, track, and manage your clipboard's history! It's very useful for things like refactoring code, finding obscure commands, and backing up form data.
Existing solutions are either closed-source, slow, riddled with ads, or all of the above. My goal is to make this extension the most trustworthy, performant, and easy to use version! Your feedback would be very much appreciated, thanks!

URL: https://www.booguide.space
Author: ItsDaivy
Description: Hey HN!,
I'm software engineering student who likes to read a lot.
I realized people in my country just read 2.5 books per year.
So I built booguide for two reasons:
1. To make the people compete for who read more books.
2. Encourage reading so that we can read more.
It's really simple but it can have huge impact. I would love if you give me feedback about it please.
