1. Show HN: Lume – OS lightweight CLI for MacOS and Linux VMs on Apple Silicon

URL: https://github.com/trycua/lume

Author: sandropuppo

Description: We just open-sourced Lume - a tool we built after hitting walls with existing virtualization options on Apple Silicon. No GUI, no complex stacks - just a single binary that lets you spin up macOS or Linux VMs via CLI or API.

Why we built Lume:

• Run native macOS VMs in 1 command, using Apple Virtualization.Framework: lume run macos-sequoia-vanilla:latest

  - Prebuilt images on https://ghcr.io/trycua (macOS, Ubuntu on ARM)

  - API server to manage VMs programmatically POST /lume/vms

  - A python SDK on github.com/trycua/pylume

  Run prebuilt macOS images in just 1 step: lume run macos-sequoia-vanilla:latest

  How to Install:

  brew tap trycua/lume

  brew install lume

  You can also download the lume.pkg.tar.gz archive from the latest release https://github.com/trycua/lume/releases, extract it, and install the package manually.

  Local API Server: lume exposes a local HTTP API server that listens on <a href="http:&#x2F;&#x2F;localhost:3000&#x2F;lume" rel="nofollow">http:&#x2F;&#x2F;localhost:3000&#x2F;lume</a>, enabling automated management of VMs.

  lume serve

  For detailed API documentation, please refer to API Reference(https://github.com/trycua/lume/blob/main/docs/API-Reference....).

  HN devs - would love raw feedback on the API design and whether this solves your Apple Silicon VM pain points. What would make you replace UTM/Multipass/Docker Desktop with this?

2. Show HN: Modest – musical harmony library for Lua

URL: https://github.com/esbudylin/modest

Author: esbudylin

Description: This is a project I've been building in my spare time over the past few months. It's a library that provides methods for working with musical harmony ‒ intervals, notes, chords. For example, it can parse almost any chord symbol (Fmaj7, CminMaj9, etc) and turn it into notes, or it can identify a chord from a given set of notes.

I started this project with the idea of using formal grammar to parse chord symbols. I wanted to use it instead of a hand-written parser, which is the common approach among similar libraries. Lua caught my attention because of Lpeg, a Parsing Expression Grammar library that is both fast and easy to use. An additional motivation for using Lua was the lack of comparable libraries for it, even though the language is commonly used in audio programming.

However, despite being a Lua library, the project itself is written in Fennel — a "lispy" language that transpiles to Lua. Fennel has features that make writing code for the Lua platform much more pleasant: a concise syntax, macros, and destructuring — a feature Lua sorely lacks!

In the process, I definitely learned a lot about music theory, although my new knowledge is quite one-sided. By working on this library, I know a thing or two about types and structure of chords, but I learned almost nothing about their composition and transformation. Perhaps these will be the directions I explore next in the project.

3. Show HN: Groundhog AI Spring API

URL: https://groundhog-day.com/api

Author: pcraig3

Description: For anyone building weather-related AI apps, I am releasing an exciting iteration on last year’s model.

My Groundhog API is trained on 130 years of data and makes use of 82 separate data sources. Similar to DeepSeek, it is completely open source and free to use.

The primary use case is to make inferences about whether spring will come early or not, using a Mixture of Exports (MoE) approach, but surely others can be found if you are creative.

Other use cases:

• All predicting groundhogs
• Where they all live
• Whether they are “real” groundhogs or imposters

  Excited to see what people do with it!

7. Show HN: I Built a Platform to Buy and Sell GitHub Repositories

URL: https://www.gittrader.com/

Author: iliaddh

Description: Hey HN,

I built a platform that allows developers to buy and sell GitHub repositories using private forking. The idea is to help indie developers, open-source maintainers, and teams monetize their work while ensuring buyers get fully functional projects with minimal hassle. Many developers create great projects but lack the time or resources to maintain them. Instead of letting them fade away, why not sell them to someone who wants to continue the work?

Here is how it works:

- Sellers list theis GitHub repos in the platform

• Buyers purchase repos
• Buyers automatically added as collaborators and can fork the repo

URL: https://www.youtube.com/shorts/SHthW2KCtmM

Author: san_tekart

Description: Show HN: FastAPI Realtime Stock Monitor with Python worker threads

I built a real-time stock monitoring demo that simulates market data streams to show how to handle multiple real-time updates in Python without complex dependencies like Celery.

Key concepts:

• Worker threads for background processing
• Event-driven architecture with emitter-listener pattern
• WebSocket for real-time updates
• Clean separation of concerns

  The application uses PynneX (a lightweight Python library) to implement:

1. Signal/slot pattern for event handling
2. Worker thread management
3. Thread-safe task queuing

   Technical stack:

• FastAPI for the web framework
• WebSocket for real-time communication
• ag-Grid for interactive data display
• eCharts for candlestick visualization

  No message brokers, no task queues, no complex setup - just Python's built-in threading and asyncio with a thin event-driven layer.

  Quick start:

  pip install pynnex fastapi python-socketio uvicorn python examples/fastapi_socketio_stock_monitor.py

  Then open http://localhost:8000

14. Show HN: Generate a political compass of characters from a story prompt

URL: https://www.loregrid.com/

Author: kkukshtel

Description: Hey HN — I've been working on creating small games with LLMs for the past year or two and found that one thing they have been bad at generally is creating story worlds — they tend to generate clusters of similar characters that aren't intrinsically linked to each other.

I was thinking about this and remembered the semi-famous alien invasion political compass meme: https://www.reddit.com/r/PoliticalCompassMemes/comments/ktyq...

I really liked how that format enforces the need to fill out all parts of the alignment chart, giving you a rich diversity of characters. So I created a generator that does just that! Additionally, you can open the story panel on the right and select a few characters and click "submit" to generate an ongoing story with the characters.

16. Show HN: Language Learning from YouTube content

URL: https://fluentsubs.com/

Author: ph4evers

Description: Hi!

I'm living as an expat in France and I had a hard time following the news. So I've been working on Fluentsubs that turns YouTube content into a language learning experience.

YouTube videos up to 20 minutes can be transcribed and listened to. At the same time I made it easy to lookup certain words and automatically add spaced repetition cards using the given context. This means that you can also rehearse with a real voice and not with AI dubs.

This works especially well for the somewhat smaller languages that have a small track on Duolingo, and now are desperately looking for content (Norwegian, Finnish, Swedish, etc.)

19. Show HN: Profound – AI therapist and personal coach

URL: https://profoundapp.org

Author: ripped_britches

Description: Profound is an AI therapist and personal coach that will prioritize your privacy, remember you on a personal level, and integrate with therapy tools like assessments and journals. It is available today on ios, android, and web.

--- How it Started ---

I've been an avid user of LLMs (happy to discuss how I use them for coding in a comment thread). But I realized I got much better personal responses by dumping a ton of info about myself into the system prompt. Instead of "general assistant response" it felt much more like "friend that really knows me".

This led me to think about building a high-fidelity long-term memory layer to augment the LLM. This is conceptually similar to the test-time compute paradigm because you give it more time/compute to do memory-related tasks before and after the actual response. It's worked really well for me personally.

This personalization epiphany came around the same time as having personal frustration using other online therapy solutions I'd tried. Not that they weren't qualified professionals, but they just can't really get to know you fully in the short time you have with them. At least that was my experience. This is not to say others don't have excellent experiences, but this happened to me and I'm sure it has happened to others as well.

All of this came together into the idea for a deeply personal AI therapist - one that you could dump everything into (even the most trivial details about your life) and it would accept them with infinite patience and availability.

--- The Stack ---

- Flutter. I love Flutter. This is actually my first Flutter app, but it was an amazing experience. Helped to get launched on android, ios, and web in one fell swoop. Probably #1 feature here is that everything is fully integrated end-to-end. You have this amazing DX console for debugging everything from styling to state to performance.

- Drift + Powersync + Supabase (client-side sqlite DB with centralized syncing to postgres). Also love this setup. Huge shoutout to Simon Binder, open source author of Drift and now engineer at Powersync. This makes Profound a local-first app. Rather than two different storage patterns for front-end data and back-end data, its the same SQL schema in both places. Greatly simplifies the architecture and makes everything feel snappier. It works well when you don't have a social network where users mostly interact with eachother. In the case of Profound, all of your own data can fit in a single sqlite instance and you don't need anything else. You can read more about the syncing philosophy here: https://docs.powersync.com/intro/powersync-philosophy

- Cloudflare Workers + Pages. I have a lot of experience with doing the same type of services in AWS: Lambda + Route 53 + S3 + CloudFront. But Cloudflare made it way easier in terms of DX (and I think they have a much lower-latency network for edge). Another thing that is really cool: you can use javascript-native RPC between cloudflare workers. This made it really easy for the services I deployed to talk to eachother without a whole bunch of fuss. I have a service-oriented architecture and deploy each one independently. Read more here: https://blog.cloudflare.com/javascript-native-rpc/

--- Other Values ---

- Privacy is sacred. This product can't exist at all if people don't trust it. The long-term goal for this is homomorphic encryption. But that's not technically feasible yet with LLMs. So the best we have now is a few basic privacy foundations (no sharing/selling data, humans like employees can't read messages, no using data for ads) and use a privacy-preserving system like Clio (from Anthropic) for analytics.

--- Feedback Welcome ---

You can see the modules that are "coming soon" in the app. Happy to hear any feedback and answer any questions. I built this solo in the last 4 months but hoping to get another couple of folks to help build the next feature set a bit faster. I'm aware of some Android issues for auth and subscription, but fixing those now.

25. Show HN: Pactory – AI Agents Marketplace integrated with Flowise and Langflow

URL: https://pactory.ai/

Author: makosst

Description: We've got to our open beta with Pactory - marketplace for AI agents, that allows to connect an agent from any supported building solution or custom API, distribute and monetize it.

What we've seen for current AI Agent Marketplaces is that they only allow you to monetize an agent built on their solution. This results in most of them being drastically worse than those built on open-source LangChain-based frameworks.

Because of that we don't do any agent building / no-code creation or deployment inside. We allow the users to choose any framework they like, and we integrate with a lot of them to make the process streamlined. Currently we support Flowise, Langflow, Chatbotkit, and have a few new ones coming with official integrations. We also support Custom API that accepts our payload. All covered in our docs: https://docs.pactory.ai/introduction

Our way is that we focus on distribution - availability in search results, social apps (slack, discord etc.), API usage, direct sales from us, and monetization - billing, statistics, payments based on usage with Stripe Connect, we get a 10% cut and that's it.

Would be really happy to hear your thoughts!

26. Show HN: I Built an AI to Auto-Write LinkedIn Posts

URL: https://aposting.com

Author: SamuelWhitehall

Description: Hey HN,

I built an AI that automates LinkedIn content creation—from generating post ideas to writing full posts in seconds.

I started this because I saw how hard it is for people (including myself) to consistently post engaging content on LinkedIn. Whether you’re growing a personal brand, marketing a business, or just trying to stay active, writing good posts takes time.

This AI solves that by: • Generating post ideas instantly • Writing complete posts based on a topic or input • Optimizing for LinkedIn’s algorithm (hooks, CTAs, hashtags, etc.)

Try it here: https://aposting.com

How It Works

1⃣ Enter a topic or let the AI suggest one 2⃣ Choose the tone & style 3⃣ Generate & refine your post 4⃣ Copy & share on LinkedIn

Why I Built This

I wanted to make content creation effortless. I noticed many AI tools generate posts, but they lack customization, scheduling, and engagement optimization.

Would love to hear your thoughts! What features would make this more useful for you?

33. Show HN: AI-Powered Audio Sample Generator (VST/AU)

URL: https://www.text-to-sample.com/

Author: peab

Description: Hi HN! I’m a part-time music producer who got tired of rummaging through sample packs to find just the right sound. I decided to build a plugin that generates audio from text prompts using a diffusion-based model. You can try it in your DAW (VST3/AU) or via a web app. The plugin itself is free to install, but you must pay for any generated audio (credit based at the moment, no subscription required).

Why I Built This
After messing around with generative AI for images, I kept wishing something similar existed for music production. A weekend hack turned into a journey of building a real plugin, dealing with DAW quirks, GPU infrastructure, and figuring out a fair monetization model.

What Makes It Different

• Integrated directly into DAWs: you can drop generated clips right onto your tracks. This allows you to stay in flow state
• Quick iteration: type a prompt, wait a few seconds, and get your WAV.
• Credits-based: $0.01 per second of generated audio.

  Ways to Try It

1. Download the beta plugin on macOS (VST3/AU). Windows support is in progress.
2. Or use the web app (no installation, but you can’t drag directly into a DAW).

   Website (https://text-to-sample.com)

   I’d love to hear your feedback—especially if you produce music or have ideas for how to make AI-generated audio more useful. Feel free to ask questions; I’m around to discuss details of the implementation or to chat about generative AI for music in general. Thanks!

36. Show HN: Font Tester – Test and preview 1500+ Google fonts on any website

URL: https://font-tester.foxcraft.tech

Author: pauls_freeman

Description: Hi all!

I started building Font Tester couple of months ago to help me pick a good font from Google fonts page without having to constantly try them one by one on my website.

Surprisingly a lot of people had similar problem and had taken off, so I continued developing it and added features such as custom fonts upload, kerning, weight adjustments, compare fonts and more to make it easier to test custom fonts.

My journey has been a but bumpy but this is my first product that had performed well, in terms of revenue. I started with an MVP and focused only on developers developing websites without Design files, and got 3 pre-orders for the pro version and once i re-released on product hunt on November it gained more traction and made ~$870 selling lifetime license in the last three months.

Last month (Jan 2025), I found more use cases and decided to talk to type designers, since it could be used to test their fonts or even demo during lettering workshops. Tried to reach out to quite a number of Type designers and finally a great type designer Adam gave it a shot and shared some great feedback, so make sure to check him out as well: https://ladd-design.com/

Also recently, decided to try something different with the landing page, mixed a bit of moder, neo brutalism, and vintage style and changed the copy. Still working on it though.

I would love to hear your suggestions and feedback on Font tester especially if you are a web designer or type designer.

38. Show HN: I Built an API for Electricity Price Forecasts

URL: https://forge-forecasts-frontend.onrender.com/

Author: oceans_r_still

Description: Hey HN!

I built an API that provides day-ahead electricity price forecasts, designed for smart home automation, energy optimization, and data analysis.

Why? With the rise of smart home energy management (e.g., Home Assistant, EV charging, heat pumps, batteries), I wanted a fast, reliable way to predict electricity prices.

What’s working now? Fast API responses – Precomputed forecasts ensure instant results. Reliable daily updates – Automated ingestion of market data. Optimized for efficiency – The /price_forecasts endpoint delivers precomputed data.

Who is this for? Smart home enthusiasts looking to optimize electricity use (Home Assistant, IoT). Developers building energy-related applications. Anyone tracking electricity prices for analysis or automation. Try it out: API & Docs → https://forge-forecasts-api.onrender.com/docs

I’d love to hear your thoughts! What features would make this more useful? Any integrations you'd like to see? Let’s chat!

46. Show HN: Quizzer – Retain More from Podcasts

URL: https://quizzer-f900c.web.app/

Author: jgoldstein46

Description: I built Quizzer to solve a problem I’ve struggled with: we consume a ton of great insights from podcasts, but don’t retain or apply them.

The Problem:

1. Podcasts are passive consumption.

   - Episodes don’t pause for reflection, and most people don’t take notes.  


Even if you hear something valuable, the episode keeps going, and you forget to act.

2. No natural retrieval mechanism.

      - Listeners rarely revisit old episodes.  
   
   
   Without recall & reflection, even the best ideas fade fast.
   
   

3. Application requires intentional effort.

   - Many insights are useful only if acted upon, e.g. protocols for health & fitness

 </code></pre>

The Solution: Quizzer
Quizzer lets you generate short quizzes from podcasts  to reinforce key takeaways. Just drop in a link, and it creates questions to test your recall.
- Turn passive listening into active learning.
- Strengthen retention through self-testing.
Would this be useful for you?
I’m testing whether there’s demand for this kind of tool. Would love your thoughts!
Demo video: https://youtu.be/q53HuXprAbM
Link to my MVP: https://quizzer-f900c.web.app/
I'm also open to feedback on other ideas I’ve thought of to solve the problem:
A podcast app that helps track and apply insights through intentional reminders (e.g., “Did you try cold exposure this week?”), quiz recaps generated for each episode that you can take on-demand, a way to easily view the transcript as you are watching the episode & bookmark insights.
Incorporating spaced-repetition into Quizzer through weekly quizzes that fuse insights from multiple  podcasts you've listened to in the past week and earlier.
