1. Show HN: Offline audiobook from any format with one CLI command
URL: https://github.com/C-Loftus/QuickPiperAudiobook
Author: C-Loftus
Description: QuickPiperAudiobook locally generates an mp3 audiobook on Linux with one easy command. It can convert PDFs, epub, mobi, and many more by using ebook-convert. It uses any piper TTS model, and thus supports a wide variety of languages.
I've had great success using it to read more while reducing eye strain and computer usage. I think I've probably read 30 or so books this way now over the past year. Being able to listen to any content you want in audio form free and offline while going for a walk is extremely handy.
I hope it helps you as well!
Cheers

13. Show HN: Built simple Startup Directory in 3 days – 300 users in 72 hours
URL: https://maze.do/saas-directory
Author: ericssonrd
Description: I was experimenting and asked Gemini AI for an idea inspired by the Million Dollar Homepage but for SaaS and Startups, it suggested creating a startup directory. I thought, “Mmm, what harm can another directory do?" but, I tried to add a unique twist. Make it really simple to submit.
Users can simply upload their icon, short description (I’ve added that later) and web address. The app displays their startup immediately, making it easy for anyone to display their project without hassle.
Posted on Reddit and in just 24 hours, I attracted over 80 users, then over the next couple of days it got to around 300. Now I’ve capped it to 419 and more users keep submitting (submission keep rolling, new ones go to the top and old ones get removed).
I'm glad to share this with the Hacker News community to get some feedback and suggestions for improvement. Some people have suggested monetization options and I’ve tried that but it may not be time for that yet since it didn’t work out.
You can check it here: https://maze.do/saas-directory
Background: This was somewhat of an impulse project comming from my desire to create something useful for Saas Developers. I focused on making it real simple to submit, aiming for a low barrier to entry.
I look forward to your thoughts and any suggestions you might have!

17. Show HN: Pantone Guessing Game
URL: https://pascaltroxler.ch/pantoneguesser.html
Author: trox
Description: Hey HN, I've created a web-based game that challenges you to match Pantone descriptions to its RGB color.
For those who don't know, Pantone provides "a universal language of color that enables color-critical decisions through every stage of the workflow for brands and manufacturers".
These descriptions can be surprisingly subjective and ambiguous (think 'Reflecting Pond' or 'Satellite'). I've created this app to hopefully gain insights into which colors have the largest variance and for you to test your knowledge.

18. Show HN: Slashing LLM Costs for Overnight Batch Inference
URL: #
Author: Blue_Cosma
Description: Hey HN,
If you've tried running open-source models like Llama 3.1 70B or 405B, you might have noticed that it gets very expensive. The reasons look obvious enough that you might have stopped even before trying it!
- GPUs are very expensive to buy or rent
- Running the most performing LLMs need 4, 8 or even 16 top of the line Nvidia GPUs
- And that won’t get you anywhere near the level of VRAM needed to batch enough to get a decent throughput and efficiency
Some have even questioned if open-source LLM providers are not doing some shenanigans to provide the prices they offer. VC funded bait-and-switch? Unclear quantization? Even the most well funded LLM inference startups, with the best inference optimization teams in the world have got into controversy about this.
At EXXA, we wanted to make affordable the best open-source LLMs in all their FP16 glory. And I don’t know for others, but we’re a bootstrapped team of 3, so the subsidizing part isn’t an option :D
I won’t tell you we found the magical solution for all use cases… But we found one for batch overnight jobs! Think things like:
- Synthetic data generation
- Data pre-processing (e.g. contextual retrieval for RAG improvements, knowledge graph creation)
- or LLM-as-a-judge evaluation
Why overnight? Because it gives us time to:
- Get GPU for a high discount (30-90%) as they would otherwise sit idle in cloud providers data centers
- Heavily optimize inference for maximum throughput instead of minimum latency
Today, our batch inference API is live for Llama 3.1 8B & 70B FP16 with output under 24h.
We offer the lowest price per token in the market!
60% cheaper than fireworks, 40% cheaper than deepinfra. Without any hard rate limits and with prompt caching available.
Try it now at https://withexxa.com
------
If you have any specific questions: you can email us at founders@withexxa.com If you want to generate a large amount of tokens with custom LLM models, let us know we can host them and offer the same price ranges as Llama 3.1 8B & 70B. If you want to reduce inference costs for image or video generation, we are actively looking into this with potential users.
What do you think of our approach? Are you willing to wait overnight for super cheap tokens?

20. Show HN: URLs that belong in your sentences
Author: skillseeddev
Description: Hey everyone! I got a quick question for you: which link would you like to put in our announcement post? Is it A. yourwebsite.com/announcement/our-latest-update or B. intr.oduc.ing/our-latest-update
Perhaps it'd be clearer if I put it in a sentence... "Super stoked to finally say that we're intr.oduc.ing/our-Product-Hunt launch!"
See how that link blends in with the sentence? I bet you none of the other URL shorteners can do that - whether it's bit.ly, ow.ly, or dub.co! Impress your X followers by launching with an intr.oduc.ing/your-product link!
This has been an idea of mine for years, and I'm so excited to finally see it in action! I've always hated how obtrusive and unnatural links look in between words, and shortening it doesn't help. This product is a solution to my own problem, and I think it's the same problem that hundreds of businesses are facing as well, albeit a minor one!
Should this replace other URL shorteners like bit.ly? Probably not - it's a different product with different objectives! These might not be the shortest link (and we're not trying to make them shorter), but they flow with your sentence!
I'll continue adding more URLs like this, and this is still a WIP - let me know if there are any features you'd like to see! Cheers!

22. Show HN: Built an alert tool for barber appointments
Author: luukkimbal
Description: It took me 1,5 years to finally launch this tool. It started as a tool for myself because my barber is very busy and I wanted to see when he would get open spots. I have been building on it for way too long and have been procrastinating of when to launch it. It is very easy to use. Users only have to put in their preferences and their email. Users can cancel anytime. It's very specific because at the moment it only works for barbers using the software Salonhub.

23. Show HN: CREV – A Go-based CLI tool for AI code reviews and codebase exports
URL: #
Author: elpookie
Description: I’ve recently built CREV, a Go-based CLI tool designed to get AI-powered code reviews from your terminal. The idea came from my frustration with manually copying code into ChatGPT or Claude to get feedback on my projects. Although ChatGPT could provide me with useful suggestions, it lacked the full context of my project, which often resulted in incomplete reviews since it didn’t know my entire directory structure and the content of all the files. I wanted to fix that, while also eliminating the constant switching between VSCode and my browser.
So after a month of development, I’m excited to share CREV:
- GitHub: https://github.com/vossenwout/crev
- Website: https://crevcli.com/
Features:
- Full Codebase Export: Exports your entire directory structure and the content of all the files of your project into a single text file.
- AI-Powered Code Reviews: CREV reviews your bundled codebase and outputs the review as a markdown file.
- Terminal-Based Workflow: CREV is a CLI tool, removing the need to switch between your editor and the browser.
I have written the CREV CLI tool in Go as I was interested in learning the language and I heard many good things about its efficiency and speed. I used Cobra https://github.com/spf13/cobra to manage the CLI commands and Viper https://github.com/spf13/viper for handling configurations. This is the first project I have done with Go but I find the language interesting and the Go routines also help with reading in your entire codebase. For the code reviews themselves I use google cloud functions which invoke GPT-4o (am also planning to add Claude 3.5 and GPT-o1).
I’d love to hear your feedback—whether it’s ideas for new features or reasons why you believe this tool is useful or useless to you. I am using it daily so it at least solved my own problem :)
