1. Show HN: API Parrot – Automatically Reverse Engineer HTTP APIs
Author: pvarghav
Description: When automating business processes at work, I found it difficult and time-consuming to reverse engineer business systems' APIs. I often had to manually reverse engineer APIs using developer tools or settle for less optimal technologies such as Robotic Process Automation (RPA).
Often, the issue is that it can be hard to resolve all the cookies, access tokens, and other elements required to successfully execute the requests. Manually trying to resolve these dependencies using developer tools is especially challenging with multiple requests where data is stored in JavaScript objects or HTML elements.
To try to solve this issue, I built a tool called API Parrot that automatically identifies the data correlations between requests and builds a graphical representation of the flow to give users a better understanding. To streamline the process, I also included functionality to record requests, define your own inputs and outputs, and export the entire flow—or parts of it—as JavaScript code.
The application is Electron-based and currently compiled for Windows and Linux. Please try it out and give feedback!

6. Show HN: Launch a static website in under 30 seconds
URL: https://orbiter.host
Author: jhunter1016
Description: Happy New Year HN!
I’m the co-creator of Orbiter, a dead simple tool for uploading and hosting static sites. We built Orbiter for ourselves and realized it would probably be useful for others.
Static site content is some of the simplest on the web, yet hosting this content has gotten increasingly complex over time. Many of you are engineers and don’t have much problem with CI/CD pipelines as a mechanism for deploying a website. This is true for me as well. But there are times when I want to just upload a simple website. I might not even want to put it under source control. And I know this is true for a lot of others who don’t have the same level of coding and deployment experience as I do.
Combine this with AI’s rise in popularity and how easy it is now for anyone in the world to create a website, and Orbiter seems like a nice solution to getting static websites online.
On the technical side, we did something interesting. We actually use blockchain and IPFS behind the scenes. Having worked with IPFS for a number of years now, it’s always struck me as a really good tool for public content, especially when that content needs to be versioned. Websites fit this model nicely.
We wanted to create a system by which websites were not necessarily locked into Orbiter’s platform. So, every site that is uploaded gets its own smart contract on the Base blockchain. The site itself is uploaded to IPFS, and the CID is mapped to the site’s smart contract. When someone makes a change to their site and uploads new content, the new CID is mapped to the contract.
This does two things:
1. It allows anyone in the world to build a version history of the site 2. It allows the site’s creator to easily migrate off Orbiter without even having to access the Orbiter web app if they want
Ultimately, people may not care about the blockchain and IPFS aspects of the technology, and that’s fine. We specifically built it so that you didn’t even see this tech.
Would love to get feedback on the product, the idea, and the technology!

7. Show HN: I built a green noise player to help you relax, focus, and stay calm
URL: https://www.noisygreen.com/
Author: nyku
Description: Sometimes, I struggle to block distractions and create a calming environment while working.
Most tools I’ve tried were either cluttered, didn’t provide the right kind of sound, or required payment.
So, I decided to build my own simple green noise player.
For context, green noise features balanced, mid-range frequencies that mimic soothing natural sounds—ideal for relaxation, focus, or creating a peaceful backdrop while working.
It’s also great for taking a mindful break during a busy day.
Right now, it’s a free, lightweight, browser-based solution.
Playback pauses on mobile when the screen locks, but I’m exploring ways to improve it. Maybe a dedicated mobile version in the future?
Would love to hear your thoughts and feedback!

8. Show HN: Computesim, learn compute shaders and control flow
URL: https://github.com/planetis-m/compute-sim
Author: planetis
Description: Hey HN, I wrote a compute shader emulator that started as a 50-line script to help me understand reduction shaders. What makes this implementation interesting is its technical approach; I've leveraged Nim's macros and closure iterators to simulate lockstep execution of logical threads. The emulator runs GPU compute shaders on CPU, simulating workgroups and subgroups with proper synchronization. It supports GLSL subgroup operations and provides nice debugging messages. The emulator works with Nim code that follows compute shader patterns
I've documented some technical aspects here: https://x.com/planetis_m/status/1873857578931011614 Demo/Repo: https://github.com/planetis-m/compute-sim

14. Show HN: Startups and Survival: Silicon Valley's Squid Game"
URL: #
Author: throwunderfog
Description: Joining a Silicon Valley Startup Is Like Playing Squid Game
---
Scene: A hopeful coder, Alex, walks into the chic, glass-walled office of "Unicornify," a startup promising to "revolutionize sandwich personalization with AI." The team is gathered in a minimalist conference room. Everyone is wearing branded hoodies and looks suspiciously sleep-deprived.
Alex: "Thanks for having me. I’m excited to join Unicornify!"
CEO (with a perfect white smile): "Welcome! Remember, here at Unicornify, we’re a family. A family that plays to win."
The lights dim. A disembodied voice echoes through the room.
Voice: "Attention all employees. The first game is Ping Pong Deathmatch."
Alex: "Wait, what?"
Two employees are dragged to a ping pong table. A robotic arm serves the ball at 200 mph.
Employee 1 (sweating profusely): "I have three kids, man. Let me win!"
Employee 2: "My stock options are vesting next week. Sorry, bro."
The match begins. Employee 1 loses. A trapdoor opens beneath him.
Alex (whispering): "Where did he go?"
HR Manager (nonchalantly): "He’s pivoting to new opportunities."
---
Scene 2: Alex’s first day. The "work hard, play hard" mantra is taken literally.
Manager: "Our KPI this quarter is scaling user engagement by 3000%. Here’s your desk, your laptop, and your weight in energy drinks. Oh, and remember, no one survives past Series B without hustle."
Alex notices an ominous poster on the wall: "ONLY 10 WILL MAKE IT TO IPO."
---
Scene 3: The All-Hands Meeting.
CEO: "Today's challenge: We’ve run out of funding. Your task is to find a way to keep the servers running without money. Losers... well, we all know what happens to losers."
Alex: "This feels intense. What about work-life balance?"
The room erupts in laughter.
Coworker (whispering): "Work-life balance? That’s for the Series C startups. If you survive this round, maybe you’ll get free kombucha."
---
Final Scene: Alex has somehow survived weeks of sprints, sleep deprivation, and competitive foosball. The final test arrives: The Pitch Gauntlet. Alex faces off against the CEO in a game of "innovate or die."
CEO: "Pitch me the next big idea or... you’re out."
Alex (panicking): "Uh... AI-powered sandwiches that... predict your emotional state?"
CEO: "...Brilliant. You’ve earned another quarter. Congratulations!"
Confetti falls. Somewhere in the background, an employee screams, "WHAT ABOUT MY VACATION DAYS?"
Alex (to self): "I made it. But at what cost?"
---
End scene.
Moral of the story: At a Silicon Valley startup, you're not just playing the game; you are the game.

16. Show HN: MailMock – Simplified Email Testing for Developers
Author: daneavanderbilt
Description: I work at a software consulting company where we often face the challenge of testing email functionality in non-production environments. Typically, email sending is disabled in development and staging, making it difficult to verify whether emails are formatted correctly or even sent at all without making significant code changes.
I experimented with self-hosting an SMTP server, but the maintenance overhead was too high. This led to the idea for MailMock, which offers a simpler solution: by simply changing the SMTP credentials, you can redirect emails without the need for server management or code rewrites.
MailMock is a tool designed for developers to test emails in development and staging environments. It captures emails into dedicated test inboxes, allowing you to validate your app's or website's email flow. Features include multi-user collaboration and an email retention policy of up to 90 days, making debugging and testing easier. On the technical side, MailMock is built using C# for the backend, React for the frontend, and SQLite as the database.
You can try MailMock by signing up [here](https://mailmock.dev/sign-up). Once you sign up, you can create a project and immediately start testing by changing your SMTP settings to point to our service.

Description: Hey everyone! As a New Year holiday project, I built out a MacOS tool that constantly measures typing speed and accuracy in the background and displays it on the status bar.
I always used to wonder if my real-life typing speed is similar to how I perform during typing tests on typeracer etc. I looked for tools like this, but could not find anything out there. So, I gave myself a gift this new year by actually creating this app (it only took 2 days - thanks to AI and no thanks to Apple’s poor developer documentation).
It would be great if you could try it out and let me know what you think.

20. Show HN: Sama Deploy One-Click Docker Deployments on Hetzner with Automatic SSL
Author: JangoCG
Description: Hi HN!
I'm the founder of Samadeploy.com. In the last year, I launched multiple side projects and kept facing the same challenge: repeatedly setting up VPS servers on Hetzner from scratch. Each time, I had to look up my bookmarks and configs, which significantly slowed down my process. That's why I built Sama Deploy - an intuitive app with which you can:
- Instantly provision Hetzner servers
- Deploy any containerized app with a single click
- Get SSL certificates automatically
- Protect your sites from the public by easily adding basic auth
- Edit the Docker Compose file directly in your browser
Under the hood, I built on top of Docker and Caddy. So if you ever want to do something which you cannot yet do with my app, you could always just SSH into your server and adjust it yourself.
I built this solution to solve my own deployment headaches, and now I'm making it available to other developers. Sama Deploy is offered as a one-time purchase - just run a single command to install it on your own server.
What do you guys think? I appreciate any feedback. Happy new year and greeting from Germany

URL: https://www.learnlingo.dev/
Author: ct271
Description: Hey HN! I'm Callum, and I'm working on a way to make learning new languages easier using AI.
Personally, when I've been learning a new language, I've always found it hard to find someone to practice with. To overcome this, I started playing around with AI to see if they could make the process easier, and found that it was fun and simple to converse with them, and that I was learning new vocab in the process. So, I decided to make a simple product out of this that added some convenience to the process.
LearnLingo lets you practice the language that you're learning with a number of different AI tutors, each designed to help you practice a particular part of the language (eg: movies, classical music, food, etc). It operates on a token based system, so there are no subscriptions (I personally hate subscriptions).
Have a try, and let me know what you think! I'm open to any feedback, feature suggestions, or constructive criticism!

Author: larryboyko
Description: (I solicited feedback from this wonderful community for a draft of this project eight months ago: https://news.ycombinator.com/item?id=39972586 ... I was humbled by and am wholeheartedly grateful to several brilliant proofreaders; their names appear at the end of the second chapter.)
Dimity Jones In Puzzle Castle: An Electronic Escape Novel in Eighty-Nine Ciphertexts is a (mostly) fictional story, contained in a single text file, that requires the reader to solve puzzles as they go along, and to use each chapter's solution as a key to decipher the next.
Think: escape room in the form of a novel -- or, as one reader put it, "Interactive Fiction meets Advent of Code."
A computer, and rudimentary coding skills in a language of your choice, will be indispensable for performing the transformations -- and might help with the solving too!
My wife, the author, passed away six years ago. This is not the last thing she wrote, but it is the most unusual, unapproachable, and personal of her major works. It is also, as the only novel of hers that I cannot breeze through in an afternoon (and despite my unflattering appearance in it), my favorite.
Though Dimity Jones was left unfinished, and perhaps abandoned, at the time of my wife's death, its elements were all there, on her hard disk, awaiting only a final compiling. My contribution to this text has therefore been little more than that of an occasional copyeditor (my wife was a meticulous speller and self-proofreader) and playtester.
Thank you for checking it out.

Author: ngsayjoe
Description: After 4 months of development, I'm humbled to share my no-code tool called Otak that simplifies WhatsApp chatbot creation without the need for coding or complex flowcharts.
Why did I build this?
Integrating with the WhatsApp Cloud API is notoriously challenging, even for experienced developers. For small businesses and non-technical users, it's often impossible. Despite the many chatbot solutions available, most were built pre-ChatGPT, relying on outdated flow-based approaches rather than RAG. For those that were built post-ChatGPT, WhatsApp integration is often not a priority.

30. Show HN: Built a tool to integrate OpenAI, Claude and Gemini in few hours
URL: https://plugai.io
Author: riddhesh24
Description: I work 9-5 as a software developer and also take on some freelancing projects.
I observed that all clients face some common issues when integrating AI into their applications.
I have received many project requests that start with multiple AI models because clients want to see which AI models generate the highest quality output. However, once they understand that adding more AI models will take more time and money, almost every one of them narrows the options down to just one AI model.
Initially, I also suggested to clients to use the UI provided by each AI model provider. However, the actual output differs when developers implement it, because developers always ask AI to return JSON, which results in inconsistent outputs.
Also, the same prompt does not work for every AI model. For example, if your prompt works with OpenAI, it may generate a different output in Gemini. If not handled correctly, this could even crash your website. Every time this happens, I have to ask the client to provide an updated prompt for that specific AI model, and once again, I need some time to code it.
Because of all these issues, I thought, why not to build a product that implements everything I've learned over time.
That's how I built plugai.io. You will get a dashboard and a public API. From the dashboard, you can configure input/output schemas and prompts, and you can trigger those prompts using the public API. This way, your developers won't have to deal with prompts, they will only need to make an API call to PlugAI, and everything else can be configured using our dashboard. Currently, I have added 12+ AI models from OpenAI, Claude, and Gemini. You can also add multiple variants for the same prompt, and each variant will be triggered for a specified AI model.

36. Show HN: PVBenchmark – Forecast and Benchmark PV Systems with Real-World Data
Author: muc-martin
Description: Hi HN,
I want to share PVBenchmark with you, a side project designed to help owners of photovoltaic systems forecast and benchmark their solar energy production.
Small plug-and-play solar systems, like those increasingly popular in Germany and around the world, allow homeowners and renters to install solar panels on balconies, rooftops, or backyards. These systems make renewable energy more accessible and help reduce electricity bills. However, understanding how well a system is performing or whether it’s optimized can be challenging.
PVBenchmark is here to address that challenge by offering:
Forecasting: Enter your location and details for multiple surfaces (orientation, tilt, and capacity) to get tailored solar production forecasts.
Benchmarking: Compare your actual energy production with real-world data from other users’ systems. By crowdsourcing production data, the platform builds a growing dataset that enables meaningful comparisons and insights. Over time, the plan is to expand benchmarks to include specific solar modules, inverters, and batteries, providing unbiased evaluation data beyond product marketing claims.
Though the project started with a focus on Germany, PVBenchmark now supports English and supports global production forecasts. As interest in small-scale solar systems grows in the U.S. and beyond, I hope this platform can become a valuable resource for homeowners, renters, and energy enthusiasts alike.
It’s an early version, and I’d love to hear your feedback. Thanks, and I look forward to your thoughts!

37. Show HN: Hockey Roster Generator with AI
URL: https://roster-gen.vercel.app
Author: PhillyPhuture
Description: So, I am not a software engineer but I do like some Excel, PowerQuery and VBA.
Seeing all the amazing work that Claude can do, I spent the last 5 days (until 8:30am) building a web app pretty much only with Claude, Vercel, Visual Studio, NeonDB (marketplace).
I know this is a simple app and I know I have not "hardened" this, but I cannot tell you how empowering this was and how much more I want to build.

39. Show HN: I made a daily word puzzle, Collections
Author: usefulcat
Description: Each day there are three hidden words. You have to figure out the category the three words belong to whilst spending as few of your 100 points as possible.
Spend points to reveal all instances of a given letter - different letters have different point values. Guess the collection when you can but guess wrong and it will cost you 5 points.
I've built it so you can create your own Collections puzzles too which you can share with your friends
Technical stuff:
- Written in Blazor server side with Bulma and SQL Server
- FuzzySharp for fuzzy logic to handle spelling mistakes, typos and suchlike in the answers

41. Show HN: I created a SEO machine for Next.js
Author: Ad_stefnum
Description: SEO is the longer-term marketing strategy.
O.G indiehackers like Danny Postmaa have proved this.
We all hate doing marketing though, if you're an indie hacker like me.
You have to optimize all pages in your app but that is soooo little if you don't have a blog.
You need a blog.
I had a little laziness in putting up a blog that I liked. I didn't want any of that markdown rubbish because it was too hard to edit on the go. I also didn't want stuff like strapi where you had to pay a monthly fee
If you use Nextjs, you never have to build a blog if you don't want to. I built a solution so you just:
- Download a couple of files
- Follow setup instructions
- Publish a post and you have your blog live

42. Show HN: Counting Tap Toy
URL: https://memalign.github.io/m/counting/index.html
Author: memalign
Description: Hi HN! This is a project I made for my 3-year-old who always skips “14” when counting.
In Counting Tap Toy, you can tap to count various aquatic creatures. The count is displayed and announced. My hope is that seeing and hearing the numbers will reinforce 14’s existence.
I find tapping all the fish while listening to the songs and popping sound effects to be pretty relaxing too.
Technical details: https://memalign.github.io/p/counting.html
This is the fourth “Tap Toy”, joining:
