3. Show HN: I built a post filtering Safari extension for Reddit to replace RES
Author: edgarischatting
Description: After Reddit Enhancement Suite (RES) became unmaintained, Safari users on macOS lost access to post filtering capabilities. As a developer who switched to Safari, I missed this functionality and decided to build a solution.
What it is: A Safari extension that filters Reddit posts based on keywords and wildcards. It monitors the DOM in real-time and hides posts matching your filters, working on both old and new Reddit interfaces.
Technical implementation:
- MutationObserver for DOM monitoring
- Batch processing
- Client-side filtering with zero external dependencies
- Wildcard pattern matching (e.g., “politic*” matches “politics”, “political”)
- JSON-based filter import/export
- Local storage for settings persistence
Key architectural decisions:
- Chose MutationObserver over polling for efficiency
- Implemented batch processing to handle Reddit’s infinite scroll without impacting performance
- Abstracted DOM selectors to support both Reddit interfaces
- Used CSS modules for style isolation
- Kept the codebase minimal and focused on the core filtering functionality
Try it out: Available on the Mac App Store. Currently running a 25% off Black Friday sale.
Looking for feedback for feature ideas or bug reports. I also have 5 TestFlight invites if anyone is interested in beta testing.

Author: Cheruii586
Description: Hi,
My name is Kevin, I’m a solo indie developer at Lilucat, where I handle everything on my own, from design to the final product. Despite this, I always strive to prioritize the user experience and put users first, no matter what.
I’d like to share my latest project with you, “Storage Cleaner”, which I’ve been working on for the past five months. I’m really proud of the results, and early user reviews indicate that people are enjoying the app. To celebrate the release, I’m offering a Free Forever deal for early users, with a free lifetime offer available until December 6th.
As the name suggests, Storage Cleaner helps users clean unnecessary photos, videos, and files from their phones. What sets my app apart from others on the App Store is its unique ability to clean social media clutter, something I haven’t seen offered anywhere else.
I’d love for you to give my app a try and take advantage of the Free Forever offer.

URL: https://www.moodsongs.net
Author: shivam_nextjs
Description: Hello,
This is Shivam
I built AI-Generated playlist platform that picks the perfect music based on your mood. It uses machine learning to understand your emotions and fetches the best music videos from YouTube using Youtube API. The platform creates custom playlists for different moods, like happy, relaxed, or motivated, and adapts as your mood changes. I wanted to make sure the music always matches how you’re feeling, so I added a recommendation system that learns from your preferences and keeps getting better over time.

13. Show HN: Twitch plays Codebuff – a natural language coding experiment
URL: https://www.twitch.tv/codebuff_ai
Author: brandonchen
Description: Hi HN! We launched Codebuff last week, and it gave us a fun idea to try: Twitch plays Codebuff.
We rigged up Twitch chat to control an old laptop of ours by sending Codebuff commands. Any chat message prefixed with ‘>’ is interpreted as a command for Codebuff. We’re starting with a blank web app running on localhost. So if you say “> Make the header spin”, then Codebuff will modify the css to make it happen. Codebuff can also run any terminal command (I hope you don’t brick our laptop haha).
Yesterday we tested this out with our community and they successfully got Codebuff to add a map of the US (via installing some package that it found), add all the state capitals as red dots, and draw the shortest path through the capitals. They also built a little synthesizer together.
Maybe this could create a new category of open source, where a bunch of people synchronously create whole apps together by guiding an AI with natural language input? It’s exciting to combine the creativity of a crowd of humans with the raw ability of a coding agent. It’s also just fun to create with strangers and take an app in wildly different directions!
We’ll be here for a couple hours, feel free to pop on by and add some fun stuff to our website! Or maybe troll everyone, iono.

16. Show HN: Soshials – launch your social media platform and get real user feedback
URL: https://soshials.com
Author: swizzle36
Description: When launching my own niche social media platform, I realized that the hardest part was getting the first few legitimate users on the platform who could give real feedback. To make things worse, sites like ProductHunt and the many other SaaS directories don’t really cater to social networks, nor do they facilitate people actually trying the products/platforms over a longer period of time. It’s mostly just other founders.
That’s why I created Soshials. We’re a community of people passionate about niche social networks. We think they’re vital to the health of the internet and important to preserve and build up in the age of a few large players.
The way it works is simple. If you’ve built a social media platform or simply know of an interesting one, submit it to Soshials. Interested people then sign up to join a “cohort” where they can try it with other people in the cohort for a month. At the end of the month, we collect and organize feedback from all users.
It’s completely free and meant to be a fun and new way to help smaller social networks grow and get feedback from early users.
Hope people find it useful. If you know of any niche social networks, do let me know!

17. Show HN: BookRead – AI Integrated eBook-Reader App
URL: https://apps.apple.com/ca/app/bookread-ai/id6737578649
Author: frankt002
Description: Few months ago I was reading “The Genealogy of Morals” by Friedrich Nietzsche, but it was so difficult that I had to take pictures of each page, ask ChatGPT for explanations so that I can understand it.
So I decided to build BookRead.
BookRead is an AI-powered e-book reader that make reading effortless, and help get more out of every book.
Instead of traditional “look-up” or “dictionary”, BookRead uses AI explanations to clarify everything—from individual words to entire paragraphs—within the context of the book.
Other AI features include:
- AI reminders of your previous readings in case you forget.
- Automatically generated flashcards at the end of each chapter to help you retain key ideas.
This is most helpful for people reading classic novels, philosophy, history or religious text.
Love to hear your feedbacks on this!

20. Show HN: Libretto – Simple recording and editing, an alternative to Descript
URL: https://libretto.fm
Author: michael_y
Description: Hi HN, We’re excited to share Libretto – a web-based recording and editing tool designed for creators, podcasters, and teams working remotely. If you’re familiar with Descript, you’ll find Libretto is similar but with unique features and a focus on simplicity.
What makes Libretto unique:
Local recording for high-quality audio/video: Libretto records media locally on each participant’s device and uploads it in the background, ensuring pristine quality even under poor network conditions. This works like double-ended recording but entirely within your browser.
Powerful yet simple editing tools: Transcript-based editing: Edit audio/video as if you’re editing text. Automatic filler word removal: Get rid of “uhs” and “ums” with one click. Core editing tools like splitting, trimming, and cropping are intuitive for non-professionals.
Collaborative and browser-based: No downloads required – everything runs in the browser. Teams can work together, sharing projects and edits in real time.
Built with:
LiveKit for webRTC infrastructure, Deepgram for transcriptions, Rendley’s video editing SDK and Liveblocks for real time shared state.
Libretto is free to try, and we’d love your feedback to make it better. If you’re curious, check it out. Questions, thoughts, or suggestions? We’re here to listen!

Description: Chrome Stealer is a tool designed to decrypt locally saved passwords on Windows machines. It was developed because existing write-ups and C/C++ versions were either ineffective or unsatisfactory. I hope this write-up assists others who were in a similar situation.
If you’re interested in the full implementation details and reasoning behind the project, I’ve also written a detailed blog post: https://bernking.xyz/2024/chrome-stealer/.

23. Show HN: PerfAgents – Find Issues Before Your Users Do with Synthetic Monitoring
URL: https://www.perfagents.com/
Author: ajith-joseph
Description: Hello HN! We’re excited to share PerfAgents, a synthetic monitoring tool built for startups and enterprises seeking robust and proactive monitoring across global regions.
TL;DR:
PerfAgents is a synthetic monitoring platform that uses your existing E2E automation scripts (Playwright, Puppeteer, Cypress, and Selenium) for web app monitoring, reducing setup time by 80%. No complex integrations, no vendor lock-in, and proactive alerts that let you catch bugs before users do.
Problem We’re Solving:
Ensuring application reliability across all regions is tough, especially when existing monitoring tools either require extensive DevOps/QA setup or lock users into proprietary workflows. This results in inefficient workflows, delayed issue detection, and, often, user-facing bugs in production environments.
How We Solved It:
PerfAgents offers a multi-framework approach that lets you monitor app functionality without needing new integrations or script re-recording. By reusing existing end-to-end scripts, PerfAgents makes setup fast, keeps monitoring flexible, and allows teams to detect and resolve issues faster.
Features include:
-> Multi-framework support for Playwright, Puppeteer, Cypress, and Selenium
-> AI-driven monitoring script generation to automate monitoring setups with no code
-> Global test execution for instant insights across regions
-> Real-time alerts integrated with popular tools (Slack, PagerDuty, Jira)
-> Flexible pricing based on execution frequency, not script complexity
How It Works:
-> Setup: Connect your GitHub repository to import existing scripts, or use our built-in AI tools for zero-code setups.
-> Monitor & Alert: Configure regional monitoring and alert channels, with real-time notifications when an issue occurs.
-> Optimize & Scale: Review logs, performance reports, and leverage our multi-framework support to refine application flow monitoring.
Key Benefits:
-> Faster issue resolution: Early detection and instant alerts prevent downtime and improve stability.
-> Cross-team collaboration: Centralized data helps DevOps, QA, and product teams collaborate more effectively.
-> Flexible framework support: Avoid vendor lock-in with multi-framework compatibility.
-> High scalability: Configurable monitoring counts ensure you’re only paying for what you use.
PerfAgents is already in use by Fortune 500 companies and has helped SaaS and e-commerce teams reduce downtime by 40% and cut support tickets by nearly 57%.
Who It’s For:
-> DevOps, QA, and Engineering leaders looking to optimize monitoring setup and execution
-> Teams already using frameworks like Playwright, Puppeteer, Cypress, or Selenium
-> SaaS and e-commerce platforms where reliable, global user flows are critical
PerfAgents is available for a free trial now. We’d love to hear your thoughts, and if you have any questions, feel free to ask!

URL: https://stalwart-entremet-08eb9c.netlify.app/
Author: azzen
Description: Hey everyone,
I have been recently experimenting with video content as part of a Video challenge.
I have ADHD One of the things I struggle with is memorizing scripts when recording videos.
Free apps didn’t help much. I didn’t wanna pay just to get the teleprompter feature so I took matters in my own hands and built an online recording studio with Ai.
My tech stack is: Vite, react and bolt.new
I can script, record, download my video from one place.
And the best thing? I don’t need worry about file storage fees.
All feedback is welcome. Thanks!

28. Show HN: Hacker News Summarizer with Gemini Nano
URL: https://github.com/hydroweaver/hnsummarext
Author: hydroweaver87
Description: Hi All!
For Google Chrome Built-in AI Challenge (https://developer.chrome.com/blog/ai-challenge), I tried to create a simple hacker news post summarizer. It essentially sends the bulk of a top comment and its child comments to the local summarizer to get a summary.
The idea was to see how local models work and the kind of latency they offer. The extension in it’s current form is fairly rudimentary and works only for hacker news. Plus the latency to fetch the summary is noticeable.
I understand, a general-purpose summarizer would kill the need for such a thing, but I built it for getting familiarized with chrome extensions as well as Gemini Nano APIs.
I’m curious to know if there is any value in such an extension and of course any other thoughts / comments / feedback.

30. Show HN: Akka 3 – platform to build and run responsive apps
URL: https://akka.io
Author: TylerJewell
Description: Akka was originally launched in 2009 by Jonas Boner from Sweden as a toolkit to make it simpler to program concurrent apps on multi-core systems. It grew over the years into a set of libraries for building distributed systems with persistence, clustering, integration, and protocol extensions.
Akka has been downloaded more than 1 billion times and powers 100,000 apps. Many of the apps that you use every day have Akka under the covers.
Akka was known for two things - always worked, and incredibly steep learning curve.
We’ve been working on a reinvention of Akka for the last 8 years and it’s released today - Akka 3. It is an evolution of the libraries into a platform for building and running responsive apps.
It contains a new, simple SDK. Most programmers, regardless of their language of expertise, will be productive in under a day building real time, streaming, durable systems. The SDK includes offline development, test kit, separation of concerns, and a variety of components for building distributed systems: entities, workflows, views, streams, timers, actions.
It also includes a set of Serverless and other cloud operating environments.
Beyond being simple to build, the system now contains multi-cloud application deployment. Write a stateful application once, and it will be read-replicated or write-replicated across many regions, many of which operate across different hyperscalers. You can use the location transparency of Akka to move apps, which enables migrations and repatriation in addition to new forms of failover and disaster recovery.
We are providing 500 hours of free hosting with new accounts. Learn more at Akka.io.

Author: alexandroo
Description: When planning your whole life in order to see your Tasks in Perspective (PerspecTask), it’s important to know that only you have access to your private thoughts. No employee of the app can see your goals because they are encrypted before they are sent to the server.
A goal can have unlimited subgoals and unlimited “parent” goals, which is something I wanted for a long time because you can see how a completed task gets you closer to achieve multiple bigger goals.
I hope it helps you achieve your highest life goals!

Description: The classic Bleach vs Naruto fighting game has been around for over a decade, and with its recent 3.3 release, there’s renewed interest in the community. While the game has always been browser-based, finding a reliable place to play has been challenging.
I built a minimal landing page as a stable entry point for both new and returning players. The project includes:
Clean interface to play directly in browser. Clear documentation. Latest version 3.3. GitHub repo [https://github.com/SmileyEmily/bleachvsnaruto] for community contributions. I’ll also be hosting gameplay sessions on Twitch [https://m.twitch.tv/smileyemilyj] to build the community.

42. Show HN: OnAir – create link, receive calls
URL: https://onair.io/
Author: bigmicro
Description: Hello HN community,
This is bootstrapped/indie hacker-ish. Would appreciate feedback.
What it is: You create a link (e.g. onair/yourname), and anyone can call you from it. Caller uses a web browser to make the call (not dedicated app). You can create as many links as you want, and can direct calls to colleagues in a round-robin or escalation manner.
In a way, it’s like the “opposite of Calendly”; whereas Calendly is about meetings in the future, OnAir is about immediate meetings.
Motivation behind it: One of our SaaS products was struggling to grow. We believed that if we provide more “hand holding” to visitors on the landing page, it will increase conversion. It’s like speaking to the guy behind the counter before making a purchase. That idea/experiment, over time, became OnAir.
Feedback: Identifying the perfect use case / customer has not been easy. E-Commerce store owners, which I thought would be ideal customer profile, are not responding as expected (e.g. “why use this instead of a WhatsApp button?”). The value of branded links, round-robin, recording/transcription, lead capture, etc does not seem to matter much to them. Ideas are welcome.

43. Show HN: I made a Piglet’s Big Game website where you can play online
URL: https://pigletsbiggame.net/
Author: yangxiaobo
Description: Hey HN,
Piglet’s Big Game unexpectedly surged in popularity on social media platforms, particularly Twitter.
The sudden spike in popularity has led to a scarcity of physical copies across various platforms, with prices soaring on resale sites like eBay—some listings now exceed $70 compared to previous prices around $20-$30. And it is out of stock on most platforms.
This has led to many people wanting to experience it but having nowhere to play it. I found a version that can be played online and put it on the website, where you can experience it directly online. I hope that those who want to play can experience it.
ps: This online version is still very different from the original version, and the picture quality is not very clear, it is only for experience.
would love your feedback pls
