mikerubini··on Show HN: AI Sandbox with Kata, Firecracker, Cloud HV (E2B, Daytona Alternative)
That's the exact use case we're targeting! Once you start giving AI more autonomy in your projects, sandboxing becomes critical. Lots of people are vibe coding in prod these days
mikerubini··on Show HN: AI Sandbox with Kata, Firecracker, Cloud HV (E2B, Daytona Alternative)
Hey HN! Founder here.

Built Cognitora.dev after getting frustrated with existing AI coding environments being either too limited, too heavy or too expensive. We're using Kata containers with the flexibility to run on either Firecracker or Cloud Hypervisor - letting us optimize for the best performance per workload.

Key differentiators from e2b/Daytona:

- True isolation with hardware-level security (not just Docker) - Sub-3s cold starts vs 10-30s elsewhere - Kata flexibility: Firecracker for ultra-fast startup, Cloud HV for heavier workloads - Built-in AI context preservation across sessions - Works with any LLM/model (not locked to specific providers)

The sandbox handles everything from simple scripts to full deployments. We're seeing devs use it for prototyping, code review with AI, and even production debugging in isolated environments.

Still early but would love feedback from the community.

mikerubini··on Show HN: I made AI sales reps for live product demos
Hey, yeah I respect your opinion, of course!

That's why in the beginning of the call it discloses it's an AI. Not all people are cool with it, but for most people who are not into tech, it's actually a fun experience I would argue

mikerubini··on Show HN: I made AI sales reps for live product demos
I built a new software product that does fully automated, live product demos with AI agents. They share their screen and basically replace sales reps demoing the product.

I mainly use Google Meet's API (hosting the meeting), OpenAI GPT v4o (llm), 11labs (for voice), deepgram (for the transcription of the meeting) and Twilio (to connect to the meeting).

Of course, it's early days (I built this yesterday) but so far, the results looks promising.

Unlike pre-recorded demo videos, AI agents can screenshare and demo the product while also responding in real time to questions and handle objections as they arise.

What do you think?

mikerubini··on Show HN: Shadow Top NFT Collectors
Hey HN,

I made a new SaaS over the last 3 days: https://whalepeek.com

You can shadow top NFT collectors and get alerted when they buy, sell or mint a new NFT.

Heavily inspired by eToro commercials that popped up all over Youtube: "copy what top traders do" - Here you can copy what other NFT influencers are doing.

A big problem in doing that has been detecting fake transactions. A lot of scammy creators are airdropping NFTs into influencers' wallet. We detect fake mints, fake buys and fake sales - and only notify you of real ones.

Technically, the project is built in PHP + mysql and some JS for the charts. Hope you like it!

mikerubini··on Show HN: Remote job opportunities from scouring FB
Hey Hacker News,

Yesterday I made https://JobScout.co

It’s a remote job board that takes job opportunities out of Facebook.

Why make yet another remote job board? The market seems saturated at this point.

Here are some considerations on why I decided to make this product a reality:

I feel everybody is either copying Pieter Levels who owns remoteok.com, or using his API. This results in 100s of job boards promoting the same jobs, which then results in more applicants for the employer, but more competition for applicants.

With JobScout, I wanted to exploit a different source, Facebook, in order to get different kinds of jobs, which usually don’t get as much love and that you wouldn’t find on other remote job boards.

Feedback welcome

mikerubini··on Show HN: Search Podcasts by Guest
Hey Hacker News,

Problem: I often hear someone on one podcast and want more, but there's not an easy way to find them elsewhere.

Until now.

Podda allows you to search podcasts by guest, and also receive a notification whenever a person you like gets on a new podcast.

I just coded this today in ~5 hours, and all feedback is welcome.

Question: right now I only list episodes a guest appeared on. Should I also list podcasts that a guest hosts?

mikerubini··on Show HN: Search fast-growing Facebook groups
Hey, I made this quick tool that allows you to find interesting Facebook groups. Insert a keyword to search, filter, sort, and export results in plain text and CSV formats.

You can also scan groups to quickly analyze how fast they are growing, and how engaged the community is.

Here is a list of Fb groups that are growing fast: https://targetsnake.com/top-groups

It's totally free and I'm sure buggy (I made this in 12 hours), but hopefully useful!

Best, Mike

mikerubini··on Show HN: I made a list of keywords you can rank for in the Shopify app store
Ever wondered what are all the keywords you can rank for in the Shopify app store?

I just shipped a new project for Shopify developers. It's a list of keywords you can rank for in the Shopify app store.

It's also useful to discover low-competition keywords by checking the average rating and number of reviews on the first page of results for each keyword.

Completely free.

mikerubini··on Show HN: My course on data collection (scraping)
Hey hacker news,

I've built my career and 10s of software products based on a simple idea: collecting third-party data for profit.

I'm now teaching others the few things I know about it. LMK if you'd like early access.

Thanks, Mike

mikerubini··on Show HN: Free tool to get more targeting interests out of Facebook
Hey Hacker News,

I built this tool around uncovering Facebook advertising interests.

For each keyword you put in the ads manager, Facebook™ shows only 25 interest suggestions, the same that it shows to everybody.

Turns out more interests are just an API call away. If you are a dev, it's pretty simple but I thought to develop a free tool for non-technical people.

This was a small feature of a product I built almost three years ago and decided to give it new life.

It's entirely free to use.

Hope you like it!

mikerubini··on Trends by MKBHD
I spent the morning analyzing 100s of tweets and videos from one of my fav tech youtubers, MKBHD, and compiled a list of trends he spotted in tech.

Besides folding phones and rotating TVs, he was sure USB-C was going to be a thing already in Dec 2016

Here are all the trends ↪ https://treendly.com/spotters/mkbhd

mikerubini··on Show HN: I made a Chrome extension to visualize trends inside Google search
Hey HN,

I've been working on a Chrome extension to visualize trends right inside Google search.

It's pretty simple: a trend chart is added for each term that you search so you can see at a glance if it's trendy or not.

You can check if the term is trendy in different countries.

In addition, you can check more details on the trend by going to our main site.

It's a beta but it works, so all feedback is welcome! Thanks, Mike

mikerubini··on How to spot trends early using Google (free course)
Thanks and sure, let me know what you think!
mikerubini··on How to spot trends early using Google (free course)
Hey, I just launched a new course on how to spot trends. It's free if you create a free account on the platform.

In the course you will learn useful Google tools to spot trends as well as how to piggyback on the existing demand created by a trend.

I was too cheap to buy a platform to host the course on (Podia, Kajabi, etc..), so I built one myself where users can mark lessons as completed, and comment (through disqus).

Full disclosure: I own a startup in the space (Treendly). That means that I eat and sleep trends, so I think you will learn a thing or two, hopefully.

Enjoy!

mikerubini··on I earned over 100k$ as a SaaS solo-founder. I did it to protect my music
My name is Mike and I’m a software entrepreneur from Italy.

I earned over 100,000€ over the years as a SaaS solo-founder and bootstrapper.

I'm not rich at all, but I'm doing this for another reason: protecting my music.

You see, I’m a jazz musician and I like to play. But, being a musician is hard and if you want to earn a living by playing music, you most likely have to compromise on your art.

This can mean playing weddings, doing gigs you don’t want to, or teaching kids who are not interested in music at all, and while those are things that are absolutely fine for others, I just don’t like them.

Now I can make time to play when I want and to help my family when they most need my help.

I hope my journey can inspire you! Mike

mikerubini··on Show HN: I built a service to uncover hidden Facebook advertising interests
Hey there, thanks for commenting!

If you don't use Facebook, probably you are not familiar with the Facebook ad manager.

It's a tool for advertisers on Facebook.

For each keyword you want to target, the Facebook™ Ads Manager shows the only 25 interest suggestions, the same that it shows to everybody.

We don't. We show you a lot more so that you can target interests that your competition is not.

Hope this clarifies it!
