Hey everyone, I hope you are well.

I built a platform for builders who built vibecoded sites/businesses/apps/start ups etc, who just want to build and not worry about markets, competitor analysis, pitch decks, business plans etc. You pop your URLs, code, files, images, chatgpt, Claude, Gemini chats etc in and it generates it all for you. You pivot, change prices, markets, it changes it all for you as a living document and workspace and export it in any format you want.

This idea stemmed from my own frustrations of building a healthcare startup as a tool for myself but spiralled into something else.

It's early stages and looking for some potential testers if possible who will get free access to help me improve it and hopefully help you too.

$1,437 net profit on 5 hours of actual work this week, 10 items sold, all of them found by the free bot I built and open-sourced a few months back.

Quick context on me, I'm 20, computer engineering student currently study abroad. The bot watches Facebook Marketplace, Wallapop, Vinted, and Mercari at the same time and pings my Discord the second a listing matches my filters. The repo is here, free and open source, https://github.com/ethanashi/fbm-sniper-community

The 5 hours roughly broke down to 90 minutes of messaging sellers, 2 hours of pickups, and the rest of the time was packing and shipping. The bot is doing the searching, all I'm really doing is closing.

This week's sold listings, all in GBP since I'm running on eBay UK right now,

• MBP 16" M3 Pro, bought £1,250, sold £1,549, +£299
• MBP 14" M2 Pro, bought £780, sold £999, +£219
• MBP 14" M4, bought £720, sold £899, +£179
• iPad Pro 12.9" M2, bought £480, sold £625, +£145
• AirPods Max Silver, bought £240, sold £329, +£89
• Apple Watch S10, bought £255, sold £329, +£74
• Dell Inspiron 15, bought £120, sold £179, +£59
• Akai MPC Studio, bought £40, sold £74.99, +£35
• PS5 DualSense Camo, bought £25, sold £49.50, +£24.50
• PS5 DualSense White, bought £20, sold £39.99, +£20

After eBay fees and shipping that nets out to roughly $1,437 USD.

The playbook that's been working,

1. Speed is the entire edge here, and I cannot overstate it. The bot pings my phone the second a listing goes up, I reply within 60 seconds with the exact same message every time, "Hi, still available, I can pay today." Most of these flips were locked in before the listing was 10 minutes old. You aren't competing on price in this game, you're competing on response time, and a script that runs while you sleep beats a human refreshing the app every couple minutes.
2. Apple gear has been the bread and butter for me, and Macbooks in particular. Three Macbook Pros this week alone did £697 in combined profit. The mispricing on Macbooks is the cleanest I've seen anywhere, because the average seller prices based on what they paid two years ago, not what eBay sold comps actually say the market will pay today. The M2 Pro at £780 was a guy upgrading to an M4 who just wanted his old machine gone the same day, and the bot caught the listing about 3 minutes after it went live.
3. The filter recipe I keep recommending to anyone who asks. You pick the specific model you want, set a max price around 60-65% of eBay sold comps for that exact spec, and exclude these words in the listing text, "icloud, locked, cracked, parts, for repair, read description." That exclude list alone cuts about 80% of the time-wasting pings before they ever hit your phone.
4. The smaller flips are still worth chasing because the marginal time cost is basically zero. Those two PS5 controllers and the MPC pad together did £79.50 in profit on items I would've completely ignored if I was searching manually. When the bot is doing the discovery, you don't have to be selective about size, you just have to be selective about margin.

Now the actual reason I'm posting,

I'm looking to bring on a few people to help me grow the Pro version of the bot. The free version stays free and open source, that's not changing. The Pro version is the hosted plug-and-play one for people who don't want to self-host or write their own filter configs. What I'm offering is recurring commission for every subscriber you bring in, paid out monthly for as long as that subscriber stays active. If you have a flipping audience on YouTube, TikTok, Instagram, or even a decent following in a relevant Discord, I genuinely want to work with you and the deal is generous. Drop me a DM here or hit the Discord and message me directly, https://discord.gg/dWWaSxuxdU

Happy to answer anything about the filter setup, why Macbooks print so consistently, the affiliate split, the bot itself, or anything else. AMA in the comments.

A few months ago I'd never written a line of code. Today my first app is live on the Play Store. Still kind of processing that.

It's called Migraine Flow. I built it because the existing migraine apps frustrated me — bloated, demanding way more permissions than a health app should need, or locking basic tracking behind a subscription. I wanted something simple and privacy-first.

What it does:

All data stays on your device. No account, no login, nothing sent to a server.

A dark "Relief Mode" with calming audio for when you're mid-attack and light is unbearable

Barometric pressure tracking on a 72-hour view (pressure swings are a huge migraine trigger and most apps don't do this well)

Symptom/pain logging, daily check-ins, an insights dashboard

I built it with AI tooling (Claude Code), which honestly was the easy part. The stuff nobody warns you about was harder: app store rejections, privacy policy requirements, a mandatory 14-day closed testing period with 12 testers, and figuring out Google Play Console as a total beginner. Got rejected, fixed it, resubmitted, and it finally went live today.

It's free with an optional Pro tier for the long-term pressure tracking.

Not really here to hard-sell — I'm more interested in feedback from people who build things. What would you prioritize next? And for anyone who's shipped a first app: what do you wish you'd known about the marketing side, because that's the part I'm figuring out now.

Hi everyone, whether you're using AI for the first time or you're the CEO of Anthropic, this problem affects you.

Let's face it, AI models are strong enough to handle almost anything. Now it's about how do we use them the proper way, let me prove that we have a long way to go.

Go to my tool and write your goal for any AI (LLM, media generation, coding). Something like "Help me fix the X problem" or "Help me create X."

It will analyze what you are trying to do, ask you questions and help you turn your request into a professional brief, that contains every detail that your project needs and is structured by the latest prompt engineering standards. Launch it in your favorite AI tool (free models are fine), you will see the difference instantly.

Try it once and share your thoughts, I am trying to collect the feedback and don't hold back any critique either please.

Here’s proof before yall get on me lol: https://imgur.com/a/tGR0P7T (sub doesn’t allow images in the post).

Quick rundown of what happened:

Two weeks ago I open-sourced a Facebook Marketplace sniper bot I’d been using personally and posted it on Reddit. The bot watches Facebook Marketplace, Wallapop, Vinted, and Mercari at the same time and pings your Discord when a listing matches your filters. Started the Discord at 0 members.

Today: 700+ members, $18,000+ in confirmed collective flip profit. Real number is higher because full-time users don’t post every deal. There’s a free open-source version and a paid Pro tier that funds the infra and the next builds.

I’m 20, computer engineering student, studying abroad in Madrid. Wanted to share the actual lessons from going from 0 to this in 14 days because most of the takeaways weren’t what I expected.

Lesson 1: Ship the version you’re embarrassed by.

I sat on this bot for 3 months before posting it. Kept telling myself I needed to add one more feature, fix one more edge case, polish one more part of the README. None of that mattered. The version I eventually posted had bugs in it. Users found them in the first 6 hours. They also told me exactly which ones to fix first, which I would have spent weeks guessing about on my own. The feedback loop you get from real users in 24 hours is worth more than 3 months of solo polishing. If I’d shipped in month one, I’d be 8 weeks further along than I am right now. The cost of waiting is way higher than the cost of looking unfinished.

Lesson 2: Your first 100 users will tell you what your product actually is.

I built this thinking I was making a Facebook Marketplace bot. Within the first week, users were running it on Vinted way more than FB and finding better deals doing it. I had built Vinted support as an afterthought. It turned out to be the killer feature. I had to update my own pitch to match what users were actually doing with it. The product I think I built is rarely the product that works. If your earliest users are gravitating toward a feature you considered secondary, that’s the signal. Pivot the marketing, double down on that feature, and let the original “main” feature fade if it has to.

Lesson 3: Community work is the actual job after launch.

The product was 80% built when I posted. The 14 days since have been almost zero coding and almost entirely community management. Answering Discord questions, writing Reddit replies, helping users debug their setups, handling edge cases I never anticipated. I spent more hours on customer success in 2 weeks than I did building the thing in 2 months. Founders who think they can ship and then go back to building the next feature are wrong. The community is the work now. The good news is this is also where the real product insights come from, the ones you’d never get from your own head, so the time isn’t wasted, it’s just a different kind of building.

What I’m building next:

Started on a car flipping version. Same core idea applied to a higher-ticket vertical. Runs online instead of locally so it works on your phone at auctions, scans FB Marketplace and Craigslist, pulls real-time pricing comps, decodes VINs with full options and trim breakdown, flags rebuilt and salvage titles automatically, calculates true wholesale value and max buy price, AI scores the listing photos for body/interior/tire/engine condition, and suggests negotiation angles based on what it finds wrong with the car.

Got 5 real car flippers in the Discord helping me test it right now. If you flip cars and want to mess with it when it’s ready, drop a comment.

Happy to answer anything about the build, the launch, the community side, pricing decisions, the next product, whatever.
