I wanted around 20 TH/s at home under 400W, and it took me two weeks of spreadsheets to even try to decide where to buy. The listed price was never what I'd actually pay: VAT differs by country, some shops show prices with VAT and some without, and new devices kept appearing so I kept starting over.

So I made minerdeals.eu. It compares 7 EU shops, home and industrial miners, applies your country's VAT, and sorts by cost per TH and efficiency.

The weak spots, honestly: shipping estimates are rough because shop shipping rules are messy, there are only 7 shops so far, and nothing is verified against real buyer receipts yet.

I didn't build it to make a living. I built it because I couldn't decide where to buy, and if nobody else uses it, it already did its job for me. A couple of shops gave me affiliate links that I use, and they don't affect the ranking. At most it might pay for hosting.

Hi PH, Noor here, solo founder of Ember (emberai.site). Ember runs on Groq's gpt-oss-120b. My first rate-limit errors (HTTP 429) didn't come from users. They came from running my own test suite. So before I market anything, I did the math. Everything below is my estimate, not measured on production.

The numbers: Groq lists this model at about $0.15 per million input tokens and $0.60 per million output tokens (from third-party pages; I'm verifying in my console). A first roast uses roughly 6,000 tokens. A signup that also generates a plan is roughly 15,000. A check-in makes 5 sequential model calls, about 8,000 to 10,000 tokens. That works out to about half a cent per full signup, and roughly 10 cents a month for a free user who checks in daily.

Where it actually breaks: not on money, on speed limits. I'm on Groq's free plan today: about 30 requests and 8,000 tokens a minute, which is less than one signup's worth every two minutes. The paid developer tier is reported at around 250,000 to 300,000 tokens a minute, about 17 signups a minute. So 1,000 people signing up in the same hour would need about 15 million tokens, roughly an hour of queueing.

What I'm doing about it: upgrade before marketing, set a spending cap, make the model name swappable (it's copied into 5 files right now), and plan a second provider. The same model is listed cheaper on other hosts, so a backup could also save money.

I am building DueNest at Colworks for a small, easily overlooked task: remembering an important date after you have already checked it.
If you live, study, or work abroad, you can enter a passport-validity, program-end, or other confirmed date, choose a timezone and reminder intervals, and review the schedule. There are no passport scans or document uploads. DueNest does not determine immigration status or calculate legal deadlines.
The free beta works in phone and desktop browsers. The site now includes a passport-date example and a quick-start FAQ:
https://colworks.com/duenest/?ut...
I would value a small first-use test: try creating one reminder and tell me which step was unclear. Please do not post document details, private dates, or sign-in links. Keep a separate reminder for critical dates; email inbox placement is not guaranteed.
For people already using a calendar: what would a separate reminder tool need to do better to earn a place in your workflow?

Hi Product Hunt community!

One challenge in HR technology is helping organizations connect employee goals, performance reviews, recruitment, and professional development in a more structured way.

That's one of the problems we're working on at Third Bracket.

Third Bracket is an HR technology platform focused on performance management and talent processes, with solutions covering recruitment, HR analytics, assessments, employee recognition, and talent development.

Take a pic of wherever you want and then input the details of the project you are planning. In a couple seconds you can have a material list, what permits you need, who you have to contact, unforeseen issues that may arise and that's just the beginning. Contractor Sight keeps track of finances, fleet and equipment maintenance and customer communication. You can add measurements to your photos for more in-depth analysis and you can upload your blueprints and have them superimposed on the photo. Contractor Sight also features an "Ask Joe" button which allows the latest Open ai Astra to chime in on your project. I have a lot more planned for future roll outs so stay tuned. Also download contractor sight now for free and give it a try. I'd love to know what you think. Contractor Sight by Kreischtech launched today on product hunt or go to my website or Google play Kreischtech.vercel.app.

Hi Product Hunt! I recently launched Danmu Bilingual Keyboard on the China App Store.

The idea is simple: when typing Chinese with Pinyin, English glosses appear alongside the Chinese candidates, so you can pick up vocabulary without switching to a dictionary.

The keyboard works offline for Pinyin input and glosses, and keeps its learning data on-device. It doesn t require Full Access. The companion app includes a vocabulary notebook with manual editing and JSON import/export.

A little about the build: I brought a platform-independent Rust input core into an iOS Keyboard Extension, then built the surrounding app in Swift/UIKit. The extension has strict system boundaries, so keeping input and learning local became an important part of the design.

Hey everyone!

I built JSONexLab 7 B2B APIs for trade, finance, compliance, all on the same stack (Cloudflare Workers + D1 + KV + R2).

The problem: small trade/fintech teams spend $500-2000/mo on separate vendors for HS codes, sanctions screening, document parsing, finance validators. I bundled them into one platform with free tiers.

What's live:

I've spent the last decade in eCommerce and media buying, and for the past 8 months I've been building omnicheckout.app on top of an event tracking system I already had running. End result is a checkout platform that lets merchants take payments in environments where a processor ban would otherwise be a business-ending event, with world-class tracking built in underneath rather than bolted on. Stripe and Whop are the two processing partners live on it today, and merchants can either run their whole setup through us or plug in their own integration and let us just manage that connection.

I built this mostly by directing AI on architecture while learning TypeScript, terminal, and databases alongside it, which is enough for me to chase down real issues fast when they show up. Current focus is hardening the payment webhook logging so observability is airtight.

What I need now is someone who can actually sell and promote this, because that's not me. Looking for a co-founder or COO for that role. I'm also open to a UI/UX designer, since I can hold my own on design but not against someone who's built a career on it. Both are equity-only right now since we're not funded, the company is an LLC moving to a C corp shortly, and there's provisional patent coverage on identity resolution and edge technology, some of it close to expiring and already positioned to convert to utility patents cheaply.
If this sounds like something you'd want in on early, reach out and let's talk. Happy to walk through the platform, the tech, or the patent situation in more depth.

Every architecture diagram I've drawn by hand was out of date within a week.

So I built TF Diagrams, and today I launched it on Product Hunt

It reads your Terraform and draws the AWS / GCP / Azure diagram for you, in your browser. It's free, there's no sign-up and nothing gets uploaded.
