Hey everyone!

I built Pixel Circle Builder, a free browser tool for creating Minecraft circle, oval, and dome blueprints.

Quick update for anyone who followed us at launch

AI coding tools are incredible and they quietly ship security holes: a

Supabase table with RLS off, an API key sitting in the frontend bundle, a

"god-mode" endpoint with no auth, a chatbot that leaks its system prompt if

Hey everyone

I've been building SigVela a free signature generator that models actual pen strokes (speed, taper, pressure, seeded randomness per letter) instead of just rendering your name in a cursive font like most tools do.

It's 100% client-side (no backend, no signup), and covers three real use cases: typed handwriting-style signatures, freehand drawing with smoothing, and direct PDF signing with multi-page support.

Launching on Product Hunt on September 2nd would genuinely love feedback before then, especially on:

Building in public and wanted to share what I m shipping.

LexScan lets you paste any contract or just describe your situation in plain English and get a structured legal memo back: red flags, severity scores, what to negotiate, what to walk away from.

The use case is the gap between I can t afford a lawyer for this and I have no idea what I just signed. A lease, a freelance agreement, a SaaS subscription with a 90-day cancellation trap buried on page 4.

5 free analyses, then $9 for 50. No subscription. Credits never expire.

Games that have been updated for many years create an interesting information-design problem. A single latest version page is simple, but it can hide the events, compatibility changes, and features associated with earlier releases.

Shadow Fight 2 is a good example. Its core fighting and RPG systems have remained recognizable, while different releases have introduced seasonal events, raid content, characters, and technical changes. Someone researching the game may want the newest release, but another user may be looking for information about a particular event or an older Android device.

I m working on Play Mod Game, an Android game and version discovery catalog. For our Shadow Fight 2, we use a central game page supported by separate articles about notable versions and game content.

Evil corporations want to track your every move.

That s what the internet will tell you

At one very specific task: identifying a creator-fit opportunity before the resulting content becomes public.

A few days ago, Tukey s Opportunity Radar surfaced this opportunity for Marques Brownlee:

I m building AIUNSEEN Studio, a small software studio working on web apps, automation, and AI-ready website infrastructure.

One problem I keep seeing: a website can look clear to humans, but still be awkward for AI assistants to understand.

For example, ChatGPT, Gemini, Claude, or Perplexity may need to piece together services, products, prices, locations, FAQs, and contact or booking actions from many different pages before they can answer confidently.

So I built a free AI SEO/AEO audit that asks a simple question: can AI assistants understand what this public website offers?

Hey PH Community!
We spent years building AI agents for private markets. The models kept getting better. The data underneath them never did.
Anyone who has tried knows the drill. The good databases want an annual contract before your first query. The search APIs sell you volume, then your agent burns tokens working out that six of the ten results are the same story.
So we built akta.pro.

• Company data, pay-as-you-go. 20M+ companies, 2x the coverage of PitchBook and 4x the depth of ZoomInfo or Apollo. Fundamentals like firmographics, revenue, valuation and funding, plus the fields most databases skip: competitive moat, GTM motion, tech stack, AI maturity.

• News, not just search. Monitor a company, a sector, or a topic in your own words. Deduplicated, matched to the right company, scored for impact, tagged across 100+ event types so you can build your own triggers. Costs 10x less than running event detection through a search API.

• Alt signals on the same ID. Headcount, web traffic, jobs, social, reviews, all tied to the same company ID as the data and the news.
  Available as API, MCP and CLI. Free to try, no card required.
  We are here all day. Tell us what is missing or what you would want next. Appreciate any feedback!
