While learning AI-assisted building with Antigravity, I needed a real project to practice on. I built buildmysignature.com a free email signature builder with CTA buttons, clickable social media icons, custom banners, and live preview.

As a designer always hunting for clients, I send a lot of cold emails. At some point I realized my signature was untapped real estate in every single one of them. So I looked at existing tools most lock features behind a signup, watermark your output, or generate HTML that breaks in Gmail and Outlook.

So I built what I needed. If you're a freelancer, sales rep, recruiter, solopreneur anyone sending cold emails or pitching clients this is for you. Especially the CTA buttons and clickable social icons. Those two alone make every cold email work a little harder.

No signup needed to test it

I sell Next.js website templates, and the thing that annoyed me most as a buyer in that market is that you usually cannot see the product before you pay. You get three screenshots and a promise.
So every one of my 20 templates is deployed and browsable, free, right now: https://cenkkurtoglu.com/templates
Every card there has a live demo link to the deployed site. Click through, open the sub-pages, resize the window. If they are not what you want, you have lost two minutes instead of $79.
What they are: 20 multi-page starters, one per niche (SaaS, agency, e-commerce, real estate, restaurant, gym, dental clinic, hotel, law firm, course platform and ten more). Next.js 15.1, React 19, Tailwind 3.4, 5-8 pages each, editable TypeScript source, commercial licence for client work.
What they are not, stated plainly because I would rather lose a sale than an argument later: these are frontend starters, not full-stack SaaS boilerplates. Forms, cart, booking, auth and checkout are demo UI. You replace the placeholder content and wire your own backend. If you need auth and payments already working, buy a boilerplate instead, not this.
One bundle, all 20, $79 one-time. It is on Product Hunt tomorrow morning. I am not going to ask anyone here for anything on launch day, but if you have used template bundles before I would genuinely like to know: what made you regret a purchase? I would rather fix it before someone pays than after.

I ve launched my first app and I m very happy and satisfied about it.

My app creates digital wallet native loyalty cards and I m super excited to share that I have my first 7 subscribers!!! I don t have many people to celebrate with as I live alone. So I am sharing the news on here.

Something has been bothering me lately.

A few years ago, if you wanted to build a product, you'd probably sketch a user flow, write down some requirements, or at least spend time thinking through the idea before writing code.

Today, many of us skip that step.

We open Cursor, Claude, Lovable, or Bolt and start typing.

We are building FounderFlow around a painful founder experience.

I opened an important government-related email.

I completed one portion of the required survey.

I'm still building this cash flow simulator for trade businesses (electricians, HVAC, plumbers, small subcontractor crews, 3-15 people). I've got a handful of features I think are solid, but I honestly don't know if they're solid enough that someone would actually pay for this so throwing it out there.

What I'm planning:

• Monte Carlo simulation instead of one flat forecast number, so you see a range of outcomes instead of getting blindsided. is this actually useful, or overkill for a small crew that just wants a simple number?

• Pre-built templates by trade (electrical, HVAC, plumbing, subcontracting) so you're not starting from scratch. worth it? Its a good basis for businesses to already build off of, but these industries might be too nuanced?

• QuickBooks integration, so it pulls real numbers instead of manual entry. This feature seems to have the most apparent upside and just nice to have either way, but you can never be too sure if it will actually provide value.

• Models retainage (the payment chunk jobs hold back until work's fully done) using your own job history. I don't know how much this actually messes with people's day-to-day cash flow.

• Another feature I wanted to add was a benchmark system that lets you compare your numbers to others in your niche. curious if owners even want that, or if it feels pointless.

I am not trying to build features nobody asked for. If you run a trade business, or just know something business related, would any of this be worth paying for, or am I solving a problem that isn't really one?

Hey Product Hunters

I m a solo developer building NovaCapture.

Hey all,

Solo dev here, been writing software since my first Tandy Color computer in 1981. (loved that thing!)

After watching Meta acquire Limitless/Rewind in December and shut it down weeks later taking EU users' data with it I decided to build MyHandler. (https://MyHandler.AI)

Hey everyone! My co-founder and I have been deep in indie author communities and kept seeing the same horror stories authors using review exchange platforms, getting flagged for review manipulation, and losing their Amazon accounts permanently. Reviews gone, books delisted, years of work undone overnight.

The problem wasn't the concept of review exchanges. It was how they were built. Direct swaps and credit loops are exactly what Amazon's bots are trained to catch.

So we built TikiRead, authors launch campaigns, readers earn points for honest reviews, no direct swaps between the same two people. Reviewers have to submit the full review text and live Amazon URL before getting any credit, with accountability built in at every step.

Free tier to try it out, launching officially on Product Hunt next Tuesday (June 23). Would love feedback from this community before then: tikiread.com

Hey everyone, I am new here, still learning the ropes on Product Hunt discussions.

I'm building XC0MRADE, a cybersecurity/compliance platform built India-first (CERT-In, DPDPA, RBI frameworks), with Turin at the core: a full-stack DAST engine doing API fuzzing, cloud access-control audits, and automated compliance reporting. Built rigorously for Indian regulatory depth, but the underlying testing engine works for any company that needs to continuously test and prove their security posture, not limited to India.
