Before redesigning your SaaS landing page, answer these 4 questions

I work on landing page/product design, and something I’ve started noticing is that founders often ask: “Does my landing page look good?” when I think the more useful question is: “Does the page make the right thing obvious?” Before touching the visuals, I’d try to answer these 4 things: 1. What exactly is the product? Try explaining it in one sentence without using words like seamless, powerful, intelligent, next-gen, platform, ecosystem, etc. If someone has to scroll to unders...

After years of using project management tools, I built my own Jira-inspired platform, Alone.

I started as a freelancer a decade ago. Worked directly with clients. Worked with and managed a small team. Hired other freelancers for projects. Also experienced being the client and having people work for me. Over the years I've used quite a few project management systems too. I've hired people. Managed projects. Dealt with clients. Been the client myself. That means I've seen what the person doing the work needs, and what the person paying for the work expects. I had ideas about how I'd ...

Looking for advice on recurring legal contracts for a small US-based digital marketplace

I'm building a small US-based digital art marketplace and need multiple agreements with content owners/artists. As the business evolves, these contracts will need periodic updates, but legal costs are currently around $600–$800 per contract, which is becoming expensive as we scale. How do other startups handle recurring or evolving creator agreements while keeping legal costs manageable? Any recommended approaches or services that allow ongoing attorney involvement without high per-contract fe...

How do you deal with getting "bored" and losing trust in your app right before launch?

Hey everyone, I keep running into the exact same problem with every app or SaaS I build: 1. Research & Validation: I find a product people are already paying for. I plan to build a better version that fixes competitor flaws. 2. Deep Focus: I throw all my energy into building it. Fast dev, late nights, no sleep. 3. Loss of Trust (at 80% done): Because I've been staring at the same product for days, I get bored of it. Even though I built it well and fixed issues other tools hav...

I created an AR Wi-Fi visualizer that rebuilds your home in 3D

This started as a passion project to figure out why the Wi-Fi died in one corner of my apartment, and I ended up building an entire app. You walk through your home with your iPhone, it rebuilds the place as a small 3D model, and the Wi-Fi signal gets painted onto the floors while you walk. Seeing the exact spot where your signal dies on a miniature of your own home is weirdly satisfying 😂 What it does : • 3D home scan - walk through your place with your iPhone and it rebuilds it as a 3D m...

What idea sparked you SaaS product ?

I’ve launched a SaaS recently. I’ve built the app and now we’re doing research and collecting feedback from our target audience to help develop ours better. My question is did most of you guys build a tool that was really to help yourself then you ended up launching. Or maybe a problem in an industry you’re in and you built it to fix that. Trying to figure out if I jumped right to creating an app too quick instead of really dialing in on a problem that irks my soul snd fixing that for mysel...

Advanced GPU Optimization: How can I tech an LLM with CUDA and ROCm? - Part 2

Hey Dev Community! Welcome back! In Part 1, we built the foundation: from vector addition to tiled GEMM, and finally assembled a complete forward pass of a Transformer block using HIP (CUDA/ROCm). But a forward pass without gradients is just a very expensive random number generator. Training an LLM requires the backward pass (backpropagation), an optimizer (like AdamW), and brutal memory management to fit billions of parameters into VRAM. In this second part, we will implement the missing ...

How I mine App Store reviews to find "copy+10%" opportunities (open Actor)

When evaluating a "copy and improve by 10%" app idea, reading competitor reviews one app at a time doesn't scale. So I built App Store Review Miner , an Apify Actor that: Pulls the top-grossing chart for any App Store category/country Fetches each app's recent reviews Classifies low-rated (≤3★) reviews into 13 complaint buckets Ranks which complaints are category-wide (real opportunity) vs single-app issues Flags apps with a "reputation drop" — recent reviews meaningfully worse t...

How to Find and Fix Slow Components

A practical guide to measuring React rendering performance, identifying slow components, understanding render causes, and fixing performance problems without premature optimization. Introduction A React application can feel slow for many different reasons. Maybe clicking a button causes a noticeable delay. Maybe typing into a search field feels laggy. Maybe opening a dashboard takes too long. Or perhaps a component takes hundreds of milliseconds to render even though the UI doesn't look...
