How to add license keys to a SwiftUI macOS app (in under an hour)

You built a Mac app, you want to sell it outside the App Store, and now you need licensing: a key the customer enters, an activation that sticks, and feature gates that hold up offline. Here's how to do it in an afternoon without standing up a backend. Note: this is cross-posted from the Keylight blog. I build Keylight, so this uses it as the worked example — the shape of the solution applies whatever SDK you choose. Strip away the marketing and every licensing system does exactly three jobs: Activate — turn a key the user pastes in into proof-of-purchase bound to this device.

I compared the licensing tools for my indie Mac app — the honest breakdown

I needed to license a macOS app I sell outside the App Store. I went down the rabbit hole so you don't have to. Here's the honest breakdown — what each tool is genuinely good at, and where it stops. No tool is "best"; they're good at different things. Before the tools, answer these: Do you need real offline verification?

How offline license activation actually works

If you ship a desktop app outside an app store, you eventually hit the same wall: how do you check a license when the user is on a plane, behind a corporate firewall, or just offline? Calling your server on every launch isn't an option. Here's how offline activation actually works, without the hand-waving. The first thing everyone reaches for is "call home on launch, get back yes/no." It works in the demo and fails in the wild: No network = no app. Fail-closed locks out paying customers.

The Day I Confused Task Queues with Message Brokers And Built the Wrong Thing

In my journey as a backend developer, I had already spent time working with APIs, databases, authentication flows, and background processing. I understood the basic idea that not everything should occur within a request-response cycle, especially when dealing with expensive operations such as sending emails, processing files, or generating reports. Offloading work to the background felt like a solved problem to me. That confidence was exactly what led me into confusion. When I first encountered message brokers and task queues, they looked like different names for the same idea.

I built a free AI README Generator (with markdown preview)

Every developer hates writing READMEs. It's boring, repetitive, and always gets skipped. So I built ReadmeAI — describe your project, AI writes the README instantly. Fill in project name, description, tech stack, features Tech Stack Next.js + Tailwind CSS Why I built it (Write 2-3 sentences personally — mention the challenge, that you're a student builder, makes it relatable) https://readmeai-three.vercel.app/ Built this in a day as part of my 30-day AI tools challenge. Would love feedback from the dev community!

🚀 I Built DevBrand AI with Google AI Studio

This post is my submission for DEV Education Track: Build Apps with Google AI Studio. What I Built For this project, I built DevBrand AI, an AI-powered web application that helps developers create a complete personal branding kit in just a few clicks. Instead of manually writing bios, portfolio headlines, README introductions, or designing graphics, users simply provide their GitHub username, role, tech stack, experience, and preferred design theme. The application then generates everything automatically. Prompt Used I used Google AI Studio's Build apps with Gemini feature with a prompt simila

What Is an Agent Registry? (And What We Broke Before We Had One)

TL;DR An AI agent registry is a centralized catalog of every agent in your organization — what each agent does, what tools it can access, what version is running, who owns it, and how to call it It's to agents what a container registry is to Docker images or what a service mesh is to microservices — the layer that makes distributed components governable We hit the "which agents do we have?" wall at 14 agents across 3 teams. That's when the registry stopped being a nice-to-have About four months into our agentic AI buildout, our head of security asked a question I couldn't answer: "Can you give

How Small Can an Agent Model Get? The Nemotron Floor

Most model comparisons ask which model is best. This one starts with a model that never even produced a single result. We tested NVIDIA's open-weight Nemotron family, from the 30B Nano to the 120B Super, on a benchmark of real-world coding tasks: the kind of models an indie developer on a tight budget, or an enterprise cutting inference cost and keeping data in-house, would run. The main finding is that model size is not a dial you turn for a little more quality, it is a threshold. Below a certain capability floor a model cannot drive an agent loop at all, which is why the smallest variant we

DeepSeek vs Qwen vs Kimi vs GLM: Which AI API Wins in 2025?

Honestly, deepSeek vs Qwen vs Kimi vs GLM: Which AI API Wins in 2025? I'll be honest — when I first started comparing these four Chinese AI model families, I thought it would be a quick exercise. Spoiler: it wasn't. I spent two weeks running prompts through every endpoint, tracking every dollar, and tallying tokens like a part-time accountant. The good news?

Vetting an Investor Before You Pitch Them: A Solo Founder's Workflow

Most founders spend weeks polishing their deck and about forty minutes researching the person they're about to send it to. I was one of those founders, and it cost me badly. A few years ago I sat across from a partner at a mid-sized fund and spent ninety minutes walking through MentionFox's traction numbers. He nodded in the right places. He asked smart follow-up questions.

Adding Release Gates to AI Browser Automation Runs With Real Profiles

A Playwright task can pass locally and still fail in a team run. It may open the wrong persistent profile, use the wrong proxy region, assume a session that has already expired, or continue without enough evidence for someone else to debug the run. That is where retries stop helping. For browser automation that runs across real account environments, teams need a release gate. A release gate is a pre-run check that decides whether a task is allowed to continue.

AMCA engine talks hit roadblock, US company raises cost threefold

India's ambitious fifth-generation fighter jet program, the AMCA, faces a significant hurdle as the cost of General Electric's F414 engines has tripled, potentially escalating the project's budget. With the airframe design finalized around these engines and limited alternatives, India may be forced to accept the higher price. This development impacts the timeline for the fighter, which is crucial for maintaining air superiority against regional rivals.
