How to Find a $10k/mo SaaS Idea with Python & Apify (Geo-Arbitrage)

The biggest mistake developers make is writing code before validating the market. We spend 6 months building a complex web app, launch it on Product Hunt, get 50 upvotes, and then... zero revenue. Meanwhile, smart indie hackers are quietly making $10k/month by cloning successful US apps for France, Germany, Spain, and Italy. This strategy is called App Store Geo-Arbitrage. In this tutorial, I'...

Top 5 Developer Tools to Find Micro-SaaS Ideas Before Coding (2026)

We’ve all been there. You spend 6 months building a beautiful web app, optimizing the database, and polishing the UI. You launch it on Product Hunt, get 50 upvotes, and then... crickets. Zero MRR. The biggest mistake indie developers make is coding before validating. Instead of guessing what people want, smart developers use data extraction and API tools to find existing, profitable markets wit...

Google Workspace Studio Tutorial: Turn Google Forms into a Full CRM - Auto Lead Capture, Personalized Emails & Team Notifications

As a consultant, I've learned one universal truth, The speed of your response determines the quality of your client relationships. When a potential lead fills out a Get in Touch form on your website, they are at their peak level of interest. If you wait 24 hours to email them back, that interest cools down. If you don't log their details in a CRM immediately, they become a lost lead in your inbox...

Non-Intrusive JavaScript Runtime Instrumentation via Chrome DevTools Protocol for Advanced Debugging and Reverse Engineering

Introduction In contemporary web development, debugging and reverse engineering JavaScript applications often resemble navigating a complex, opaque system where critical vulnerabilities or performance bottlenecks can remain elusive. Traditional debugging techniques—such as source code modification, logging, or browser breakpoints—prove inadequate, particularly when confronted with minif...

It is especially helpful when you have complex classes of objects that can be extended in many different ways. In this video, our developer advocates Guillaume Faas and Jeremy Foster discuss the builder pattern and how i...

I Built a Government-Grade Button Clicking Certification Program (Because the World Needs It)

This is a submission for the DEV April Fools Challenge ⚠️ NATIONAL CLICK THREAT LEVEL: ELEVATED Let me ask you something. You use buttons every day. Login buttons. Submit buttons.

Stop Cluttering Your Codebase with Brittle Generated Tests

TL;DR: In the industry, there is a weird habit: if a tool can generate tests, it is considered automatically useful. If you have 300 new .java files in your repo after recording a scenario, the team assumes they have "more quality." They are wrong. Automated test generation often turns into a source of engineering pain, cluttering repositories and burying real regressions in noise. There is a more...

TinyStart

Sometimes I look back through my blogging archives and notice what’s changed over time. For example, I used to write quite enthusiastically about the arrival of a new operating system from Apple. That is no longer the case, to put it mildly. I’m currently holed up on Sequioa, trying to resist all the nudgings to “upgrade” to the tacky design nightmare that is Tahoe. I feel like the protagonist of...

When the Official Theming Path Was Not Enough: Making Kendo Behave in a Mixed Stack

Theming breaks in mixed frontend stacks not because of CSS, but because of lost control over rendering boundaries. To stabilise it, you need explicit style isolation, control over where UI renders (especially modals), and strict limits on composition.Read All

Anyone feel like they are positively impacting society?

I’m a software engineer who currently works in a low stakes and bureaucratic environment. I’m thinking about what to target next, and I’m feeling a bit disillusioned with the tech landscape. I’m curious who here feels like their work is positively benefiting people, and how they contribute to that. If you don’t want to get so specific then maybe even just “I with in X industry doing Y, and I think...

What I Learned About DAO Governance From a 1,300-Year-Old Japanese Festival System (TEAMZ Summit 2026)

I just came back from TEAMZ Web3/AI Summit 2026 in Tokyo — held at Happo-en, a 400-year-old Japanese garden. 10,000 attendees, 130+ speakers, 50 countries represented. But the most important thing I learned didn't come from a session. It came from watching a sumo performance next to a blockchain demo. The Thesis: Festivals Are the Original DAOs I'm building Matsuri Platform, which dig...
