Building a Superhuman-Style Collaborative Email Editor with Next.js and Velt🔥
IntroductionSuperhuman rethinks email as a fast, focused workspace. Its clean interface and keyboard-first flow make working through email feel deliberate instead of noisy.Adding collaboration to this kind of experience is where things get difficult. Real-time updates, user presence, inline comments, and notifications usually require complex backend systems and real-time infrastructure.In this tutorial, we’ll build a Superhuman-style collaborative email interface using Next.js and Velt. Th
Three Stripe subscription patterns I locked in before going live (with code)
I've been building and running a small SaaS (GramShift, Instagram automation desktop app) on Stripe subscriptions for the past several months. Getting the basic checkout flow to work was easy — what took more careful design were three implementation patterns where the docs mention the risk but it's easy to skim past.Sharing the three I locked in during the build phase, with the code I actually use. I caught the first one during local testing, before it could hit a real customer, and that's the v
Meet @vysmo/effects — 30 WebGL2 filter effects in one render() call
There's a category of visual work the browser is genuinely good at and yet most projects either skip or reinvent: putting a filter on top of an image or a video. Blur a hero photo. Glow on hover. Halftone for the print-design aesthetic. ASCII for the terminal vibe. A scanline VHS pass for nostalgia.You can do these in WebGL, but the gap between "I want a bloom on this image" and "working ping-pong framebuffer pipeline with HDR float targets" is wide enough that most people give up and reach for
Introducing Bombie: A Drag-and-Drop Builder for Material-UI in React
Most of the time, building a React UI with Material-UI looks like this: open the docs, copy a <Button variant="contained" color="primary">…</Button>, paste it into your component, tweak props, save, alt-tab to the browser, reload, repeat. It works — but for sketching layouts or onboarding new developers to MUI's prop surface, the loop is heavier than it needs to be.Bombie is an experiment in shortening that loop. It's a drag-and-drop visual builder for Material-UI in React. You drop
Why I Abandoned Global Ecommerce Platforms for a Custom Solution in Emerging Markets
The Problem We Were Actually SolvingI still remember the day I received an email from a potential customer in Cameroon, interested in buying our digital products but unable to complete the transaction due to payment gateway restrictions. This was not an isolated incident, as we soon discovered that many creators in countries like Nigeria, Pakistan, and Bangladesh faced similar challenges when trying to sell their digital products online. The problem was not just about payment gateways, but

Lint Your Phishing Templates Like You Lint Your Code
You spent two hours crafting a convincing IT helpdesk pretext. You ship the campaign. The click rate is 2%.It's not because employees got more savvy. It's because half your emails landed in spam, your tracking pixel was broken so you never saw the opens, and your {{.FirstName}} was actually {{.first_name}} and rendered as a literal string in every recipient's inbox.I built @hailbytes/phishing-template-linter after the third campaign in a row where this happened.

Why Crypto Payments Are Still a Pipe Dream for Digital Creators in Developing Countries
The Problem We Were Actually SolvingWe weren't just trying to add a new payment option to our system; we were trying to level the playing field for digital creators in countries where access to the global digital economy is severely limited. For these creators, receiving payments from customers in other countries is often a bureaucratic nightmare, requiring them to jump through hoops to get a domestic bank account or shell out thousands of dollars to set up a foreign bank account. Many sim
How I built an itinerary validator for AI travel plans
AI travel planning is useful until the itinerary becomes a real Tuesday at 3 p.m.That is where the failures appear. A model can write a clean five-day Paris plan. It still does not know that the museum day lands on the weekly closure, that the restaurant moved, or that a timed-entry attraction sold out before the trip.I built ValidaTrip as the validator step after the AI draft. It does not write the trip from scratch. It takes the plan you already have and checks whether it works on the ground.
The False Tradeoff Between Payment Flexibility and Regional Conformity
The Problem We Were Actually SolvingThe real problem here was not finding a payment processor, but rather ensuring our platform was compliant with regional regulations and able to handle transactions in multiple currencies. We knew customers would expect seamless payment experiences, regardless of their location. However, our research revealed that even popular payment gateways had restrictions in certain countries, leading us to reconsider our choices and explore alternative solutions tha

The Tyranny of Payment Gateway Lock-in
The Problem We Were Actually SolvingOur goal was to build a payment system for a digital marketplace where creators from all over the world could sell their products and get paid in their local currency without incurring massive conversion fees. The system had to be scalable, secure, and easy to integrate for developers. What We Tried First (And Why It Failed)We started by integrating Stripe, a well-known payment gateway, with our system. However, as our client base grew, so did the f
The Lie We Tell When Platforms Fail Us
The Problem We Were Actually SolvingWe wanted to create a seamless checkout experience for our users, allowing them to purchase Notion templates directly from our website without any fuss. With millions of Notion users worldwide, we were convinced that Gumroad was the answer, given its reputation for ease of use and platform integrations. It was our go-to solution for a frictionless sales process, or so we thought. What We Tried First (And Why It Failed)My team and I attempted to inte

How We Built a Payment System Venezuela's Government Didnt Block (And What It Cost Us)
We needed a way to pay digital creators in Venezuela when every mainstream platform locked us out. PayPal froze accounts without explanation. Stripe rejected our Venezuelan bank details. Gumroad and Payhip didnt even ship integrations to our region. The problem wasnt our code—it was the platforms themselves. They treated Venezuela like a compliance risk, not a market. So we built a system that worked around the restrictions, and it nearly broke us in the process.The first attempt was a patchwork
The Limits of Checkout Platforms: Why We Walked Away from Stripe
The Problem We Were Actually SolvingWe were trying to build an inclusive checkout experience that worked seamlessly in over 190 countries, including those where traditional payment gateways like Stripe, PayPal, and Gumroad do not support transactions. Our customers' success was directly tied to our ability to process payments across borders, and yet, our attempts at using these popular platforms kept hitting roadblocks. It wasn't a lack of technical expertise or resources, but a fundamenta
React Server Components Don't Make Your App Fast by Default
A Next.js app migrated from Pages Router to App Router. RSC throughout, use client pushed to the leaves. Lighthouse score went up. LCP in production got worse by 800ms.The component tree was fetching data. Each server component called its own database query. They ran sequentially — one couldn't start until its parent finished. What was previously one getServerSideProps call became eight round trips before the page could render.RSC reduces client JavaScript. That part works exactly as advertised.
