Modern Software Development For Today's Systems & Applications
Load Testing Kafka #speedscale #kafka #loadtesting
Message brokers are a critical component of modern distributed systems, facilitating asynchronous communication between services. Load testing message broker integrations requires special considerations since the interaction patterns differ from traditional HTTP-based APIs. Speedscale provides specialized tooling to help you load test applications that integrate with message brokers by.
AI Prediction for 2026
Every technology cycle comes with hype, backlash, and eventually… utility. AI is shaping up to be no different. As we head into 2026, the conversation is already shifting from “AI will replace everything” to “why isn’t this paying off yet?” This shift is heavily influenced by evolving market trends, as businesses and technologists respond to changes in customer behavior, operational patterns, and broader market conditions that shape expectations around AI.

Digital Twins Gone Wild: My Unexpected AI Doppelgänger
I recently tried using AI to create a digital twin of myself. I uploaded a photo, expecting a futuristic, slightly improved version of me… and what did I get in return? A picture of Kim Jong Un. Clearly, AI has a sense of humor—or a very different definition of “twin.” Forget Arnold Schwarzenegger and Danny DeVito.
Streamline Code Testing with Proxymock
Tired of complex setups and running out of memory just to test one component? Learn how to use Proxymock (a FREE tool) to solve your biggest testing headache: component isolation! This demo shows you how to record and mock interactions across a complex React, Golang, and PostgreSQL stack, allowing you to find bugs before they ever hit production. In This Demo: This strategy lets you easily isolate components, simulate customer behavior, and ensure quality with lightning-fast local testing.
How to Test Your React Frontend When the Backend Is Offline #speedscale #frontend #backend #coding
Software development is hard, especially when you have to ensure every component works together; it's an integration maze! And running a full stack (like React, Go, and Postgres) on your dev machine often means one thing: running out of memory! The Fix: We'll show you how to use Proxymock to record your components, effectively letting you run the frontend (or any component) completely isolated.
How to Test Your React Frontend When the Backend Is Offline
Picture this: You’ve spent hours perfecting your React component. The animations are smooth, the responsive design works flawlessly, and you’re ready to test the user flow. You click “Submit” and… nothing happens. Or worse, you get a cryptic CORS error. The problem? Your backend isn’t running. Again.

Mocking PostgreSQL the Easy Way: Simplifying Testing with Speedscale Proxymock
Every developer who's worked with PostgreSQL knows the pain: testing against a real database slows everything down. You need the database running locally, loaded with the right data, and configured to match production as closely as possible. Every time you run a new test or build, you're forced to repeat that setup migrate schemas, seed test data, and clean everything up again. It's time-consuming, brittle, and hard to scale across a team.
JWT Rot: Why Traffic Replay Tests Expire #speedscale #jwt #trafficreplay #apitesting #testautomation
Are your traffic replay tests crumbling because of expired tokens? You've got JWT Rot! When recording production traffic for integration or load testing, the embedded JSON Web Tokens (JWTs) often have a short expiration date. Once those tokens expire, your entire test suite fails, rendering your valuable traffic snapshots useless. Stop wasting time re-recording traffic. Learn how to defeat JWT Rot and ensure your security and API tests run reliably every time!
What I Learned From Building an eBPF-Based Traffic Capture Application
I just finished building Speedscale’s eBPF-based component to capture and analyze network traffic in a Kubernetes cluster, and it forced me to confront some uncomfortable truths about observability. While there were certainly some challenges along the way, particularly in dealing with Go applications, the approach was relatively straightforward.
Shopify Outage 2025: Rise of the Commerce Kaiju
It was a normal day in the land of eCommerce. Birds were singing, dashboards were loading, and merchants everywhere felt cautiously optimistic. Then the ground trembled. A tiny glitch. A flicker. A warning log no one read. And suddenly— BOOM! Shopify burst out of the digital ocean like a gigantic scaly beast that woke up on the wrong side of the server rack. Checkouts froze mid-purchase. Product pages stopped producting. Merchants stared blankly at blank screens. The Commerce Kaiju had arrived.
