Why Your Menu API Is Slowing Down Your QSR

 Is your quick-service restaurant (QSR) losing customers due to slow digital experiences? Discover Why Your Menu API Is Slowing Down Your QSR and how it directly impacts customer satisfaction, order volumes, and delivery performance. In the age of digital ordering, even a 2-second delay in your menu API response can translate into abandoned carts and lost revenue.



In this blog, AntStack breaks down the hidden inefficiencies plaguing most QSRs’ API systems—ranging from bloated payloads and outdated infrastructure to lack of caching and poor query optimization. You’ll learn how inconsistent performance across locations, peak-hour latency, and rigid API structures can bottleneck your restaurant's ability to scale and serve customers swiftly.


We also showcase real-world scenarios where QSRs partnered with AntStack to re-engineer their menu APIs using serverless architecture and intelligent caching strategies. The result? Faster load times, dynamic menu delivery, reduced cloud costs, and improved customer retention.


Whether you’re a CTO, product owner, or engineering lead in the restaurant tech space, this guide helps you evaluate your current system and take actionable steps toward optimization.

React Router v7 vs Remix: Understanding the Evolution and What to Use

Image
 Web development has been changing quickly, and developers often need to balance user experience, performance, and productivity. React Router has been a trusted tool for React developers for over a decade, helping manage client-side routing. But as apps became more complex, developers needed more features like server-side rendering (SSR) and better data handling. Remix initially stepped in to address these needs, building on React Router. However, with the release of React Router v7, many of Remix’s features are now part of React Router itself. This has made it important for developers to understand how these tools have evolved and what they offer today. What is Remix? Remix is a full-stack web framework created by the team behind React Router. It builds on React Router’s nested routing and adds features like SSR, improved data loading, and tools for building modern web apps. It focuses on performance, reliability, and creating smooth user experiences. Originally, Remix filled gap...

Beyond Caching: Unconventional Strategies to Achieve Millisecond Latency

Image
 In a world where a one-second delay can mean lost customers and falling revenue, making your application respond in the blink of an eye isn't just a nice-to-have. It's everything. When developers think "speed," the first word that pops into their head is usually "caching." And for good reason! Caching is a fantastic first step. But what happens when it's not enough? Many growing companies, like the radiation safety experts at  Landauer , realize that true, sustainable speed comes from smarter architectural choices, not just a bigger temporary memory. If you've hit a wall with caching and still need to shave off those precious milliseconds, you're in the right place. Let's look beyond the obvious and explore the strategies that unlock truly breathtaking performance. First, A Quick Nod to Caching Let's be clear: caching is great. Think of it like a librarian keeping the most popular books on the front desk instead of running to the back ai...
