What Is API Design? Principles, Best Practices & Patterns (2026)
I’ve seen teams burn weeks untangling API messes that could have been avoided with a couple of days of upfront thinking. Endpoints named inconsistently, versioning added as an afterthought, error responses that just say "something failed" all of it traceable back to the same root cause. Nobody sat down and actually designed the API before…

10 Types of API Testing Explained with Examples (2026)
APIs (Application Programming Interfaces) are the backbone of modern software; they let applications talk to each other, share data, and trigger actions across systems. Before any API goes live, it needs to be thoroughly tested to ensure it works correctly, handles edge cases, performs well under load, and stays secure. This guide covers all major…

API Testing Services: Solutions, Process, Tools & Best Providers
API testing services help organizations validate API functionality, performance, security, integrations, and reliability across the software lifecycle. These services are typically delivered by QA teams, testing vendors, or automation platforms to ensure APIs work correctly in real-world environments. APIs are no longer just backend infrastructure—they are the backbone of modern digital products. Whether you’re building…

Software Testing Strategies: Complete Guide for Dev Teams [2026]
Software testing strategies define how teams plan, organize, and execute testing activities throughout the software development lifecycle. A well-structured testing strategy helps teams detect defects earlier, maintain product reliability, and adopt a strong quality engineering approach for continuous improvement. Modern development environments rely heavily on Agile workflows, microservices architectures, APIs, and CI/CD pipelines. Without a…

API Observability: What I Learned While Debugging APIs in Production
APIs rarely fail loudly. Most of the time, they break quietly while dashboards stay green. These silent failures are often the hardest to detect and the most damaging for users. I learned this while dealing with real production traffic. Everything looked normal until users started complaining. Let’s explore more about how this works. Why API…

Postman Alternative: The Best API Testing Tools to Use in 2026
A Postman alternative is any API testing tool that can replace Postman for sending HTTP requests, automating tests, or managing API collections. The best Postman alternatives in 2026 include Keploy, Insomnia, Bruno, Hoppscotch, and Thunder Client — each suited for different team needs and workflows. More teams are rethinking the role of Postman in their…

Stateful vs Stateless: A Developer’s Real-World Guide (2026)
Why do some bugs only appear after deployment, even when tests pass locally? Early in my backend work, I kept hearing discussions around stateful vs stateless. It felt academic at first, but once I started dealing with scaling issues, flaky tests, and production bugs, I saw how much this decision actually matters. This article is…

Penetration Testing Services to Strengthen Your Security and Reliability
Modern technology (APIs, Microservices, Cloud Platforms, Mobile Apps) is rapidly changing and becoming a target for attackers as they continue to advance and become more sophisticated. Organizations use penetration testing (a form of ethical hacking) to identify weaknesses in their systems and address them before they can be taken advantage of. Keploy supports organizations’ application…

What Does Extensible Mean? A Complete Guide with Examples and Use Cases
Extensibility is conceptually found in the areas of technology (such as Software Development) and System Design. The term extensibility may seem abstract to someone with no previous background in the field; in particular, when you hear phrases like: “Extensible Software”, “Extensible Architecture”, “Extensible API” or “Extensible Testing Tools”, it could be difficult to understand exactly…
