Hoppscotch started life as Postwoman — a browser-based API client created as a fast, free, open-source alternative to Postman. The name changed to Hoppscotch in 2021, but the mission stayed the same: give developers a full-featured API testing tool they can open in any browser, with nothing to install, no account
Testing
Choosing an API client in 2026 is more complicated than it was five years ago. Postman has moved aggressively toward the cloud and enterprise. Insomnia changed owners and briefly required login for basic use. Bruno emerged as the Git-native alternative. Hoppscotch runs in the browser. Thunder Client lives inside VS

Insomnia is one of the most polished open-source API clients available. Originally built as a lightweight Postman alternative focused on great UX, it was acquired by Kong in 2019 and has since evolved into a full-featured platform with REST, GraphQL, and gRPC support, an OpenAPI design editor, a powerful plugin

In 2023, Postman announced it was sunsetting its free Scratch Pad — the local-only workspace that kept collections entirely on your machine. If you wanted to use Postman, you had to sync everything to Postman's cloud. For teams that work with sensitive APIs, financial data, or internal microservices, that
Testing
Most developers know how to send an API request. Fewer know how to build an API test suite that stays reliable as the API evolves, runs consistently in CI, and actually catches regressions before they reach production. The difference between a collection of saved requests and a genuine test suite

WCAG 2.1 — the Web Content Accessibility Guidelines, version 2.1 — is the international standard for web accessibility. Published by the W3C in 2018, it defines how to make web content accessible to people with disabilities. For developers, the challenge isn't understanding the principles (they're sensible)
Testing
End-to-end accessibility tests catch page-level violations. But component-level accessibility bugs — a missing label on a custom dropdown, an ARIA role on the wrong element, a modal that doesn't trap focus correctly — are best caught in unit tests where feedback is fast and failures are isolated. jest-axe brings the
Testing
A developer changes a global CSS variable — --spacing-base: 8px becomes --spacing-base: 10px. All unit tests pass. All E2E tests pass. But twenty components now have slightly different spacing, the header overlap looks wrong on mobile, and a dialog's close button is partially hidden. No test caught it because

Percy is a visual testing platform from BrowserStack that integrates directly with Cypress and Playwright. You add a single command to your tests; Percy captures screenshots, compares them against approved baselines, and flags visual differences in a pull request review workflow. This tutorial covers setup for both Cypress and Playwright,

Visual regression testing tools have proliferated over the last five years, and the differences between them matter. Choosing the wrong tool for your team's context means either paying for features you don't need or missing capabilities that would save hours of manual QA. This guide compares

Cucumber and Selenium are a classic combination: Cucumber provides the human-readable scenario layer, Selenium drives real browsers underneath. Together they deliver automated acceptance tests that non-technical stakeholders can read and engineers can run in CI. This guide covers the complete setup — Maven project, Page Object Model, parallel execution, and GitHub

Jest snapshot testing is simultaneously the most misused testing feature in the React ecosystem and genuinely useful when applied correctly. Teams either avoid it entirely (too fragile) or over-use it (snapshot everything and update blindly). Neither is right. This guide covers how snapshot testing actually works, when it provides real
