Chad IDE

Chad IDE presents a modern, AI-powered integrated development environment designed to streamline coding by minimizing downtime during AI inference waits and seamlessly blending productivity with light-entertainment features. It integrates directly with agents like Claude Code for auto-completion, smart code generation, and background processing, while offering built-in distractions (games, social feeds, casual browsing) during the 1–5 minute gaps typical of prompt-based workflows, so developers don’t lose context by switching to external apps. With features such as in-IDE gaming, social-media widgets, background processing of tasks, and unified code-/agent-logic streams, it offers to reclaim lost productivity by reducing context-switching fatigue and keeping the author engaged. It also supports extensive customization, background agent execution, fast tab completions, augmented debugging workflows, and is positioned for both hobby developers and professionals.

Gatling Studio

Gatling

Gatling Studio is a native desktop application designed to convert real browser-based user journeys into clean, executable load tests built on the core Gatling engine (Java/Maven project structure) in minutes. It enables users to record a live browser session (or import an existing HAR file), automatically filter out noise (such as static assets, ads, third-party trackers), refine the user-flow scenario (by domain or request type), and generate production-ready Gatling code that can be version-controlled and extended. The resulting project can be opened in an IDE, committed to source control, customized with injection profiles or parameterization, and executed locally with Gatling Community Edition or scaled via Gatling Enterprise Edition. Gatling Studio is aimed at performance engineers, QA teams, and developers seeking to accelerate test creation while maintaining full “test-as-code” practices.

Radon

Software Mansion

Radon is a Visual Studio Code and Cursor extension that turns a code editor into a complete IDE for React Native and Expo apps. It helps developers build better apps faster by bringing previews, debugging, navigation, logs, network inspection, component inspection, device controls, and AI assistance directly into the editor. Radon runs the iOS Simulator and Android emulator inside the Visual Studio Code or Cursor project, so developers can see the app close to the codebase instead of constantly switching windows. It's built-in previews make it possible to develop components in isolation, while the element inspector lets users click an element in the preview and jump directly to the file where the React Native component is defined. The debugger supports React Native breakpoints inside Visual Studio Code with no extra setup, automatically stopping at runtime exceptions and showing the exact line of code where they happened.

Routebase

Routebase GmbH

Routebase is the single source of truth for your APIs. Design your OpenAPI spec once in a visual editor — no hand-edited YAML — and your documentation portal, mock servers, contract tests, and monitoring all derive from that one spec. Change the contract, publish, and Routebase catches what drifted before your consumers do: it validates live responses against the spec and flags every divergence with field-level diffs — missing fields, type mismatches, undocumented additions. Work on specs the way you work on code: branch, review, merge, with breaking-change detection before anything ships. Publish a docs portal on your own custom domain. Spin up realistic mocks so frontend and backend build in parallel. Run contract and security tests against any environment. Every workspace also ships a built-in MCP server, so your AI agents read and act on the same source of truth, under your team's permissions — no glue code.
