Requestly is an open-source API development and testing tool that combines the capabilities of an API Client and HTTP Interceptor, making it a better alternative to Postman + Charles Proxy.

AppErgo's answer:
AppErgo was created in France in 2026 as an independent project developed by a solo creator. Its name combines “App”, for applications and online tools, with “Ergo”, reflecting a focus on ergonomics, simplicity and ease of use. The project started with a small collection of practical tools and gradually grew into a toolbox of more than 200 tools covering text, codes and puzzles, dates, audio, games and everyday tasks.
AppErgo's answer:
AppErgo is primarily built with static HTML, CSS and vanilla JavaScript. Its pages are generated through a custom administration system based on PHP and MySQL, while the public tools rely on standard browser technologies such as SVG, Canvas and the Web Audio API. All processing takes place directly in the browser, without external APIs or remote processing services.
AppErgo's answer:
AppErgo is built for people who want to open a tool, complete a task and move on. It combines more than 200 fast, lightweight and responsive tools with clear interfaces and local browser processing. There is no signup, no intrusive advertising and no unnecessary upload of personal data. The tools are available directly on desktop and mobile, without installing anything.
