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 designed for students, teachers, developers, creators, office workers, puzzle enthusiasts and everyday users who need a practical online tool without creating an account or navigating a complicated service. Its wide range of tools supports both occasional tasks and regular use on desktop or mobile.
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.
AppErgo's answer:
AppErgo is primarily designed for individual users rather than named enterprise customers. Its audience includes students, teachers, developers, creators, puzzle enthusiasts and anyone looking for a quick browser-based tool.

Armed with this you could now investigate the raw JSON using HTTP proxying (I like to use ProxyMan for this), and/or talk to the back-end team, see if they've made some changes and are aware of the breakage in the contract between client and server. - Source: dev.to / almost 2 years ago
I previously used Proxyman [1] on iOS to the http requests send over TLS. It worked rather nicely. Proxyman in this case starts a VPN which handles all the traffic. It uses custom certificate to decrypt the messages. [1] https://proxyman.io/. - Source: Hacker News / almost 3 years ago
