Requestly's answer
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. It simplifies API mocking, request modification, and debugging with an intuitive no-code interface, enabling developers and QAs to test APIs efficiently.
Roley's answer:
Roley stands out by combining powerful API development, seamless Postman collection migration, localhost API testing, team collaboration, and role management into one lightweight and affordable platform. Unlike traditional API tools that become complex and expensive over time, Roley focuses on speed, simplicity, and developer-first workflows while offering team plans at a fraction of Postmanโs pricing.
Roley's answer:
People choose Roley over competitors because it delivers the core API development features developers actually need without the complexity, slow performance, or expensive pricing of traditional API platforms. Roley makes it easy to migrate Postman collections in just a few clicks, allowing teams to switch seamlessly without rebuilding existing workflows or API requests from scratch.
It also provides smooth localhost API testing, helping developers test, debug, and manage local APIs efficiently during development. Combined with team collaboration, role management, API documentation, and a unified workspace, Roley simplifies the entire API lifecycle in one lightweight platform.
Built for startups, SaaS companies, and modern engineering teams, Roley offers a faster, simpler, and more affordable alternative to Postman while keeping the workflows developers already know and love.
Roley's answer:
Roley was created to simplify API development for modern teams. Many developers loved the core workflow of API tools like Postman but felt that over time these platforms became overly complex, heavy, and expensive for everyday development needs. Most teams only needed fast API testing, collaboration, localhost development, and simple workflows not bloated enterprise features.
Thatโs where Roley started. The goal was to build a lightweight, developer-first API platform that keeps the workflows developers already know while making collaboration faster, pricing more affordable, and migration effortless. With seamless Postman collection migration, localhost API testing, role management, and unified team workspaces, Roley was designed to help developers focus more on building and less on managing complicated tools.
Roley's answer:
Roley is primarily built using modern web technologies including Vue.js for the frontend, Electron for cross-platform desktop support, Node.js for backend and system operations, and Quasar Framework for building a fast, responsive, and developer-friendly user interface across platforms.
