Why Developers and Mobile Engineers Choose Endly
As traditional API clients become bloated with mandatory cloud sign-ins, forced team workspace synchronization, and aggressive data tracking, developers and mobile engineers face security risks with proprietary API keys and backend tokens.
Endly is engineered from the ground up as a zero-cloud, 100% local-first developer workstation. Your request collections, historical runs, auth headers, and environment variables remain in your local browser IndexedDB or native filesystem—never synchronizing to a remote third-party cloud.
Designed specifically with mobile engineers in mind, Endly features a built-in Wi-Fi Mobile Interceptor. Debug production or staging network calls directly from physical iPhone and Android devices over local Wi-Fi without needing heavy proxy software like Charles or Proxyman.
Key Features & Technical Capabilities
📡 Wi-Fi Mobile Proxy Interceptor
Capture, view, inspect, and mock HTTP/HTTPS requests from physical iOS and Android devices connected on the same Wi-Fi network.
⚡ Automated Collection Runner
Execute multi-request test suites sequentially with automated assertion validation, latency charts, and CSV/JSON test report exports.
🔄 Dynamic Environment Variables
Cascading environment variable resolution with real-time {{variable}} interpolation across global, workspace, and folder scopes.
📦 Universal Spec Import
One-click seamless import for Postman Collections v2.1, OpenAPI/Swagger YAML/JSON, raw cURL commands, and HAR network logs.
💻 Multi-Language Code Generator
Instant copy-ready code generation for Kotlin (OkHttp/Retrofit), Swift, Python (requests), Go, Node.js (Axios/Fetch), and cURL.
🔒 100% Offline & Private
Zero cloud sign-in required. High-performance IndexedDB persistence guarantees your API credentials never touch a remote server.
Frequently Asked Questions
What makes Endly different from Postman or Insomnia?
Endly is 100% local-first and zero-cloud. Your workspaces, requests, environment variables, and authentication tokens are saved strictly on your local machine in IndexedDB and never transmitted to external cloud servers. Furthermore, Endly includes a built-in Wi-Fi Mobile Interceptor to capture physical Android & iOS device traffic without installing heavy desktop proxies.
How does Endly capture mobile API traffic from iOS and Android devices?
Endly features a native Wi-Fi Proxy mode. When your mobile phone is connected to the same local network, setting its proxy IP to your workstation routes all HTTP/HTTPS traffic through Endly, allowing instant live request inspection, header analysis, and response mocking.
Can I import my existing Postman collections into Endly?
Yes! Endly supports one-click import of Postman Collections (v2.1), OpenAPI/Swagger YAML and JSON specifications, cURL commands, and browser HAR network captures.
Does Endly work completely offline?
Yes. Endly requires no cloud account or internet connection to manage workspaces, edit requests, execute collection test suites, or interpolate environment variables.
