About this app

Phone Mock HTTP Server runs an HTTP or HTTPS server on your smartphone. Requests from an MCU, ESP32 or PC program get the responses you set, so you can test communication before a real server exists.

Main features
• Start and stop an HTTP or HTTPS server on a port you choose
• This phone's address shown, ready to copy
• Add, edit and delete fixed response rules by method and path
• Set the status code, Content-Type, headers and body
• Delay a response to test timeouts and retries
• Test error responses such as 500
• A path with no rule gets 404; another method gets 405 with an Allow header
• Request log: time, sender IP, headers, body, the response and time taken
• Make a rule straight from a logged request
• A notification keeps the server running with the screen off or another app in front
• HTTPS with a PEM certificate and private key you provide
• Four example rules included from the start
• A user guide with pictures, Korean and English
• No login: everything runs on your phone

Good for
• Testing firmware HTTP requests before the backend is ready
• Seeing the URL, headers and body a device really sends
• Checking retry logic with error responses and delays

Please note
• While the server runs, devices on the same network can reach it with no authentication. Use it on networks you trust and stop it when you are done.
• Responses are fixed values you set. There are no dynamic scripts or databases.
• The app does not create HTTPS certificates. Add a development certificate made on a computer.
• Android may refuse low ports such as 80. The default port is 8080.
• Guest Wi-Fi may stop devices from reaching each other.
• Do not use it for real services or safety-related control.
• The app shows ads. Ads do not interfere with handling requests.
Run an HTTP/HTTPS mock server on your phone to test MCUs and network devices.
