Radar acts as a map for your digital services. When developers build software, they often use a blueprint called an OpenAPI or Swagger file. Radar translates these complex files into a simple, visual list. You see every part of an API without reading code.
You use this tool to test requests, view data structures, and understand how applications exchange information. It removes the guesswork from technical tasks.
Radar works on modern computers. Ensure your system meets these standards for the best experience:
- Operating System: Windows 10 or Windows 11.
- Memory: At least 4 gigabytes of RAM.
- Storage: 200 megabytes of free space.
- Connectivity: A stable internet connection for loading external API definitions.
You do not need to compile code or install heavy environments. Follow these instructions to set up the software on your machine:
- Visit the official download page to access the latest installer.
- Look for the file ending in .exe in the list of assets.
- Click the file to start your download.
- Open the file once the download finishes.
- Follow the prompts in the installation window to place Radar on your computer.
Open the application from your desktop or start menu. You see a clear, blank interface when the program starts.
API developers create files that end in .json or .yaml. These files contain the rules for their services. To add an API to Radar, click the Add button in the top menu. Paste the web link of your API specification or choose a file from your hard drive.
Radar parses the file immediately. You see a list of functions appear on the left side of your screen.
Each entry in the list represents a command the API understands. Click on any name to see the details of that command. You see the type of operation, such as Get, Post, or Delete. You also see the information the server expects for that call.
You test API calls inside the right panel. Radar provides fields for you to input data. Fill in the boxes and press the Send button. The application sends your request to the server and prints the result below.
This view tells you if the server accepts your data. The colors indicate the status. Green means success. Red suggests a problem with your request.
You tailor the look and behavior of Radar through the Settings menu. Access this menu by clicking the gear icon in the top right corner.
- Theme: Choose between a light background or a dark background. Dark mode reduces eye strain during long sessions.
- Proxy Settings: If your office or home network uses a proxy, input the details here. The application needs this information to reach the internet.
- History: Radar saves your recent requests. Clear this list at any time to remove sensitive information from your local storage.
Radar runs locally on your machine. The software does not send your API secrets or test data to a third-party server. All requests originate from your computer to the API you specify. We do not track your usage patterns. Your data stays under your control.
Does the software require a login? No. You jump straight into your work without creating an account or providing an email address.
How do I update the application? The software checks for new versions each time you launch it. If a newer release exists, a notification appears. Click the notification to download the update automatically.
What if the API is secured? Many APIs require a digital key to function. Radar includes an Authorization tab in the testing panel. Select the type of security the API uses, such as a Bearer Token or API Key, and paste your credential. The application includes this key in your headers for you.
Can I save my workspace? Yes. Use the Save Workspace option to create a file containing your current API list. Use this file on another machine or share it with team members.
If you encounter issues, verify the following:
- Invalid File: If the tool rejects your file, check that the file follows the OpenAPI standard. A missing required field in the file causes parsing errors.
- Connection Timeouts: If a request hangs, verify your internet connection. Some APIs limit the number of requests you send in a short time.
- Displays: If the interface looks small or fonts appear blurry, go to your Windows Display Settings and adjust the scaling. Radar works best at 100% or 125% scale.
Restart the software if it becomes unresponsive. This resets the internal engine and clears memory buffers. If problems persist, return to the download page to check for newer releases or known issues reported by the community.
