HTTP inspection library for viewing requests and responses, including headers and bodies, with features for logging customization, request-response overriding, and a UI for log viewing.
[!CAUTION] This library is not stable, and the API may change. It is not advised to use it in production projects.
Inspektor is an HTTP inspection library for Ktor. It allows you to view HTTP requests and responses, including basic information, headers, and bodies. Please note that this library is not stable, and the API may change. Users are not advised to use it in production projects.
Here's an introductory article for those who are interested.
Add the following dependency to your build.gradle.kts file:
dependencies {
implementation("com.gyanoba.inspektor:inspektor:latest-version")
}
To use Inspektor, install the plugin in your HttpClient configuration:
// For Android this is enough
val client = HttpClient {
install(Inspektor)
}
suspend fun apiCall() {
client.get("http://example.com")
}
For ios you need to add the following -lsqlite3 to the Other Linker flags under Build Settings.
See more details here
For Desktop platforms, you need to specify the APPLICATION_ID using setApplicationId before using
Inspektor.
This is used to determine the location to store the database file.
fun main() {
setApplicationId("com.example.myapp")
// ...
}
You can customize Inspektor using the InspektorConfig object. Here are the available options:
install(Inspektor) {
level = LogLevel.HEADERS
maxContentLength = 100_000
filter { request -> request.url.host.contains("example.com") }
sanitizeHeader { header -> header == "Authorization" }
showNotifications = true
retentionDuration = 30.days
}
This feature is meant to be used for testing purposes. It allows you to override the request and response bodies. To use this feature, open the overrides page from the menu. Add new overrides by specifying matchers for the request; then select the action to perform, i.e. override the request or response. Only the values specified are replaced in the request or response. Empty values are ignored.

You can easily add new overrides by clicking on the Edit icon in the Transactions List screen. Default override with original info gets created which you can then modify to get your desired result.
Inspektor provides a UI to view the logs. You can access it by invoking openInspektor function.
This opens up a new activity in Android, a bottom sheet in iOS, and a new window in the Desktop.
On Android you can also open the UI by clicking on the generated notifications.
Inspektor supports exporting the logs in HAR format. You can export the logs by clicking on the "Export as HAR" button in the UI. This allows you to analyze the logs in detail using tools like HAR Viewer or Fiddler.
