import io.tggl.TgglClientOptions;
 
TgglClient client = new TgglClient(TgglClientOptions.builder()
    .apiKey("YOUR_SERVER_API_KEY")
    .build());

3. Evaluate flags

Map<String, Object> context = Map.of("userId", "abc123");
boolean value = client.get(context, "my-feature", false);
 
if (value) {
  // ...
}

Empower product and marketing teams to experiment within safe boundaries set by your engineering team.

Your app is instantly updated when a flag is updated, no need to write code and deploy the new version.

PerformanceAPI or local flag evaluation

A single API call to evaluate all flags

Tggl lets you evaluate all flags in a single round trip to our servers using our robust and highly performant API.

You can also evaluates thousands of users at once by batching all your calls in a single HTTP request.

Local flags evaluation on your backend

Evaluate millions of flags a second locally without making a single API call. You data never sees our servers and you can evaluate flags a millisecond.

As resilient as it can be, if the Tggl API ever goes down, you can still evaluate flags locally based on the last successful sync.

What our clients have to say about us

At Yuno, we were using Amplitude for product analytics and needed a tool to conduct A/B tests. We were able to integrate Tggl extremely fast and could get our first results in days. As a product manager, Tggl had a great impact on the way we work with the tech team.
