Getting Started

Set up your first feature flag in FlagTGL in under 5 minutes.

1. Create an Account​

Sign up at flagtgl.com/signup or self-host using Docker:

git clone https://github.com/anchoo2kewl/flagtgl.git
cd flagtgl
docker compose up -d

The dashboard will be available at http://localhost:8080.

2. Create an Organization & Project​

After signing in, create an organization and your first project. Each project comes with default environments: Production, Staging, and Development.

3. Create a Feature Flag​

  1. Navigate to your project
  2. Click Create Flag
  3. Enter a key (e.g., new-checkout-flow) and choose Boolean type
  4. The flag is created off by default in all environments

4. Install an SDK​

Go Server SDK​

go get github.com/anchoo2kewl/flagtgl/sdks/go-server-sdk
package main

import (
    "fmt"
    flagtgl "github.com/anchoo2kewl/flagtgl/sdks/go-server-sdk"
)

func main() {
    client, err := flagtgl.NewClient(flagtgl.Config{
        SDKKey:  "your-sdk-key",
        BaseURL: "https://flagtgl.com",
    })
    if err != nil {
        panic(err)
    }
    defer client.Close()

    enabled := client.BoolVariation("new-checkout-flow", flagtgl.User{Key: "user-123"}, false)
    fmt.Println("Feature enabled:", enabled)
}

JavaScript Client SDK​

npm install @flagtgl/js-client-sdk
import { FlagTGLClient } from '@flagtgl/js-client-sdk';

const client = new FlagTGLClient({
  sdkKey: 'your-client-sdk-key',
  baseUrl: 'https://flagtgl.com',
});

await client.waitForInitialization();

const enabled = client.variation('new-checkout-flow', false);
console.log('Feature enabled:', enabled);

5. Toggle Your Flag​

Go back to the dashboard, navigate to your flag, select the Production environment, and toggle it on. Your application will receive the update in real-time via SSE.
