Sentry vs Datadog

// Next.js — sentry.client.config.js
import * as Sentry from "@sentry/nextjs";

Sentry.init({
  dsn: process.env.NEXT_PUBLIC_SENTRY_DSN,
  tracesSampleRate: 1.0,
});

// Python / FastAPI
import sentry_sdk
sentry_sdk.init(
    dsn=os.environ["SENTRY_DSN"],
    traces_sample_rate=1.0,
)

const tracer = require('dd-trace').init({
  service: 'my-service',
  env: process.env.NODE_ENV,
  version: process.env.APP_VERSION,
});

// Auto-instrumentation — just init at startup
// Traces, spans, and logs flow automatically
