Flask Tracing

Trace Flask request spans with Judgment.

Flask tracing uses the standard OpenTelemetry Flask instrumentation and routes request spans through Judgment.

uv add judgeval flask opentelemetry-instrumentation-flask

pip install judgeval flask opentelemetry-instrumentation-flask

from flask import Flask, jsonify
from judgeval import Tracer
from opentelemetry.instrumentation.flask import FlaskInstrumentor

Tracer.init(project_name="flask_app")

app = Flask(__name__)
FlaskInstrumentor().instrument_app(app)


@app.get("/hello")
def hello():
    return jsonify({"message": "hello"})
