Flask API monitoring & analytics
Flask stays out of your way, which means observability is opt-in. Beacon's init_flask wires request/teardown hooks once at startup and captures every view by its URL-rule template (/users/<int:user_id>) — so traffic, latency percentiles, and errors aggregate per endpoint instead of per concrete path.
100,000 requests per month on the free tier — no credit card to start.
Add Beacon to Flask in two steps
Drop-in middleware. The SDK defaults to Beacon's hosted ingest endpoint, so you only need a
project ingest key — set it as BEACON_INGEST_KEY in your environment.
pip install "beaconhq[flask]"
import os
from flask import Flask
from beaconhq import BeaconClient
from beaconhq.integrations.flask import init_flask
beacon = BeaconClient(ingest_key=os.environ["BEACON_INGEST_KEY"])
app = Flask(__name__)
init_flask(app, beacon)
@app.route("/users/<int:user_id>")
def get_user(user_id):
return {"id": user_id}
Create a project in the dashboard to get your ingest key, then deploy. Traffic, latency, errors, and endpoints populate in real time. Full setup in the docs.
Everything you need to keep your Flask API healthy
One place for traffic, latency, errors, uptime, and scheduled-job health — built for teams who need to know what their API is doing right now.
Traffic & latency percentiles
Per-request volume with p50/p95/p99 latency, so you see real tail latency — not just averages.
Error rates & error explorer
Track 4xx/5xx over time and drill into the exact failing requests, status codes, and endpoints behind an incident.
Endpoint & consumer breakdowns
See which endpoints and which API consumers drive your traffic, errors, and slowest responses — ranked and filterable.
Request-log explorer
A searchable log of individual requests — method, path, status, latency, consumer — the fast path from a metric spike to the requests behind it.
Uptime, cron & heartbeat monitoring
Synthetic uptime checks plus dead-man's-switch heartbeat monitoring for cron jobs and background workers.
Status pages & alerts
Public status pages and multi-channel alerts — email, Slack, PagerDuty, Discord, Teams, and signed webhooks — when something breaks.
