FastAPI Pulse

Keep an eye on your FastAPI app with one joyful line.

FastAPI Pulse makes monitoring feel natural: drop in add_pulse(app) and you instantly get live dashboards, smart probes, and a CLI that plays nicely with CI/CD. No boilerplate. No config jungle. Just signal.

Two-Breath Install

pip install fastapi-pulse

from fastapi import FastAPI
from fastapi_pulse import add_pulse

app = FastAPI()
add_pulse(app)  # monitor, dashboard, probes – all unlocked

Want the CLI too? pip install "fastapi-pulse[cli]"

Why People Love It

• One-line setup – call add_pulse(app) and ship it.
• Peaceful defaults – zero configuration for the common path.
• Live dashboard – /pulse shows latency, throughput, success rates.
• Probing built-in – discover endpoints and fire health checks from the UI or CLI.
• Production-safe – TDigest percentiles, rolling windows, no memory leaks.

What You Get

Add your own monitors using the JSON API or wire it into your favorite alerting tool—the payload mirrors what the dashboard sees.

Tiny Tweaks When You Need Them

add_pulse(
    app,
    dashboard_path="/pulse",          # move the UI
    enable_detailed_logging=False,    # quiet production logs
    payload_config_path="pulse_probes.json",  # persist probe payloads
)

Prefer a custom metrics window?

from fastapi_pulse import PulseMetrics

metrics = PulseMetrics(window_seconds=600)
add_pulse(app, metrics=metrics)

CLI In Your Pocket

pulse-cli check http://localhost:8000
pulse-cli check https://api.example.com --fail-on-error --format json

Trying the TestPyPI Build

python3 -m venv .venv && source .venv/bin/activate
pip install --upgrade pip
