logxide 0.1.18

Fastest Python logging library — Rust-powered, stdlib-compatible API

LogXide

2.7x faster Python logging, powered by Rust.

Same stdlib API. Same getLogger. Same format strings. Just faster.

# Before                              # After
import logging                        from logxide import logging

logging.basicConfig(level=logging.INFO)
logger = logging.getLogger('myapp')
logger.info('Hello, world!')          # 2.7x faster. Same code.

Installation

pip install logxide

# With Sentry integration
pip install logxide[sentry]

Performance

Real-world file logging benchmarks (Python 3.12, 100K iterations):

Scenario	LogXide	Picologging (C)	stdlib logging	vs Pico	vs stdlib
Simple	446,135 ops/s	372,020 ops/s	157,220 ops/s	+20%	+184%
Structured	412,235 ops/s	357,193 ops/s	153,547 ops/s	+15%	+168%
Error	426,294 ops/s	361,053 ops/s	155,332 ops/s	+18%	+174%

20% faster than Picologging (C-based, Microsoft). 2.7x faster than stdlib. Full benchmarks →

Works With

LogXide intercepts stdlib logging — most libraries work without changes.

Framework / Library	Status	Notes
Flask	✅	app.logger automatically intercepted
Django	✅	LOGGING dictConfig supported
FastAPI / Uvicorn	✅	All uvicorn loggers intercepted
SQLAlchemy	✅	SQL query logging via echo=True
requests / httpx	✅	HTTP connection logs captured
boto3 / botocore	✅	AWS SDK logs captured
Sentry	✅	Native integration — auto-detects SDK
Celery	⚠️	Requires setup_logging signal (guide)
pytest	⚠️	Use caplog_logxide instead of caplog

Built-in Sentry Integration

No extra handlers. No configuration. Just works.

import sentry_sdk
sentry_sdk.init(dsn="your-dsn")

from logxide import logging

logger = logging.getLogger(__name__)
logger.error("This is automatically sent to Sentry")

• Auto-detects Sentry SDK
• WARNING+ sent as events, INFO as breadcrumbs
• Full stack traces and custom context

Native OpenTelemetry Support

Ship logs to any OTLP-compatible backend with zero dependencies:

from logxide import OTLPHandler

handler = OTLPHandler(
    url="http://localhost:4318/v1/logs",
    service_name="my-service"
)

Quick Start

from logxide import logging

# Basic setup — same API as stdlib
logging.basicConfig(
    level=logging.INFO,
    format='%(asctime)s - %(name)s - %(levelname)s - %(message)s'
)

logger = logging.getLogger('myapp')
logger.info('Hello from LogXide!')
logger.warning('This works exactly like stdlib logging')

Custom fields with extra

logger.info("User logged in", extra={
    "user_id": 12345,
    "ip": "192.168.1.1",
    "metadata": {"browser": "Chrome", "version": 120}
})

HTTP log shipping

from logxide import HTTPHandler

handler = HTTPHandler(
    url="https://logs.example.com",
    global_context={"app": "myapp", "env": "production"},
    transform_callback=lambda records: {
        "logs": [{"msg": r["msg"], "level": r["levelname"]} for r in records]
    }
)

What's Different from stdlib

LogXide reimplements Python's logging in Rust for speed. The API is the same, but some advanced stdlib patterns aren't supported:

Feature	Status
getLogger, info, debug, warning, error, critical	✅ Same API
basicConfig, format strings, levels, filters	✅ Same API
FileHandler, StreamHandler, RotatingFileHandler	✅ Rust-native
HTTPHandler, OTLPHandler	✅ Rust-native, high throughput
Custom Python handlers via addHandler()	⚠️ Works, but bypasses Rust pipeline
Subclassing LogRecord or Logger	❌ Rust types, not subclassable
pytest caplog fixture	⚠️ Use caplog_logxide instead

Instead of subclassing LogRecord, use extra={} for custom fields, global_context for metadata, or transform_callback for output transformation.
