Designed with performance in mind

A robust, lightweight, and portable architecture for high throughput with low CPU and memory usage from any data source to any destination.
Scalable}
Scalable

Proven across distributed cloud and container environments. Highly available with I/O handlers to store data for disaster recovery.

> 1pb data throughput across thousands of sources and destinations daily

Flexible}
Flexible

Granular management of data parsing and routing. Filtering and enrichment to optimize security and minimize cost.

> 1 Billion sources managed by Fluent Bit - from IoT Devices to Windows and Linux servers.

Efficient}
Efficient

Lightweight, asynchronous design optimizes resource usage: CPU, memory, disk I/O, network. No more OOM errors!

~ 450kb minimal footprint maximizes asset support. Zero external dependencies.

Extensible}
Extensible

Integration with all your technology - cloud native services, containers, streaming processors, and data backends.

80+ Plugins for inputs, filters, analytics tools and outputs.

Fluent Bit is a CNCF (Cloud Native Computing Foundation) graduated project under the umbrella of Fluentd.

We are part of a large open source community. No vendor lock-in.

The Fluent Bit Advantage

Fluent Bit is purpose built for high scale data observability in any dynamic, distributed environment
Event-Driven Architecture
Event-Driven Architecture

Fully event driven design, leverages the operating system API for performance and reliability. All operations to collect and deliver data are asynchronous

Dynamic Routing
Dynamic Routing

Optimized data parsing and routing to improve security and reduce overall cost. Distribute data to multiple destinations with a zero copy strategy

Flexible Configuration
Flexible Configuration

Simple, granular controls enable detailed orchestration and management of data collection and transfer across your entire ecosystem

Robust I/O Handler
Robust I/O Handler

An abstracted I/O layer supports high-scale read/write operations and enables optimized data routing and support for stream processing

Upstream Manager
Upstream Manager

Removes challenges with handling TCP connections to upstream data sources. Simplifies connection process, manages timeout/network exceptions and Keepalived states

Security & TLS
Security & TLS

When delivering data to destinations, output connectors inherit full TLS capabilities in an abstracted way. Add your certificates as required.
