Use pipes to create elegant streaming programs within Haskell. Build streaming components and connect them them together to process both events and data.
Libraries
Pipes is the official Hackage category for the pipes ecosystem.
pipes
The pipes package is the core library which emphasizes:
- Elegance and Simplicity
- Speed
- Lightweight dependencies
The pipes library offers many unique features not available in other streaming libraries:
- Bidirectional streams
- Extension framework
- Elegant ListT interconversions
- Correctness proofs for the entire library
Read the official pipes tutorial to learn more.
Source code hosted on GitHub
pipes-safe
The pipes-safe package adds resource management and exception safety to the pipes ecosystem. pipes-safe offers many high-level features such as:
- Complete exception safety, including asynchronous exceptions
- Termination safety
- Resources are freed in reverse order of acquisition
Additionally, pipes-safe is the only streaming library that provides truly native exception handling, allowing you to seamlessly handle exceptions and resume uninterrupted streaming.
Read the official pipes-safe tutorial to learn more.

pipes-concurrency
The pipes-concurrency package adds powerful and light-weight concurrency primitives to the pipes ecosystem. Use these primitives to:
- Build reactive event-driven programs
- Merge and split streams
- Communicate between multiple concurrent pipelines
- Manage multiple resources simultaneously
The pipes-concurrency library offers several features unavailable in other streaming libraries such as:
- Deadlock safety
- Cyclic communication graphs
- Dynamically changing graph topologies
Read the official pipes-concurrency tutorial to learn more.
Source code hosted on GitHub
pipes-parse
The pipes-parse package defines the generic machinery necessary for common parsing tasks using pipes:
- Detect and handle end of input
- Save unused input for later steps
- Mix proxies with different leftover buffers using lenses
- Nesting and delimiting parsers to a subset of the input
- Interruptible and resumable parsing
Read the official pipes-parse tutorial to learn more.

Community-contributed libraries
Listed in alphabetical order.
pipes-aeson
The pipes-aeson library allows you to encode and decode JSON values flowing through streams, possibly interleaving other stream effects while doing it.
Source code is hosted on GitHub
pipes-attoparsec
The pipes-attoparsec library converts attoparsec parsers to pipes for high-performance incremental parsing.
Source code hosted on GitHub
pipes-binary
The pipes-binary library allows streams of binary data to be encoded and decoded using the Binary
instances from the binary package.
Source code is hosted on GitHub
pipes-network
The pipes-network library converts server and client sockets to pipes to seamlessly stream data over any network.
Source code hosted on GitHub
pipes-network-tls
The pipes-network-tls allows streaming through TLS-secured network connections, exposing a similar API to the one exposed by pipes-network.
Source code hosted on GitHub
pipes-zlib
The pipes-zlib enables compression and decompression of strict ByteString streams using the zlib codec.

Community
Besides the usual Haskell community channels such as the official mailing lists or the Haskell subreddit, you can ask for help, suggest improvements, or discuss about the Pipes ecosystem at the “haskell-pipes” mailing list at Google Groups.
