Chihaya is an open source BitTorrent tracker written in Go.

Differentiating features include:

  • HTTP and UDP protocols
  • IPv4 and IPv6 support
  • Pre/Post middleware hooks
  • YAML configuration
  • Metrics via Prometheus
  • High Availability via Redis
  • Kubernetes deployment via Helm

Note: The master branch may be in an unstable or even broken state during development. Please use releases instead of the master branch in order to get stable binaries.

Why Chihaya?

Chihaya is built for developers looking to integrate BitTorrent into a preexisting production environment. Chihaya's pluggable architecture and middleware framework offers a simple and flexible integration point that abstracts the BitTorrent tracker protocols. The most common use case for Chihaya is enabling peer-to-peer cloud software deployments.



Long-term discussion and bug reports are maintained via GitHub Issues. Code review is done via GitHub Pull Requests. Real-time discussion is done via freenode IRC.

Getting Started

Building from HEAD

In order to compile the project, the latest stable version of Go and knowledge of a working Go environment are required.

git clone
cd chihaya
go build ./cmd/chihaya
./chihaya --help


Docker containers are available for HEAD and stable releases.


The following will run all tests and benchmarks. Removing -bench will just run unit tests.

go test -bench $(go list ./...)

The Chihaya executable contains a command to end-to-end test a BitTorrent tracker. See

chihaya --help


Configuration of Chihaya is done via one YAML configuration file. The dist/ directory contains an example configuration file. Files and directories under docs/ contain detailed information about configuring middleware, storage implementations, architecture etc.
