overview
TCP proxy to simulate network & system conditions for chaos & resiliency testing
history
Toxiproxy is Shopify's TCP proxy for simulating network conditions in tests, CI, and development. It lets applications route connections through a local proxy and then apply deterministic or randomized failures such as latency, bandwidth limits, timeouts, packet loss, resets, and disabled links.
Shopify created Toxiproxy during its 2014 resiliency work, when the infrastructure team needed automated ways to test behavior under slow or unavailable dependencies before the holiday traffic season. The official README says Shopify had been using it in all development and test environments since October 2014.
The first public GitHub release, v1.0.0, was published in January 2015 as 'Public Release'. The project later moved through a 2.x line with a Go TCP proxy server, HTTP API, command-line client, metrics documentation, and multiple client libraries.
Toxiproxy spread because it packaged a distributed-systems testing trick into a repeatable developer tool. Instead of requiring root-only Linux networking tools such as tc or iptables, developers could install a user-space proxy, declare upstream services, and manipulate faults from tests through HTTP or client libraries.
The official README lists clients for Ruby, Go, Python, .NET, PHP, Node.js, Java, Haskell, Rust, and Elixir. Homebrew, MacPorts, Nix, and Fedora packaging in the source facts show it being distributed as a standalone CLI/server tool rather than just as a Ruby testing helper.
A typical test setup starts `toxiproxy-server`, populates proxy definitions for dependencies such as Redis or MySQL, points the application at the proxy listen ports, and uses a client or `toxiproxy-cli` to apply toxics around a test case.
The README's Rails example demonstrates taking down Redis or adding latency to MySQL to verify fallback behavior. The same model applies to any TCP dependency, which is why Toxiproxy fits CI and local development better than manually editing host networking rules.
For package nerds, Toxiproxy is a high-signal example of infrastructure testing becoming a simple package install. It turns failure injection into `brew install toxiproxy`, a server process, and a CLI/API surface that can be scripted from test suites.
It also helped normalize resilience testing in ordinary application repositories: package maintainers and application developers could add fault-injection checks without privileged networking setup or specialized chaos-testing platforms.
