ABTestingGateway is a layer-7 gray-release (canary) gateway built on nginx and ngx_lua that dynamically routes requests to different upstreams according to diversion policies stored in Redis. Originally part of Sina Weibo's internal dygateway, it supports ip-range, uid-range, uid-tail, and specific-uid splitting, multi-level diversion, and runtime policy changes without restarts.

Use cases

• dynamically split traffic between upstreams without restarting nginx
• run canary releases with policy-based gray deployment
• do A/B testing based on user id, ip range, or uid tail digits
• gradually route a subset of requests to a beta backend
• set up multi-level staged traffic diversion
• implement layer 7 load balancing with near-native nginx performance

When to choose

• You already run nginx/openresty and Redis and need runtime-configurable canary or A/B traffic splitting
• You want diversion rules by ip range, uid range, uid tail, or specific uids that take effect immediately without restarts
• Forwarding performance close to native nginx matters to you
• You want to extend the system with custom Lua-based diversion strategies

When to avoid

• You need an actively maintained gateway - the last release dates to 2018 and it targets older openresty versions with known lua-resty-core compatibility caveats
• Your stack is cloud-native or service-mesh oriented and you would prefer Envoy/Istio or a modern API gateway
• You cannot deploy Redis as the policy database
• You need gRPC or non-HTTP traffic splitting
