What is NGINX?

NGINX 1.31.5 ships a native control API, JSON module, and predicate locations — NGINX Plus features in open source.

NGINX's mainline branch is moving quickly on native capability expansion. The 1.31.5 release adds three features that were previously exclusive to NGINX Plus or third-party modules: a runtime control API, a built-in JSON parser module, and predicate-based location matching. This follows 1.31.4 adding JSON serialization and data model libraries, and 1.31.3 patching three CVEs including memory corruption in the map module and a use-after-free in SSI.

What is Skipper?

Skipper adds Redis as a distributed L2 cache backend amid a high-frequency patch cadence.

Skipper is running in a maintenance-heavy patch cycle, shipping multiple versions per week focused on stability, test infrastructure, and minor performance work. The architectural addition this period is v0.27.92's Redis L2 storage for the cache() filter, which extends caching from node-local to cluster-shared. v0.27.95's parsed filter and predicate caching across RouteGroups is a performance improvement but stays within the current architecture.

NGINX 1.31.5 ships a native control API, JSON module, and predicate locations — NGINX Plus features in open source.

◆ Current state

NGINX's mainline branch is moving quickly on native capability expansion. The 1.31.5 release adds three features that were previously exclusive to NGINX Plus or third-party modules: a runtime control API, a built-in JSON parser module, and predicate-based location matching. This follows 1.31.4 adding JSON serialization and data model libraries, and 1.31.3 patching three CVEs including memory corruption in the map module and a use-after-free in SSI.

◆ Where it's heading

NGINX is actively pulling capabilities from the commercial F5 NGINX stack into the open-source mainline. The control API in particular has been a core NGINX Plus differentiator — it enables runtime reconfiguration without a reload, which is the key operational advantage of the Plus tier. Narrowing that gap signals a shift in F5's NGINX strategy toward openness, likely driven by competitive pressure from Envoy, Traefik, and Caddy.

◆ Prediction

The control API surface will expand across subsequent mainline releases — the 1.31.5 implementation likely covers a narrow initial subset. Rate limiting and upstream management via API are the natural next additions, along with further JSON module maturation.

Skipper adds Redis as a distributed L2 cache backend amid a high-frequency patch cadence.

◆ Current state

Skipper is running in a maintenance-heavy patch cycle, shipping multiple versions per week focused on stability, test infrastructure, and minor performance work. The architectural addition this period is v0.27.92's Redis L2 storage for the cache() filter, which extends caching from node-local to cluster-shared. v0.27.95's parsed filter and predicate caching across RouteGroups is a performance improvement but stays within the current architecture.

◆ Where it's heading

The Redis L2 integration suggests the Skipper team is addressing the multi-replica cache coherence problem that large deployments encounter. If this pattern continues, distributed-state options—persistent rate limiting, distributed circuit breakers using the same Redis client abstraction—are the natural follow-ons. The high patch cadence signals active production deployment rather than feature-driven development.

◆ Prediction

The Redis client abstraction introduced in v0.27.92 will be extended to other stateful filters, particularly rate limiting, given that distributed rate limiting is the most common request for API gateways running at multi-replica scale.
