Authelia vs Skipper
A side-by-side editorial comparison of Authelia and Skipper — release velocity, themes, recent moves, and the top alternatives to consider.
Authelia vs Skipper: at a glance
What is Authelia?
Authelia ships weekly OIDC patches as v4.39 works through a long conformance backlog
Authelia is in a steady patch release cycle for v4.39, shipping OIDC conformance fixes, proxy integration patches, and storage correctness fixes every few days. Recent releases address edge cases in consent flows (pre-configured consent saved twice, consent redirect status codes), JARM alg-none conformance, Envoy authz path handling, and SMTP IPv6 literal address support.
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.

Authelia ships weekly OIDC patches as v4.39 works through a long conformance backlog
◆ Current state
Authelia is in a steady patch release cycle for v4.39, shipping OIDC conformance fixes, proxy integration patches, and storage correctness fixes every few days. Recent releases address edge cases in consent flows (pre-configured consent saved twice, consent redirect status codes), JARM alg-none conformance, Envoy authz path handling, and SMTP IPv6 literal address support.
◆ Where it's heading
The high frequency of point releases reflects a long tail of OIDC conformance issues surfaced as more client libraries and proxy configurations hit edge cases in production. The v4.39.21 batch was notably large—over 30 fixes covering LDAP stale aliases, storage AAD/HKDF hardening, token regeneration semantics, and pre-compressed asset serving. This is a codebase being actively hardened rather than feature-extended.
◆ Prediction
A v4.40.0 feature release is the logical next milestone; the dense patch cadence in 4.39 typically precedes a feature window. Expect new OIDC profile features or expanded token management based on the storage and JWT work in recent patches.

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.
