HAProxy Kubernetes Ingress Controller vs Scalar

HAProxy Kubernetes Ingress Controller vs Scalar: at a glance
What is HAProxy Kubernetes Ingress Controller?
Nineteen patches into 3.2, HAProxy's ingress controller is mostly bumping dependencies
The controller remains on the 3.2 patch line. Since v3.2.14 the only release of substance is v3.2.15, which stopped filtering ingresses on IngressClass name at ingestion, reworked status publishing and moved to Go 1.27. Later patches are mainly dependency and tooling updates, with v3.2.18 keeping every TLS secret of an ingress on the same host and v3.2.19 fixing a data race on the reload flag.

What is Scalar?
Scalar is testing demand for hosting from inside localhost
The October 1.76 run put a sticky developer toolbar above the API reference on localhost, with Configure, Share, Deploy and Generate SDK tools in a side panel. The Deploy tool now shows a waitlist for API hosting on Scalar, and 1.76.4 records the server framework with each sign-up. AsyncAPI rendering kept improving, with binding schemas shown as structured properties. In another package line, 0.20.0 moved to Undici 8 with HTTP/2 on by default and raised the minimum Node.js version to 22.19.0.

Nineteen patches into 3.2, HAProxy's ingress controller is mostly bumping dependencies
◆ Current state
The controller remains on the 3.2 patch line. Since v3.2.14 the only release of substance is v3.2.15, which stopped filtering ingresses on IngressClass name at ingestion, reworked status publishing and moved to Go 1.27. Later patches are mainly dependency and tooling updates, with v3.2.18 keeping every TLS secret of an ingress on the same host and v3.2.19 fixing a data race on the reload flag.
◆ Where it's heading
The ssl-passthrough theme has faded, and the series is now closer to routine upkeep than stabilization. Fixes have moved to ingress class handling, TLS secret storage and concurrency, with test coverage arriving in the same changes. Patches keep coming, but no new configuration surface has appeared on this line in the entries shown, apart from amending the SSL frontend through a custom resource in v3.2.15.
◆ Prediction
Expect further patches dominated by go.mod and Kubernetes client updates, with new capability waiting for a later line.
Scalar

Scalar is testing demand for hosting from inside localhost
◆ Current state
The October 1.76 run put a sticky developer toolbar above the API reference on localhost, with Configure, Share, Deploy and Generate SDK tools in a side panel. The Deploy tool now shows a waitlist for API hosting on Scalar, and 1.76.4 records the server framework with each sign-up. AsyncAPI rendering kept improving, with binding schemas shown as structured properties. In another package line, 0.20.0 moved to Undici 8 with HTTP/2 on by default and raised the minimum Node.js version to 22.19.0.
◆ Where it's heading
The reference is becoming a dev-time workbench, not only a published page. Tools that sat in dropdowns moved to a persistent panel, and SDK generation was consolidated there. The hosting waitlist is the commercial signal: Scalar is collecting framework data from developers at the moment they run their API locally, which gives it a demand measure before committing to a deployment flow. AsyncAPI work remains the other steady investment.
◆ Prediction
Expect the waitlist to turn into a hosting beta, with the first supported frameworks chosen from the data 1.76.4 collects; FastAPI, Hono and Express are already named for detection. The monorepo's patch cadence should otherwise continue daily or near it.
