What is Gatekeeper?

Gatekeeper grew a package manager for policies — and a benchmark to prove they are not too slow.

3.22.0-rc.0 in February introduced two CLI subcommands that change how policies are handled rather than what they express: gator policy, a brew-inspired tool for discovering, installing, upgrading and uninstalling policies from the gatekeeper-library, and gator bench, which benchmarks Rego and CEL engines with latency percentiles, throughput, memory profiling and baseline comparison for CI regression detection. The same release enabled sync-vap-enforcement-scope by default and gave both CEL and Rego access to namespace context during admission and audit. Since then, 3.23.0-rc.1 added status resource routing for remote cluster mode, and 3.24.0-beta.0 made generated ValidatingAdmissionPolicy output deterministic to stop a reconcile loop.

What is Hatchet?

Hatchet takes durable tasks serverless, with handlers for Cloudflare Workers, Vercel and Node.

Hatchet's new @hatchet-dev/serverless 0.1.0 runs tasks on Cloudflare Workers, Vercel and Node. An in-engine operator delivers them by signed POST or by an invocation websocket that also carries durable sleeps, waits and child runs. Around it, the engine shipped three patches in a day: DAG replays no longer take an advisory lock, worker shutdown now waits for durable tasks, and status queries use partition pruning. The API now declares 429 with Retry-After on every authenticated call.

Gatekeeper grew a package manager for policies — and a benchmark to prove they are not too slow.

◆ Current state

3.22.0-rc.0 in February introduced two CLI subcommands that change how policies are handled rather than what they express: gator policy, a brew-inspired tool for discovering, installing, upgrading and uninstalling policies from the gatekeeper-library, and gator bench, which benchmarks Rego and CEL engines with latency percentiles, throughput, memory profiling and baseline comparison for CI regression detection. The same release enabled sync-vap-enforcement-scope by default and gave both CEL and Rego access to namespace context during admission and audit. Since then, 3.23.0-rc.1 added status resource routing for remote cluster mode, and 3.24.0-beta.0 made generated ValidatingAdmissionPolicy output deterministic to stop a reconcile loop.

◆ Where it's heading

The centre of gravity is moving from the admission controller to the tooling around it. Policies are becoming artefacts you install from a library at a version, benchmark against a baseline in CI, and test before they reach a cluster — which is the lifecycle application code already has and policy generally has not. Underneath, the ValidatingAdmissionPolicy path keeps maturing as Gatekeeper hands more enforcement to the Kubernetes-native mechanism it now generates.

◆ Prediction

Remote cluster mode gained status routing but the entries describe only that piece, so how far multi-cluster enforcement extends is unclear from these notes. The releases in this window are all beta and release candidates, so a 3.24.0 stable is the near-term milestone.

Hatchet takes durable tasks serverless, with handlers for Cloudflare Workers, Vercel and Node.

◆ Current state

Hatchet's new @hatchet-dev/serverless 0.1.0 runs tasks on Cloudflare Workers, Vercel and Node. An in-engine operator delivers them by signed POST or by an invocation websocket that also carries durable sleeps, waits and child runs. Around it, the engine shipped three patches in a day: DAG replays no longer take an advisory lock, worker shutdown now waits for durable tasks, and status queries use partition pruning. The API now declares 429 with Retry-After on every authenticated call.

◆ Where it's heading

Until now, running Hatchet meant running long-lived workers. The serverless package removes that requirement, so durable execution can run where JavaScript teams already deploy. The engine work points the same way: rate limits declared in the spec, safer worker acks, cheaper status queries. Patch cadence is still very high, often several engine tags a day, and much of it fixes durable-task edge cases.

◆ Prediction

Expect quick 0.1.x serverless releases as early users hit edge cases on each platform, and possibly matching Python handlers. More engine patches on durable-task shutdown and replay are likely.
