GravityKit
GravityKit folds every GravityView extension into one Pro plugin.
A side-by-side editorial comparison of Porter and CircleCI — release velocity, themes, recent moves, and the top alternatives to consider.
Porter tightens its security layer with short-lived cloud credentials and zero-trust workload access.
Porter is a Kubernetes-based PaaS targeting engineering teams that want AWS/GCP infrastructure without managing raw k8s. Over the past year it has added GPU job support, temporal-based autoscaling, multiple node groups, and overhauled both application creation and datastore management flows. The most recent release focuses squarely on access control: short-lived cloud credentials and secure cloud access for workloads indicate a move toward zero-trust IAM patterns at the infrastructure level.
CircleCI's SSH reruns now open from the browser, through one trusted address.
CircleCI is tidying both ends of the pipeline before December. Config warnings become hard failures on December 14, and the v1 project APIs lose their branches field on December 7 after brownouts on November 17 and December 1. On November 12 Rerun job with SSH moved to a single host, ssh.circleci.com, on ports 22 or 443 with fixed IPs, plus a terminal that opens from the job page. Functions, versioned job-setup programs agents can configure, entered beta on November 4.

Porter is building a security and compliance layer on top of its deployment primitives — audit logs appear twice across these entries, SOC 2 controls via Drata, short-lived credentials, and workload identity. In parallel, AI-adjacent features have appeared at each release cycle: DeepSeek-R1 model deployment, a Helicone observability add-on, GPU time-slicing, and full GPU Jobs. The two tracks — security hardening and AI infrastructure — are converging toward a production-ready positioning for AI workloads.
The next release will likely push deeper on IAM: workload-level RBAC and service account policies are the logical follow-on to short-lived credentials. Expanded GPU options for training (not just inference) jobs are probable given the incremental progression from time-slicing to full GPU Jobs.

CircleCI is closing old paths (lenient config, v1 API fields, old Xcode images) while making failures easier to reach: job-linked commit statuses last week, browser SSH this week. The newer Functions beta and API v3 are where users are being steered.
Expect more debug tools on the job page and further v1 API removals pointing users to v3 before year end.
