Porter vs GravityKit: at a glance
What is Porter?
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.
What is GravityKit?
GravityKit folds every GravityView extension into one Pro plugin.
GravityKit ships a weekly Launch Log across its Gravity Forms add-ons, mostly security fixes and small field options. The November 12 release bundles every GravityView extension and layout into one Pro plugin with Live Filters, Connected Views and an Edit Window; the November 13 log adds paid, ranked Featured Tiers, a Pages with this View menu and more security fixes. October's notable items were Visual Merge Tags, AI-built boards and AI-managed calendars.

◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
GravityKit
5.0INFRA · APIS
GravityKit folds every GravityView extension into one Pro plugin.
◆ Current state
GravityKit ships a weekly Launch Log across its Gravity Forms add-ons, mostly security fixes and small field options. The November 12 release bundles every GravityView extension and layout into one Pro plugin with Live Filters, Connected Views and an Edit Window; the November 13 log adds paid, ranked Featured Tiers, a Pages with this View menu and more security fixes. October's notable items were Visual Merge Tags, AI-built boards and AI-managed calendars.
◆ Where it's heading
GravityKit is consolidating a sprawl of separate add-ons into fewer, larger products while steadily adding AI-assistant hooks to individual tools. Paid Featured Tiers suggest the Pro bundle is also a vehicle for listing and directory use cases.
◆ Prediction
Expect the weekly logs to continue with security fixes, and more products to follow GravityView into bundled editions.
