Pricing

# Simple pricing. Sovereign economics.

One flat platform price. Usage above your allocation is billed at base rates plus metered transparent cost plus, and the rate card is published before anything is billed, never discovered on an invoice. And you can always self-host Kilter or move to another Miniscaler, which is exactly why we can't afford to get greedy.

Enterprise

## Agentic Enterprise

**Custom**

To deploy agentic workflows, agents, and applications safely across your organization, book a call with our Enterprise Solutions team.

**Allows** provably safe and secure agentic workflows.

-   Everything in Engineering
-   Kilter Desktop enterprise tiers
-   Dedicated Enterprise Solutions team
-   Integration with production k8s pipelines

For organizations beyond ~10 people, or regulated environments.

All plans come with

-   Ephemeral PR environments: full resources for 4h, then scale-to-zero, reaped at 48h
-   Policy management: guardrails on what apps and agents can do
-   Security: per-app isolation via Kubernetes namespaces, network policy, and managed secrets

Add-ons

## Additional modules.

### Kilter Desktop

Cowork AI for every seat

from $20 / user

Kilter Business Portal becomes Kilter Desktop.

-   A dashboard where business users reach their applications in a portal-friendly way
-   Single sign-on across every agentic-layer app
-   Secure, controlled deployment of business-user-created apps
-   Data access contracts tied to role-based access control (RBAC)
-   Application classification for agentic GRC

### Kilter Studio

Build and deploy Kilter apps

$40 / user + commit

### Airbender ARC

Agentic governance

from $10 / user

The Agentic Rail Controller. Get unreliable agents reliably into production. Runtime guardrails, mitigations, and compliance controls at the application and workflow layer, so your agents don't have to be always right to be safe.

-   KPIs and Critical Control Points create process safety at the system level
-   Agents can be evolved in production
-   A/B test new models or smaller models
-   Kilter application layer ensures human accountability
-   Temporal durable execution ensures consistent execution
-   Role-based access control at agent and namespace levels ensures full control and security at the infrastructure level
-   The Airbender runtime proxy isolates an application when it performs poorly: all LLM and data access is cut off and the application is notified of the mitigation

### Kilter Artifact Manager

Agentic artifacts: docs, designs, miniapps

Volume-based

Priced on storage and bandwidth.

Published rates

## Full sovereign AI capability at 20% of the cost of hyperscalers.

Billed at base rates plus metered transparent cost plus. The rate card is published before anything is billed. Compute, memory, storage, egress: same rule, no category games, no bundle mysteries.

Why can you trust that? Because Kilter is portable and its source is available. If we ever got greedy, you'd self-host, or take your apps to another Miniscaler running the same stack. That isn't a bug in our business model. _It's the enforcement mechanism._

| Resource | Unit | Reference cost |
| --- | --- | --- |
| vCPU | per vCPU-hour | $0.012 |
| Memory | per GB-hour | $0.005 |
| Storage | per GB-month | $0.08 |
| Egress | per GB | $0.01 |

Illustrative reference rates. Your live, binding rate card is always in your portal before anything is billed.

FAQ

## Questions, answered.

What happens after the 14 days?

Your trial converts to the $100/month Engineering plan, or it doesn't, and your environment winds down. No card is required to start, so nothing converts silently. We email you before the trial ends.

How is overage measured and billed?

Per-app resource consumption (CPU, memory, storage, egress) is metered on the platform and billed monthly at base rates plus metered transparent cost plus. The rate card is published before anything is billed, so you'll never discover a rate on an invoice.

What does "production-lite" mean?

An always-on app with modest resource allocations. It never sleeps, unlike free-tier apps, but it isn't sized for heavy production traffic. Perfect for internal tools, dashboards, and departmental apps that need to answer instantly.

Can I self-host instead?

Yes, that's the point. Kilter's source is available today, and everything it provisions is standard Kubernetes. Self-host it, or run on any Miniscaler in the network. Our pricing has to stay honest because leaving is easy.

How are Kilter Desktop seats counted?

Per active user per month, from $20/user: Cowork AI for every seat. Kilter Business Portal becomes Kilter Desktop. Enterprise tiers add governance, audit, and SSO.
