The control plane: free or dedicated
Kapsule Mutualized is free. This control plane offers up to 4 GB of memory, one replica and 150 nodes, with no SLA. Dedicated offers move to two replicas with a 99.5% SLA, and Scaleway aims them at heavy workloads and business-critical applications. The mutualized plane often fits a development environment, less so a service that needs an availability commitment. In Paris, Scaleway lists:
- Kapsule Dedicated-4: €0.11 per hour, about €80.30 per month, 250 nodes.
- Kapsule Dedicated-8: €0.18 per hour, about €131.40 per month, 500 nodes.
- Kapsule Dedicated-16: €0.35 per hour, about €255.50 per month, 500 nodes.
Nodes, volumes and load balancers
Scaleway bills nodes at the price of the underlying Instances. In zone PAR-1, a POP2-4C-16G costs €0.147 per hour, about €107.31 per month. A BASIC3-X4C-16G, with the same 4 vCPUs and 16 GB, costs €0.11845 per hour, about €86.46 per month. The choice of type therefore carries real weight. Three POP2-4C-16G nodes come to about €321.93 per month. Kapsule Dedicated-4 would add about €80.30, roughly 25% more. This calculation from list prices leaves out volumes and load balancers.
Load balancers and persistent volumes are billed separately. Scaleway includes egress and IPv6 in its Instance prices, and leaves out storage and attached public IPv4 addresses. Count this line if you compare Kapsule with another provider.
What Onicost counts on Kapsule
Onicost reads the public Scaleway catalog, in euros, for Instance types and the volumes of the CSI driver. If your organization works in euros, no conversion takes place. It groups nodes by Kapsule pool and splits their cost between workloads, system and unused capacity. The node table sets capacity, requested and used resources next to each estimated cost. Each volume goes to the workload that mounts it, and a volume no pod has mounted for 7 days becomes a recommendation.
Two lines need your attention. Onicost uses the mutualized control plane: a dedicated offer stays at €0 in its Kubernetes costs, and you add that amount yourself. Load balancers and IPv4 addresses also stay out of these costs. Connect the Scaleway account and the Cloud space reads your bill, finds the Kapsule nodes and compares their estimated cost with the billed cost.
The levers left on Kapsule
The public Scaleway catalog lists no Spot price as of November 6, 2026. Onicost therefore proposes no move to Spot on Kapsule. Your levers are requests, the number of nodes in a pool and the Instance type. Onicost simulates the placement of the pods of each pool to estimate these gains, which you then check on your bill. A stopped pod does not remove its node: freed nodes leave only if the pool autoscales. On an autoscaled pool, Onicost flags a minimum that blocks the drop, as long as the Scaleway account is connected.
A development pool can also stop at night. With Team, the scheduler empties the Kapsule pool at the planned time and restores its size and bounds at the restart, through a dedicated write identity that you create. Scaleway Savings Plans quote up to 25% off monthly compute. Scaleway does not expose purchased commitments through its API, so Onicost cannot see them. The global discount lets you account for them if Scaleway is your only provider.
Your cost data stays in France
Kapsule is available in Paris, Amsterdam, Warsaw and Milan. Onicost data stays in France, in the Scaleway Paris region, for 13 months. Your cluster and your FinOps tool can therefore stay with the same European provider. This hosting does not replace your own compliance review.
The agent sends the inventory and the usage. It collects no Secrets, ConfigMaps, logs or application data. To send less, exclude.namespaces drops whole namespaces and exclude.labelKeys removes label keys before sending.
Install the agent on Kapsule
The kubelet certificate on Kapsule does not hold the IP address of the node. The agent then verifies it against the node name. If its logs still show a tls_verification error, set kubelet.apiServerProxy=true. This option adds the nodes/proxy permission, which opens the whole kubelet API, pod logs included. Keep it for that case.
Free includes one cluster up to 32 cores and 2 members. Team costs from €39 per month before tax, and you can try it for 14 days without a card. Your cloud spend adds no percentage to the price of Onicost. All these amounts stay estimates, and a saving is never guaranteed.
Frequently asked questions
Is the Kapsule control plane free?
Yes for Kapsule Mutualized. Dedicated offers cost €0.11 to €0.35 per hour in Paris. Onicost does not read this choice, so add that amount to its estimates.
Why does Onicost not propose Spot on Kapsule?
It reads the public Scaleway catalog, which lists no Spot price as of November 6, 2026. The Move to spot recommendation needs a Spot price to put a number on a gain.
Do I need to connect my Scaleway account?
The Helm chart is enough for Kubernetes costs. With Team, the Scaleway account adds your bill, load balancers and scheduled pool stops.
