The first client agent is usually easy to host. The second one is manageable too. Then the operational questions arrive: an update needs to land, a workflow must still be available on Monday morning, a client asks where their data is hosted, or an outage has to be explained before it becomes a trust problem.
That is why the real cost of hosting n8n or an AI agent is not the headline price of a VPS. It is the ongoing work around the server.
A server price is not the full cost of a client service
A small server is a sensible place to prototype. Install the workflow tool or agent, add secrets, and see whether the outcome is useful. But a recurring service for several client businesses also needs a repeatable answer for:
- keeping client workloads separate;
- applying updates and recovering from failures;
- handling access and API keys;
- communicating availability to people who did not buy a server;
- explaining European hosting and data residency clearly.
None of that appears as a separate VPS line item. It does appear in support time, interrupted delivery work and a margin that becomes harder to predict as the client list grows.
Keep the operating unit understandable
The useful operating unit is simple: one client agent, one isolated runtime, and a clear owner for the customer relationship. The Integrator keeps the offer, onboarding and invoice; the infrastructure should make that service easier to run rather than create another control panel to manage.
Navlet’s dedicated runtime costs €9 per deployed agent per month when you bring your own LLM key. A European-model-included tier starts at €29 per deployed agent per month. Both include 2 vCPU, 4 GB RAM and 6 GB disk.
This does not hide the model cost. On the BYOK tier, the Integrator chooses its model provider and uses its own API key. It can then price the client service around the outcome, support and onboarding it provides.
Test the service before making it the default
Infrastructure is easier to evaluate with a real pilot: one agent, one client and the access expectations of a production service. Navlet offers €1 in starter credit with no card required so that first deployment can be tested without turning a technical experiment into a procurement exercise.
Additional capacity remains explicit: €0.80 per vCPU, €0.70 per GB of RAM and €0.09 per GB of disk, per month.
The cost worth optimising is the one you can explain
The lowest visible monthly number is not always the cheapest service to operate. A sustainable choice lets you answer where the agent runs, who can access it, how clients stay separated and what happens when something needs attention.
When those answers are straightforward, infrastructure stops being invisible operational overhead for the Integrator. It becomes a dependable part of the service your clients buy from you.
