How much does a CI/CD pipeline actually cost to build

A founder in Tallinn emailed me last month. He had raised a EUR 1.2 million seed round and was trying to budget for infrastructure. His question was simple: “How much does it cost to build a CI/CD pipeline?” His CTO had quoted EUR 40,000 and three months of engineering time. A consulting firm had quoted EUR 25,000. A freelancer on Upwork had quoted EUR 3,500. He wanted to know which number was real.

They were all real. They were just answering different questions, and none of them were answering his.

I have built CI/CD pipelines for 23 companies over the last four years. Seed-stage, Series A, one Series B. Some from scratch on a greenfield cluster. Some replacing manual deploy scripts that had been running for two years. Some as emergency work after a bad deploy took production down for nine hours. The cost is never one number. It is a function of what you already have, what you are willing to do yourself, and what you are pretending you do not need.

I am going to break it down the way I break it down for founders when they ask. Real numbers, real tools, real time. Not a price list. A cost model.

What you are actually building

Before the numbers, the scope. A CI/CD pipeline is not one thing. It is four systems bolted together, and each one has a cost.

The first system is the build pipeline. Something watches your repository, runs your tests, builds an artifact, and stores it. For most startups this is GitHub Actions and GitHub Container Registry. The build pipeline is the part that developers interact with daily. It needs to be fast, reliable, and honest about failures.

The second system is the deployment mechanism. Something takes the artifact and puts it in a running environment. For startups running on Kubernetes, this is ArgoCD or Flux in a GitOps configuration. For startups on a VPS, this could be a simple Docker Compose reload triggered by a webhook. The deployment mechanism is the part that determines whether your deploy is automated or manual, and whether rollback is a button or a nightmare.

The third system is the environment. The cluster or server where your code runs. This is not strictly part of the CI/CD pipeline, but you cannot build a pipeline without it, and its configuration determines what the pipeline needs to do. A Kubernetes cluster with namespaces, ingress, and cert-manager is a different pipeline target than a single Hetzner box with Docker.

The fourth system is the feedback loop. Observability. When the pipeline deploys something, you need to know whether it worked. Not “the pipeline finished successfully.” That tells you the deploy happened. You need to know whether the deployed version is healthy. Prometheus scraping your services, Grafana showing deploy markers and error rates, an alert that fires when error rate spikes after a new revision. Without this, your pipeline is deploying blind.

All four systems have a cost. Most founders only budget for the first two.

The three cost scenarios

Scenario one: you build it yourself

This is the scenario where the founder or an early engineer spends evenings and weekends building the pipeline. No external help. No consultant. Just docs, trial and error, and Stack Overflow.

The cloud costs are the easy part. A GitHub Actions runner is free for 2,000 minutes per month on a private repo, and EUR 0.008 per minute after that. For a startup with 5 engineers pushing 20 commits a day, you will use roughly 600 build minutes per month. You are nowhere near the paid tier. GitHub Container Registry is free for the first 500MB and EUR 0.07 per GB per month after. A startup with 20 images at 200MB each is storing 4GB. That is EUR 0.28 per month. Round it to nothing.

# .github/workflows/ci.yaml
name: ci
on:
  push:
    branches: [main]

jobs:
  build:
    runs-on: ubuntu-latest
    permissions:
      contents: read
      packages: write
    steps:
      - uses: actions/checkout@v4
      - run: npm ci && npm test
      - uses: docker/build-push-action@v6
        with:
          push: true
          tags: ghcr.io/${{ github.repository }}:${{ github.sha }}
          cache-from: type=gha
          cache-to: type=gha,mode=max

The cluster is where money starts to matter. A managed Kubernetes cluster on AWS EKS costs EUR 0.10 per hour for the control plane. That is EUR 73 per month before you have deployed a single pod. Add two t3.medium nodes for the workloads and you are at roughly EUR 130 per month. On Google Cloud GKE Autopilot, the control plane is free and you pay per pod, which for a startup running 8 pods comes to about EUR 60 per month. On Hetzner Cloud with a self-managed cluster using k3s on a EUR 20 CX22 server, you are at EUR 20 per month total. The cluster cost is a function of where you run it, and for a seed-stage startup, the difference between EKS and Hetzner is EUR 100 per month that you do not need to spend yet.

ArgoCD is free. It is open source. You install it in your cluster with a Helm chart and it runs as a workload. The cost is not the software. The cost is the time it takes to learn it.

helm install argocd argo/argo-cd \
  --namespace argocd \
  --create-namespace \
  --set server.service.type=ClusterIP \
  --set server.ingress.enabled=true \
  --set server.ingress.hostname=argocd.example.com

That command takes 30 seconds to run. Understanding what ArgoCD does, how ApplicationSets work, how sync waves order your resources, and how to structure your deploy repository takes two to three weeks of focused work if you have never done it before. That is the real cost.

The observability stack is the same story. Prometheus and Grafana are free. Installing them with kube-prometheus-stack takes one command. Configuring them to scrape your services, building dashboards that actually mean something, and writing alerting rules that fire on real problems instead of noise takes another one to two weeks.

helm install kube-prom-stack prometheus-community/kube-prometheus-stack \
  --namespace monitoring \
  --create-namespace \
  --set grafana.adminPassword=$(openssl rand -base64 24) \
  --set prometheus.prometheusSpec.retention=15d

The total cloud cost for scenario one is roughly EUR 80 to EUR 150 per month depending on your cluster choice. The time cost is 4 to 6 weeks of one engineer’s focused effort. If that engineer is your CTO, that is 4 to 6 weeks where your CTO is not building your product. At a seed-stage startup, that tradeoff is expensive in ways that do not show up in a spreadsheet.

The hidden cost of scenario one is mistakes. A self-taught pipeline built under time pressure will have gaps. No image scanning. No signed artifacts. Alerts that fire on the wrong threshold. A rollback path that works in testing but has never been exercised under pressure. These gaps surface during incidents, and incidents cost more than the time you saved by skipping the consultant.

Scenario two: you hire someone who has done it before

This is the scenario where you bring in a contractor or a consultant who has built CI/CD pipelines before. Not a full-time hire. Someone who comes in for a fixed scope, builds the pipeline, documents it, and leaves.

The cloud costs are the same. EUR 80 to EUR 150 per month. The difference is the labor cost and the timeline.

A competent DevOps contractor in Europe charges EUR 600 to EUR 900 per day. Building a production-grade CI/CD pipeline with GitOps, observability, and runbooks for a startup takes 3 to 4 weeks of focused work. That is 15 to 20 working days. At EUR 700 per day, the midpoint, you are looking at EUR 10,500 to EUR 14,000.

That number buys you a pipeline that works. CI builds and tests on every push. ArgoCD syncs from a deploy repository. Prometheus scrapes your services. Grafana has dashboards for error rate, latency, and deploy markers. Five to seven alerting rules routed to Slack or PagerDuty. Runbooks for the top three failure modes. RBAC scoped per namespace. A documented rollback procedure that has been tested.

# Example ArgoCD Application that a contractor would set up
apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
  name: api
  namespace: argocd
spec:
  source:
    repoURL: https://github.com/yourorg/yourorg-deploy
    path: apps/api/overlays/prod
    targetRevision: HEAD
  destination:
    server: https://kubernetes.default.svc
    namespace: api
  syncPolicy:
    automated:
      prune: true
      selfHeal: true
    syncOptions:
      - CreateNamespace=true

The difference between scenario one and scenario two is not the cloud bill. It is the 4 to 6 weeks of your engineer’s time, replaced by 3 to 4 weeks of someone else’s time. And the difference in quality. Someone who has built 20 pipelines knows which gaps will bite you and closes them before they do. Someone building their first pipeline does not.

The mistake founders make here is comparing the contractor cost to the DIY cost and concluding that DIY is cheaper. It is not. The DIY cost includes the opportunity cost of your engineer not building the product, plus the cost of the gaps that will surface during the first incident. The contractor cost is visible and fixed. The DIY cost is invisible and variable, and it almost always exceeds the contractor cost by the time you account for the first production incident.

Scenario three: you do not build it

This is the scenario most founders do not budget for, and it is the most expensive one.

You do not build a CI/CD pipeline. Your lead engineer deploys with a script. Maybe a Makefile that runs docker build, docker push, and ssh into the server to restart the container. It works. It has always worked. You ship features. Users are happy. Investors are not asking yet.

Then one of three things happens.

The first thing: your lead engineer leaves. They go on vacation, they quit, they get sick. Nobody else knows the deploy script. Nobody else has SSH access to the server. Nobody else knows which environment variables are set where. Production does not deploy for a week. A critical bug fix sits in a pull request while you wait for your engineer to come back. Users complain. You lose a customer. The cost of that lost customer, plus the cost of the emergency contractor you hire to figure out the deploy script, plus the cost of rebuilding the pipeline in a panic, exceeds the cost of having built it properly in the first place.

The second thing: a bad deploy takes down production. The script pushes a new image. The container starts. The health check passes. But the new version has a migration that breaks the database schema. The script has no rollback. Your engineer tries to deploy the old image manually, but the database has already migrated. You are down for 6 hours while you manually repair the database. The cost of those 6 hours, in lost revenue, lost trust, and lost sleep, exceeds the cost of the pipeline that would have caught the migration issue in a staging environment and rolled back automatically.

The third thing: you go into a funding round and the investor asks the deploy question. I wrote about this separately. The answer “we have a script” costs you 15% of your valuation. On a EUR 14 million pre-money, that is EUR 2.1 million. The pipeline that would have prevented that loss costs EUR 14,000. The ratio is 150 to 1.

Scenario three is the scenario most startups are in. They do not know it because the cost has not arrived yet. It is deferred, accumulating, and it will arrive at the worst possible moment.

The cost breakdown table

Here is the way I present it to founders. A table, with the three scenarios side by side.

The cloud costs are EUR 80 to EUR 150 per month in all three scenarios. If you are in scenario three, you are still paying for the server. You just are not paying for the pipeline that would use it well.

The labor cost in scenario one is EUR 0 in cash but 4 to 6 weeks of engineer time. At a seed-stage startup where your engineer’s fully loaded cost is roughly EUR 8,000 per month, that is EUR 8,000 to EUR 12,000 in opportunity cost. In scenario two, the labor cost is EUR 10,500 to EUR 14,000 in cash and 0 weeks of your engineer’s time. In scenario three, the labor cost is EUR 0 now and EUR 15,000 to EUR 50,000 later, depending on which of the three things happens first.

The incident risk in scenario one is moderate. The pipeline works but has gaps. In scenario two, the risk is low. The pipeline is built by someone who has seen the failures. In scenario three, the risk is high and inevitable. A manual deploy process will eventually fail, and the failure will cost more than the pipeline.

The investor readiness in scenario one is good if the engineer who built it is still around. In scenario two, it is excellent. The pipeline is documented, the runbooks exist, the rollback has been tested. In scenario three, it is a liability that will surface in diligence.

What I tell founders

The founder in Tallinn ended up spending EUR 12,000 on a contractor who built the pipeline in three weeks. His CTO was skeptical about the cost until the contractor delivered a runbook for the first incident, which happened six weeks later at 2am on a Sunday. The on-call engineer followed the runbook, identified the failing service, rolled back with a git revert, and was back asleep in 14 minutes. The CTO told me later that the runbook alone justified the cost.

The EUR 3,500 freelancer quote was real too. You can find someone who will set up GitHub Actions, install ArgoCD, and configure a basic pipeline for EUR 3,500. What you will not get is the observability stack, the runbooks, the security baseline, the tested rollback, or the judgment that comes from having been paged at 4am on systems that broke in ways the documentation did not predict. You will get a pipeline that deploys. You will not get a pipeline that survives contact with production.

The EUR 40,000 CTO quote was also real. It was the cost of building the pipeline with a junior engineer who had never done it before, plus the cost of the gaps that would need to be closed later, plus a buffer for the inevitable delays. It was an honest estimate of what it costs to learn on the job. It was also the most expensive option, because it combined the time cost of scenario one with the cash cost of scenario two, and added the risk of scenario three on top.

The number that matters is not the build cost. It is the total cost of ownership over the first year: build cost plus cloud cost plus incident cost plus opportunity cost. By that measure, scenario two is almost always the cheapest. You pay a fixed amount for a working system, your engineers keep building the product, and the first incident is a 14-minute runbook exercise instead of a 6-hour fire drill.

If you are a startup reading this and trying to figure out which scenario you are in, Basecamp exists for exactly this reason: digitalaultis.com/basecamp

The pipeline is not the most expensive thing you will build. It is the cheapest thing that prevents the most expensive things from happening. Budget for it before the bill arrives.
