Total Monthly Cost by Team Size
Includes plan cost + overage minutes + estimated engineering time for self-hosted options.
5 devs, ~3K min/mo
20 devs, ~25K min/mo
50 devs, ~90K min/mo
Recommendation by Use Case
Zero friction, integrated, generous free tier. Team plan is cost-effective at this scale.
Native integration, single platform for full DevSecOps workflow. Self-hosted runners eliminate minute costs.
Cheapest per-minute Linux rate ($0.006), non-expiring credits, flexible resource classes.
GitHub Actions macOS is 10× Linux price. Mac mini agents pay back in weeks at moderate volume.
Infrastructure cost dominates. $200-400/mo infra beats $1,000-3,000+ SaaS at this volume.
BYOC model with Buildkite orchestration. Bring your GPU nodes without managing full CI infrastructure.
On-premise deployment required. CloudBees CI provides enterprise support for regulated environments.
Frequently Asked Questions
Which CI/CD platform is best for small teams?
For small teams (1-10 developers) with GitHub repositories, GitHub Actions is the clear winner: integrated, free tier is generous (2,000 Linux min/mo), and no additional tooling needed. For GitLab users, GitLab CI is the natural choice. CircleCI is a strong option for teams wanting flexible resource classes and non-expiring credits on paid plans. Jenkins is generally too much overhead for small teams.
What is the cheapest CI/CD for high build volumes?
At high build volumes (50,000+ minutes/month), self-hosted infrastructure consistently wins on pure spend. Jenkins or GitLab CE on cloud VMs costs $150-400/month regardless of minute count. GitHub Actions at 50,000 minutes costs ~$500/month in Linux runner charges. Self-hosted Buildkite agents give you predictable costs with Buildkite's orchestration layer. The catch: self-hosted requires engineering time to maintain.
GitHub Actions vs GitLab CI — which should I choose?
Choose GitHub Actions if your code is on GitHub and you want zero-friction CI integrated with pull requests, Actions marketplace, and GitHub's ecosystem. Choose GitLab CI if your code is on GitLab, you want built-in DevSecOps (SAST, DAST, dependency scanning), or you need a single platform for issue tracking, code review, and CI/CD. GitLab CI's YAML syntax is more verbose but more powerful for complex pipelines.
Is CircleCI still worth using in 2026?
CircleCI remains competitive in 2026, particularly for teams not tied to GitHub or GitLab ecosystems. Its credit system allows precise resource class selection (avoiding over-provisioning), macOS runners are cheaper than GitHub Actions ($0.03/min vs $0.082/min), and non-expiring credits on paid plans suit variable build loads. CircleCI orbs (reusable config packages) are more mature than GitHub Actions reusable workflows for complex CI patterns.
What is Buildkite and who is it for?
Buildkite is a hybrid CI/CD platform: Buildkite manages the orchestration, queuing, and UI while you supply the compute (agents on your own infrastructure). Pricing is $9-15/user/month plus your infrastructure costs. Buildkite is popular with teams that need custom build environments (specific hardware, software, or security requirements), want no per-minute charges, and have the engineering capacity to manage build agents. Etsy, Shopify, and Atlassian use Buildkite.
