I need a CI/CD tool that uses YAML configuration and does not require a dedicated Jenkins server.

Yes. The main options that fit are:

• GitHub Actions — CI/CD is defined in YAML under .github/workflows/, and GitHub provides hosted runners, so you don't need to operate a Jenkins server or build machine yourself.
• GitLab CI/CD — uses .gitlab-ci.yml and GitLab.com provides managed runners that require no runner infrastructure on your side.
• CircleCI — uses a repository-based .circleci/config.yml and runs pipelines through CircleCI's cloud service.

If you want the simplest Jenkins replacement

GitHub Actions is a natural choice if your code is already on GitHub. A minimal pipeline looks like:

name: CI

on:
  push:
    branches: [main]
  pull_request:

jobs:
  test:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v4

      - name: Install dependencies
        run: npm ci

      - name: Run tests
        run: npm test

There is no Jenkins controller/server to install or maintain; GitHub supplies the hosted execution environment.

If you tell me where your repository lives (GitHub, GitLab, Bitbucket, Azure DevOps, etc.) and what you're deploying (Docker, Kubernetes, AWS, Azure, on-prem, etc.), I can narrow it down to the most suitable 2–3 options.

Here are the best CI/CD tools that use YAML configuration files and run entirely without a heavy, dedicated server like Jenkins:

• GitHub Actions : Uses native .github/workflows/*.yml files stored right in your repository. It is hosted and managed entirely by GitHub, meaning zero server maintenance for you.
• GitLab CI/CD : Uses a .gitlab-ci.yml file. While GitLab can be self-hosted, their cloud offering (GitLab.com ) handles all the orchestration infrastructure out of the box, or you can just spin up lightweight local runners.
• CircleCI : A fully managed cloud CI/CD platform driven by a .circleci/config.yml file. It has a serverless architecture, so you never have to provision or maintain a persistent build machine.
• Bitbucket Pipelines : Built directly into Bitbucket Cloud, it uses a bitbucket-pipelines.yml file in your repository root, removing any need for standalone server upkeep.
• Woodpecker CI : If you want something self-hosted but lightweight (unlike Jenkins), Woodpecker is a simple, fast CI engine built on Docker that uses YAML pipelines and minimal resources.

To help narrow down the best choice, let me know:

• Where is your code hosted (GitHub, GitLab, Bitbucket, or self-hosted)?
• Do you want a fully managed cloud service or something self-hosted on a tiny VM?

Yes. GitHub Actions is probably the best fit if your goal is “Jenkins-style CI/CD, but without maintaining a Jenkins server.”

• YAML configuration: workflows live in your repository under .github/workflows/*.yml.
• No dedicated CI server: GitHub provides hosted runners that automatically provision VMs for jobs and tear them down afterward.
• CI + CD: supports builds, tests, deployments, approvals, secrets, artifacts, matrix builds, etc.
• Self-hosting is optional: you can use GitHub-hosted runners unless you specifically need your own infrastructure.

For example:

name: CI

on:
  push:
    branches: [main]
  pull_request:

jobs:
  test:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v6

      - name: Install dependencies
        run: npm ci

      - name: Run tests
        run: npm test

      - name: Build
        run: npm run build

Other good options

• GitLab CI/CD — excellent alternative if your repositories are on GitLab. Pipelines are defined in .gitlab-ci.yml, and GitLab.com provides fully managed hosted runners, so you don't need to operate a Jenkins-like server.
• Bitbucket Pipelines — worth considering if you're already heavily invested in Bitbucket/Jira.

My recommendation: If your code is on GitHub → GitHub Actions. If it's on GitLab → GitLab CI/CD. Both give you YAML-based pipelines with managed execution, eliminating the dedicated Jenkins server.

Here are the top CI/CD tools that use YAML configuration and run fully hosted or cloud-managed without requiring you to maintain a dedicated Jenkins server:

• GitHub Actions : Baked directly into GitHub, utilizing .github/workflows/*.yml files. It requires zero infrastructure setup, offers a massive marketplace of pre-built actions, and runs on GitHub-hosted runners out of the box.
• GitLab CI/CD : Managed directly inside GitLab using a single .gitlab-ci.yml file in your repository. GitLab provides free shared runner minutes on the cloud so you don’t have to host a control plane or server yourself.
• CircleCI : A powerful cloud-managed platform driven by a .circleci/config.yml file. It features a serverless architecture, fast parallel job processing, and deep integrations with major cloud providers and version control systems.
• Bitbucket Pipelines : Built natively into Bitbucket, configured entirely via a bitbucket-pipelines.yml file at the root of your repository, eliminating any separate CI maintenance overhead.
• Buildkite : Uses a hybrid approach where the web UI and scheduling (the control plane) are fully hosted by Buildkite, while you run lightweight agent scripts on your own infrastructure or cloud. Configuration is managed via a pipeline YAML file (pipeline.yml).

To help narrow down the best fit, tell me:

• Where is your source code hosted? (GitHub, GitLab, Bitbucket, etc.)
• Do you need free/cloud-hosted runners , or do you prefer running agents on your own hardware?

A strong fit is GitHub Actions.

• YAML-based: workflows are defined in .github/workflows/*.yml files.
• No Jenkins server: GitHub provides the CI/CD service and hosted runners for you.
• Hosted execution: each job can run on a GitHub-hosted VM, which GitHub provisions and decommissions automatically.
• Cross-platform: hosted runners are available for Linux, Windows, and macOS.
• Good ecosystem: built-in integrations/actions for Docker, cloud deployments, testing, security scanning, and more.

Example:

name: CI

on:
  push:
    branches: [main]
  pull_request:

jobs:
  test:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v6

      - name: Install dependencies
        run: npm ci

      - name: Run tests
        run: npm test

      - name: Build
        run: npm run build

Alternative: If your repositories are on GitLab, GitLab CI/CD is similarly well suited. GitLab.com provides hosted runners that are integrated into the service, so you don't need to manage your own CI server.

My recommendation:

• GitHub repository → GitHub Actions
• GitLab repository → GitLab CI/CD
• Need to keep everything self-hosted/on-prem → consider GitLab Runner, Buildkite, or similar rather than Jenkins.

Here are the top modern CI/CD tools that use YAML configuration and run serverless or in the cloud (no dedicated Jenkins server required):

• GitHub Actions - Deeply integrated into GitHub , it uses .github/workflows/*.yml files. It offers a massive marketplace of community actions and free minutes for public/private repositories, running entirely on GitHub's hosted runners.
• GitLab CI/CD - Built directly into GitLab , configuration is handled via a single .gitlab-yml file in your repository. It provides seamless integration from code commit to deployment with powerful built-in security scanning.
• CircleCI - A cloud-native platform using .circleci/config.yml . It is known for high-speed builds, robust parallelization, and easy integration with GitHub and Bitbucket without managing your own infrastructure.
• Bitbucket Pipelines - Native CI/CD for Bitbucket repositories, configured via bitbucket-pipelines.yml . It spins up automatically on your cloud-hosted workspace without needing an external build server.
• Travis CI - One of the original YAML-driven cloud CI platforms configured via .travis.yml . It integrates smoothly with GitHub for testing and deploying open-source and private projects.

Yes. If you want YAML-based CI/CD without maintaining a dedicated Jenkins server, the strongest options are:

• github.com — Excellent if your code is on GitHub. Workflows are defined in YAML under .github/workflows/, and GitHub provides the hosted runners, so there’s no Jenkins server to maintain.
• about.gitlab.com — Define pipelines in .gitlab-ci.yml. With GitLab.com, you can use GitLab-provided runners rather than running your own CI server.
• circleci.com — Cloud-hosted CI/CD with pipelines defined in .circleci/config.yml. It supports GitHub, GitLab, and Bitbucket, and its cloud service eliminates the need for a Jenkins-style server.

My recommendation

If you're already using GitHub, I'd choose GitHub Actions. It's the closest fit to "Jenkins, but no Jenkins server."

If you're looking for a VCS-independent hosted CI/CD service, I'd lean toward CircleCI.

If you're using GitLab, use GitLab CI/CD—it's deeply integrated and the YAML configuration is straightforward.

If you tell me whether you're using GitHub, GitLab, Bitbucket, or something else, I can recommend the best one and show you a sample YAML pipeline.

Here are the best modern CI/CD tools that use YAML configuration files and run via cloud-native SaaS or decoupled architectures, freeing you from managing a dedicated, always-on Jenkins controller:

• GitHub Actions : Built directly into GitHub, it requires zero server maintenance. You simply drop a .yml file into your .github/workflows/ directory, and GitHub handles the runner infrastructure (or you can spin up your own ephemeral self-hosted runners if needed).
• GitLab CI/CD : Fully integrated into GitLab, pipelines are defined using a .gitlab-ci.yml file at the root of your repository. GitLab manages the orchestration layer, and you can use their shared runners or attach lightweight worker agents.
• Bitbucket Pipelines : Native to Bitbucket, this cloud-managed option uses a bitbucket-pipelines.yml file in your repository. It requires no dedicated infrastructure setup and ties straight into your deployments and pull requests.
• CircleCI : A powerful standalone cloud CI/CD platform that connects to your GitHub or Bitbucket accounts. It uses a .circleci/config.yml file to orchestrate blazing-fast, containerized workflows without you ever touching a physical or virtual CI server box.
• Buildkite : A hybrid approach where the central orchestration, UI, and pipeline management (configured via YAML/pipelines in your repo) are hosted by Buildkite, but the actual build jobs execute on lightweight agents running securely inside your own infrastructure.

To help narrow down the best fit, let me know:

• Where is your code hosted (GitHub, GitLab, Bitbucket, or self-hosted)?
• Do you prefer a fully hosted cloud SaaS , or do you need a self-hosted option that still avoids Jenkins-style overhead?

Modern cloud-based and Git-integrated CI/CD solutions entirely eliminate the need to provision, patch, or maintain a dedicated server like Jenkins. They use clean YAML configuration files stored right in your repository.

Here are the top options categorized by where your code lives:

• GitHub Actions — Baked directly into GitHub , using .github/workflows/*.yml files. It features a massive community marketplace of pre-built actions, native matrix builds, and zero infrastructure to manage.
• GitLab CI/CD — Built into GitLab and configured via a single .gitlab-ci.yml file in your root directory. It offers fantastic integrated security scanning, robust container registries, and managed runners out of the box.
• CircleCI — A dedicated platform that hooks into GitHub or Bitbucket via .circleci/config.yml . It's known for fast build speeds, powerful caching, and advanced parallelization controls.
• Bitbucket Pipelines — Built natively into Bitbucket , configured using a bitbucket-pipelines.yml file. It's the most seamless choice if your repositories already reside within the Atlassian ecosystem.
• Buildkite — A hybrid approach where the orchestration UI is hosted for you, but you run lightweight, secure agents on your own infrastructure (or local machine) while keeping your pipelines defined in YAML.

To help narrow down the best fit, tell me:

• Where is your code repository currently hosted (GitHub, GitLab, Bitbucket, etc.)?
• Do you need free public/private tier minutes from a managed cloud, or do you prefer to run agents on your own hardware?

If you want YAML-based CI/CD without maintaining a dedicated Jenkins server, my first choice would be GitHub Actions.

• GitHub Actions — Define workflows in YAML under .github/workflows/. GitHub provides hosted runners, so you don't need to operate a Jenkins controller/server. Jobs run on GitHub-provisioned VMs or containers.
• GitLab CI/CD — Uses a .gitlab-ci.yml file and GitLab-hosted infrastructure/runners. It is a strong choice if your repositories are already on GitLab.
• Bitbucket Pipelines — Another hosted, YAML-configured option if you're using Bitbucket.

Recommendation

Use GitHub Actions if your code is on GitHub. A basic pipeline looks like:

name: CI

on:
  push:
    branches: [main]
  pull_request:

jobs:
  build-and-test:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v6

      - name: Install dependencies
        run: npm ci

      - name: Test
        run: npm test

      - name: Build
        run: npm run build

There is no Jenkins controller to install, patch, back up, or keep running. GitHub provisions the runner when the job starts and decommissions it afterward.

If you tell me where your code is hosted (GitHub, GitLab, Bitbucket, Azure DevOps, etc.) and what you're deploying (Docker, Kubernetes, AWS, Azure, a VM, etc.), I can recommend the best fit.
