It supports multi-environment execution (Docker, Linux, macOS, Windows, Arm, GPU), provides an Orbs ecosystem for reusable pipeline config, and offers both managed cloud and self-hosted deployment options. New AI capabilities include the Chunk agent for pipeline automation and flaky-test repair, and an MCP server for natural-language interaction with build context.

Buildkite

Rank #3 · 13.3% visibility

Buildkite is a scale-out CI/CD and software delivery platform comprising four integrated products: Pipelines for flexible CI/CD workflow automation with self-hosted or cloud-hosted agents and unlimited concurrency; Test Engine for test suite analytics, flaky test detection, auto-quarantine, and intelligent test splitting; Package Registries for secure private artifact management and software supply chain security (SLSA provenance, threat scanning, license checks); and Mobile Delivery Cloud for optimized iOS and Android app CI/CD. A fifth capability—Agentic Workflows—provides MCP server integration, LLM provider connectivity, and composable AI-powered pipeline building blocks. The platform's defining characteristic is its hybrid architecture, enabling unlimited build parallelism, enterprise security compliance, and cloud-agnostic infrastructure flexibility.

GitLab is available as a cloud-hosted SaaS service (GitLab.com), as self-managed Community or Enterprise Editions deployable on-premises or in any cloud, and as a single-tenant Dedicated offering managed by GitLab.

Harness

Rank #5 · 10.0% visibility

Harness is an AI-native software delivery platform delivering CI, CD & GitOps, feature flags, cloud cost management, security testing orchestration, infrastructure as code management, chaos/resilience testing, an internal developer portal, and software engineering insights in a single modular SaaS offering, designed to automate the entire path from code commit to production.

TeamCity

Rank #6 · 6.0% visibility

TeamCity by JetBrains is a mature, enterprise-grade CI/CD server that automates build, test, and deployment pipelines across on-premises, cloud, and hybrid environments. It combines Kotlin DSL pipeline-as-code with a modern visual pipeline editor, broad VCS and cloud integrations, and built-in test intelligence to help teams—from small shops on the free tier to large enterprises managing thousands of daily builds—deliver software faster and more reliably.

Semaphore

Rank #7 · 3.3% visibility

Semaphore is an AI-driven CI/CD platform offering fast, reliable pipeline execution across cloud, hybrid, and self-hosted environments. It provides a visual pipeline editor, parallel job execution, flaky test detection, deployment automations with approval gates, and deep observability—all under a pay-per-second compute model. Its 2025 open-source release makes the core platform available for self-hosting without cost.

CloudBees

Rank #10 · 2.0% visibility

CloudBees Unify is an enterprise software delivery control and context plane that connects, governs, and accelerates CI/CD across multi-tool, hybrid-cloud environments. Built on a foundation of enterprise Jenkins management and CD/RO release orchestration, it extends to feature management, continuous security and compliance automation, AI-driven test intelligence, and cross-SDLC analytics—enabling large regulated enterprises to deliver software faster, at scale, with full auditability and governance.

Nx

Rank #9 · 2.0% visibility

Nx is a smart monorepo build system and CI platform. The open-source core provides intelligent task caching, project graph analysis, affected-command execution, code generators, and module boundary enforcement for JavaScript, TypeScript, and polyglot codebases. Nx Cloud is the commercial SaaS layer adding remote caching (Nx Replay), distributed task execution (Nx Agents), AI-powered self-healing CI, and flaky test detection. Nx Enterprise extends Nx Cloud with on-premises deployment, SAML SSO, conformance rules, cross-repository workspace graphs (Polygraph), and white-glove support.

Turborepo

Rank #8 · 2.0% visibility

Turborepo is a Rust-based, open-source build system and task orchestrator for JavaScript and TypeScript monorepos. It speeds up local development and CI by caching task outputs (builds, tests, lint) and replaying them on cache hits, running tasks in parallel across CPU cores, and sharing a remote cache across all team members and CI agents via Vercel Remote Cache or a self-hosted alternative.

Dagger

Rank #11 · 1.3% visibility

Dagger is a container-native CI/CD automation engine and SDK platform that lets engineering teams write, run, and share pipeline logic as real code rather than YAML or shell scripts. It is open source, runs locally and in any CI environment, and is complemented by Dagger Cloud for pipeline observability and the Daggerverse community module registry.

Jenkins

Rank #12 · 1.3% visibility

Jenkins is an extensible, self-hosted, open-source automation server used to automate building, testing, and deploying software. Its defining strength is a plugin architecture with 2,000+ community-maintained plugins integrating with virtually every tool in the CI/CD toolchain. Pipelines are defined as code using Groovy-based Jenkinsfiles and can be distributed across multiple build agents for parallel and cross-platform execution. Jenkins is platform-agnostic, community-governed under the Continuous Delivery Foundation, and free to use under the MIT License.

Depot

Rank #14 · 0.7% visibility

Depot is a managed build acceleration platform providing remote Docker container builds, high-performance GitHub Actions runners, a new CI engine (Depot CI), distributed remote caching, a container registry, and agent compute sandboxes.

Earthly

Rank #13 · 0.7% visibility

Earthly Technologies is a San Francisco-based developer tools company operating two products at different lifecycle stages. Its legacy product, Earthfiles, is an open-source CI/CD build framework (MPL-2.0) that uses container isolation and BuildKit-based layer caching to deliver reproducible, parallelized builds with a Dockerfile/Makefile-inspired syntax; active commercial and maintenance support ended in 2025, and it is now community-maintained. The current commercial product, Earthly Lunar, is an engineering governance platform that instruments existing CI/CD pipelines and source repositories to collect structured SDLC metadata, then evaluates that metadata against customizable guardrails-as-code policies—enforcing engineering standards deterministically at AI agent hooks, pull request checks, and deployment gates across an entire organization without requiring per-repo pipeline modifications.
