Overview
Buildkite is a hybrid CI/CD platform founded in 2013 by Keith Pitt as a bootstrapped Australian startup. The company is now fully remote, with team members across more than 60 cities worldwide.
Its defining feature is a hybrid architecture: Buildkite hosts the control plane and dashboard as SaaS, while build agents run inside the customer's own infrastructure, keeping code and secrets under customer control.
Key Features
Buildkite includes Test Analytics and Test Engine for tracking and isolating flaky tests, package registry hosting following its 2023 PackageCloud acquisition, pipelines-as-code configuration, and Buildkite Hosted Agents, a managed compute option billed per vCPU-minute for teams that don't want to run their own agents.
Pricing
A free Developer tier covers small teams with limited concurrent agents. Pro starts around $15/user/month (annual) with unlimited agents and build minutes. Enterprise pricing is custom and adds SSO and audit logs. Hosted Agents compute is billed separately per vCPU-minute.
Key Features
Hybrid architecture — Managed control plane paired with self-hosted build agents inside customer infrastructure.
Buildkite Hosted Agents — Managed macOS and Linux compute billed per vCPU-minute for teams that don't want to self-host agents.
Test Analytics & Test Engine — Tracks test suite performance and identifies and isolates flaky tests.
Package registries — Store and distribute build artifacts and software packages, via the PackageCloud acquisition.
Pipelines as code — Define pipelines in YAML or dynamically upload them via API.
Unlimited build minutes — Pro and Enterprise plans include unlimited build minutes on self-hosted agents.
Third-party integrations — Connects with GitHub, GitLab, Bitbucket, and Slack.
