In their own words
Buildkite
Buildkite Pipelines is a CI/CD platform that dispatches pipeline steps as jobs to agents. Agents can be hosted by Buildkite or run in a customer's own infrastructure, including on-premises and cloud environments. Dynamic pipelines can generate and upload steps during a build, allowing a workflow to respond to code changes, test results or runtime logic. Test Engine collects results across testing frameworks and provides tools to track, analyze and act on them. It can detect and quarantine flaky tests, split tests across parallel jobs, and monitor test performance, reliability and ownership. Documented integrations include Slack, PagerDuty, Datadog, Honeycomb, OpenTelemetry, Amazon EventBridge, Artifactory, Docker Hub and Backstage. Buildkite lists TLS 1.2+ for data in transit and AES-256 encryption at rest, along with an annually audited SOC 2 Type II report. The Free Plan costs nothing and allows up to 5 users and 10 concurrent jobs. Pro costs $30 a month, billed per active user monthly, and includes up to 50 users and up to 250 concurrent agents, with 10 included.
Mergify
Mergify automates the path from pull request to a green main branch with merge queues, CI insights, flaky-test tools, and merge protections. Its queue rebases each pull request onto the latest main and merges only when CI passes against the combined state. Teams can combine pull requests into a single CI run; if that batch fails, Mergify can bisect it to locate the culprit. CI Insights reports unreliable jobs, retries them automatically, and provides data for investigating causes.
Merge Protections supports custom rules, scheduled merge windows, freeze periods, and exceptions for urgent fixes. The queue works with any CI that reports status checks to GitHub, while deeper CI Insights integrations are listed for selected providers. Integrations include GitHub, GitHub Enterprise, GitHub Actions, Jenkins, Buildkite, Slack, Datadog, and Terraform, among others. Mergify offers a free plan for open-source projects or private teams of up to five users. Max costs $21 per user per month and includes a 14-day free trial. Enterprise pricing is custom; it can include optional on-premise deployment and dedicated support. Mergify was founded in 2018 and is headquartered in Toulouse, France.
