Buildkite has been running continuous integration pipelines for major tech companies since 2013, handling code builds for OpenAI, Airbnb, Canva, Uber and Shopify throughout their rapid growth phases. Their platform focuses on turning large-scale operations into faster, reliable release cycles by spreading work across multiple agents instead of relying on a single, faster runner. Today they orchestrate CI workloads for a new wave of AI and infrastructure players—Cursor, Anthropic, Mistral, xAI—alongside Meta, Discord, Reddit, Ramp, Boston Dynamics, Applied Intuition, ASML, Planetscale, Pierre and Bun. They also support the toolchains behind vLLM, Bazel and Backstage. Buildkite claims to power software used by over a billion people every day and offers a 30-day trial to test its full suite of orchestration features.
