Webhooks in Buildkite have received significant enhancements with the 2.0 agent release, including new events for improved visibility of agents and the build queue, project and branch-specific event filtering, and support for SNI endpoints like AWS Lambda. The updated webhooks allow teams to customize and extend Buildkite, with documentation available to guide integration and examples offered for implementing features like a LIFX-powered build light. Notable uses of these webhooks include Shopify's Agent Clustering Dashboard, which leverages AWS and Docker for efficient agent management and rapid deployment, and Ferocia's CI Light Board, a creative installation using LIFX bulbs and Elixir to visualize build statuses. Buildkite provides a robust platform for CI/CD and automation tasks, offering integration with tools like GitHub and Slack, which has attracted teams such as Shopify and Ferocia to streamline their development processes.
