What is Buildkite?

Buildkite makes caching a built-in agent primitive and puts test workflows into Terraform.

Buildkite is a CI/CD platform that combines a hybrid agent model with a growing Test Engine. Its October releases include built-in caching (now GA), Terraform and REST management of Test Engine workflows, queue-filtered webhooks and cluster-level OpenTelemetry. The product is filling infrastructure gaps that teams previously solved with plugins or custom images.

What is Kestra?

Kestra's design system adds richer filters while 2.1.0 sits at its first release candidate.

Kestra's feed is quiet and internal: design-system v0.6.0 adds search, number filters and value counts to its KsFilter component, after v0.5.0 removed Bootstrap from the UI core. Kestra 2.1.0-rc1 was tagged on 10-20 with no release notes.

Buildkite makes caching a built-in agent primitive and puts test workflows into Terraform.

◆ Current state

Buildkite is a CI/CD platform that combines a hybrid agent model with a growing Test Engine. Its October releases include built-in caching (now GA), Terraform and REST management of Test Engine workflows, queue-filtered webhooks and cluster-level OpenTelemetry. The product is filling infrastructure gaps that teams previously solved with plugins or custom images.

◆ Where it's heading

The pattern is to centralize and codify: settings move from individual agents to clusters, and from the UI to Terraform and APIs, and capabilities such as caching move from plugins into the agent itself. Test Engine is turning into a programmable flaky-test management layer instead of a dashboard.

◆ Prediction

Expect more Test Engine monitors and actions that can be managed in code, and cache controls such as eviction and scoping, now that Cache is GA.

K
Kestra
INFRA · APIS
5.0

Kestra's design system adds richer filters while 2.1.0 sits at its first release candidate.

◆ Current state

Kestra's feed is quiet and internal: design-system v0.6.0 adds search, number filters and value counts to its KsFilter component, after v0.5.0 removed Bootstrap from the UI core. Kestra 2.1.0-rc1 was tagged on 10-20 with no release notes.

◆ Where it's heading

The visible work is a frontend refactor onto Kestra's own design system, which should show up as filter and table improvements in the 2.1 UI. The feed has no notes on 2.1's orchestration features.

◆ Prediction

Expect 2.1.0 to ship with new filtering in the UI; the entries don't say what else it contains.
