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 Userback?

Userback's Sites turn out to be a multi-site workspace, and the first follow-up targets agencies.

Userback has spent 2026 widening where feedback comes from (mobile SDK, Slack, mobile surveys) and adding an AI layer on top (Insights themes, video transcription, AI Context Search). The October 28 follow-up finally shows what Sites is: a per-site container with its own Site Key, settings, widget and feedback list. The new tools are prefixed readable feedback IDs that pass through to Jira, copying widget settings between Sites, open-feedback counts on the Sites page, and survey targeting by query string and hash.

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.

5.0

Userback's Sites turn out to be a multi-site workspace, and the first follow-up targets agencies.

◆ Current state

Userback has spent 2026 widening where feedback comes from (mobile SDK, Slack, mobile surveys) and adding an AI layer on top (Insights themes, video transcription, AI Context Search). The October 28 follow-up finally shows what Sites is: a per-site container with its own Site Key, settings, widget and feedback list. The new tools are prefixed readable feedback IDs that pass through to Jira, copying widget settings between Sites, open-feedback counts on the Sites page, and survey targeting by query string and hash.

◆ Where it's heading

Sites moves Userback toward running many properties from one account. Copying widget settings and sorting Sites by open feedback are built for agencies with a Site per client. The readable IDs that travel into Jira and other integrations show the same push seen in the 'Sent to Integrations' filter: making Userback the traceable start of a ticket, not a separate inbox.

◆ Prediction

Expect more cross-Site tooling, such as copying integrations or templates between Sites, since the October 28 notes say integrations still have to be set up per Site.
