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 Merge?

Merge's Gateway adds text-to-video routing as the connector catalog expands into enterprise verticals

Merge is shipping weekly across three product lines: Gateway (AI model routing), Unified (data sync abstraction), and Agent Handler (connector tooling for AI agents). Gateway added text-to-video generation through fal.ai and Interfaze web search alongside seven new LLMs including Claude Fable 5.1 and Gemini 3.8 Flash. Agent Handler's connector catalog now includes Goldcast (73 tools), Luma (67 tools), and enterprise verticals like Clio, Avalara, and Nextech Practice+.

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.

Merge's Gateway adds text-to-video routing as the connector catalog expands into enterprise verticals

◆ Current state

Merge is shipping weekly across three product lines: Gateway (AI model routing), Unified (data sync abstraction), and Agent Handler (connector tooling for AI agents). Gateway added text-to-video generation through fal.ai and Interfaze web search alongside seven new LLMs including Claude Fable 5.1 and Gemini 3.8 Flash. Agent Handler's connector catalog now includes Goldcast (73 tools), Luma (67 tools), and enterprise verticals like Clio, Avalara, and Nextech Practice+.

◆ Where it's heading

Merge is moving beyond integration abstraction into full AI infrastructure. Gateway is no longer just an LLM router — it handles text, video generation, and web search through a single endpoint. Agent Handler's file-transfer-by-reference capability across SharePoint, Outlook, Gmail, and Drive removes a fundamental friction point where large files had to pass through conversation context. The connector expansion into events, legal, and healthcare suggests vertical market acceleration beyond the developer-first base.

◆ Prediction

Image generation routing to Gateway seems like the next logical multimodal addition. The connector catalog is growing fast enough that quality controls — rate-limit handling, edge-case robustness — will increasingly matter as much as new additions.
