What is Dify?

Pivoting from RAG app-builder to an agent platform, now stabilizing the surface

Dify has spent the last two quarters expanding its capability surface from a workflow/RAG app builder into agent territory: a Human-in-the-Loop node, then a sandboxed Agent runtime with a Skill Editor and collaboration beta. The two most recent releases (1.14.1, 1.14.2) shift register entirely to security hardening, workflow reliability, and self-hosted deployment cleanup, suggesting the new surface is being consolidated rather than extended.

What is Semantic Kernel?

Semantic Kernel hands off to Microsoft Agent Framework while locking down its plugin surface.

Semantic Kernel is in a transitional phase: Microsoft is positioning the new Microsoft Agent Framework as its successor, shipping AF 1.0-compatible migration samples and adding successor callouts to the READMEs. In parallel, the bulk of release content is a sustained security-hardening campaign across the plugin and connector surface - default-on URL validation for OpenAPI plugins, deny-by-default file access for Document and CloudDrive plugins, SQL-injection escaping in SQL/Redis connectors, and a run of CVE/GHSA dependency remediations.

Pivoting from RAG app-builder to an agent platform, now stabilizing the surface

◆ Current state

Dify has spent the last two quarters expanding its capability surface from a workflow/RAG app builder into agent territory: a Human-in-the-Loop node, then a sandboxed Agent runtime with a Skill Editor and collaboration beta. The two most recent releases (1.14.1, 1.14.2) shift register entirely to security hardening, workflow reliability, and self-hosted deployment cleanup, suggesting the new surface is being consolidated rather than extended.

◆ Where it's heading

The arc is clear: native human oversight (1.13.0) and agentic execution (1.14.0-rc1) were the directional bets, and the patch releases since are paying down the operational and security debt those features created — tenant isolation fixes, CVE upgrades, Celery/PubSub deployment guidance, and a continued migration to the @langgenius/dify-ui design system. An 'init agent server' commit in 1.14.2 signals the agent runtime is still being built out under the hood.

◆ Prediction

Expect a stable 1.14.0 GA that promotes the Agent + Skills experience out of preview, followed by continued agent-server buildout. Near-term patch releases will keep emphasizing security and self-hosted deployment ergonomics.

Semantic Kernel hands off to Microsoft Agent Framework while locking down its plugin surface.

◆ Current state

Semantic Kernel is in a transitional phase: Microsoft is positioning the new Microsoft Agent Framework as its successor, shipping AF 1.0-compatible migration samples and adding successor callouts to the READMEs. In parallel, the bulk of release content is a sustained security-hardening campaign across the plugin and connector surface - default-on URL validation for OpenAPI plugins, deny-by-default file access for Document and CloudDrive plugins, SQL-injection escaping in SQL/Redis connectors, and a run of CVE/GHSA dependency remediations.

◆ Where it's heading

SK appears to be entering maintenance-and-migration mode: net-new capability is thin, mostly vector-store and connector refinements, while effort concentrates on hardening and on easing the path to Agent Framework. The breaking security-default changes in the WebFileDownload and Document plugins signal a deliberate lockdown of the plugin surface ahead of handoff.

◆ Prediction

Expect the Agent Framework migration messaging to intensify and net-new SK feature work to keep tapering, with releases dominated by security and dependency maintenance and connector fixes rather than new capabilities.
