Open-source framework for building agentic and RAG applications visually

Langflow's 1.11 agent-protocol work reaches the desktop app.

◆Current state
Langflow 1.11 is now available as a Desktop build, following the OSS release that carried the substance: Human-in-the-Loop checkpoints, A2A protocol support, AG-UI streaming for the Workflow API, and first-class multi-vector retrieval with ColBERT-style late interaction and ColPali-style visual document retrieval. The desktop entry is packaging, not new capability.
◆Where it's heading
Langflow keeps attaching agent-interoperability protocols and serious retrieval to what began as a visual flow builder. The pattern is consistent: each minor version adds a standard other agent systems can speak to, then follows with a desktop build a fortnight later. The engineering posts about an ~89% memory reduction suggest the platform work is aimed at production deployment, not demos.
◆Prediction
Expect 1.12 to continue the protocol trajectory rather than the visual editor, with the desktop build trailing the OSS release by a couple of weeks as it did for 1.10 and 1.11.
