Maintainer activity

22 people did triage or write work on this repository in the last 12 months.

Counts unlabeled, assigned, unassigned, milestoned, demilestoned, locked, unlocked over the last 12 months. These are issue and pull request events that require triage or write permission. Commits and code review are not counted. labeled and renamed are excluded because GitHub issue forms record the issue author as the actor. Figures from October 18, 2026. This count is not comparable across projects: each project's automation decides which of these events a person emits. How this is counted.

How this project is maintained

About 7% of issues opened in the past year have never received a reply. 94% of open issues come from outside the core team, so the backlog reflects real-world use rather than internal planning. Work labelled "documentation" is answered fastest, typically in about 6 hours, while "security" waits about 5 days. 54% of tracked open issues have had no activity in three months. 80% of issues opened in the past year have been closed, leaving a working backlog.

Detailed Description

Langflow is a platform for building and deploying AI-powered agents and workflows through visual composition and code.

The tool addresses the challenge of constructing complex AI applications by combining a visual builder interface with programmatic customization. Developers design workflows using a drag-and-drop canvas, then deploy them as REST APIs, MCP servers, or export them as JSON for integration into Python applications. The platform handles orchestration of multi-agent systems, conversation management, and retrieval workflows while supporting all major LLMs and vector databases out of the box.

Langflow suits teams building production AI applications who want to avoid managing infrastructure complexity. The visual builder makes it accessible to developers iterating quickly on agent logic, while source code access to every component ensures no architectural constraints for advanced use cases. An interactive playground with step-by-step execution control helps refine flows before deployment. The tool is particularly valuable for those needing enterprise-grade security, scalability, and observability integrations with LangSmith and LangFuse. A desktop distribution removes Python environment setup friction for new users on Windows and macOS.

The project maintains active development with regular feature additions across core capabilities. The codebase accepts contributions at all skill levels and provides clear development documentation for those building from source. Deployment flexibility spans local installation, Docker containerization, and cloud platform support, indicating ongoing investment in operational scenarios.
