What is Flowise?
Flowise is an open-source platform for building agentic systems visually. Its Agentflow mode builds multi-agent systems with workflow orchestration, and Chatflow builds single-agent systems and chatbots with tool calling and retrieval (RAG) from data sources. It also offers human-in-the-loop review of agent tasks and execution traces with Prometheus and OpenTelemetry support. It installs with npm and exposes a prediction API for running flows.
The project is being wound down. The Flowise site announces a sunset: active feature development stopped on July 29, 2026, the GitHub repository was scheduled to move to public archive on August 10, 2026, and the core team's presence in Discord and GitHub ends on August 31, 2026. The GitHub page now shows the repository as archived and read-only since Aug 13, 2026. The Apache 2.0 licensed source stays on GitHub, and the team encourages users to fork it. Workday acquired Flowise in 2025. The sunset notice gives the reason as a shift toward coding agents, where rigid low-code workflows reach their limits on complex tasks.
