What is Flowise
Flowise is an open-source visual development platform for chat assistants, LLM workflows and single- or multi-agent systems, with APIs, SDKs, embedded chat, tracing and evaluation.
Availability warning (September 2026): Flowise announced a code freeze on July 29, archived its official repository on August 10 and reached end of life on August 31, 2026. The Apache-licensed source remains available for self-hosting or forks, but the core team has ended official development and support. Confirm any remaining Cloud billing and service availability directly before buying; the old Cloud plan figures below are historical, not a current purchase recommendation.
Cloud plans
The remaining product page still displays Free at US$0 per month (two flows and assistants, 100 monthly predictions and 5MB storage), Starter at US$35 per month (unlimited flows and assistants, 10,000 predictions and 1GB), and Pro at US$65 per month (50,000 predictions, 10GB, five users and priority support). Because the vendor has announced end of life, these visible figures should not be treated as confirmation that new Cloud subscriptions or support remain available.
Self-hosting
The open-source product can still be deployed on infrastructure operated by the user, with separate infrastructure, model and maintenance costs. The vendor explicitly encourages teams that need continued updates to fork the repository; no ongoing core-team maintenance should be assumed.
