Flowise review

Flowise is an open-source visual platform for building AI agents, chat assistants, and workflows. You connect components to create applications that can call tools, retrieve information from a knowledge base, or coordinate multiple agents. The feature description also lists human review loops, execution traces, APIs, embedded chat, and TypeScript and Python SDKs.

Deployment can be on Flowise Cloud or on your own infrastructure. The feature description says self-hosted setups can scale horizontally using message queues and workers, so teams can manage infrastructure themselves rather than rely on a hosted plan.

The catch is significant: Flowise’s homepage says the product is being sunset. It remains a capable visual agent builder, but that announcement makes it a risky foundation for a new production project. Teams considering it should weigh its current capabilities against the uncertainty around its future before moving workflows onto it.

Flowise brings common LLM application building blocks into a visual workflow. That can make it easier to map how an assistant retrieves knowledge, calls tools, or hands work between agents than stitching every step together in code. Its feature description covers both single-agent chat assistants and distributed multi-agent workflows, as well as human review and execution traces.

The deployment choices also suit different levels of operational ownership: use the hosted service for a smaller setup, or self-host if you want to manage infrastructure and usage yourself. The published pricing information lists the open-source self-hosted option at $0, with unlimited seats and usage subject to your infrastructure.

• The Free hosted plan lists 2 flows and assistants, 100 predictions per month, and 5MB of storage.
• The Starter plan lists unlimited flows and assistants, 10,000 predictions per month, and 1GB of storage for $35 per month.
• For teams that need to extend the product, the feature description lists APIs, embedded chat, and TypeScript and Python SDKs.

Reddit discussions also describe Flowise as LLM-focused, unlike general automation tools that users may pair with it for other triggers and integrations.

The announced sunset is the main drawback, not a missing workflow feature. A product being sunset is a poor bet for a new system that needs ongoing maintenance, even if the current builder meets your requirements. The homepage does not provide a sunset date or migration plan in the published material, so we can’t say how long the product will remain available.

Hosted capacity is limited on the lower plans. The Free plan caps usage at 100 predictions a month, 2 flows and assistants, and 5MB of storage. Starter costs $35 monthly and raises the limits to 10,000 predictions and 1GB. Pro is $65 monthly for 50,000 predictions, 10GB of storage, 5 included users, and unlimited workspaces; additional Pro users are listed at $15 per user monthly. Enterprise pricing is custom, and annual prices are not published. The listed Starter offer includes a first month free; the Free plan is separate.

Self-hosting avoids a subscription price, but unlimited usage still depends on your own infrastructure. A beginner in one Reddit thread says the docs lack detail, and another commenter recommends LangChain’s documentation for additional help. That means the visual editor may not remove the need to understand the underlying components.

Flowise lists a free hosted plan, Starter at $35/month and Pro at $65/month, based on pricing details checked November 6, 2026. Free is capped at 2 flows and assistants, 100 predictions a month and 5MB of storage. Starter removes the flow and assistant cap and raises limits to 10,000 predictions and 1GB of storage. Its first month is free. Pro costs $30 more per month and includes 5 users, 50,000 predictions, 10GB of storage and unlimited workspaces. Additional Pro users cost $15 per user monthly.

The jump from Starter to Pro buys more usage and workspace capacity, but not unlimited predictions. Enterprise pricing is custom and not published. Annual prices are also not published, so there’s no listed annual discount to compare. Self-hosting is listed at $0 under Apache 2.0, with unlimited usage subject to your own infrastructure; that doesn’t make hosting or maintenance cost-free. Check which offer applies before budgeting: the pricing details list a one-month free trial, while Starter specifically advertises its first month free.

Flowise’s homepage says the product is being sunset, so we’d be cautious about starting a new project that needs a long runway. Existing teams should first inventory their flows, assistants, knowledge sources, credentials, and integrations—including any APIs, embedded chat, or TypeScript and Python SDK use—before planning a move. The work depends on how much of the application relies on those pieces; the published materials don’t give a migration guide or estimate.

Flowise is open source under Apache 2.0, and its feature list includes APIs and SDKs, but neither fact guarantees a straightforward export to another platform. The available materials don’t specify data-export formats, portability limits, or a supported migration path. Confirm what can be exported and test rebuilding a representative workflow before switching. Self-hosting may avoid hosted-plan prediction caps, but it still ties operations to infrastructure your team manages.

We don’t have Reddit posts or comments in the published material, so we can’t substantiate what users say makes them leave. The announced sunset is the clearest stated reason to assess alternatives.
