Flowise
Flowise is an open-source, visual low-code platform for building LLM workflows and AI agents. It provides a drag-and-drop editor, a LangChain-compatible node library, and connectors for prompts, retrieval, tool calls, and multi-agent logic. One-sentence value: a vendor-neutral, extensible orchestration layer you can run under your control.
It is aimed at product builders, analysts, and small AI teams who need rapid prototyping and data control. Flowise reduces repetitive glue code for prompt orchestration, RAG, pick-your-LLM choices, and multi-step conversations. It also adds observability and human-in-the-loop checkpoints to help safer outputs. Self-hosting preserves data residency and compliance options.
Use Cases
- Answer personal notes from PDFs and CSVs
- Automate email drafts and summarize articles using RAG
- Build small hobby bots without writing orchestration code
- Internal knowledge assistant fed by internal documents and warehouse extracts
- Customer support assistant that pulls from docs and ticket databases
- Data discovery helper that runs SQL queries for analysts
Strengths
- Visual workflow builder for fast prototype-to-PoC cycles
- LangChain-compatible nodes leverage existing LLM patterns
- RAG connectors for PDFs, CSVs, SQL, and vector databases
- Multi-agent and chatflows decompose complex tasks into specialists
- Human-in-the-loop checkpoints improve safety and output quality
- Built-in observability with execution traces and metrics
- REST API and embedding widgets for app integration
- Open-source and extensible; you can add nodes and connectors
- Well-suited for self hosting; keeps data under your control
Limitations
- Self-hosting adds operational burden for scaling and security
- Hardware requirements rise when running large local models
- Needs engineering work for production readiness and rate limits
- Support is community-driven; enterprise SLAs require paid options
- Flowise Cloud residency guarantees are unverified (confirm before production)
Final Thoughts
Try Flowise now if you need rapid LLM prototyping and want control over data residency. Wait if you require turnkey, vendor-managed SLAs and zero operational responsibilities.
Choose Flowise Cloud when you prefer managed hosting, quotas, and lower operational burden. Managed plans add hosting and usage quotas, but verify current terms and residency guarantees before production.
