VERDICT

Should I use Flowise?

Open source generative AI development platform for building AI agents, LLM orchestration, and more - flowiseai.com

Depends. Buy if you're a developer prototyping AI agents on a self-hosted, sandboxed instance — it's free and fast to iterate. Avoid for internet-exposed or sensitive production use: multiple actively-exploited critical RCEs have been disclosed.

Confidence

Medium. Based on 20+ public sources, including 8 security advisories and researcher writeups. Some review snippets were truncated, limiting quotable user feedback.
