| Created | 2023 (Flowise launched 2023; YC S23) | 2023 (launched 2023 by Logspace; acquired DataStax Apr 2024) |
| Latest release | flowise@3.1.4 (2026-07-29) — final | v1.11.4 (2026-08-19) |
| License | Apache-2.0 | MIT |
| GitHub | FlowiseAI/Flowise — ~55.4k stars, archived 2026-08-13 (sunset plan had targeted 2026-08-10) | langflow-ai/langflow — ~156k stars, last commit 2026-08 |
| Pricing | discontinued — product sunset (EOL 2026-08-31); OSS code remains forkable under Apache-2.0 | OSS free (MIT); DataStax Langflow cloud was free tier + paid |
| Funding | total $500K (Seed, YC, 2023-01); acquired by Workday (announced 2025-08-14, terms undisclosed) | Acquired by DataStax Apr 2024; DataStax being acquired by IBM (announced Feb 2025) |
| Deployment | Both (OSS self-hosted; Flowise Cloud managed; air-gapped deployment supported) | OSS self-hosted (all major clouds); DataStax cloud deprecated; IBM acquisition path unclear |

| MCP | via official adapter — Flowise MCP node | native (first-party) — Langflow MCP server |
| OpenTelemetry | searched not found | via adapter — LangSmith / Arize |
| Optimised for | visual LangChain canvas + memory nodes | visual flow building + Mem0/Redis integrations |
| Anti-fit | not for production-grade SLA workloads | not for code-first only stacks |

Pros & cons
Flowise Memory
Pros: Visual builder lowers the bar for non-engineers to design memory pipelines; LangChain-compatible nodes.
Cons: Memory is as good as the LangChain primitive underneath — no novel architecture; less appealing to engineers building from code.
Langflow Memory
Pros: Strong DataStax / Astra DB integration gives it a managed-database memory backend out of the box.
Cons: Visual-builder positioning competes with Flowise without a clear differentiator on memory specifically.
