Langflow vs Activepieces
Langflow scores 90 to Activepieces's 80 on public evidence for AI workflow automation, and they rank #3 and #4 there. Both are free to start. Numbers below are the same public signals the ranking uses, recomputed nightly — nothing here is sponsored.
Langflow
Visual low-code builder for RAG and multi-agent flows, acquired by DataStax and now part of IBM.
+ Python-native components can be edited inline, so flows are not limited to built-in nodes.
− Several critical security vulnerabilities in 2025 made exposed instances risky.
Activepieces
Open-source Zapier alternative with AI pieces and an MCP server for agent tool access.
+ MIT-licensed core with pieces written in TypeScript that are easy to extend.
− Far fewer integrations than Zapier or n8n.
