Open Source Zoho Flow Alternatives

n8n is a workflow automation platform built for technical teams who find no-code tools too limiting but want something faster than building integrations from scratch. It sits in the middle: a visual canvas for building workflows, with the option to drop into JavaScript or Python at any step. That combination is what separates it from tools that force you to pick one or the other.

The platform connects to over 500 apps through pre-built nodes, with custom API support for anything not covered. Common use cases include onboarding automation, security incident enrichment, converting natural language into API calls, and generating customer insights from reviews. IT ops, SecOps, DevOps, and sales teams all show up in the documented use cases.

The AI agent capabilities are a significant part of what n8n has become. You can connect any AI model, including cloud or offline options, and build multi-agent setups and RAG systems. Every reasoning step is visible on the canvas, which matters when you need to audit what an agent actually did. Human-in-the-loop approvals can be inserted at any point, and structured inputs and outputs let you control exactly what data flows to and from AI steps.

Debugging is handled more practically than most tools. You can re-run a single step without replaying the entire workflow, mock external data to avoid waiting on third-party systems, and view logs without excessive clicking. AI workflows can be tested against real data before going to production.

Self-hosting is a first-class option. Full source code is available on GitHub, Docker deployment is supported, and the on-prem path includes SSO with SAML and LDAP, encrypted secret stores, RBAC permissions, audit logs, and Git-based version control. Teams that prefer not to manage infrastructure can use the hosted cloud version instead. If you're evaluating alternatives to n8n, options like ByteChef and Nango cover different parts of the integration and automation space.

Flowise is an open source platform for building AI agents and LLM-powered applications through a visual, drag-and-drop interface. It targets developers and teams who want to prototype and ship agentic systems without writing orchestration logic from scratch. The core idea is modular: you connect building blocks together visually, then deploy the result as a production-ready API or embedded chat widget.

There are two main flow types. Agentflow handles multi-agent systems where work is distributed across coordinated agents, each with defined roles and tools. Chatflow covers single-agent setups and chatbots, including tool calling and retrieval-augmented generation (RAG) from external data sources. Both support Human in the Loop (HITL), letting a human review or approve agent actions before they proceed.

Flowise connects to over 100 LLMs, embedding models, and vector databases. Finished flows are accessible via REST API, a TypeScript or Python SDK, or an embeddable chat widget. That makes it practical to drop AI functionality into an existing product without rebuilding infrastructure around it. If you've used something like Langflow or Dify, the general approach will feel familiar, though the feature sets differ.

Observability is built in. Full execution traces are available for every run, and the platform integrates with Prometheus and OpenTelemetry for teams that need production monitoring. Horizontal scaling is supported through message queues and workers, and deployment works in both cloud and on-premises environments.

The self-hosted version is fully open source. Flowise also offers a managed cloud with a free tier (2 flows, 100 predictions/month) and paid plans starting at $35/month for individuals who want unlimited flows. The Pro plan adds workspaces, role-based access control, and priority support for larger teams.

Flowise has recently joined Workday, though the open source project continues to be developed and maintained.
