Flowise pricing
Agent orchestration

Visual tool-calling agents, named sub-agents, and composable sub-workflows.

Can agents delegate to specialist agents and workflow tools with clear execution boundaries?
RAG and retrieval

Built-in document ingestion, vector retrieval, metadata filters, and reranking.

What is native, what depends on an external vector store, and how are data access controls enforced?
MCP connectivity

Use MCP tool servers from agents or expose Heym workflows as an MCP server.

Does the product support the required MCP client, server, authentication, and audit patterns?
Human review and guardrails

Approval checkpoints with shareable review links, configurable guardrails, and editable reviewer input.

Can a workflow pause for an accountable reviewer and record its approval, edit, or refusal?
Evaluation suites

Test cases, model comparisons, pass/fail tracking, and LLM-as-judge scoring for AI workflows.

Can teams regression-test an AI workflow before changing a model, prompt, tool, or knowledge base?
LLM traces and telemetry

Full invocation context, tool calls, timing, skills, OpenTelemetry export, and token-cost visibility.

Can operators inspect the necessary request, response, tool, latency, and cost evidence for a production run?
Workflow analysis and dashboards

Run-aware workflow analysis plus customizable dashboard widgets powered by hidden workflows.

Are analysis reports and operational dashboards native, configurable, and connected to the workflow data you need?
Reusable agent skills

Portable SKILL.md capability bundles with optional tools that can be attached to agents.

Can teams package, govern, and reuse agent instructions and tools across workflows?
Runtime execution

Parallel DAG execution runs independent workflow nodes concurrently when their dependencies are ready.

How does the runtime schedule parallel branches, retries, long-running work, and failure handling?
