Flowise exposes a REST API and SDK for programmatic interaction with flows and agents, enabling integration into existing CI/CD pipelines or application backends. The platform supports self-hosting on-premises or on any cloud provider, giving teams full infrastructure control. Key integration touchpoints include:
- Orchestration frameworks: LangChain, LlamaIndex
- Vector databases: Milvus (and 100+ other supported DBs)
- Cloud AI: AWS Bedrock
- Messaging/productivity: Slack, Notion, Telegram
- Observability stack: Prometheus metrics endpoint, OpenTelemetry tracing for full execution traces
Workflows support both single-agent and multi-agent topologies, with human-in-the-loop nodes for approval or intervention steps. The Embedded Chat widget can be dropped into any web frontend. Pricing tiers gate Prediction volume (100/month free → 10,000/month Starter → 50,000/month Pro) and storage (5MB → 1GB → 10GB), while the open-source self-hosted path removes cloud-tier restrictions.
