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.

Kestra is a workflow orchestration platform built around a simple idea: one engine for every team. Data engineers, infrastructure teams, and AI practitioners often end up maintaining separate tools that don't talk to each other. Kestra replaces that fragmentation with a single, declarative platform where all workflows live, run, and get monitored together.

Workflows are written in YAML, which means they're version-controlled, reviewable, and deployable through standard CI/CD pipelines. You don't have to rewrite existing code. Tasks can run in Python, Bash, Node.js, Go, or containers, so teams keep their existing logic and just wire it into Kestra's orchestration layer.

Key capabilities:

• 1400+ plugins covering cloud providers, databases, messaging systems, data tools (dbt, Airbyte, Spark), CI/CD, and SaaS services
• Event-driven and scheduled triggers including cron, webhooks, and message queue events, all handled by the same engine
• Built-in governance with retries, timeouts, SLAs, RBAC, and audit logs baked in, not bolted on
• Dual interface where developers work in code and non-engineers use the UI, both staying in sync
• API-first design so executions and workflow management can be automated or integrated into other systems
• AI workflow support for orchestrating RAG pipelines, model retraining, evaluation, and agent workflows with full observability

Compared to tools like n8n or Temporal, Kestra leans heavily on the declarative YAML approach and cross-team scope. It's not aimed at a single persona. The platform is designed so analysts can build workflows themselves without waiting on engineering, as JP Morgan Chase's team demonstrated when processing billions of rows across thousands of weekly API pulls.

Deployment options include self-hosted on Docker or Kubernetes, an Enterprise Edition with SSO, multi-tenancy, and hybrid/air-gapped support, and a managed Cloud offering. The open-source version is free with no time limit. Over 250 workflow blueprints are available to get started without building from scratch.
