Developer-first workflow UI toolkit for React

Your foundation for building workflow editors — fast.

Workflow Builder gives you a full front-end environment built with React, TypeScript, and React Flow.

Connect the SDK to your stack and ship custom workflow editors that look and behave like they were built in-house.

Your challenge

Every developer knows this pain:

You’re asked to build workflow features, but most of your time goes into wiring the basics — drag & drop, layout, state.

SaaS tools look tempting until you hit a wall with customization.

Stakeholders want results yesterday, but you’re buried in boilerplate instead of solving real product problems.

Building from scratch adds months of tech debt.

Buying SaaS means you’re stuck with a black box.

Neither feels like a win.

Workflow Builder gives you a third way: a front-end toolkit that does the boring part, stays open, and keeps you in control.

What you get

You don’t need to rebuild workflows from scratch. We’ve done the boring part.

Skip the boilerplate

Spin up a working editor in minutes. Ready-to-use nodes, edges, and auto-layout logic turn months of setup into days.

Back-end agnostic

Connect to your stack with zero lock-ins. REST APIs, databases, or AI pipelines — Workflow Builder adapts to whatever architecture you already run. No hidden dependencies. No forced hosting.

Full control

Own the code. White-label every layer — from UI to node behaviors — and extend modules freely. Workflows look and feel like your product, not someone else’s.

Plugin-first architecture

Extend functionality with a clean plugin system. Add new features or integrations without touching the core. Scalable, maintainable, future-proof.

Production-ready

Deploy on your own infrastructure with full control over security and compliance. Docs, quickstarts, and an open roadmap help you ship with confidence, at any scale.

Branding & design system

Style workflows to match your brand or your clients’. Our components, tokens, and themes connect directly to Figma — so exporting brand colors and assets takes seconds.

Easy node configuration

Add or tweak workflow objects without touching code. Your product or ops teams can expand the node palette through config, while you focus on actual development.

Key features

Production-ready workflow features out-of-the-box — powered by a plugin-first architecture for full extensibility.

  • Visual Workflow Canvas

    A scalable, infinite workspace for designing automation workflows using drag-and-drop interactions. Users can create, organize, and connect nodes visually without writing code, which accelerates implementation and improves clarity for both technical and non-technical users.

  • Node Library

    A ready-to-use set of workflow building blocks, including triggers, business actions, condition logic, branching rules, and time-delay elements. Each node can be extended, themed, or replaced with a custom component, enabling domain-specific automation editors.

  • Dynamic Properties Panel

    Every node and edge has a contextual configuration panel that automatically renders dynamic forms based on JSON schema. This allows teams to define data inputs, parameters, rules, and validation logic without modifying UI code — perfect for evolving products and multi-tenant systems.

  • Auto-Layout

    Organize diagrams automatically with auto-layout . Nodes and edges are positioned cleanly, even in complex flows. Supports multi-handle routing and label alignment — no manual adjustments required.

  • Smart Edge Routing –Avoiding Collision with Nodes

    Create structured, right-angled connections between nodes for maximum diagram readability. Orthogonal edges automatically route paths using horizontal and vertical segments, keeping workflows clean and easy to follow even as complexity grows. Especially useful for enterprise workflows where alignment and visual order matter.

  • Flow Runner

    The Flow Runner traverses the workflow graph and executes functions defined for each node type. It handles async operations (waiting for API calls, user input, timers), supports step-by-step execution with pause and resume, manages branching logic through decision and condition nodes, and propagates data between connected nodes.

  • Edge Reshaping

    Adjust and fine-tune orthogonal edge paths directly on the canvas using interactive handles. Users can reshape connections to avoid overlaps, improve readability, or align flows manually — all while preserving logic. Fully supports node rotation and grouped structures, enabling precise layout control in complex diagrams.

  • Auto-save Functionality

    Automatically persist workflow changes without interrupting the user experience. The system saves data in the background before the user exits the application, preventing accidental data loss. Supports both local storage and API-based persistence, making it suitable for prototypes as well as production-grade, multi-user environments.

  • Read-only Mode

    A dedicated viewing mode for users without edit permissions. All nodes and connections on the canvas are locked, preventing modifications while still allowing full inspection of node properties and workflow structure. Ideal for stakeholders, reviewers, and audit or approval scenarios.

  • Zoom In / Out

    Navigate workflows with precision at any scale. Users can zoom in for detailed editing or zoom out to understand the broader process structure. Zooming is controlled via dedicated UI actions, making it easy to work comfortably with both small diagrams and large, enterprise-level workflows.

HOW IT WORKS

4-step path

  • 01
    Download

    Download repository and embed it into your codebase.

  • 02
    Customize

    Configure your nodes library and JSON schema for properties to adapt to your use case, turn on or off required features.

  • 03
    Connect

    Connect the workflow output with the API or workflow engine of your choosing.

  • 04
    Deploy

    Run in your CI/CD, self-host on your infrastructure.

Figma logo

Build workflows faster with design-ready components.

Workflow Builder includes a production-ready React component system that mirrors the Figma Design Kit. Designers define the workflow visually, while developers implement the same components in code.

Transparent pricing

Think of licensing as buying engineering time back. While Community edition is free, the Enterprise is one predictable cost which replaces months of setup, scaffolding, and maintenance.

No per-seat surprises

No API call limits

No hidden meters

Just clean licensing that lets your team build, extend, and deploy without worrying about usage caps or scaling costs
