Flow-Like

If you can't see it, you can't trust it.
A Rust-powered workflow engine that runs on your device — laptop, server, or phone.
Fully typed. Fully traceable. Fully yours.

Flow-Like is a visual workflow automation platform that runs entirely on your hardware. Build workflows with drag-and-drop blocks, run them on your laptop, phone, or server, and get a clear record of where data came from, what changed, and what came out — no cloud dependency, no black boxes, no guesswork.

Why Flow-Like?

You decide where your workflows run. Not us.

Most workflow tools force you into their cloud. Your data leaves your machine, passes through third-party servers, and you're locked into their infrastructure. Offline? Stuck. Want to self-host? Pay enterprise prices.

Flow-Like runs wherever you choose — your laptop, your phone, your private server, or cloud infrastructure you control. Your data stays where you put it. No forced cloud dependency, no vendor lock-in, no "upgrade to enterprise for basic autonomy."

Local-first by default. Cloud-ready when you need it.

Automate on your couch without Wi-Fi. Deploy to your own AWS/GCP/Azure. Run in air-gapped factory networks. Process sensitive data in hospital environments. Your workflows, your infrastructure, your rules.

A Rust engine fast enough to run on a phone

The reason this works is raw performance. Flow-Like's engine is built in Rust — compiled to native code, no garbage collector, no runtime overhead. The same workflow that takes 500ms in a Node.js engine takes 0.6ms in Flow-Like.

That 1000x performance gap means real workflows can run on resource-constrained devices — phones, edge hardware, Raspberry Pis — not just beefy cloud servers. And on powerful machines, it means processing millions of executions without breaking a sweat.

Full visibility into every execution

Most workflow tools show a green checkmark and move on. You're left guessing where data came from and why the result looks the way it does.

Flow-Like workflows are fully typed — they track what data flows where and why. Every input, transformation, and output is recorded with complete lineage and audit trails.

• Data Origins — See exactly where each value came from: the API response, the file, the user input.
• Transformations — Every validation, enrichment, and reformatting step is visible and traceable.
• Clear Contracts — Type-safe input/output definitions catch errors before deployment, not in production.
• Three Perspectives — Process view for business, Data view for analysts, Execution view for engineers. Same workflow, different lenses.

And everything else

• AI-Native — Run LLMs locally or in the cloud with guardrails, approval gates, and full execution tracing on every call.
• White-Label Ready — Embed the editor in your product. Your logo, your colors, your brand. SSO, usage metering, and per-tenant scoping included.
• Source Available — BSL license, free for the vast majority of users (<2,000 employees and <$300M ARR).

How it compares

Quick Start

The Ecosystem

🎨 Visual Workflow Studio

A no-code IDE for building workflows. Smart wiring with type-aware pins, inline execution feedback, live validation, and snapshot-based debugging.

🧩 900+ Built-in Nodes

APIs & webhooks, databases, file processing (Excel, CSV, PDF), AI models & computer vision, messaging (Slack, Discord, email), IoT, logic & control flow, security & auth — and growing.

→ Explore the Node Catalog

🤖 AI-Powered Workflows

Download and run LLMs, vision models, and embeddings locally or in the cloud. Every AI decision is logged with full context — inputs, outputs, model version, and reasoning trace.

📦 Apps & Templates

Package workflows as shareable applications with built-in storage. Run them offline or in the cloud. Browse the template store or share your own.

Who it's for

Build from Source

# Prerequisites: mise, Rust, Bun, Tauri prerequisites, Protobuf compiler
# Full guide: https://docs.flow-like.com/contributing/getting-started/

git clone https://github.com/Rheosoph/flow-like.git
cd flow-like
mise trust && mise install   # install toolchains (Rust, Bun, Node, Python, uv)
bun install                  # install Node packages
mise run build:desktop       # production build

All dev / build / deploy tasks are defined in the root mise.toml. Run mise tasks to see every available task, or mise run <task> to execute one:

mise run dev:desktop:mac:arm   # dev mode – macOS Apple Silicon
mise run dev:web               # dev mode – Next.js web app
mise run build:desktop         # production desktop build
mise run fix                   # auto-fix lint (clippy + fmt + biome)
mise run check                 # run all checks without fixing

💡 Platform-specific hints for macOS, Windows, and Linux are in the docs.

White-Label & Customization

Embed the visual editor in your application, or run the engine headlessly behind the scenes.

• Themes — Catppuccin, Cosmic Night, Neo-Brutalism, Soft Pop, Doom, or create your own
• Design Tokens — Map your brand palette with dark/light mode support
• SSO — OIDC/JWT with scoped secrets per tenant
• Usage Metering — Per-tenant quotas, event tracking, audit trails
• SDKs & APIs — Control workflows programmatically

🔌 SDKs

Integrate Flow-Like into your applications with official SDKs:

Both SDKs support workflows, file management, LanceDB, chat completions, embeddings, and optional LangChain integration. → SDK Docs

Perfect for SaaS platforms, internal tools, client portals, and embedded automation.
