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.

Metric	Flow-Like	Typical workflow engines
Execution speed	~244,000 workflows/sec	~200 workflows/sec
Latency per workflow	~0.6ms	~50-500ms
Engine	Rust (native compiled)	Python / Node.js (interpreted)

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).

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/TM9657/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.

❓ FAQ

Is Flow-Like free to use?
Most likely, yes. Flow-Like uses the Business Source License (BSL), which is free if your organization has fewer than 2,000 employees and less than $300M in annual recurring revenue. This covers startups, SMBs, and most enterprises. Read the full license.

Can I run it completely offline?
Yes, 100%. Flow-Like works fully offline on your local machine — ideal for air-gapped networks and secure environments. Switch to online mode anytime to collaborate.

Can I embed it in my product?
Yes. Flow-Like is white-label ready — embed the visual editor, customize the theme to your brand, integrate SSO, or run just the engine headlessly.

What languages can I use?
The visual builder is no-code. For custom nodes, you write Rust. SDKs and REST APIs are available for programmatic control.

Is it production-ready?
Flow-Like is actively developed and used in production. We recommend thorough testing for mission-critical workflows. See the releases page for version stability.

How do I get support?
Discord for quick help, Docs for guides, or GitHub Issues for bugs and features.
