Let’s face it—building workflows can be a headache. Whether you’re automating simple tasks or orchestrating complex systems, juggling performance, flexibility, and extensibility feels like trying to balance on a unicycle while juggling flaming torches. Enter Uniflow, the high-performance workflow engine that’s here to save the day (and your sanity).

What is Uniflow?

Think of Uniflow as the ultimate workflow sidekick. It’s designed to handle everything from quick one-off jobs to long-running processes with ease. Need to route HTTP requests? Done. Want to dynamically tweak workflows on the fly without restarting anything? No problem. Looking to integrate third-party services or add custom logic? Uniflow has got you covered.

At its core, Uniflow is all about three things:

Performance: Blazing fast with minimal latency.
Flexibility: Change workflows in real-time to adapt to new needs.
Extensibility: Plug in new components or build your own extensions.

Why Should You Care?

Here’s the thing: most workflow tools are either too rigid or too complicated. Uniflow strikes the perfect balance—it’s powerful enough for pros but simple enough for beginners. Here are some cool use cases where Uniflow shines:

1. API Gateways Made Easy

Imagine building an API gateway without writing a single line of code. With Uniflow, you define listeners, routers, and snippets in YAML files, and boom—you’ve got yourself a fully functional API endpoint. For example, check out this super-basic /ping endpoint setup:

- kind: listener
  name: listener
  protocol: http
  port: '{{ .PORT }}'

Start it up, hit the endpoint, and voilà—it responds with “pong”! Perfect for microservices or testing APIs before diving into full-blown development.

2. Event-Driven Architectures

Got events flying around everywhere? Uniflow makes it easy to process them. Whether it’s webhooks, Kafka messages, or IoT sensor data, you can create workflows that listen, filter, transform, and act on these events seamlessly.

3. Custom Business Logic

Need to automate internal processes? Say goodbye to clunky scripts and hello to clean, readable workflows. For instance, you could set up a workflow to handle customer support tickets, escalate issues based on priority, and notify the right team—all within Uniflow.

4. Serverless Magic

Pair Uniflow with Kubernetes, and suddenly you’ve got a serverless powerhouse. Deploy workflows as CRDs (Custom Resource Definitions), and let Kubernetes manage scaling and resource allocation. It’s like having your own mini AWS Lambda, but tailored exactly how you want it.

How Does It Work?

Uniflow uses a node-based architecture. Each node represents a specific task—like listening for HTTP requests, routing traffic, or running custom code. Nodes connect via "ports," which pass data between them. This modular design means you can mix and match nodes to create virtually any workflow imaginable.

And don’t worry if you’re not a YAML wizard—Uniflow’s docs walk you through every step. Plus, there’s a handy CLI to help you start, stop, and debug workflows.

Give It a Spin!

Ready to see Uniflow in action? Here’s how to get started:

Install Go: Make sure you have Go 1.23 or later installed.

Test It Out:

curl localhost:8000/ping
pong

Run an Example:
Use the ping.yaml example to spin up a basic HTTP server:

./dist/uniflow start --from-specs ./examples/ping.yaml --env PORT=8000

Build It:

make init
make build

Clone the Repo:

git clone https://github.com/siyul-park/uniflow
cd uniflow

Pretty slick, huh?

Final Thoughts

Uniflow isn’t just another workflow engine—it’s a game-changer. Whether you’re a developer looking to streamline APIs, a DevOps engineer automating infrastructure, or a business analyst optimizing processes, Uniflow adapts to your needs without breaking a sweat.
