How It Works

Build APIs visually. Choose where they run — cloud or your infrastructure.

1

Create Blocks

Drag blocks on an infinite canvas. Write JavaScript to call APIs, transform data, or run custom logic.

→
2

Connect & Chain

Link blocks together visually. Output flows to input. Build multi-step workflows in minutes.

→
3

Choose Execution

Run in the cloud for speed, or use SignalR blocks to execute on your own servers — access internal systems securely.

→
4

Deploy as API

One click to publish. Get a production URL with custom domain, API keys, and full request logging.

Need On-Premise Access? SignalR Hybrid Execution

Access internal databases, legacy systems, or sensitive data — blocks execute on your infrastructure while you design in the cloud.
No VPN. No firewall rules. No exposed ports. Just a simple outbound connection.

SignalR real-time architecture

Real-time communication between your dashboard and local runners

📦

One-Click Runner Setup

Download a ready-to-run .NET template. Pre-configured with SignalR client, authentication, and logging. Just dotnet run — your runner connects instantly.

🖥️

Full Local Access

Run PowerShell scripts, show Windows notifications, access local databases, control hardware, read files — anything your machine can do, triggered from the cloud.

📝

Full Logging

All logs from your local runner are captured and visible in the dashboard. Input, output, and custom logs — everything is tracked.
