S S Flow by Skyris Innovations

Workflow automation, with an API built in.

S Flow connects your systems. Schedules and API calls start flows that call web services, query databases and run code, on a server you control.

Visual flows

Build flows from nodes: HTTP requests, SQL Server and PostgreSQL queries, code, switches and subflows, with a full history of every run.

Documented APIs

Every workspace is an API: endpoints with path parameters, request validation, API keys, rate limits and a live API reference.

Runs where you need it

One self-contained server for Windows or Linux, on your own machine or in the cloud. Nothing else to install.
