What it does

Open‑Flow lets you design, version‑control, and run visual TypeScript workflows on your own server.

When to use it
  • •You need a repeatable data‑pipeline (e.g., fetch‑transform‑store) that non‑developers can see and edit.
  • •Your product requires custom automation that must stay inside your VPC for security or compliance.
  • •You want a low‑code UI for business users while keeping the logic in real TypeScript that lives in your repo.
Ready-to-paste prompt
npx open-flow@latest run --file workflow.ts --step fetchUser --output json
Heads up: Open‑Flow requires Node 18+ and the `ts-node` package; if you run the Docker compose file, make sure the host’s Docker engine has at least 2 GB RAM allocated, otherwise the isolated TypeScript sandbox will crash at startup.

How open-flow works
Codeflow
Free to inspect

Open-flow is a very large TypeScript project (~181k lines across 1021 code files, plus 157 test files). Setup is light: installs like a normal app. Reading the code is optional. Last commit this month, Apache-2.0 license, has a test suite.
