Nyno 3.0: Open-Source Backend for Workflow-based AGI. Extend with Python, PHP, JS and Ruby. Route with YAML.
Nyno is an open-source multi-language workflow engine and language that lets you build, extend, and connect automation in the languages you already know — Python, PHP, JavaScript, and Ruby.
Each programming language runs in its own high-performance worker engine. Command-steps can be called in human-readable YAML Workflows (.nyno files).
To achieve most requests/per second we're using multi-process worker engines where feasible. Nyno will spawns 2 light-weight workers for each language in dev mode or 3 workers for every language and CPU core in prod mode. This means that if you have 4 CPU cores, it will spawn 12 ready-to-run workers to run workflow steps.
In Nyno, every Python, JavaScript, PHP and Ruby script becomes a reusable command that runs in its own high-performing worker engine. Just export a function (with args and context) and call it in any workflow using plain YAML text.
Example (JavaScript)
// extensions/hello/command.js
export function hello(args, context) {
const name = args[0] || "World";
context['hello'] = `Hello, ${name}!`;
return 0;
}Example in Workflow (YAML):
Example in TCP (after saving your flow.json in workflows-enabled/ and restarting Nyno):
tcpman localhost:9024/test_nyno 'c{"apiKey":"changeme"}' 'q{"name":"Alice"}'Example output
>>> Sending: c{"apiKey":"changeme"}
{"status":"ok","type":"connect"}
>>> Sending: q{"name":"Alice","path":"/test_nyno"}

git clone https://github.com/empowerd-cms/nyno
cd nyno./build-container.sh "podman" # or use dockerMake sure you to build the container first.
./run-container-prod.sh "podman" # or use docker, GUI at http://localhost:9057
Note: Nyno is dependent on Best.js which needs to be installed to run Nyno. You will need to install quite a lot of dependencies. Docker/Podman install is recommended. However, for the experts, a bash scripts/check_host.sh script is included to check dependencies quickly.
# install Best.js
git clone https://github.com/empowerd-cms/best.js
cd best.js
npm install # or # bun install
npm link # for "bestjsserver" command
cd ../
# install Nyno
git clone https://github.com/empowerd-cms/nyno
cd nyno
npm install # or # bun install
# Optionally check system status/dependencies (Python, PHP Swoole, Ruby, Node,Postgres)
bash scripts/check_host.sh
# Execute Nyno
bash run-dev.sh # runs Nyno in dev mode
Example Python extension:
# extensions/hello-py/command.py
def hello_py(args, context):
name = args[0] if args else "World"
context["hello-py"] = f"Hello, {name} from Python!"
return 0Example PHP extension:
<?php
// extensions/hello-php/command.php
function hello_php($args, &$context) { // & required to modify context
$name = $args[0] ?? "World";
$context["hello-php"] = "Hello, $name from PHP!";
return 0;
}Example using context to Pass Data Between Steps
export function some_extension(args, context) {
const result = args[0] || "default value";
// Save output in context for the next step
context['MY_RESULT'] = result;
return 0; // default path
