About Cincha

Cincha.dev is for builders.

A Cincha app is a virtual environment running a harness ( Pi ) and scaffolding ( the Cinch for your harness ) written in Python.

Scaffolding gives agents native Python tools to connect to services and complete tasks. These agents are powerful, but sharing them with the right setup especially with non-technical people, is difficult.

Hello World!

hello.py

def greet(name: str = "there") -> str:
    """Return a friendly greeting."""
    from hello_impl import render_greeting

    return render_greeting(name)

pi · deepseek-v4-flash

› Hello

◌ Thinking...

◆ bash

python -c "from hello import greet; print(greet('world'))"

Hello, world! From the _hello app.

Hey Dev User! 👋 The launch loop works. Manifest loaded, the bundle launched, and the turn streamed back.

Cincha.dev solves this problem by letting you ship a harness to a coworker, friend, or fellow builder on the web in a form they can extend. You can ship a harness with data connectors set up and ready to go or let users connect their own data. If you prefer, you can download the whole thing as a ZIP file and run on it locally with pi.

You can create a Cincha app with the app builder, a Cincha designed to produce Cinchas. Simply define what you are building: the right Python packages, data connectors and a default model. Then grab the zip and upload to create a new Cincha app.

Cincha uses OpenRouter as its LLM provider, allowing you to choose any model you want. We charge a 10% fee on OpenRouter token costs.

We are committed to making Cincha.dev a company that gives value back to our users and to the builders who make it possible.
