Jaseci Studio

Developer workbench for building, testing, and operating Jac applications. Built entirely in Jac using jac-client for the full-stack experience — backend walkers and frontend UI in one language.

Quick Start

pip install jaseci
cd your-jac-project
jac start main.jac
# -> http://localhost:8000/

Studio ships as part of any Jac application. All Studio pages are available alongside your app's routes.

Development

git clone https://github.com/jaseci-labs/jaseci-studio
cd jaseci-studio
jac build
jac start main.jac --port 8001

inspect_graph	Graph structure for visualization (filters out Studio nodes)
update_node_props	Edit node properties inline
get_server_logs	Captured server log entries
list_packages / install_package	Browse & install jacpacks
load_example_app	Seed example Todo tasks
list_tasks / add_task / toggle_task / delete_task	Example app walkers
