skeino

A reusable, embeddable replacement for the langgraph dev HTTP server.

📖 Full documentation: https://ranjitjana027.github.io/skeino/

skeino exposes the LangGraph Studio-compatible REST surface (threads, runs, streaming, assistants) over any user-supplied LangGraph graph. It is built to be:

Modular — api, ops, persistence, streaming, serialization are separate concerns with explicit dependencies.
Pluggable — checkpointers register themselves via a small decorator-based registry; Postgres and in-memory ship out of the box, Redis / Mongo / etc. can be added without touching skeino core.
Two entry points — programmatic create_app(graphs={...}) and a high-level from_langgraph_json("langgraph.json") loader.

Install

pip install skeino

Quickstart

# Programmatic
from skeino import create_app, SkeinoSettings
from my_project.graph import graph

app = create_app(
    graphs={"my_agent": graph},
    settings=SkeinoSettings(
        checkpointer_scheme="postgres",  # pip install 'skeino[postgres]'
        checkpointer_uri="postgresql://...",
    ),
)

# langgraph.json driven
from skeino import from_langgraph_json
app = from_langgraph_json("langgraph.json")

Run with uvicorn:

uvicorn app:app --reload --port 8000
