Python-first agentic DAG execution framework

AetherGraph

AetherGraph is a Python-first agentic DAG execution framework for building and orchestrating AI-powered workflows. It pairs a clean, function-oriented developer experience with a resilient runtime—event-driven waits, resumable runs, and pluggable services (LLM, memory, artifacts, RAG)—so you can start simple and scale to complex R&D pipelines.

Use AetherGraph to prototype interactive assistants, simulation/optimization loops, data transforms, or multi-step automations without boilerplate. It works with or without LLMs—bring your own tools and services, and compose them into repeatable, observable graphs.

• Examples

Requirements

• Python 3.10+
• macOS, Linux, or Windows
• (Suggested) LLM API keys (OpenAI, Anthropic, Google, etc.)
• (Optional) slack or telegram token. See Channel Setup
• (Optional UI) A modern browser to use the built-in AetherGraph web UI

---

Install

Option A — PyPI (recommended)

pip install aethergraph

Optional extras:

# Slack adapter
pip install "aethergraph[slack]"

# Dev tooling (linting, tests, types)
pip install "aethergraph[dev]"

The PyPI package ships with a prebuilt UI bundle, so /ui works out of the box when you run the server locally.

Option B — From source (editable dev mode)

git clone https://github.com/AIperture/aethergraph.git
cd aethergraph

# Base
pip install -e .

# With extras
echo "(optional)" && pip install -e ".[slack,dev]"

When running from source, the backend still works without the frontend bundle. If you want the built-in UI from source, you’ll need to build the frontend and copy the static bundle into aethergraph/server/ui_static/ (see the “UI Guide” in the docs).

---

Configure

Aethergraph can run without an LLM, but for many LLM-backed flows in examples, set keys via environment variables or a local secrets file.

Minimal example (OpenAI):

# .env (example)
AETHERGRAPH_LLM__ENABLED=true
AETHERGRAPH_LLM__DEFAULT__PROVIDER=openai
AETHERGRAPH_LLM__DEFAULT__MODEL=gpt-4o-mini
AETHERGRAPH_LLM__DEFAULT__API_KEY=sk-...your-key...

Or inline in a script at runtime (for on-demand key setting):

from aethergraph.runtime import register_llm_client

open_ai_client = register_llm_client(
    profile="my_llm",
    provider="openai",
    model="gpt-4o-mini",
    api_key="sk-...your-key...",
)

See the docs for setup of external channel methods (Slack, Telegram, etc.) for real-time interaction.

Where should .env live? In your project root (the directory where you run your Python entry point). You can override with AETHERGRAPH_ENV_FILE=/path/to/.env if needed.

Verify install

python -c "import aethergraph; print('AetherGraph OK, version:', getattr(aethergraph, '__version__', 'dev'))"

Run the built-in UI

AetherGraph ships with a small web UI that lets you:

• Browse and launch apps (click-to-run graphs)
• Chat with agents (graph-backed chat endpoints)
• Inspect runs, sessions, and artifacts

1. Define a simple project module

From your project root:

my_project/
  demos/
    __init__.py
    chat_demo.py
  aethergraph_data/   # workspace (created automatically as needed)

Example chat_demo.py:

# demos/chat_demo.py
from aethergraph import graphify

@graphify(
    name="chat_with_memory_demo",
    inputs=[],
    outputs=["turns", "summary"],
    as_app={
        "id": "chat_with_memory_demo",
        "name": "Chat with Memory",
    },
)
def chat_with_memory_demo():
    # Your graph implementation here – tools, nodes, etc.
    ...

as_app={...} tells AetherGraph to expose this graph in the App Gallery of the UI. You can also define graph_fn-based agents with as_agent={...} to appear in the Agent Gallery.

2. Start the server with UI from the terminal (recommended)

From my_project/:

aethergraph serve \
  --project-root . \
  --load-module demos \
  --reload

This will:

• Add . to sys.path so demos can be imported.
• Load any graphs/apps/agents defined in the demos module.
• Start the API + UI server on http://127.0.0.1:8745.
• Enable auto-reload: editing your graph files triggers a restart and reload.

You should see log lines like:

[AetherGraph] 🚀  Server started at:  http://127.0.0.1:8745
[AetherGraph] 🖥️  UI:                 http://127.0.0.1:8745/ui
[AetherGraph] 📡  API:                http://127.0.0.1:8745/api/v1/
[AetherGraph] 📂  Workspace:          ./aethergraph_data
[AetherGraph] ♻️  Auto-reload:        enabled

Then open in your browser:

• UI: http://127.0.0.1:8745/ui – App Gallery, Agent Gallery, runs, sessions, artifacts.
• API: http://127.0.0.1:8745/api/v1/ – for direct HTTP calls.

3. (Optional) Start the server from a Python script

If you prefer to embed the server in your own launcher:

# start_server.py
from aethergraph import start_server

if __name__ == "__main__":
    start_server(
        workspace="./aethergraph_data",
        project_root=".",
        load_module=["demos"],
        host="127.0.0.1",
        port=8745,
    )

python start_server.py

For active development, the CLI with --reload is recommended. start_server(...) is better when you want a simple “ship a server in my app” story.

For more details, see the UI Guide section in the docs (server setup, agents/apps, and common pitfalls).

Examples

Quick-start scripts live under examples/ in this repo.

Run an example:

cd examples
python hello_world.py

A growing gallery of standalone examples and recipes lives under:

• Repo: https://github.com/AIperture/aethergraph-examples

Troubleshooting

• ModuleNotFoundError: ensure you installed into the active venv and that your shell is using it.

• LLM/API errors: confirm provider/model/key configuration (env vars or your local secrets file).

• Windows path quirks: clear any local cache folders (e.g., .rag/) and re-run; verify write permissions.

• Slack extra: install with pip install "aethergraph[slack]" if you need Slack channel integration.

• UI shows no apps/agents:

  • Make sure your module (e.g. demos) is importable under --project-root.
  • Ensure at least one graph has as_app={...} or graph_fn has as_agent={...}.

---

Contributing (early phase)

• Use feature branches and open a PR against main.
• Keep public examples free of real secrets.
• Run tests locally before pushing.

Dev install:

pip install -e .[dev]
pytest -q
