Nitro
Nitro is a high-efficiency C++ inference engine for edge computing. It is lightweight and embeddable, and can be used on its own within your own projects.
Troubleshooting
As Jan is in development mode, you might get stuck on a broken build.
To reset your installation:
-
Use the following commands to remove any dangling backend processes:
ps aux | grep nitro
Look for processes like "nitro" and "nitro_arm_64," and kill them one by one with:
kill -9 <PID>
-
Remove Jan from your Applications folder and Cache folder
make clean
This will remove all build artifacts and cached files:
- Delete Jan extension from your
~/jan/extensions
folder - Delete all
node_modules
in current folder - Clear Application cache in
~/Library/Caches/jan
- Delete Jan extension from your

Contributing
Contributions are welcome! Please read the CONTRIBUTING.md file
Pre-requisites
- node >= 20.0.0
- yarn >= 1.22.0
- make >= 3.81
Instructions
-
Clone the repository and prepare:
git clone https://github.com/janhq/jan cd jan git checkout -b DESIRED_BRANCH
-
Run development and use Jan Desktop
make dev
This will start the development server and open the desktop app.
-
(Optional) Run the API server without frontend
yarn dev:server
For production build
# Do steps 1 and 2 in the previous section
# Build the app
make build
This will build the app MacOS m1/m2 for production (with code signing already done) and put the result in dist
folder.
Docker mode
-
Supported OS: Linux, WSL2 Docker
-
Pre-requisites:
-
Docker Engine and Docker Compose are required to run Jan in Docker mode. Follow the instructions below to get started with Docker Engine on Ubuntu.

-
Option 1: Run Jan in CPU mode
# cpu mode with default file system docker compose --profile cpu-fs up -d # cpu mode with S3 file system docker compose --profile cpu-s3fs up -d
-
Option 2: Run Jan in GPU mode
-
Step 1: Check CUDA compatibility with your NVIDIA driver by running
nvidia-smi
and check the CUDA version in the outputnvidia-smi # Output +---------------------------------------------------------------------------------------+ | NVIDIA-SMI 531.18 Driver Version: 531.18 CUDA Version: 12.1 | |-----------------------------------------+----------------------+----------------------+ | GPU Name TCC/WDDM | Bus-Id Disp.A | Volatile Uncorr.

-
Step 2: Visit NVIDIA NGC Catalog and find the smallest minor version of image tag that matches your CUDA version (e.g., 12.1 -> 12.1.0)
-
Step 3: Update the
Dockerfile.gpu
line number 5 with the latest minor version of the image tag from step 2 (e.g. changeFROM nvidia/cuda:12.2.0-runtime-ubuntu22.04 AS base
toFROM nvidia/cuda:12.1.0-runtime-ubuntu22.04 AS base
) -
Step 4: Run command to start Jan in GPU mode
# GPU mode with default file system docker compose --profile gpu-fs up -d # GPU mode with S3 file system docker compose --profile gpu-s3fs up -d
-
This will start the web server and you can access Jan at http://localhost:3000
.
Note: RAG feature is not supported in Docker mode with s3fs yet.
