copyright notice that is included in or attached to the work
(an example is provided in the Appendix below).
"Derivative Works" shall mean any work, whether in Source or Object
form, that is based on (or derived from) the Work and for which the
editorial revisions, annotations, elaborations, or other modifications

of this License, Derivative Works shall not include works that remain
separable from, or merely link (or bind by name) to the interfaces of,
the Work and Derivative Works thereof.
"Contribution" shall mean any work of authorship, including
the original version of the Work and any modifications or additions
to that Work or Derivative Works thereof, that is intentionally
submitted to Licensor for inclusion in the Work by the copyright owner
or by an individual or Legal Entity authorized to submit on behalf of
the copyright owner. For the purposes of this definition, "submitted"
means any form of electronic, verbal, or written communication sent
to the Licensor or its representatives, including but not limited to

2. Grant of Copyright License. Subject to the terms and conditions of
this License, each Contributor hereby grants to You a perpetual,
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
copyright license to reproduce, prepare Derivative Works of,
publicly display, publicly perform, sublicense, and distribute the
Work and such Derivative Works in Source or Object form.
3. Grant of Patent License. Subject to the terms and conditions of
this License, each Contributor hereby grants to You a perpetual,
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
(except as stated in this section) patent license to make, have made,
use, offer to sell, sell, import, and otherwise transfer the Work,
where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the
Work or Derivative Works thereof in any medium, with or without
modifications, and in Source or Object form, provided that You
meet the following conditions:
(a) You must give any other recipients of the Work or
Derivative Works a copy of this License; and
(b) You must cause any modified files to carry prominent notices
stating that You changed the files; and
(c) You must retain, in the Source form of any Derivative Works
that You distribute, all copyright, patent, trademark, and
attribution notices from the Source form of the Work,
excluding those notices that do not pertain to any part of
the Derivative Works; and
(d) If the Work includes a "NOTICE" text file as part of its
distribution, then any Derivative Works that You distribute must
include a readable copy of the attribution notices contained
within such NOTICE file, excluding those notices that do not
pertain to any part of the Derivative Works, in at least one
of the following places: within a NOTICE text file distributed
as part of the Derivative Works; within the Source form or
documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify
the terms of any separate license agreement you may have executed
with Licensor regarding such Contributions.
6. Trademarks. This License does not grant permission to use the trade
names, trademarks, service marks, or product names of the Licensor,
except as required for reasonable and customary use in describing the
origin of the Work and reproducing the content of the NOTICE file.
7. Disclaimer of Warranty. Unless required by applicable law or
agreed to in writing, Licensor provides the Work (and each
Contributor provides its Contributions) on an "AS IS" BASIS,
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
implied, including, without limitation, any warranties or conditions
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
PARTICULAR PURPOSE. You are solely responsible for determining the
appropriateness of using or redistributing the Work and assume any
risks associated with Your exercise of permissions under this License.
8. Limitation of Liability. In no event and under no legal theory,
whether in tort (including negligence), contract, or otherwise,
unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.

# Self-hosted AI starter kit
**Self-hosted AI Starter Kit** is an open, docker compose template that
quickly bootstraps a fully featured Local AI and Low Code development
environment.
This is Cole's version with a couple of improvements! Also,
the local RAG AI Agent workflow from the video will be automatically in your
n8n instance if you use this setup instead of the base one provided by n8n!
![n8n.io - Screenshot](https://raw.githubusercontent.com/n8n-io/self-hosted-ai-starter-kit/main/assets/n8n-demo.gif)
Curated by <https://github.com/n8n-io>, it combines the self-hosted n8n
platform with a curated list of compatible AI products and components to
quickly get started with building self-hosted AI workflows.
> [!TIP]
> [Read the announcement](https://blog.n8n.io/self-hosted-ai/)
### What’s included
✅ [**Self-hosted n8n**](https://n8n.io/) - Low-code platform with over 400
integrations and advanced AI components
✅ [**Ollama**](https://ollama.com/) - Cross-platform LLM platform to install
and run the latest local LLMs
✅ [**Qdrant**](https://qdrant.tech/) - Open-source, high performance vector
store with an comprehensive API
✅ [**PostgreSQL**](https://www.postgresql.org/) - Workhorse of the Data
Engineering world, handles large amounts of data safely.
### What you can build
⭐️ AI Agents which can schedule appointments
⭐️ Summarise company PDFs without leaking data
⭐️ Smarter slack bots for company comms and IT-ops
⭐️ Analyse financial documents privately and for little cost
## Installation
### For Nvidia GPU users
```
git clone https://github.com/n8n-io/self-hosted-ai-starter-kit.git
cd self-hosted-ai-starter-kit
docker compose --profile gpu-nvidia up
```
> [!NOTE]
> If you have not used your Nvidia GPU with Docker before, please follow the
> [Ollama Docker instructions](https://github.com/ollama/ollama/blob/main/docs/docker.md).
### For Mac / Apple Silicon users
If you’re using a Mac with an M1 or newer processor, you can't expose your GPU
to the Docker instance, unfortunately. There are two options in this case:
1. Run the starter kit fully on CPU, like in the section "For everyone else"
below
2. Run Ollama on your Mac for faster inference, and connect to that from the
n8n instance
If you want to run Ollama on your mac, check the
[Ollama homepage](https://ollama.com/)
for installation instructions, and run the starter kit as follows:
```
git clone https://github.com/n8n-io/self-hosted-ai-starter-kit.git
cd self-hosted-ai-starter-kit
docker compose up
```
After you followed the quick start set-up below, change the Ollama credentials
by using `http://host.docker.internal:11434/` as the host.
### For everyone else
```
git clone https://github.com/n8n-io/self-hosted-ai-starter-kit.git
cd self-hosted-ai-starter-kit
docker compose --profile cpu up
```
## ⚡️ Quick start and usage
The main component of the self-hosted AI starter kit is a docker compose file
pre-configured with network and disk so there isn’t much else you need to
install. After completing the installation steps above, follow the steps below
to get started.
1. Open <http://localhost:5678/> in your browser to set up n8n. You’ll only
have to do this once.
2. Open the included workflow:
<http://localhost:5678/workflow/srOnR8PAY3u4RSwb>
3. Select **Test workflow** to start running the workflow.
4. If this is the first time you’re running the workflow, you may need to wait
until Ollama finishes downloading Llama3.1. You can inspect the docker
console logs to check on the progress.
To open n8n at any time, visit <http://localhost:5678/> in your browser.
With your n8n instance, you’ll have access to over 400 integrations and a
suite of basic and advanced AI nodes such as
[AI Agent](https://docs.n8n.io/integrations/builtin/cluster-nodes/root-nodes/n8n-nodes-langchain.agent/),
[Text classifier](https://docs.n8n.io/integrations/builtin/cluster-nodes/root-nodes/n8n-nodes-langchain.text-classifier/),
and [Information Extractor](https://docs.n8n.io/integrations/builtin/cluster-nodes/root-nodes/n8n-nodes-langchain.information-extractor/)
nodes. To keep everything local, just remember to use the Ollama node for your
language model and Qdrant as your vector store.
> [!NOTE]
> This starter kit is designed to help you get started with self-hosted AI
> workflows. While it’s not fully optimized for production environments, it
> combines robust components that work well together for proof-of-concept
> projects. You can customize it to meet your specific needs
## Upgrading
### For Nvidia GPU users
```
docker compose --profile gpu-nvidia pull
docker compose create && docker compose --profile gpu-nvidia up
```
### For Mac / Apple Silicon users
```
docker compose pull
docker compose create && docker compose up
```
### For everyone else
```
docker compose --profile cpu pull
docker compose create && docker compose --profile cpu up
```

## Tips & tricks
### Accessing local files
The self-hosted AI starter kit will create a shared folder (by default,
located in the same directory) which is mounted to the n8n container and
allows n8n to access files on disk. This folder within the n8n container is
located at `/data/shared` -- this is the path you’ll need to use in nodes that
interact with the local filesystem.
