- **LLM Evaluation**: Datasets, experiments, and LLM-as-a-judge metrics for hallucination detection, moderation, and RAG assessment.
- **Prompt & Agent Optimization**: The Opik Agent Optimizer SDK to improve prompts and agents.
- **Production-Ready Monitoring**: Scalable dashboards and online evaluation rules.
- **Opik Guardrails**: Features to help you implement safe and responsible AI practices.
- **CI/CD Evaluation**: A PyTest integration to test LLM pipelines on every commit.
<br>
Key capabilities include:
- **Development & Tracing:**
- Track all LLM calls and traces with detailed context during development and in production ([Quickstart](https://www.comet.com/docs/opik/quickstart/?from=llm&utm_source=opik&utm_medium=github&utm_content=quickstart_link&utm_campaign=opik)).
- Extensive 3rd-party integrations for easy observability: Seamlessly integrate with a growing list of frameworks, supporting many of the largest and most popular ones natively (including recent additions like **Google ADK**, **Autogen**, and **Flowise AI**). ([Integrations](https://www.comet.com/docs/opik/integrations/overview/?from=llm&utm_source=opik&utm_medium=github&utm_content=integrations_link&utm_campaign=opik))
- Annotate traces and spans with feedback scores via the [Python SDK](https://www.comet.com/docs/opik/tracing/advanced/annotate_traces/#annotating-traces-and-spans-using-the-sdk?from=llm&utm_source=opik&utm_medium=github&utm_content=sdk_link&utm_campaign=opik) or the [UI](https://www.comet.com/docs/opik/tracing/advanced/annotate_traces/#annotating-traces-through-the-ui?from=llm&utm_source=opik&utm_medium=github&utm_content=ui_link&utm_campaign=opik).
- Experiment with prompts and models in the [Prompt Playground](https://www.comet.com/docs/opik/development/prompt-playground).
- **Evaluation & Testing**:
- Automate your LLM application evaluation with [Datasets](https://www.comet.com/docs/opik/evaluation/advanced/manage_datasets/?from=llm&utm_source=opik&utm_medium=github&utm_content=datasets_link&utm_campaign=opik) and [Experiments](https://www.comet.com/docs/opik/evaluation/advanced/evaluate_your_llm/?from=llm&utm_source=opik&utm_medium=github&utm_content=eval_link&utm_campaign=opik).
- Leverage powerful LLM-as-a-judge metrics for complex tasks like [hallucination detection](https://www.comet.com/docs/opik/evaluation/metrics/hallucination/?from=llm&utm_source=opik&utm_medium=github&utm_content=hallucination_link&utm_campaign=opik), [moderation](https://www.comet.com/docs/opik/evaluation/metrics/moderation/?from=llm&utm_source=opik&utm_medium=github&utm_content=moderation_link&utm_campaign=opik), and RAG assessment ([Answer Relevance](https://www.comet.com/docs/opik/evaluation/metrics/answer_relevance/?from=llm&utm_source=opik&utm_medium=github&utm_content=alex_link&utm_campaign=opik), [Context Precision](https://www.comet.com/docs/opik/evaluation/metrics/context_precision/?from=llm&utm_source=opik&utm_medium=github&utm_content=context_link&utm_campaign=opik)).
- Integrate evaluations into your CI/CD pipeline with our [PyTest integration](https://www.comet.com/docs/opik/evaluation/overview/?from=llm&utm_source=opik&utm_medium=github&utm_content=pytest_link&utm_campaign=opik).
- **Production Monitoring & Optimization**:

- Monitor feedback scores, trace counts, and token usage over time in the [Opik Dashboard](https://www.comet.com/docs/opik/tracing/dashboards/production_monitoring/?from=llm&utm_source=opik&utm_medium=github&utm_content=dashboard_link&utm_campaign=opik).
- Utilize [Online Evaluation Rules](https://www.comet.com/docs/opik/production/online-evaluation/rules/?from=llm&utm_source=opik&utm_medium=github&utm_content=dashboard_link&utm_campaign=opik) with LLM-as-a-Judge metrics to identify production issues.
- Leverage **Opik Agent Optimizer** and **Opik Guardrails** to continuously improve and secure your LLM applications in production.
**Who it's for:** ML engineers building LLM-powered agents, AI teams moving from prototype to production, and engineering teams that need open-source, self-hostable observability they can run in their own environment.
> **Why open source matters here:** Opik is Apache-2.0 licensed and free to self-host: the full platform, backend included, not just a client SDK. The repository includes the server backend, web application, tracing, datasets, experiments, evaluations, prompt management, online evaluation, and agent optimization components, all under Apache-2.0. You can run LLM observability inside your own infrastructure with no data leaving your environment and no Enterprise sales conversation required.

<a id="-quick-start"></a>
## ⚡ Quick Start
Install the Python SDK and configure it:
```bash
pip install opik
opik configure
```
Wrap any function with the `@track` decorator to start logging traces:
```python
from opik import track
@track
def my_function(input: str) -> str:
return input
```
Every call to `my_function` is now logged to Opik, including nested calls, so this works for full agent and pipeline traces, not just single LLM calls. See the [Quickstart guide](https://www.comet.com/docs/opik/quickstart?from=llm&utm_source=opik&utm_medium=github&utm_content=quickstart_hero_link&utm_campaign=opik) for the TypeScript SDK and other setup options.
### Connect your coding agent
Let Claude Code, Cursor, VS Code Copilot, Codex or opencode read your traces, score outputs and run evaluations from chat. One command sets it up. It needs [`uv`](https://docs.astral.sh/uv/) and no SDK:
```bash
uvx opik mcp configure
```
[](https://cursor.com/en/install-mcp?name=opik-mcp&config=eyJ1cmwiOiJodHRwczovL3d3dy5jb21ldC5jb20vb3Bpay9hcGkvdjEvbWNwIn0%3D)
[](https://insiders.vscode.dev/redirect/mcp/install?name=opik-mcp&config=%7B%22type%22%3A%22http%22%2C%22url%22%3A%22https%3A%2F%2Fwww.comet.com%2Fopik%2Fapi%2Fv1%2Fmcp%22%7D)
The badges and the `add-mcp` fallback below target Opik Cloud; the command above also handles self-hosted deployments. Other MCP clients on Opik Cloud: `npx add-mcp https://www.comet.com/opik/api/v1/mcp --name opik-mcp`. Details, troubleshooting and FAQ are in the [MCP server guide](https://www.comet.com/docs/opik/mcp-server?utm_source=opik&utm_medium=github&utm_content=mcp_quickstart_link&utm_campaign=opik).

## 🛠️ Opik Server Installation
Get your Opik server running in minutes. Choose the option that best suits your needs:
### Option 1: Comet.com Cloud (Easiest & Recommended)
Access Opik instantly without any setup. Ideal for quick starts and hassle-free maintenance.
👉 [Create your free Comet account](https://www.comet.com/signup?from=llm&utm_source=opik&utm_medium=github&utm_content=install_create_link&utm_campaign=opik)
### Option 2: Self-Host Opik for Full Control
Deploy Opik in your own environment. Choose between Docker for local setups or Kubernetes for scalability.
#### Self-Hosting with Docker Compose (for Local Development & Testing)
This is the simplest way to get a local Opik instance running. Note the new `./opik.sh` installation script:
On Linux or Mac Environment:
```bash
# Clone the Opik repository
git clone https://github.com/comet-ml/opik.git
# Navigate to the repository
cd opik
# Start the Opik platform
./opik.sh
```
On Windows Environment:
```powershell
# Clone the Opik repository
git clone https://github.com/comet-ml/opik.git
# Navigate to the repository
cd opik
# Start the Opik platform
powershell -ExecutionPolicy ByPass -c ".\\opik.ps1"
```
**Installation Script Options**
The `opik.sh` and `opik.ps1` scripts support the following options:
```bash
# Start full Opik suite (default behavior)
./opik.sh
# Start only infrastructure services (databases, caches etc.)
./opik.sh --infra
# Start infrastructure + backend services
./opik.sh --backend
# Enable guardrails with any profile
./opik.sh --guardrails # Guardrails with full Opik suite
./opik.sh --backend --guardrails # Guardrails with infrastructure + backend
# Build the containers from source before starting
./opik.sh --build
# Check that all containers are healthy
./opik.sh --verify
# Stop all containers
./opik.sh --stop
# Stop all containers and remove all Opik data volumes
# WARNING: ALL OPIK DATA WILL BE LOST
./opik.sh --clean
# Show all available options
./opik.sh --help
```
Use the `--help` or `--info` options to troubleshoot issues. Dockerfiles now ensure containers run as non-root users for enhanced security. Once all is up and running, you can now visit [localhost:5173](http://localhost:5173) on your browser!

## 💻 Opik Client SDK
Opik provides a suite of client libraries and a REST API to interact with the Opik server. This includes SDKs for Python and TypeScript, plus first-party [OpenTelemetry](https://www.comet.com/docs/opik/tracing/opentelemetry/overview?from=llm&utm_source=opik&utm_medium=github&utm_content=otel_link&utm_campaign=opik) support: any language with an OpenTelemetry SDK — including [Java](https://www.comet.com/docs/opik/integrations/spring-ai?from=llm&utm_source=opik&utm_medium=github&utm_content=java_link&utm_campaign=opik), [Ruby](https://www.comet.com/docs/opik/integrations/opentelemetry-ruby-sdk?from=llm&utm_source=opik&utm_medium=github&utm_content=ruby_link&utm_campaign=opik), and .NET — can send traces to Opik. For detailed API and SDK references, see the [Opik Client Reference Documentation](https://www.comet.com/docs/opik/reference/overview?from=llm&utm_source=opik&utm_medium=github&utm_content=reference_link&utm_campaign=opik).
### Python SDK Quick Start
To get started with the Python SDK:
Install the package:
```bash
# install using pip
pip install opik
# or install with uv
uv pip install opik
```
Configure the python SDK by running the `opik configure` command, which will prompt you for your Opik server address (for self-hosted instances) or your API key and workspace (for Comet.com):
```bash
opik configure
```
> [!TIP]
> You can also call `opik.configure(use_local=True)` from your Python code to configure the SDK to run on a local self-hosted installation, or provide API key and workspace details directly for Comet.com. Refer to the [Python SDK documentation](https://www.comet.com/docs/opik/python-sdk-reference/?from=llm&utm_source=opik&utm_medium=github&utm_content=python_sdk_docs_link&utm_campaign=opik) for more configuration options.
You are now ready to start logging traces using the [Python SDK](https://www.comet.com/docs/opik/python-sdk-reference/?from=llm&utm_source=opik&utm_medium=github&utm_content=sdk_link2&utm_campaign=opik).

> [!TIP]
> If the framework you are using is not listed above, feel free to [open an issue](https://github.com/comet-ml/opik/issues) or submit a PR with the integration.
If you are not using any of the frameworks above, you can also use the `track` function decorator to [log traces](https://www.comet.com/docs/opik/tracing/advanced/log_traces/?from=llm&utm_source=opik&utm_medium=github&utm_content=traces_link&utm_campaign=opik):
```python
import opik
opik.configure(use_local=True) # Run locally
@opik.track
def my_llm_function(user_question: str) -> str:
# Your LLM code here
return "Hello"
```
> [!TIP]
> The track decorator can be used in conjunction with any of our integrations and can also be used to track nested function calls.

### 🧑⚖️ LLM as a Judge metrics
The Python Opik SDK includes a number of LLM as a judge metrics to help you evaluate your LLM application. Learn more about it in the [metrics documentation](https://www.comet.com/docs/opik/evaluation/metrics/overview/?from=llm&utm_source=opik&utm_medium=github&utm_content=metrics_2_link&utm_campaign=opik).
To use them, simply import the relevant metric and use the `score` function:
```python
from opik.evaluation.metrics import Hallucination
metric = Hallucination()
score = metric.score(
input="What is the capital of France?",
output="Paris",
context=["France is a country in Europe."]
)
print(score)
```
Opik also includes a number of pre-built heuristic metrics as well as the ability to create your own. Learn more about it in the [metrics documentation](https://www.comet.com/docs/opik/evaluation/metrics/overview?from=llm&utm_source=opik&utm_medium=github&utm_content=metrics_3_link&utm_campaign=opik).

### 🔍 Evaluating your LLM Applications
Opik allows you to evaluate your LLM application during development through [Datasets](https://www.comet.com/docs/opik/evaluation/advanced/manage_datasets/?from=llm&utm_source=opik&utm_medium=github&utm_content=datasets_2_link&utm_campaign=opik) and [Experiments](https://www.comet.com/docs/opik/evaluation/advanced/evaluate_your_llm/?from=llm&utm_source=opik&utm_medium=github&utm_content=experiments_link&utm_campaign=opik). The Opik Dashboard offers enhanced charts for experiments and better handling of large traces. You can also run evaluations as part of your CI/CD pipeline using our [PyTest integration](https://www.comet.com/docs/opik/evaluation/overview/?from=llm&utm_source=opik&utm_medium=github&utm_content=pytest_2_link&utm_campaign=opik).
