# Share an Opik Eval Report — Comet's LLM Traces at a Plain URL

> Opik stores traces and eval results in a Comet workspace. Export the experiment rows to HTML and publish them to Comma so reviewers without a workspace can read and comment on them.

# Share an Opik eval report

Opik gives you traces, datasets and scored experiments, and keeps all of it in
a Comet workspace or a self-hosted instance. Both are places a reviewer from
outside your team does not have access to.

## Export the experiment items

```python
import pandas as pd
from opik import Opik

client = Opik()
experiment = client.get_experiment_by_name("support-answers-v3")

rows = []
for item in experiment.get_items():
    rows.append({
        "input": item.dataset_item_data.get("question"),
        "output": item.evaluation_task_output.get("output"),
        **{s["name"]: s["value"] for s in (item.feedback_scores or [])},
    })

pd.DataFrame(rows).to_html("opik.html", index=False, float_format="%.3f", escape=True)
```

Then publish it:

```bash
curl -fsS -X PATCH "https://commareports.com/api/v1/reports/$REPORT_ID" \
  -H "Authorization: Bearer $COMMA_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d "$(jq -n --rawfile html opik.html \
        --arg title "Support answers v3" '{title: $title, html: $html}')"
```

## Why the link matters

- **Anchored threads** — the judgment call sits on the row, not in Slack. See
  [commenting on HTML](/comment-on-html).
- **Revisions** — one report id per suite; every run is kept.
- **Access per report** — private, team-only, or domain-gated. See the
  [sharing model](/docs/sharing).

## Close the loop with the agent

An agent can read the review back through [the MCP server](/docs/mcp) and
update the dataset or the prompt —
[give an agent feedback](/agents/give-an-agent-feedback).

## Limits

- **Entry HTML: 5 MB.** Truncate long outputs or export per scorer.
- **Assets: 25 MB per file, 250 MB and 500 files per report.**
- **60 requests/minute per token.**

## Try it

Comma is free — unlimited reports, unlimited commenters, unlimited revision
history.
