## Which one, for what

### DeepEval (B)

Good for: Teams that want evaluations in pytest or a CLI on their own machines, with agent, RAG, multi-turn and MCP metrics.

Ahead on:
- Reliability, 59 against 18
- Security & auth, 47 against 33
- Payments & pricing, 60 against 20
- Maintenance & community, 83 against 74
- Transparency & trust, 63 against 53

Also in its favour:
- Free to start without a card
- Open source

Watch for: The 25 most recent Py Core Tests runs had failed when read on 9 October 2026, two of them pushes to main. Issue #3372 of 26 September reports the same

### Galileo API + MCP (D)

Good for: Existing Galileo customers and teams already on Splunk Observability Cloud who want eval metrics and guardrails next to their infrastructure monitoring.

Also in its favour:
- A hosted endpoint, with nothing to install

Watch for: No status page, no published rate limits and no SLA

## Verdicts

**DeepEval.** DeepEval runs evaluations and tracing locally under Apache 2.0 with no account, and writes each test run to JSON or SQLite. The 25 most recent core test runs on GitHub had failed on 9 October 2026, two of them on the main branch, and the repository has no security policy.

**Galileo API + MCP.** OpenAPI 3.1 spec with 184 paths and 244 operations. No status page, no published rate limits and no SLA.

## Before you call either

### DeepEval

1. Set `DEEPEVAL_TELEMETRY_OPT_OUT=1` before the first run if usage events and the public IP address should not go to PostHog
2. Set a judge model key such as `OPENAI_API_KEY`, or use the non-LLM metrics. Most metrics call an LLM judge and bill the owner's provider account
3. Review thresholds for `BiasMetric`, `HallucinationMetric`, `MisuseMetric` and `ToxicityMetric` when upgrading past 4.2.0. Higher scores now mean better
4. Read results from `.deepeval/.latest_run_full.json` or a `results_folder`. `deepeval inspect` opens a terminal interface meant for a person
5. Pass an existing key with `deepeval login --api-key` in CI. Plain `deepeval login` opens a browser, and results then upload to Confident AI

### Galileo API + MCP

1. Check which side the account lives on first. Pre-August Galileo accounts use api.galileo.ai, Splunk SaaS accounts use app.{realm}.observability.splunkcloud.com/ao/api/
2. Send the key as `Splunk-AO-API-Key`. The current spec no longer lists `Galileo-API-Key`
3. Page list endpoints with `limit` and `starting_token`
4. Use the error catalogue's retriable flag to decide whether to retry. 429s carry no documented `Retry-After`
5. Use the REST API to read traces. The MCP server mostly creates datasets and prompts
