- BotGauge, good for A team that wants adversarial testing of a tool-calling agent before release, with traces and AI-judge evals in the same place, and that is outside the countries the terms exclude. Ahead on Security & auth, 56 against 40. Also A hosted endpoint, with nothing to install.
- MLflow Tracing, good for Teams that already run MLflow or want Apache-2.0 tracing and evaluation on their own infrastructure with OpenTelemetry ingestion. Ahead on Reliability, 76 against 18; Schema & documentation, 78 against 53; Agent ergonomics, 72 against 55; Payments & pricing, 60 against 10; Maintenance & community, 88 against 67. Also Runs on your own machine; Open source.

Why the edge:
- Reliability, MLflow Tracing +58: BotGauge 18 (No status page. status.botgauge.com doesn't resolve and neither the site nor the docs link one (0). With no history to read, 5. No request rate limits for ingest or the eval API. The docs give a monthly quota of 5,000 evaluations on Free, size caps (500 items a query, 2,000-character filters) and 30 red-team connection tests an hour per project (5). No 429 or Retry-After guidance. `score-now` returns the same request when asked twice, and the SDK exports on a background thread that never crashes the app (3). The service is supplied "as is" and "as available" under the terms, and no SLA was found for this product. The 99.9 per cent SLA on the /ai-agents page belongs to the QA service (0). The service isn't labelled beta, but the SDK is 0.x, marked "4 - Beta" on PyPI, and the docs say API shapes may change before 1.0 (5). 0+5+5+3+0+5 = 18.); MLflow Tracing 76 (Scored on the local-software lines, since MLflow runs where the owner installs it. Official `mlflow` and `mlflow-tracing` packages on PyPI with Python 3.10 or later stated, and the MCP server behind the `mlflow[mcp]` extra (20). Public CI in GitHub Actions. Of 28 recent runs of the test workflow read on 9 October, 13 passed, 5 failed, 8 were cancelled and 2 were running, all on pull requests, so the state of the default branch was not isolated (20). 1,504 open issues on a repository with 28,320 stars and pull request numbers above 26,500, with a written issue policy and triage automation (13). Semantic versioning rules are documented and the changelog carries Breaking Changes sections (15). MLflow is at 3.17.0 and `mlflow-tracing` is classified Production/Stable, but the MCP server is marked experimental (8).)
- Payments & pricing, MLflow Tracing +50: BotGauge 10 (No x402 or other machine payment (0). Paid plans for the agent product have no published prices, and botgauge.com/pricing prices the separate QA service (0). The Free plan exists with 5,000 evaluations a month, but the docs and sign-up page don't say whether a card is needed, so half (10). A person signs up in a browser at cloud.botgauge.com and creates keys in the console (0). 0+0+10+0 = 10.); MLflow Tracing 60 (No x402, MPP or L402 (0). MLflow is free software with nothing to buy from the project, so the self-hosted rule applies (20 + 20 + 20). `pip install mlflow` and `mlflow server` need no account. Managed MLflow from Databricks, Amazon SageMaker, Azure ML and Nebius, which the README links, are separate services and are not scored here. That is a judgement call.)
- Schema & documentation, MLflow Tracing +25: BotGauge 53 (No OpenAPI file for the eval or red-team endpoints was found in the docs or llms-full.txt. Ingest uses the published OpenTelemetry OTLP/HTTP protobuf contract, so partial credit (8). llms.txt, llms-full.txt and Markdown for every page on Mintlify (10). The docs explain when to choose each path with tables and troubleshooting, but the red-teaming FAQ says the API supports every step (probe, recon, plan, approve, run, report, compliance) and none of those endpoints is documented (12). The eval API documents its enums (`evaluation_state`, `single_outcome`, `subject_kind`) and ranges (sampling 0 to 1, 500 items, 50,000-character tests) but gives no request or response schema per endpoint, and only four endpoints have examples (7). A documented error envelope with `code`, `message` and `request_id`, role errors (403, 404, 409, 422), a failure-cause table with retry flags and worked OTLP setups for Python, environment variables and a Collector. No list of error codes (11). `/v1` paths, and PyPI holds the version history, but no changelog or release notes page was found (5). 8+10+12+7+11+5 = 53.); MLflow Tracing 78 (The MCP tools are generated from the Click commands of the MLflow CLI, so every tool has a JSON Schema input with types, required fields and enums for choice options. No OpenAPI file was found in the repository, and the REST API is documented as a reference page generated from protobuf (22). llms.txt at mlflow.org/docs/latest/llms.txt links 349 Markdown pages (10). Tool descriptions are the CLI help text. They state the purpose and carry examples in command-line syntax, and they do not say when not to use a tool. `trace_id` has no description. The docs page lists 10 tools under names such as `log_feedback`, while the source registers 26 by default, with `log_trace_feedback` (12). Lists travel as comma-separated strings and feedback values as strings (9). Many examples, and few documented error responses (10). Versioned releases with a public changelog (15).)
- Maintenance & community, MLflow Tracing +21: BotGauge 67 (botgauge, botgauge-tracing and botgauge-cli 0.1.3 on 2026-10-31 (30). Four releases of each since 20 October 2026, 0.1.0, 0.1.1, 0.1.2 and 0.1.3 (20). Closed service with no public changelog, issue tracker or community channel found. Support by email at support@botgauge.com (4). One official SDK, Python, current (10). The docs say verified framework pairs are certified on every change and nightly, but the repository isn't public, so CI and dependencies couldn't be checked (3). 30+20+4+10+3 = 67. The product is 12 days old by its first package release.); MLflow Tracing 88 (MLflow 3.17.0 was tagged on 6 October 2026 (30). Seven tagged releases since 31 July, 3.15.0, 3.15.1, 3.15.2, 3.16.0, 3.16.1, 2.11.5 and 3.17.0 (20). A written issue policy, triage and stale-issue automation, and a community Slack. 1,504 issues are open and reply times were not read (14). Current official SDKs, Python at 3.17.0 and TypeScript `@mlflow/core` 0.4.0 tagged on 27 August. Presence in the official MCP registry was not checked (15). Dependabot, a lock file and cross-version test workflows. The test workflow showed 5 failed runs among 28 recent ones (9).)
- Agent ergonomics, MLflow Tracing +17: BotGauge 55 (API responses can be narrowed by `subject_ids` and `subject_kind`, a results query takes up to 500 items, and judges read at most 20,000 characters, but no field selection or summaries are documented (12). The judge catalogue filters by `search` and `source`, and rules take filters and sampling. No pagination is documented on any list endpoint (10). Errors carry a code, a message and a request id. Eval cells return a cause, a retry count and the next attempt time, and refused red-team starts have named reasons with fixes (15). `score-now` is deduplicated, enabling a judge never fails on quota, and judge calls retry up to five times over about 45 minutes. No idempotency keys on other writes (8). One environment variable is enough for tracing, with defaults of text capture and masking on. Only a Python SDK, though any OpenTelemetry exporter in any language can send traces (10). 12+10+15+8+10 = 55.); MLflow Tracing 72 (The MCP server registers 26 tools by default (traces 11, scorers 2, experiments 7, runs 6) and 45 with `MLFLOW_MCP_TOOLS=all`, counted from the source at 3.17.0. Categories can be loaded singly, so `traces` alone is 11 (15, plus 6). `search_traces` takes `filter_string`, `order_by`, `max_results`, `page_token` and `extract_fields`, and can leave spans out (20). Invalid field paths return an error that can list the valid fields. Other errors are MLflow exception text and are not documented per tool (12). No `readOnlyHint` or `destructiveHint` on any tool and no idempotency keys. `delete_traces` accepts `max_traces` as a cap (4). Few required parameters, the experiment read from `MLFLOW_EXPERIMENT_ID`, and SDKs in Python and TypeScript (15).)
- Security & auth, BotGauge +16: BotGauge 56 (Project API keys reach one project, are shown once, stored in a form that can't be read back per the DPA, show their last-used time and revoke immediately, with documented rotation steps. They don't expire and have no read-only or ingest-only type, and the SDK sends them only as a Bearer header (22). Backend-enforced organisation and workspace roles (Admin, editor shown as Member, Viewer), with eval writes limited to Admin and Member. Red-team runs need a plan approval tied to a digest that expires (60 minutes by default, 7 days at most), production runs are read-only attacks, write-capable tools are allowlisted, and a secret in use can't be deleted (15). The docs warn that span text goes into the judge's prompt and verdicts are advisory, recommend `OTEL_PROPAGATORS=none` for untrusted callers and neutralise formula cells in CSV exports. No guidance for agents reading traces or transcripts back (8). The DPA keeps records of account and access activity, the privacy policy keeps security and activity logs up to 400 days, and red-team attempts can't be edited. No customer-facing audit log is documented (5). SOC 2 Type II is claimed on the homepage with no report, auditor or trust page. No security.txt, disclosure policy or bug bounty found. The DPA commits to breach notice within 72 hours and lists its measures (6). 22+15+8+5+6 = 56.); MLflow Tracing 40 (The tracking server has no authentication by default. The `basic-auth` app adds usernames and passwords with role-based access control, ships no default admin password and requires 12 characters. Clients, the MCP server included, read a username and password or a token from environment variables. No scoped API keys were found (15). Roles can grant READ only, and 3.17.0 added grants on traces and explicit DENY. The MCP server has no read-only mode and no confirmation before `delete_traces` or `delete_experiment` (12). Traces hold whatever the application logged. No guidance on untrusted content was found in the MCP docs (2). No audit log found (0). SECURITY.md takes reports through GitHub private reporting and advisories are published with patched versions. The project stopped accepting bounty-platform reports, and no security.txt or certification was found (11).)
