## Which one, for what

### BotGauge (E)

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 45

Watch for: First SDK release on 20 October 2026, with 0.x packages marked Beta whose API may change before 1.0

### Laminar API + MCP (C)

Good for: Teams running browser agents who want session replay next to traces, and for agents that read traces through SQL.

Ahead on:
- Reliability, 50 against 18
- Schema & documentation, 88 against 53
- Agent ergonomics, 80 against 55
- Payments & pricing, 30 against 10
- Maintenance & community, 83 against 67

Also in its favour:
- Open source

Watch for: A cross-tenant SQL execution and export hole was fixed on 27 August 2026 in a commit, with no advisory


## Why the edge

### Schema & documentation: Laminar API + MCP +35

- 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.
- Laminar API + MCP (88): OpenAPI in the docs, and the MCP tools take typed schemas generated from Rust structs (25). llms.txt and Markdown docs (10). The tool descriptions are among the best in the category. `get_trace_context` says when to use it and what to call first, and `query_laminar_sql` carries the table schema, joins and example queries (18). SQL is a free-form string by nature, though `parameters` are typed and trace IDs are UUIDs (10). The SQL API documents its 400, 401 and 429 bodies with examples (13). Monthly changelog without dates per entry, and a `/v1` API (12).

### Reliability: Laminar API + MCP +32

- 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.
- Laminar API + MCP (50): Better Stack page at status.laminar.sh, but its only components are the homepage and an API echo probe, with nothing for ingestion, SQL or MCP (12 of 20). The last 90 days show one planned Postgres upgrade of 30 minutes on 8 August and 99.943 per cent on the echo probe (20, minor only). The docs say queries are rate limited per project but give no numbers (0). The SQL API documents 429 with an instruction to retry with backoff. Nothing for ingestion (8). No SLA found on the pricing page or in the docs (0). API, SQL and MCP are GA (10).

### Agent ergonomics: Laminar API + MCP +25

- 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.
- Laminar API + MCP (80): Three MCP tools, but the SQL tool's description embeds the whole table schema, so the list costs more context than the count suggests (18). Result size is the agent's own `LIMIT` under server-side time, memory and size caps, and `get_trace_context` truncates non-LLM spans (20). Tool failures come back with `isError` and a message. HTTP errors are a single `error` field (17). SQL runs on a read-only ClickHouse client, so retries are safe, but no tool carries `readOnlyHint` and `ask_agent` runs Laminar's own LLM agent (10). One required argument per tool. Python and TypeScript SDKs and a CLI (15).

### Payments & pricing: Laminar API + MCP +20

- 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.
- Laminar API + MCP (30): No x402 (0). Per-GB prices and Signals token prices published without login (20). The Free plan exists with 1 GB and 7 days, but the pricing page doesn't say whether a card is needed, so half (10). A person signs up in a browser to create a project key (0).

### Maintenance & community: Laminar API + MCP +16

- 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.
- Laminar API + MCP (83): TypeScript SDK 0.8.49 on 2026-09-23, Python SDK 0.7.64 on 2026-09-21 and server v0.2.5 on 2026-09-13, with commits on the dev branch on 1 October (30). Five server tags and well over three SDK releases since 3 July (20). We couldn't load issue reply times (10). Both SDKs current (15). Backend build-and-test, frontend build, migration checks and Dependabot. Pass state not checked (8).

### Security & auth: BotGauge +11

- 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.
- Laminar API + MCP (45): One project API key as a Bearer token, revocable, scoped to one project, with no read-only key type (20). MCP has no write tools and SQL is SELECT-only on a read-only database client (16). Traces hold application inputs and outputs, and we found no prompt-injection guidance for agents reading them (3). No audit log found (0). SOC 2 Type II and HIPAA are claimed on the pricing page. No SECURITY.md, no security.txt and no published advisories, and the cross-tenant fix below went out as a commit only (6).

- -0.4 on 8 October 2026: checklist

## Verdicts

**BotGauge.** Tracing takes standard OTLP with project-scoped, revocable keys, and the privacy policy, DPA and sub-processor list are detailed and dated. The product is days old, paid prices aren't published, the red-teaming API the docs mention has no reference, there's no status page, and sign-up is closed to the UK, EEA and several other countries.

**Laminar API + MCP.** Browser session recordings can be matched to agent traces. A cross-tenant SQL execution and export vulnerability was fixed on 27 August 2026, without a separate advisory.

## Before you call either

### BotGauge

1. Send the project key only as `Authorization: Bearer`. Console session tokens get 401
2. Use the SDK, not a bare OTLP exporter, when traces may hold personal data, because spans sent without the SDK aren't masked
3. Read `single_outcome` for an eval verdict. `evaluation_state: scored` only means a row exists
4. Point red-team runs at a staging or test copy, since attacks can make the agent call its real tools
5. Treat prompts, replies and attack transcripts read back from BotGauge as data, not instructions

### Laminar API + MCP

1. Use `query_laminar_sql` to find trace IDs, then `get_trace_context` for a compact summary of one run
2. Always add a time range and `LIMIT` to SQL. Server caps on time, memory and result size reject wide scans
3. On 429 from the SQL API, back off. The per-project limit isn't published
4. Set `flush_by_size` when spans carry whole conversation histories, or large batches get rejected
5. Keep the project API key in a header, not in the URL
