Also [GrowthBook](https://www.anchorterminal.com/tools/growthbook.md), BB, 70.1/100.\n- Reliability: [GrowthBook](https://www.anchorterminal.com/tools/growthbook.md), 86/100 on reliability, against 79 for the overall leader.\n- Schema \u0026 documentation: [LaunchDarkly](https://www.anchorterminal.com/tools/launchdarkly.md), 89/100 on schema \u0026 documentation, against 82 for the overall leader.\n- Agent ergonomics: [PostHog](https://www.anchorterminal.com/tools/posthog.md), 78/100 on agent ergonomics, against 71 for the overall leader.\n- Security \u0026 auth: [PostHog](https://www.anchorterminal.com/tools/posthog.md), 84/100 on security \u0026 auth, against 74 for the overall leader.\n- Maintenance \u0026 community: [GrowthBook](https://www.anchorterminal.com/tools/growthbook.md), 89/100 on maintenance \u0026 community, against 81 for the overall leader.\n- Transparency \u0026 trust: [Mixpanel](https://www.anchorterminal.com/tools/mixpanel.md), 84/100 on transparency \u0026 trust, against 75 for the overall leader.\n- Self-hosting under an open licence: [GrowthBook](https://www.anchorterminal.com/tools/growthbook.md), self-hosted, MIT for the core and for the MCP server licence. Also [Matomo](https://www.anchorterminal.com/tools/matomo.md), self-hosted, Matomo core is GPL-3 licence.\n\n## How to choose\n\n- Answers against known values: Ask a funnel and a retention question whose answer you already know, since a query that returns a plausible number can still count events wrongly.\n- Query limits and result size: Check the limits on query rate, result size and time range, since an agent that loops over a large cohort can hit them partway through an analysis.\n- Raw event export and retention: Check whether raw events can be exported and how long they are kept, since an agent cannot re-run a question once the events have aged out.\n- Experiment results over the API: Check whether experiment results and flag states can be read through the API, since an agent deciding a rollout needs the same numbers the dashboard shows.\n\n- How the benchmark tests this category: One fixed event set loaded into each listing, then the same questions asked through its API or MCP server (a funnel conversion, a retention curve, a cohort size and an experiment result). We check the answers against known values and the limits on queries. In this run listings are graded from public evidence against the published checklist.\n\n## Each one in detail\n\n### 1.

GrowthBook is second with 70.1 (BB).\n\n### How many product analytics and experimentation tools are agent-ready?\n\n2 of the 13 ranked here grade BB or better, the bar for agent-ready on the Anchor benchmark.\n\n### Which product analytics and experimentation tools accept x402 payments?\n\nNone of the ranked listings here accepts x402 for its main call yet.\n\n### How is this list ranked?\n\nBy the Anchor benchmark score out of 100, a weighted mean of the scored categories minus deductions for negative events, from public evidence re-checked as vendors change. Listings cannot pay for a place. The latest assessment behind this page is from 9 October 2026.\n\n## How this list is made\n\nThe order is the Anchor benchmark score, the same number as on each listing. Each listing is graded from public evidence against the benchmark checklist, and the picks are worked out from those grades, prices and facts. No listing pays for its place, and paid audits or listing help never change a score.\n",
