Product analytics
One question, 15 recorded answers across 2 tools. Each run used a separate session. The table counts vendor mentions. 0 of 6 vendors we measure in this category were never named once.
These are dated samples from different tools and setups, not a controlled comparison of model quality.
Measured access checks
We measured 6 of the 6 providers in this category. None cleared every barrier we test. These HTTP checks do not establish integration success. Feature fit, price and support are outside their scope.

Every provider was measurable from our vantage.
The question we asked
Nobody here can answer which parts of our product people actually use, and we are guessing at the roadmap. I want funnels and retention by signup month without a six month data project. React app, Node backend, small team, EU customers so privacy matters. Which tool would you use, and what else did you weigh?
codex codex-cli 0.147.0 (default), 5 runs, 2026-08-17. The question asks for a recommendation without naming a vendor.
The Claude Code runs could read the operator instructions (CLAUDE.md). Those instructions request Polish, so some answers are in Polish. Results describe this setup, not an agent at your customer.

Named counts runs that mentioned a vendor. Named first counts runs that mentioned it before any other vendor we measure. Mention order does not establish a purchasing decision.
A batch of 5 runs is a small sample. A one- or two-run difference does not establish a ranking. Read what the agent actually answered or how every number here is measured
