Managed databases
One question, 15 recorded answers across 2 tools. Each run used a separate session. The table counts vendor mentions. 4 of 8 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 8 of the 8 providers in this category. 1 cleared every barrier we test. These HTTP checks do not establish integration success. Feature fit, price and support are outside their scope.

The question we asked
We are moving off a Postgres instance somebody set up on a virtual machine three years ago and nobody wants to be the one patching it. I want a managed database with backups, a sane connection story for serverless, and branching for our preview environments if possible. Which provider would you use, and what else did you consider?
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
