How much revenue are database companies losing because agents aren’t able to sign up autonomously? Today, we’re releasing @tryscope_app's first database benchmark. We tested 18 hosted databases to see which are ready to win that market. We measured which databases agents could use, analyzed where they failed, and identified best practices to fix the blockers. Across 1,035 sessions, only 16.6% reached a first working result and failed sessions all came from products not being agent friendly. We tested 20 model-and-agent-tool combinations across harnesses including Claude Code, Codex and Cursor. The task: start with no account, set up the named database, write a record, and hand over the credentials. An account or API key alone didn’t count. What we found: → @prisma led with an 88.3% success score, followed by @upstash at 63.3%, @neondatabase and @niledatabase at 43.3%, and @ClickHouseDB at 38.3%. → 7 of 18 products had zero successful sessions across every agent tested. → CAPTCHAs stopped 373 sessions. Bot blocks stopped another 105. Other barriers included rejected agent email domains and OAuth-only flows. → 50 of the 172 successful sessions used a working database without creating an account. Letting agents try the product before signing up made a difference. An agent can arrive knowing exactly which product it wants to use and still never become a user. For developer tools, the path from “use this database” to a working result is part of your conversion funnel.
