# Do coding agents recommend MotherDuck? > MotherDuck was chosen in 2% of 445 judged databases sessions, ranking seventh. Measured with Claude Code, Codex, Cursor, Grok Build CLI and Muse Code. Source: https://armature.tech/library/do-coding-agents-recommend-motherduck Published: 2026-09-23 Publisher: Armature, Inc. (https://armature.tech) --- > MotherDuck was chosen in 2% of 445 judged databases sessions, ranking seventh. It was also raised as a candidate in 21 further sessions without being chosen. This page reports what happened when Claude Code, Codex, Cursor, Grok Build CLI and Muse Code had to solve a problem in databases inside a realistic codebase. Not what a chat assistant says about MotherDuck. What an agent actually installed. One thing to read first: every one of those wins came from a **single codebase**. That is a result about one repository rather than about databases in general, and the splits below cannot separate the two. Treat them as a description of that repository. ## The numbers | | | | --- | --- | | Category | Databases | | Sessions in the category | 445 | | Sessions where MotherDuck was chosen | 10 | | Install share | 2% | | Rank in category | 7 of 14 | | Codebases it won in | 1 | | Raised as a candidate, not chosen | 21 | | Chosen when considered | 32% | | Site | motherduck.com | ## By agent With 10 wins spread across 5 agents, the rates below are small numbers and a difference between them is not yet a finding. They are here because the direction is worth knowing, not because the gap is established. | Agent | Sessions | Chose MotherDuck | Share | | --- | --- | --- | --- | | Claude Code | 147 | 1 | 1% | | Codex | 121 | 0 | 0% | | Cursor | 142 | 8 | 6% | | Grok Build CLI | 18 | 1 | 6% | | Muse Code | 17 | 0 | 0% | ## By who was asking MotherDuck performs similarly across the four kinds of buyer, from 0% to 4%. That is unusual: the category leader changed with the persona in 23 of the 29 categories we measured. | Who is asking | Sessions | Chose MotherDuck | Share | | --- | --- | --- | --- | | Vibe coder | 74 | 0 | 0% | | Junior developer | 136 | 0 | 0% | | Senior engineer | 235 | 10 | 4% | ## What MotherDuck was up against The full ranking in databases, from the same sessions: | # | Product | Runs won | Share | | --- | --- | --- | --- | | 1 | Neon | 285 | 64% | | 2 | Azure Database for PostgreSQL Flexible Server | 40 | 9% | | 3 | Azure SQL Database | 38 | 9% | | 4 | Amazon RDS for PostgreSQL | 25 | 6% | | 5 | Supabase | 14 | 3% | | 6 | Scaleway Managed Database for PostgreSQL | 12 | 3% | | 7 | MotherDuck **(this page)** | 10 | 2% | | 8 | DigitalOcean Managed PostgreSQL | 6 | 1% | ## What this means MotherDuck was raised in 21 sessions and chosen in 10. That ratio is balanced enough that the ceiling is presence rather than integration: the product converts reasonably when it is on the table, and it is not on the table often enough. ## Where these numbers come from The 445 sessions in databases are part of a published set of 11,878, run with real coding agents inside realistic codebases and judged blind. The full method is on one page: [how we measured this](/library/how-we-measured-this). Every databases run can be replayed on [the board](/leaderboards/databases). If you work on MotherDuck: the judge recorded a reason for every session where it was raised and passed over. Those reasons are in the transcripts. ## Common questions ### Do coding agents recommend MotherDuck? Yes. MotherDuck was chosen in 10 of the 445 judged sessions in databases, a 2% install share, ranking seventh in its category. ### Does Claude Code recommend MotherDuck? In 1 of the 147 sessions in databases run with Claude Code, which is 1%. ### Do different coding agents treat MotherDuck differently? Not much. Claude Code, Codex and Cursor chose it at similar rates, between 0% and 6% of their runs. ### How was this measured? Real coding agents at pinned versions were run in sandboxes inside 91 realistic codebases and asked to solve real tasks. A simulated project owner approved or questioned each recommendation before any code was written, and a judge from a model family that builds none of the agents read every session blind. ### How often is MotherDuck considered but not chosen? It was raised as a candidate in 21 sessions without being chosen, and chosen in 10. That is a 32% conversion from considered to chosen. ## Read next - [How to get picked for databases by coding agents](https://armature.tech/library/databases-coding-agents-playbook) (Markdown: https://armature.tech/library/databases-coding-agents-playbook.md) - [Do coding agents recommend Neon?](https://armature.tech/library/do-coding-agents-recommend-neon) (Markdown: https://armature.tech/library/do-coding-agents-recommend-neon.md) - [Do coding agents recommend Azure Database for PostgreSQL Flexible Server?](https://armature.tech/library/do-coding-agents-recommend-azure-database-for-postgresql-flexible-server) (Markdown: https://armature.tech/library/do-coding-agents-recommend-azure-database-for-postgresql-flexible-server.md) - [Do Claude Code, Codex and Cursor pick the same tools?](https://armature.tech/library/do-claude-code-and-codex-agree) (Markdown: https://armature.tech/library/do-claude-code-and-codex-agree.md) --- Armature helps software products get discovered and used by coding agents.
