# Do coding agents recommend Cursor SDK? > Cursor SDK was chosen in 14% of 681 judged agent frameworks sessions, ranking second. Measured with Claude Code, Codex and Cursor. Source: https://armature.tech/library/do-coding-agents-recommend-cursor-sdk Published: 2026-09-03 Publisher: Armature, Inc. (https://armature.tech) --- > Cursor SDK was chosen in 14% of 681 judged agent frameworks sessions, ranking second. It was also raised as a candidate in 98 further sessions without being chosen. This page reports what happened when Claude Code, Codex and Cursor had to solve a problem in agent frameworks inside a realistic codebase. Not what a chat assistant says about Cursor SDK. What an agent actually installed. ## The numbers | | | | --- | --- | | Category | Agent frameworks | | Sessions in the category | 681 | | Sessions where Cursor SDK was chosen | 94 | | Install share | 14% | | Rank in category | 2 of 35 | | Codebases it won in | 12 | | Raised as a candidate, not chosen | 98 | | Chosen when considered | 49% | | Site | cursor.com | ## By agent The three agents treat Cursor SDK very differently. Cursor chose it in 47% of its sessions in this category and Claude Code in 0%, a spread of 47 points. | Agent | Sessions | Chose Cursor SDK | Share | | --- | --- | --- | --- | | Claude Code | 237 | 0 | 0% | | Codex | 243 | 0 | 0% | | Cursor | 201 | 94 | 47% | A single blended install share would report the midpoint and hide both ends. If most of your users run Claude Code, your real position here is 0%, not 14%. ## By who was asking Cursor SDK performs similarly across the four kinds of buyer, from 9% to 20%. That is unusual: the category leader changed with the persona in 14 of the 18 categories we measured. | Who is asking | Sessions | Chose Cursor SDK | Share | | --- | --- | --- | --- | | Vibe coder | 163 | 28 | 17% | | Junior developer | 157 | 21 | 13% | | Senior engineer | 254 | 24 | 9% | | Enterprise team | 107 | 21 | 20% | ## What Cursor SDK was up against The full ranking in agent frameworks, from the same sessions: | # | Product | Runs won | Share | | --- | --- | --- | --- | | 1 | Built in-house (no product adopted) | 170 | 25% | | 2 | Vercel AI SDK | 95 | 14% | | 3 | Cursor SDK **(this page)** | 94 | 14% | | 4 | Inngest | 50 | 7% | | 5 | Temporal | 29 | 4% | | 6 | Prism | 28 | 4% | | 7 | OpenAI Agents SDK | 24 | 4% | | 8 | LangGraph | 23 | 3% | ## What this means Cursor SDK was raised in 98 sessions and chosen in 94. 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 681 sessions in agent frameworks are part of a published set of 5,292, 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 agent frameworks run can be replayed on [the board](/leaderboards/agent-frameworks). If you work on Cursor SDK: 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 Cursor SDK? Yes. Cursor SDK was chosen in 94 of the 681 judged sessions in agent frameworks, a 14% install share, ranking second in its category. ### Does Claude Code recommend Cursor SDK? In 0 of the 237 sessions in agent frameworks run with Claude Code, which is 0%. ### Do different coding agents treat Cursor SDK differently? Yes, and by a wide margin. Cursor chose it in 47% of its runs and Claude Code in 0%. ### How was this measured? Real coding agents at pinned versions were run in sandboxes inside 51 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 Cursor SDK considered but not chosen? It was raised as a candidate in 98 sessions without being chosen, and chosen in 94. That is a 49% conversion from considered to chosen. ## Read next - [How to get picked for agent frameworks by coding agents](https://armature.tech/library/agent-frameworks-coding-agents-playbook) (Markdown: https://armature.tech/library/agent-frameworks-coding-agents-playbook.md) - [Do coding agents recommend Vercel AI SDK?](https://armature.tech/library/do-coding-agents-recommend-vercel-ai-sdk) (Markdown: https://armature.tech/library/do-coding-agents-recommend-vercel-ai-sdk.md) - [Do coding agents recommend Inngest?](https://armature.tech/library/do-coding-agents-recommend-inngest) (Markdown: https://armature.tech/library/do-coding-agents-recommend-inngest.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.
