# Do coding agents recommend Upstash? > Upstash was chosen in 4% of 215 judged cloud sessions, ranking fifth. Measured with Claude Code, Codex and Cursor. Source: https://armature.tech/library/do-coding-agents-recommend-upstash Published: 2026-09-03 Publisher: Armature, Inc. (https://armature.tech) --- > Upstash was chosen in 4% of 215 judged cloud sessions, ranking fifth. It was also raised as a candidate in 27 further sessions without being chosen. This page reports what happened when Claude Code, Codex and Cursor had to solve a problem in cloud inside a realistic codebase. Not what a chat assistant says about Upstash. 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 cloud in general, and the splits below cannot separate the two. Treat them as a description of that repository. ## The numbers | | | | --- | --- | | Category | Cloud | | Sessions in the category | 215 | | Sessions where Upstash was chosen | 8 | | Install share | 4% | | Rank in category | 5 of 8 | | Codebases it won in | 1 | | Raised as a candidate, not chosen | 27 | | Chosen when considered | 23% | | Site | upstash.com | ## By agent With 8 wins spread across three 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 Upstash | Share | | --- | --- | --- | --- | | Claude Code | 72 | 5 | 7% | | Codex | 72 | 3 | 4% | | Cursor | 71 | 0 | 0% | ## By who was asking Upstash performs similarly across the four kinds of buyer, from 0% to 6%. That is unusual: the category leader changed with the persona in 14 of the 18 categories we measured. | Who is asking | Sessions | Chose Upstash | Share | | --- | --- | --- | --- | | Senior engineer | 143 | 8 | 6% | | Enterprise team | 72 | 0 | 0% | ## What Upstash was up against The full ranking in cloud, from the same sessions: | # | Product | Runs won | Share | | --- | --- | --- | --- | | 1 | AWS | 133 | 62% | | 2 | Google Cloud | 36 | 17% | | 3 | Cloudflare | 17 | 8% | | 4 | Inngest | 8 | 4% | | 5 | Upstash **(this page)** | 8 | 4% | | 6 | Vercel Queues | 3 | 1% | | 7 | Cloudflare + Upstash | 2 | 1% | | 8 | Render | 1 | 0% | ## What this means This is an integration problem, not a presence problem. Agents raised Upstash in 27 sessions and chose it in 8, so it reaches the shortlist and then loses. Something at the last step is costing the session, and in our data that is usually a quickstart that does not run when pasted, documentation describing an interface that changed, or a package name that does not match the product name. That is the cheaper of the two problems to have. The reason is written down in each losing transcript. ## Where these numbers come from The 215 sessions in cloud 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 cloud run can be replayed on [the board](/leaderboards/cloud). If you work on Upstash: 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 Upstash? Yes. Upstash was chosen in 8 of the 215 judged sessions in cloud, a 4% install share, ranking fifth in its category. ### Does Claude Code recommend Upstash? In 5 of the 72 sessions in cloud run with Claude Code, which is 7%. ### Do different coding agents treat Upstash differently? Not much. The three agents chose it at similar rates, between 0% and 7% of their runs. ### 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 Upstash considered but not chosen? It was raised as a candidate in 27 sessions without being chosen, and chosen in 8. That is a 23% conversion from considered to chosen. ## Read next - [How to get picked for cloud by coding agents](https://armature.tech/library/cloud-coding-agents-playbook) (Markdown: https://armature.tech/library/cloud-coding-agents-playbook.md) - [Do coding agents recommend AWS?](https://armature.tech/library/do-coding-agents-recommend-aws) (Markdown: https://armature.tech/library/do-coding-agents-recommend-aws.md) - [Do coding agents recommend Google Cloud?](https://armature.tech/library/do-coding-agents-recommend-google-cloud) (Markdown: https://armature.tech/library/do-coding-agents-recommend-google-cloud.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.
