Cursor shrinking is the unused half of the JetBrains 2026 survey. Work usage among professional developers went from 18 percent in January to 12 percent in May to July, while awareness climbed from 69 to 75. Heise led with Claude Code as the most popular coding agent. The chair that emptied was the IDE that defined the category.
Copilot fell on the same chart. Claude Code and Codex rose. Those two are documented as terminal-first products. OpenCode showed up with 7 percent work usage and 42 percent mindshare and a curl installer.
You'll keep buying Cursor seats if the meeting still ranks tools by who is in the timeline. The timeline is awareness. The seat is work usage. The surface that grew is a CLI.
How JetBrains counted a shrinking seat
Two waves, one slope. The seat is work usage, not the poster.
Can you trust a JetBrains survey to say Cursor is shrinking? Only if you read the two waves they stacked, and the weighting they put on them.
The May to July numbers come from the Developer Ecosystem Survey 2026, tenth edition, Strategic Research and Market Intelligence. Heise printed N=15,509 on that wave. Professional developers means people who code in a listed job role, and about 90 percent of the sample is Developer, Programmer, or Software Engineer.
Eight languages. Regional quotas. Then a reweight. The 2025 methodology is still the honesty document they point at.
- Region, so China does not silently become the globe
- Employment status
- Programming language
- Familiarity with JetBrains products, which is the awkward dial when the shrinking tool is a VS Code fork
January is a different instrument, the AI Pulse of more than 10,000, promoted without mentioning AI so the sample would not fill with fans. Cursor and Claude Code were tied at 18 percent work usage in that wave. Copilot was 29 percent. Codex was 3 percent.
The May to July work-usage bars sum to 110 percent. That is multi-select, not a single chair. Someone can tick Cursor and Claude Code on the same form. Self-report. Not seat telemetry. Not git trailers. JetBrains users may have been more willing to finish, which is a fun bias when the shrinking product is a VS Code fork.
This part is boring on purpose. The drama is the slope.
The editor-native seats fell together
Work usage, Jan 2026 versus May to Jul 2026
| Category | Cursor (% of professional developers) | GitHub Copilot (% of professional developers) | Claude Code (% of professional developers) | Codex (% of professional developers) |
|---|---|---|---|---|
| Jan 2026 | 18 | 29 | 18 | 3 |
| May-Jul 2026 | 12 | 21 | 39 | 16 |
Cursor and Copilot slid. Claude Code and Codex climbed. Editor-native seats lost the work.
Is this a Cursor flop, or a surface class losing? Look at the pair.
Cursor went from 18 percent work usage in the January Pulse to 12 percent in May to July. JetBrains called it a small decline. A third of the reported Cursor seats left in half a year. Small is a polite word for a product that used to be the demo.
GitHub Copilot, the other editor-native seat, went from 29 percent in that January Pulse to 21 percent in May to July. The August write-up says 29 percent a year ago. Heise pinned the 29 to January. Either way the arrow is down, and it is not a Cursor-only story.
Awareness for Cursor still rose, 69 percent in January to 75 percent in May to July. Copilot kept 79 percent mindshare. Heise printed the same 79 percent for Claude Code. Fame is cheap. Work usage is the bill.
The conversion story, 39 percent work usage and 31 percent most-used, already lives in Claude Code is the default coding agent at work. That post is who won the chair. This one is which kind of chair lost.
Tab autocomplete still lives in editors. Nobody is arguing the file tree died. The thing that shrank is the product that tried to make the editor the agent.
The CLI-shaped seats took the work
The prompt ate the tab key. Claude Code and Codex rode that path.
What rose while Cursor fell? The tools whose first surface is a prompt, not a tab key. That is an association in two survey waves, not a tagged migration of named people.
Claude Code's docs call it an agentic coding tool available in your terminal, IDE, desktop app, and browser. The first tab is the full-featured CLI. You cd into a repo and type claude. That is a different object than a fork of VS Code with Composer bolted to the side pane.
Work usage went from 18 percent in January to 39 percent in May to July. Same window as the Cursor drop. Do not turn that into a conversion sermon. The neighbor already did the 31 percent most-used math.
Codex CLI is OpenAI's coding agent that you run locally from your terminal. Inspect, edit, run, automate. Work usage went from 3 percent to 16 percent, about 5x, the steepest climb on the chart. Awareness jumped from 27 percent to 65 percent. The openai/codex repo is public and still getting pushes.
OpenCode is the leak in a market that otherwise looks like a vendor race. 7 percent work usage. 42 percent mindshare. No big company name. The README leads with a curl installer and a terminal UI screenshot. Desktop is labeled beta. A same-task bench already lived here. OpenCode vs Claude Code on four graded tasks both hit 4/4. Paths diverged. Share is this survey. Pass rate is that post.
The most conspicuous growth sits on products you start with a binary in a shell. Multi-select means those ticks can sit next to a leftover Cursor tick. The pattern is still a surface shift.
The IDE is becoming a host
The editor is the dock. The agents are the boats.
If the terminal is winning, why are IDEs stuffing agents into chat panels? Because the editor is not dying. It is becoming a dock.
JetBrains wrote the concession into the same post as the survey. Claude Agent, Codex, GitHub Copilot, and OpenCode are integrated directly into the AI chat of JetBrains IDEs, and dozens of other agents, including Cursor, can be added via the Agent Client Protocol.
The JetBrains plugin for Claude Code is even blunter. It runs the claude command in the IDE's integrated terminal and connects to it. It does not bundle its own copy of the CLI. Install both pieces, or the plugin shows Cannot launch Claude Code.
Cursor shipped a CLI of its own in January 2026. The help article says it works with any IDE or editor, not just Cursor. Vendor docs, so no link. The sentence is the tell. The company that made the editor-as-agent is now selling the agent as a thing you run in someone else's editor.
The survey names the product, not the surface, so it cannot prove a brand-internal CLI migration did not happen. It also cannot hide a falling product number. The Cursor line is still the one shrinking.
Hosting is not winning. A marina is not a boat. Paying for Cursor because you want a coding agent is paying rent on the building to hire the tenant.
Keep VS Code. Keep JetBrains. Keep Neovim. Put the agent in a pane. That is the stack the slope is describing, even when the IDE vendor is the one drawing the picture.
China and the Claude tab inside Cursor
China is the ugly column. The guest tab is Cursor acting as a host.
Where is the drop ugliest? China, and then the people running a guest CLI inside the IDE that was supposed to be the product.
JetBrains printed the China split in the same breath as the global decline, which is the honest way to do it. Cursor work usage there went from 28 percent in January to 16 percent in May to July. No fetched primary says why. Great Firewall stories and local-IDE rumors stay in the kill pile until someone publishes a table.
The global 18 to 12 is not only China. A 12-point regional crash can drag a global average. It cannot invent the Copilot drop, and it cannot invent Claude Code's 18 to 39. Treat China as the ugly column, not the whole explanation.
Then there is the guest tab. On 10 August 2026 a Cursor forum thread opened because 3.15.5 reserved the secondary sidebar for Cursor Agent. Users who had been docking Claude Code there called it a massive regression. One shop said they would move back to Visual Studio Code if the tab did not return.
That is Cursor acting as a host. A guest tab is not share for the editor-as-agent. It is the terminal eating the IDE from the inside of the IDE.
HN already had the hybrid in plain clothes. On Ask HN, IDE or CLI, one person started in Cursor because tab completion was superb, then switched to Claude Code entirely, with six paid months left on the Cursor sub. On Windows they still opened VS Code for the file browser. They did not use any of the IDE parts of the IDE. On Linux the whole loop was terminals. That is a person who already owned the editor, then stopped paying for the agent that came glued to it.
Another comment, under the SpaceX thread, was shorter. A systems engineer stopped using Cursor after getting comfortable with Codex and Claude. Normal editor. A todo. Then Codex. That is texture, not a census. It matches the slope.
What a work-usage slope cannot say
What would make the shrinking claim fold? A different question, a sample that does not lean JetBrains, or a product name that hid a CLI.
Self-report inflates the cool tool and hides the unfashionable one. Weighting for JetBrains familiarity is meant to shrink that. A VS Code fork can still be undercounted if JetBrains users finished more of the form. Lingering bias is named in the 2025 write-up. Raw 2026 microdata is not out.
The survey names Cursor, not Cursor IDE versus Cursor CLI. The CLI shipped in January, inside the window. That split is missing, so a Cursor CLI migration can hide inside the same brand name. The published number is still the product, and the product fell.
ChatGPT is missing from the May to July subset. The January Pulse still had the ChatGPT chatbot at 28 percent for coding tasks at work. This post cannot rank Claude Code over ChatGPT on a 2026 number JetBrains did not print. Stay inside the cut.
12 percent still use Cursor at work. 21 percent still use Copilot. Enterprise policy can still be Copilot-only, or Cursor-on-the-laptop, while the public survey looks like a CLI town. Code review is the bottleneck either way. Adoption is not the merge queue.
No telemetry. No seat count. No invoice dump. Stack Overflow's 2025 AI survey is year-ago texture, agents not yet mainstream, ChatGPT and Copilot as the out-of-the-box names. Then the first half of 2026 happened and the JetBrains chart bent. A slope in self-report is a weather report. It is still the best published weather on this question.
Keep the editor, move the agent
Do you still buy Cursor seats this quarter? Reassess the renewal if the thing you wanted was the agent and a CLI already does that work. Keep the seats if tab completion, the GUI diff, or a policy box is the actual job.
Keep the editor you already trust. Put the agent in a CLI you can run in a pane, in CI, on a phone, in a worktree. Claude Code and Codex are the ones the survey says people moved to. OpenCode is the side door if you want an open harness.
- VS Code, JetBrains, Neovim, Zed, whatever actually opens the tree
- Claude Code or Codex in a pane, not as the reason you pay for a fork
- Copilot or Cursor Tab only if autocomplete is still a daily habit
- A second agent ready, because Codex was at 3 percent in January
You'll ship a Cursor SKU and still watch the people who can choose live in a terminal. That is not hypocrisy. That is two clocks. Procurement is annual. Surface change is weekly.
If tab completion is still the daily habit, keep Copilot or Cursor Tab as autocomplete. Do not confuse that seat with the agent default. They are not the same product, and the slope is about the second one.
JetBrains called the Cursor drop small. The category that invented the AI IDE just watched work usage fall while the name got more famous. Rank the agent by the slope, not the poster. The editor stays. The agent moves.
