the terminal agent just beat the in-ide assistant. jetbrains' 2026 ecosystem survey of 15,000+ developers has claude code at 39% workplace adoption, nearly double copilot's 21%, which slid from 29% in a year.
the agent moved out of the editor and took the market with it.
Context
JetBrains' post of 18 August 2026 on its Developer Ecosystem Survey 2026, of more than 15,000 professional developers, weighted and quota-sampled, fielded May to July 2026, reports Claude Code at about 39% workplace adoption, up from 18% in January and 47% in the US, Codex at 16%, Copilot at 21% against 29% a year ago, and Cursor at 12%. It reports 90% use agents weekly and 68% daily.
All figures match the post. JetBrains sells AI coding tools itself, so it is the survey author and not independent of its own product, and the sample is JetBrains-surveyed developers despite weighting. The 29% a year ago is an earlier survey wave from the May to July figure; the comparison is the post's own. This is survey adoption, not a benchmark, so it says nothing about which tool is better.

the current is now being asked to draw its own map: china’s langya 2.0 predicts six ocean phenomena including internal waves and mesoscale eddies, a deep net called wenhai resolves eddies globally with air sea flux formulas built in, and scripps infers surface currents from the way temperature patterns deform in satellite images. the ocean now files its own circulation report.
