This post from the JetBrains Research blog reports how professional developers were using AI coding agents at work, based on JetBrains’ Developer Ecosystem Survey 2026 — described as the tenth edition of a large-scale, globally representative survey of more than 15,000 professional developers. Its headline figure is that, as of May–July 2026, 90% of professional developers were using AI coding agents at work at least weekly, local or remote, and 68% were using them daily.
Most of the post compares individual tools by adoption at work and by awareness, comparing its May–July 2026 figures with earlier ones — mostly from January 2026, and for GitHub Copilot from a year earlier. Its central finding is the rise of Claude Code to the most widely adopted AI coding tool at work, alongside rapid growth for OpenAI Codex and declines for GitHub Copilot and Cursor. The post closes by describing JetBrains’ own agent offerings and integrations.
Key Points
- As of May–July 2026, 90% of professional developers in the survey used AI coding agents at work at least weekly and 68% used them daily.
- Around 39% of professional developers worldwide used Claude Code at work, up from 18% in January 2026 (47% in the United States); the post describes it as used twice as often as GitHub Copilot, and as the most used AI coding tool for 31% of developers, which it calls an almost 80% conversion rate from regular use to single most-used tool.
- Codex adoption at work grew roughly fivefold, from 3% in January 2026 to 16%, while awareness of it rose from 27% to 65% of developers.
- GitHub Copilot’s adoption fell from 29% a year earlier to 21%, though it remained among the most widely known tools at 79% awareness.
- Cursor’s awareness rose from 69% to 75% while its adoption fell from 18% to 12%, with the largest drop reported in China (28% to 16%).
- OpenCode, an open-source coding agent, reached 7% adoption with 42% awareness, which the post highlights as notable for a tool without a large company behind it.
- Google Antigravity held steady at 6% adoption while its awareness rose from 29% to 47%, with India its strongest market at 15% adoption.
- JetBrains reports around 9% of developers using its own AI in its IDEs and/or its Junie agent at work.
Context
The figures are self-reported survey data published by a vendor of development tools, and the final part of the post promotes JetBrains’ own products — agent integrations in its IDEs via the Agent Client Protocol, the Air agentic development environment in preview, and JetBrains Central. The methodology notes state that “professional developers” covers respondents in several coding-related roles, about 90% of whom are developers, programmers or software engineers; that the survey is localized into eight languages with regional response quotas; and that results are statistically reweighted by region, employment status, programming language and familiarity with JetBrains products.
