Summary

A survey of nearly 1,000 software engineers reveals that AI tools are now mainstream, with 95% of respondents using them weekly and 75% using AI for at least half their work. Claude Code, released in May 2025, has rapidly become the most-used AI coding tool, surpassing GitHub Copilot and Cursor. Anthropic's Opus and Sonnet models dominate coding tasks. Most engineers (70%) juggle two to four AI tools simultaneously. AI agent usage is also rising, with 55% of respondents regularly employing them for tasks like code review and debugging; Staff+ engineers lead this adoption at 63.5%. Company size significantly influences tool choice, with smaller companies (75%) favoring Claude Code and larger enterprises (56%) defaulting to GitHub Copilot, likely due to procurement preferences. Claude Code is also the most loved tool, cited by 46% of users, especially senior leaders.

Key takeaway

For AI Engineers evaluating coding tools, recognize Claude Code's rapid ascent as the market leader and its high user satisfaction, especially among senior leadership. If your organization is a smaller entity, Claude Code is likely to be a strong fit, while larger enterprises may find GitHub Copilot more prevalent due to existing procurement channels. Explore AI agents for tasks like code review and debugging, as their adoption correlates with increased positive sentiment towards AI.
