Stack Overflow published the results of its 2026 Developer Survey on October 6, 2026. More than 30,000 people took part over seven weeks. The results show that AI coding assistants and agents are now daily tools for most developers who use them, while trust in AI output still depends on whether developers can check it. For companies that hire software firms, the findings help set realistic expectations about what AI-assisted development changes and what it does not.
Key findings
From the Stack Overflow announcement and the survey's AI results page:
- Daily use: 73% of respondents who use AI coding assistants or agents use them daily.
- Tools: among AI users, coding agents (66%) and chatbots (63%) are the most common. The most used agents are Claude Code (66%) and GitHub Copilot (59%).
- Tasks: AI is mainly used for generating code in familiar areas (67%) and debugging (61%).
- Sentiment: 62% of all respondents view AI at least somewhat positively, rising to 71% among daily users.
- Trust: the AI results page reports that 48% trust AI when they can easily validate the answers, and the announcement says 93% need source attribution to trust what AI gives them.
- Skills and doubts: 79% want to improve their AI skills, while the AI page notes that six in ten users cite at least one reason to avoid AI.
Outside AI, JavaScript remains the most used language at 62%, and SQL now ranks second, passing HTML/CSS. Only 18% of developers go into an office every day, and the share working in an organization of one rose from 4% to 10%.
Why it matters for companies hiring IT firms
If most developers who use AI do so every day, it is reasonable to ask any development partner how they use it. The survey suggests the most common uses are writing code in areas developers already know and debugging, which supports faster delivery of routine work rather than replacing engineering judgment. The trust findings matter for quality: developers trust AI most when they can verify its output, so ask vendors about code review, automated testing and how AI-generated code is checked before it reaches your product.
Data handling is the other question. If a software development company uses AI agents on your codebase, agree in writing which tools are approved, whether your code may be sent to external services, and how secrets such as API keys are protected.
Why it matters for IT firms
For development firms, AI tooling is now an expected part of the workflow, and clients will compare how firms use it. Clear policies on approved tools, review practices and attribution can become a strength in proposals. The finding that most developers want to improve their AI skills points to a training need inside teams, and the concern about losing skills suggests that training should cover fundamentals as well as tools. The rise in respondents working in organizations of one is also worth watching for firms that compete with freelancers.
What to do next
- Buyers: add questions about AI use, code review and data protection to your RFPs and vendor assessments.
- Providers: document your AI-assisted development process and share it with clients before they ask.
- Both: agree in contracts how AI-generated code is tested, attributed and owned.
