AI-assisted development in 2026 is moving from code suggestions toward agents that can take on connected steps such as implementation, testing, documentation, and review. Adoption is widespread among surveyed professional developers, but the evidence points to assistance—not autonomous software engineering: people still set direction, validate results, and own the outcome.
How widely are developers using AI coding agents?
JetBrains Research’s 2026 Developer Ecosystem Survey, which covered more than 15,000 professional developers worldwide, found that 90% used AI coding agents at work at least weekly and 68% used them daily during the May–July 2026 collection period. These are survey results for that population and period, not a census of developers everywhere.
In the same survey, respondents reported workplace use of these coding tools:
| Tool | Reported workplace use |
|---|---|
| Claude Code | 39% |
| GitHub Copilot | 21% |
| Codex | 16% |
| Cursor | 12% |
| JetBrains AI | About 9% |
| OpenCode | 7% |
These are reported adoption rates among survey respondents, not market shares or a permanent ranking. JetBrains’ separate January 2026 AI Pulse report found that 90% of respondents regularly used at least one AI tool for coding and development at work, while 74% had adopted specialized developer AI tools. Those earlier figures measure different categories and should not be treated as a continuation of the agent-specific May–July results.
What is changing in the development workflow?
From suggestions to multi-step work
The central shift is from tools that answer a prompt or complete a line of code to systems that can work through a sequence: interpret a task, propose or make changes, run tests, and help review the result. Gartner describes enterprise coding agents as spanning planning, code creation, and review. That wider scope can reduce the number of steps a developer performs manually, but it does not remove the need to define the task or judge whether the result is correct.
Developers are becoming coordinators and reviewers
As agents take on more connected tasks, the human contribution increasingly includes breaking work into manageable pieces, giving agents context, choosing what to delegate, and checking whether the changes solve the intended problem. Anthropic’s 2026 report says engineers use AI in roughly 60% of their work but report being able to fully delegate only 0–20% of tasks. That is a finding from Anthropic’s research, not a population-wide statistic, but it illustrates the gap between frequent assistance and handing over responsibility.
Anthropic also predicts that specialized agents will work in parallel and that some agent tasks will last longer than the short interactions common in chat. Its report describes the need for task decomposition, coordination protocols, visibility into concurrent sessions, and version-control practices for simultaneous contributions. These are forecasts and design challenges, not evidence that every current coding agent can reliably handle work for days or weeks.

Stack Overflow’s 2026 survey asked what developers use AI for. Respondents most often reported tasks where the output can be compared with familiar code, a known problem, or a test:
| Use reported by respondents | Share |
|---|---|
| Generating code in a familiar area | 69.3% |
| Debugging, troubleshooting, or refactoring | 63.8% |
| Answering straightforward technical questions | 59.4% |
| Writing or improving tests | 58.1% |
The pattern matters: familiarity and the ability to validate an answer shape where developers are willing to use AI. Stack Overflow also found that developers are most comfortable when they can check the output. AI can make more technical work approachable, but a plausible-looking answer is not proof that it is right.
Will AI make software teams faster?
Not automatically. Google DORA’s 2025 research drew on more than 100 hours of qualitative research and responses from nearly 5,000 technology professionals around the world. DORA characterizes AI as an amplifier of an organization’s existing strengths and dysfunctions. That finding argues against treating tool adoption or increased code output as direct evidence of faster delivery, better software, or better team performance.
For teams, the practical question is whether AI fits into a workflow with clear requirements, useful tests, maintainable code, and timely review. If those foundations are weak, agents can increase the volume of changes that need attention without fixing the underlying process. DORA’s evidence is from 2025, so it should not be mistaken for a 2026 survey result.

Why are quality, security, and governance becoming more important?
More autonomy increases the importance of controls around the work. In July 2026, eu-LISA said AI coding assistants may support productivity gains while calling for attention to code quality and security, regular evaluation of tools, and adequate resources to review generated code. Review is not an optional cleanup step: it is part of how an organization determines whether a change is safe and fit to ship.
Gartner’s 2026 enterprise analysis likewise broadens the evaluation beyond which model writes the strongest code. It highlights governance, pricing, customer support, workflow fit, commercial maturity, and market durability. Gartner analyst Philip Walsh summarized the shift: “What began as a race to deliver the most ’magical’ developer experience is now evolving into a contest of operational excellence, commercial maturity, and enterprise readiness.” For a buyer, integration and the ability to inspect and approve changes can matter as much as raw coding capability.

A useful evaluation starts with the work the team wants to delegate, then checks whether people can control and verify the agent’s contribution. Assess:
- Task scope: Does the tool provide autocomplete and chat, or can it plan and carry out multi-step implementation, testing, or review?
- Workflow fit: Does it work in the team’s IDE, command line, cloud environment, repository, and collaboration process?
- Human control: Can developers inspect proposed changes, set approval points, and understand what the agent did?
- Quality and security: Are testing, code review, security review, and ongoing tool evaluation part of the workflow?
- Enterprise readiness: Are governance, privacy, support, procurement, and deployment requirements clear?
- Cost predictability: Are pricing and usage limits understandable for the team’s expected workload? Check current terms directly because they can change.
These criteria reflect the broader enterprise considerations identified by Gartner and the importance developers place on output quality and integration in Stack Overflow’s survey. They also help separate a compelling demo from a tool that can be responsibly used in production work.
Will AI coding reach people outside engineering?
Anthropic predicts that agentic coding will reach more non-engineering users, including people in operations, design, cybersecurity, and data science. This points to an expanding set of people who may be able to prototype or automate technical tasks. It does not establish that non-specialists can safely build arbitrary production systems without engineering oversight. The same requirements for validation, security, and ownership apply regardless of who starts the work.
What does Gartner expect by 2027?
Gartner forecasts that by 2027 more than 65% of engineering teams using agentic coding will treat IDEs as optional. This is a forecast, not a measured 2026 outcome. It signals a possible change in where engineering work happens as agents operate across tools and stages of development; it does not mean that IDEs will disappear or that teams will no longer need developers.
