Claude Code Adoption Expands Across Enterprise and Developer Tools

Claude Code has seen broad adoption since its general release, with Anthropic reporting increased usage and integration across multiple platforms and industries.

Anthropic first released Claude Code in February 2025 alongside Claude 3.7, later making it generally available in May 2025 with the rollout of Claude 4. The tool was initially designed to assist with coding tasks and has since expanded its capabilities and reach.

By October 2025, Anthropic introduced a web-based version of Claude Code, which was also accessible through its iOS application. This allowed users to perform coding tasks directly from browsers and mobile devices, broadening access beyond traditional development environments.

Claude Code supports integration with various development tools, including terminals, IDEs such as VS Code and JetBrains, as well as web and mobile interfaces. Its functions include reading, writing, and overwriting files, searching directories, running shell commands, executing test suites, inspecting outputs, and generating multi-file patches.

What the numbers show

• Enterprise adoption increased 5.5× by July 2025
• Annual run-rate revenue reached $1 billion by November 2025
• Claude Code generated 90% of Anthropic’s own code
• Productivity per engineer at Anthropic rose by 67%

In December 2025, Anthropic integrated Claude Code into Slack as a beta research preview. This feature enabled users to tag Claude in coding-related Slack threads, triggering coding tasks that used context from ongoing conversations and authenticated code repositories.

Anthropic also launched Claude Code as a web-based tool for Pro and Max subscribers in October 2025. This version included secure GitHub integration, allowing users to clone repositories, run tests, and create pull requests directly from their browsers.

By January 2026, Anthropic introduced 'Cowork', a graphical interface for Claude Code aimed at non-technical users. This development expanded the tool’s accessibility to a broader user base beyond software engineers.

Internally, Anthropic reported that Claude Code was used to generate 90% of its own code and that per-engineer productivity increased by 67% even as the engineering team doubled in size. Companies such as Workera adopted Claude Code in place of other tools, and its use became nearly universal among technical staff at Anthropic.

Claude Code has evolved from an autocomplete tool into a system capable of handling end-to-end coding tasks through natural-language prompts, particularly after the release of the Claude Opus 4.5 model. This shift has enabled more complex and agentic coding workflows for a range of users.
