According to a recent report, Stack Overflow is facing a steep decline in usage, with question volume plummeting to levels not seen since its launch in 2009. The analysis points to a combination of factors, including changes to moderation policies around 2014 and, more significantly, the rise of Large Language Models (LLMs) like ChatGPT, which provide faster and more readily available answers to developer questions, effectively accelerating the platform’s decline and leading many to believe its days are numbered.
Stack Overflow’s initial success stemmed from its ability to foster a vibrant community of developers who freely shared their knowledge and expertise. The platform quickly became an indispensable resource for programmers of all skill levels, providing a centralised repository of solutions to common coding problems. The platform’s initial focus on open collaboration and community-driven content was a key differentiator, encouraging users to ask questions, share their knowledge, and contribute to the collective wisdom of the community. This created a virtuous cycle, where the platform became more valuable as more people participated.
Questions on Stack Overflow began to decline around 2014, coinciding with increased moderator efficiency through more frequent closures and the removal of low-quality posts, which ultimately created a less welcoming environment for some users. This change in moderation style altered the dynamic, contributing to a gradual decrease in question volume. The rise of alternative Q&A platforms and online communities also contributed to the decline in Stack Overflow’s market share, as developers now have a wider range of options for finding answers to their questions and connecting with other programmers.
In March 2020, the onset of pandemic-related lockdowns triggered a temporary surge in traffic as developers sought solutions to new challenges. However, this increase proved short-lived, with question volume declining again before the public release of OpenAI’s ChatGPT. The launch of ChatGPT in November 2022 dramatically accelerated the decline in questions asked on Stack Overflow, as the AI chatbot’s speed and training on Stack Overflow data provided comparable, and often more accessible, answers.
By May 2025, the number of questions submitted to Stack Overflow had fallen to levels comparable to those seen in the platform’s early months, indicating a significant decrease in activity and raising questions about its future viability. The platform now faces a critical juncture, with potential outcomes ranging from acquisition to complete shutdown. This economic climate adds further pressure on platforms like Stack Overflow to adapt and demonstrate continued value, as Microsoft and other companies implement layoffs as part of broader restructuring efforts.
AI tools are increasingly demonstrating the potential to significantly boost developer productivity by automating repetitive tasks and providing instant access to information, allowing developers to focus on more complex and creative aspects of their work. Cursor, a coding assistant, reports positive results from early access users, indicating a growing market for AI-powered development tools. The emergence of AI presents an opportunity for Stack Overflow to leverage its existing community and content to build tools that complement, rather than replace, human interaction.
The platform’s ability to attract and retain a diverse community of developers is crucial for its long-term success. Stack Overflow must create a welcoming and inclusive environment for programmers of all skill levels, backgrounds, and experiences. The integration of AI-powered tools into the Stack Overflow platform could enhance the user experience, with AI used to automatically tag and categorise questions, recommend relevant answers, and provide personalised learning recommendations.
Stack Overflow’s legacy as a pioneering online Q&A platform is secure, having played a significant role in shaping the software development landscape and empowering countless programmers around the world. However, its future remains uncertain, and its long-term success will depend on its ability to adapt to the changing needs of the developer community. Stack Overflow’s future may involve a shift in focus from simply answering questions to providing more comprehensive learning resources and educational content, leveraging its existing content and community expertise to create online courses, tutorials, and other learning materials.
