Rider 2026.2.3 Introduces AI Performance Analysis and Fixes
New monitoring features and bug fixes enhance developer productivity.
1AI Performance Analysis Feature
Rider 2026.2.3 introduces AI-powered performance analysis directly in the Monitoring tool window. The feature collects runtime data during application execution, enabling the AI agent to identify bottlenecks and link them to specific code segments. Developers can initiate analysis through the 'Analyze with AI' action, which generates performance insights including time allocation and hot paths in the code. This functionality requires dotUltimate or All Products Pack with the AI Assistant plugin, currently limited to Windows environments.
2Monitoring Tool Integration
The new version integrates AI analysis capabilities with Rider's existing Monitoring tool. Developers can access the feature through the Performance tab charts or via context menus for older snapshots in the dotTrace tool window. The system uses the dottrace-analyze skill to process runtime data, providing actionable insights about application performance. This represents JetBrains' continued investment in AI-assisted development tools within their IDE ecosystem.
3Windows-Specific Requirements
The AI performance analysis feature has specific platform requirements, currently only functioning on Windows systems. Users must have either dotUltimate or the All Products Pack subscription, along with the AI Assistant plugin installed. This limitation reflects the current state of JetBrains' AI tooling development, with potential for cross-platform expansion in future updates. The feature targets professional developers working on performance optimization tasks.
4AI Agent Setup Fix
Version 2026.2.3 resolves a specific issue (RIDER-143160) introduced in the previous release where the AI Agent Setup widget failed to open under certain display scaling conditions. The fix addresses problems occurring when Windows display scaling was set below 175%, ensuring consistent widget accessibility. This maintenance update demonstrates JetBrains' responsiveness to user-reported interface issues in their development tools.
5Update Channels
Users can obtain Rider 2026.2.3 through multiple update channels: directly within the IDE, via the Toolbox App, or by manual download from JetBrains' website. The company encourages user feedback through YouTrack or social media channels. This release follows JetBrains' established pattern of regular, incremental updates to their developer tools with a mix of new features and stability improvements.
6Performance Analysis Workflow
The new AI analysis workflow begins with setting up an analysis request for the most recent session. Developers review and send the automatically generated prompt to initiate the investigation. The AI agent then processes the runtime data to highlight performance characteristics, creating a more efficient debugging process compared to manual performance analysis methods. This feature particularly benefits developers working on complex, performance-sensitive applications.
7Development Tool Evolution
This update continues JetBrains' trend of incorporating AI capabilities into their development tools. The performance analysis feature builds upon existing monitoring infrastructure while introducing new AI-powered insights. It represents a middle ground between fully automated optimization and traditional manual profiling, giving developers more tools to understand application behavior without removing their control over the optimization process.
8Future Implications
The introduction of AI-assisted performance analysis in Rider suggests JetBrains' commitment to integrating machine learning throughout the development lifecycle. As these features mature, they may significantly reduce time spent on performance optimization while improving result quality. The current Windows limitation indicates potential areas for future expansion, possibly including broader platform support and additional analysis capabilities in upcoming releases.
