| Alternative | Cost | Pros vs. IAR | | :--- | :--- | :--- | | | Free | Modern UI, great for OSS, but less optimized code size. | | Keil MDK | ~$4,000 | Comparable performance, better for Cortex-M. | | CLion | ~$200/yr | Excellent refactoring, but debugging setup is manual. | | IAR Kickstart | Free | Code size limited (usually 8KB or 32KB). Good for evaluation. |
