| Integrations | Intel documents integrations with Microsoft Visual Studio and Eclipse; Linux installation also offers an Eclipse integration option. | The app uses Firebase services for crash reporting, performance monitoring, analytics, remote configuration, authentication, and cloud data storage. |
| Notable limitation | Intel states that Platform Profiler reached its final release in VTune 2025.0 and will receive no further feature improvements or security fixes. | Some older vehicles may not support VIN readout. |
| Purpose | VTune Profiler analyzes application and system performance to help find bottlenecks across AI, HPC, cloud, IoT, media, and storage workloads. | Piston turns an Android mobile device into a car scanner for reading diagnostic trouble codes and Freeze Frame data. |
| Security | Some analyses require administrator or root privileges, and Intel advises limiting access to the Linux sampling driver because collected system metrics may expose sensitive information. | The privacy policy says data sent to remote servers is encrypted and the app uses the Play Integrity API. |
| Support | Intel directs users to product documentation, forums, and support resources; active oneAPI Priority Support customers can open a support ticket for the toolkit. | Support is available by email at [email protected]. |

In their own words
Intel VTune Profiler
Intel VTune Profiler analyzes application and system performance to help locate bottlenecks in AI, HPC, cloud, IoT, media and storage workloads. It profiles CPUs, GPUs and NPUs, including through a unified XPU Offload Analysis view. Hotspot analysis finds time-consuming code, and Flame Graphs display hot code paths. Microarchitecture exploration identifies hardware performance issues, while memory analysis can reveal cache misses and bandwidth problems. Intel lists support for SYCL, C, C++, C#, Fortran, OpenCL, Python, Go, Java, .NET and Assembly, including mixed-language applications. The profiler is available as a standalone download or through the Intel oneAPI Toolkit, with integrations documented for Microsoft Visual Studio and Eclipse. The 2026.4 release is listed for 64-bit Windows and Linux hosts. Its Linux-only AI Assistant can run collections, report analyses and suggest bottleneck optimizations using the user’s own LLM access; Intel cautions that suggestions may be inaccurate. Some analyses need administrator or root privileges. The tool is free to download and use for commercial and non-commercial purposes.
Piston
Piston is an Android app that turns a phone into a scanner for vehicle diagnostics. It works with OBD-II and EOBD vehicles through a separate ELM327 adapter connected by Bluetooth or WiFi. The free plan costs nothing and includes reading and clearing diagnostic trouble codes, viewing Freeze Frame data, and reading real-time sensor data. Access is limited to information the vehicle provides through OBD2. Premium adds sensor charts, CSV export, Readiness Monitors, fault history, cloud sync, and VIN reading. Some older vehicles may not support VIN readout. Piston uses Firebase services for crash reporting, monitoring, analytics, authentication, remote configuration, and cloud storage. Settings provide opt-outs for several data services, and account deletion permanently removes associated data.
