Thank you Michael, Is there a chance that self-hosted option will be open-source? At least place to store the results? We are very sensitive here and go along only with full open-source solutions.. also try to keep things self-contained and in-house to avoid external dependencies also for security reasons.
Right now our CI seems overloaded with current tasks already, due to CI quotas, because NuttX is really big project. Thus we tend to shrink and cut away things rather than adding new loads. Because of current CI limitations we are working on two independent testing solutions NTFC and NXDART. Current build process already reports binary sizes, we try to perform runtime tests on real world hardware, we have runtime self-test routines and benchmarks. Membrowse seems like a good module here, even if reporting to a different place, because we can then compare our binaries with other OS/RTOS and this I can see as biggest benefit :-) We would have to measure how much load is added on top of current tasks to the CI. I assume no specific permissions are required for membrowse and it will be safe to use? Lup, Raiden what do you think? :-) Thanks :-) Tomek -- CeDeROM, SQ7MHZ, http://www.tomek.cedro.info On Tue, Apr 21, 2026 at 7:10 PM Michael Rogov Papernov <[email protected]> wrote: > > Hi, > > I've opened a pull request: https://github.com/apache/nuttx/pull/18774 > I've added a target from each architecture family supported by Nuttx. > The github workflow uses a github action: > https://github.com/membrowse/membrowse-action > This generates the memory footprint report from the ELF file, the ld script > and the map file, and then uploads it > to membrowse.com where you can see the dashboard. > To your question, Tomak: you can install membrowse with pip (pip install > membrowse) and generate the reports locally.
