I’d like to share a tool I’ve been working on called MemBrowse: a firmware memory footprint tracking platform.
It plugs into GitHub Actions, parses ELF + linker script after the build step, and uploads memory reports to a dashboard. The main benefit of MemBrowse is the persistent historical dashboard with a friendly interface where you can browse memory usage per region, section, symbol, and library across commits and targets. It also helps profile and understand on a library/module level where the bloat is actually coming from.
A few things it adds:
-
Track how flash/RAM usage trends over time and pinpoint which commit introduced growth
-
Compare utilization across board targets side by side
-
Set budget thresholds per memory region and get alerted when a target is getting tight
-
PR comments with the memory delta for reviewers
Here is a dashboard with data from PX4-Autopilot:

It’s free for open source projects. If you find it useful I’d be happy to open a PR with the integration.
