I’d like to share a tool I’ve been working on called [MemBrowse](https://membrowse.com): 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.
