Thanks @Aryan-Pillai7 for this comprehensive comparison! 🙌

The feature matrix is clear and highlights our strengths well. A few suggestions:

1. Snyk AIBOM — could you add a note that their feature is currently in early access/limited preview? Their public docs are indeed sparse.
2. Cisco AIBOM — they actually released an update last week (Cisco Live EMEA) — might be worth checking if their scanner count has changed.
3. Consider adding a "Best For" row to guide users (e.g., ai-bom = multi-framework/multiformat, Cisco = Python/LLM-enrichment, Snyk = existing Snyk customers).

Overall great work — this addresses issue #37 perfectly. Happy to merge after these tweaks!

Thanks for the contribution! The markdown in docs/comparison.md has escaped special characters (\# instead of #, \\ instead of **, \- instead of -). These escape sequences prevent proper rendering — headers won't display as headers, bold text won't be bold, and lists won't format correctly.

Please remove the backslash escapes so the markdown renders properly. For example:

• \# AI-BOM Tool Comparison → # AI-BOM Tool Comparison
• \*\*ai-bom\*\* → **ai-bom**
• \- Open-source → - Open-source

Once fixed, happy to merge!

Hi @Zie619
I checked the Cisco AIBOM 0.3.0 release notes here:
https://github.com/cisco-ai-defense/aibom/releases/tag/0.3.0 and also went through the docs

I couldn't see any updates related to additional scanners (still appears to be 1), so I’ve kept the scanner count unchanged in the comparison.md . Please feel free to double-check on your end as well in case I missed anything

Appreciate your input!

Thanks for the updates @Aryan-Pillai7! The markdown formatting looks clean now, the Snyk "early access" note is there, and the "Best For" row is a nice touch.

Cisco scanner count confirmed as still 1 — you're right.

This looks good to merge 👍 — will merge shortly.

All feedback addressed. LGTM!
