deepsec vs mantis
deepsec is much bigger: 7.9k stars against 935. Over the days we have tracked them deepsec moved +154.8% and mantis +10288.9%, so mantis is growing faster right now.
mantis leads on model freedom. deepsec does not take any axis by a clear margin.
Stars and commit dates come from our own daily tracking. The six axes are read off each project's documentation by our review pipeline, so they describe what a project says about itself, not what we measured in its code.
Where they stand today
Agent-powered whole-repo vulnerability scanner that scales across workers, resumes interrupted runs, and lets you grow project-specific matchers.

Six axes, head to head
Each axis runs 0 to 5. The label under a score is what that project's own docs claim, not a category average.
| Axis | deepsec | mantis |
|---|---|---|
Context depth How much of your codebase it sees before it answers: the open diff, the diff plus related files, or the whole repository. | ●●●●● Whole-repo analysis | ●●●●● Whole-repo analysis |
Noise control How it keeps output volume down — severity thresholds, deduplication, incremental runs over new commits only. | ●●●●● Revalidate + matchers | ●●●●● Dedupe & filters |
Customization How far it bends to your team: custom rules, prompts, style guides, per-path config. | ●●●●● Plugins & matchers | ●●●●● Customizable prompts |
Privacy Whether your code stays on your own infrastructure: fully local, self-hostable, or cloud API only. | ●●●●● Cloud APIs with key | ●●●●● Self-hostable |
Model freedom Whether you can point it at any provider, or it is wired to one. | ●●●●● BYOK & providers | ●●●●● Bring-your-own-key |
Setup ease What it takes to get a first useful run out of it. | ●●●●● Config + API key | ●●●●● Agent + API key |
