deepsec vs plannotator

The two are close in size: 7.9k stars for deepsec, 8.4k for plannotator. Over the days we have tracked them deepsec moved +154.8% and plannotator +41.8%, so deepsec is growing faster right now.

They split the axes: deepsec leads on context depth and noise control and customization, plannotator on setup ease.

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.

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
Diff-focused
Noise control
How it keeps output volume down — severity thresholds, deduplication, incremental runs over new commits only.
Revalidate + matchers
No noise controls
Customization
How far it bends to your team: custom rules, prompts, style guides, per-path config.
Plugins & matchers

Privacy
Whether your code stays on your own infrastructure: fully local, self-hostable, or cloud API only.
