Project Navi builds open-source security tools for teams deploying AI systems. Everything we ship is MIT or AGPL licensed, zero dependencies where possible, and designed to solve problems we hit firsthand standing up production AI infrastructure.

We're community-funded by choice. No venture capital, no corporate sponsors shaping the roadmap. The people who use the tools decide what matters. Your sponsorship keeps it that way.

What your support funds

[navi-sanitize] - Deterministic input sanitization for LLM pipelines. Strips homoglyphs, invisible Unicode, template injection, and path traversal vectors. Zero dependencies. Live on [PyPI].

[grippy] - AI-powered code review with a deterministic security rule engine and codebase knowledge graph. Structured findings, severity scores, pass/fail verdicts. Works with any model.

[navi-bootstrap] - Spec-driven repo scaffolding that ships CI, security scanning, code review, and release pipelines in a single command. Live on [PyPI].

navi-fractal (coming soon) - Audit-grade fractal dimension estimation with refusal semantics. Refuses to emit data without mathematically verified scaling regimes.

Where every dollar goes

Every dollar goes directly to development, documentation, and keeping these tools free for the community. No marketing team, no sales org - just infrastructure that makes safe AI the path of least resistance.

Why we build this way

Seven years in behavioral health research taught us that the systems which help people recover are the same ones that keep complex systems whole. We build governance tooling the same way - empowerment over enforcement, infrastructure over guardrails.

If your team uses our tools or you believe open-source AI security should exist independent of corporate interests, sponsorship is how you make that real.

Machine cognition, human values.
