About Custodyn.app and JavaScript.com

In their own words, as submitted to SaaSHub.

Custodyn.app
JavaScript.com

Custodyn is a runtime security and trust infrastructure platform for AI agents. As AI agents become autonomous — executing code, sending emails, making API calls, and taking real-world actions without human oversight — the security risks are real and largely ungoverned. Custodyn sits inside agent...

Questions & Answers

As answered by people managing Custodyn.app and JavaScript.com.

Why should a person choose your product over its competitors?

Custodyn.app's answer

Most AI security tools sit outside the agent — monitoring network traffic or endpoint activity. Custodyn sits inside the agent code itself. It's developer-first, open-core, and self-serve — pip install or npm install and you're running in minutes. No demo call, no sales process. The MIT licensed SDK means developers adopt it freely, the paid platform gives teams policy management, dashboards, and audit compliance.

What's the story behind your product?

Custodyn.app's answer

Built by a solo founder with 15+ years in information security and penetration testing. In early 2026, AI agents started taking real-world autonomous actions with no security layer governing them. The July 2026 incidents — OpenAI agent breaching Hugging Face infrastructure, Anthropic's agentic misalignment report — confirmed the problem was real and urgent. Custodyn was built to be the security layer AI agents were missing.

What makes your product unique?

Custodyn.app's answer

Custodyn is the only AI agent security platform that works at the SDK layer — embedded directly inside agent code. Unlike endpoint-based solutions, Custodyn intercepts actions inside custom LangChain, CrewAI, and AutoGen pipelines that no endpoint sensor can reach. Human-in-the-loop approval queues mean dangerous actions wait for human sign-off before executing — not just blocked or allowed, but genuinely governed.

How would you describe the primary audience of your product?

Custodyn.app's answer

Developers and security teams building production AI agent systems using LangChain, CrewAI, AutoGen, OpenAI Agents SDK, MCP, or Claude Code — who need runtime governance, human oversight, and audit trails before deploying agents in high-stakes environments.

Which are the primary technologies used for building your product?

Custodyn.app's answer

Python Flask (backend) SQLite (database) Python SDK (PyPI) JavaScript SDK (npm) Railway (deployment) Razorpay (billing)

Who are some of the biggest customers of your product?

Custodyn.app's answer

No enterprise customers yet - pre-revenue, currently seeking first customers and open to acquisition
