Every team has
scattered secrets.
FyVault was not born in a vacuum. It came from real frustrations building Fyboard at Fybyte — the same frustrations every engineering team knows but nobody talks about.
We were building Fyboard.
Secrets were everywhere.
Dozens of microservices. Hundreds of secrets. Every single one was a .env file sitting in plaintext. Stripe keys in the repo root. Database passwords in Slack threads. AWS credentials copy-pasted into Notion pages.
We had rotation policies that nobody followed and audit trails that did not exist. The worst part was knowing it was wrong and still not fixing it, because the fix always felt bigger than the thing we were actually building.

HashiCorp Vault
Powerful, but needs a dedicated ops team
Doppler
Clean UI, but per-seat pricing and no runtime layer
1Password
Great for humans, terrible for machines
Common failure
No runtime protection. Secrets land in
process memory the moment they are fetched.
We tried everything.
Nothing solved the real problem.
We evaluated every vault, every manager, every SaaS tool that promised to fix secret sprawl. Each one solved part of it. None of them solved the part that mattered most.
Every tool encrypted secrets at rest. But the moment our app fetched a secret, it was plaintext in process memory. That is where breaches happen — not in the vault, but in the app.
49% of data breaches involve credentials. The vault is never what gets compromised — it is the application that reads from it.
What if secrets never
entered application memory
at all?
That question changed everything. Every other tool we evaluated worked the same way: store the secret, encrypt it at rest, hand it to the application when asked. But from that moment, the secret was just a string in process memory.
Breach surface exposed
Zero exposure
That is when we started building FyVault. Not another vault. A runtime. A system where secrets flow through the kernel, not your code.
Seven milestones.
Each one solved a real problem.
We started with the hardest problem — kernel-level secret injection on Linux. Then we expanded outward. Each milestone solved a real problem our own team was hitting while building Fyboard.
eBPF Kernel Injection
Linux agent intercepts syscalls at the kernel boundary. Secrets never exist in application memory — they are injected at the lowest level the OS provides.
Node.js + Python SDK
One import. One call. Works in any runtime. Developers should not need to learn a new paradigm to use real encryption.
CLI with 40+ Commands
Local dev, CI/CD, automation. Fully scriptable. Every operation available from the command line, no UI required.
Zero-Knowledge Encryption
Client-side AES-256-GCM. We cannot read your secrets. Nobody can. The encryption key never leaves your device.
Agent Credentials
Purpose-built tokens for AI agents. Scoped permissions, automatic expiry. Because AI tools should not use your personal keys.
MCP Server
AI tools become vault-aware. Secrets resolve at runtime without ever appearing in prompts, logs, or context windows.
30+ Integrations
Vercel, AWS, Docker, Kubernetes, Terraform, GitHub Actions, and more. Secrets flow to every platform your team uses.
What we stand for.
Building FyVault forced us to decide what we believed in. These are the convictions we wrote down early and have never compromised on.
We Believe
We Refuse

FyVault is live on Linux, macOS, and Windows. The SDK works in Node.js and Python. The CLI has 40+ commands. But we are just getting started.
