Odin Docs Muninn Docs Heimdall Docs About Developer

Open-source compliance tools built for EHS professionals who need reliable, local-first software. Each tool ships as a single Go binary with zero runtime dependencies — use them standalone or together through shared configuration.

Local-First Your data stays on your machine. No cloud accounts, no subscriptions.

Zero Dependencies Single binaries. Download, run, done.

Graceful Degradation Every tool works alone. Integration is a bonus, not a requirement.

Each tool is standalone — no daemons, no IPC, no message bus. Heimdall is a shared Go library that provides a single source of truth for configuration across all tools, with schema validation and change notifications. Tools also share vault directories and databases on disk.

Every tool works independently. Shared configuration is a convenience, not a dependency.

Getting Started

Muninn is the first tool ready for use. Install it and start capturing knowledge:

go install github.com/asgardehs/muninn@latest

See the Muninn documentation for setup and usage.
