Launch Live Terminal
Browser security policies often block embedded terminals. Click below to instantly launch a fully configured, zero-setup browser IDE in a new tab where you can type commands natively.
Hash-Chained Audit
Every scan appends an entry to a cryptographically chained log. Editing or deleting past entries breaks the chain instantly.
Post-Quantum Ready
Optionally dual-sign every entry using Ed25519 and ML-DSA65. Uses Go 1.27's native crypto/mldsa—no external lattice code.
Remote Anchoring
Cross-check local chains against a separate, trusted anchor server using authenticated HTTP receipts to detect entire log replacements.
