Engineered with 6 sovereign performance primitives for uncompromising zero-cloud security.
Deterministic finite automata (DFA) regex compiler executing matches in under 300 microseconds with microsecond telemetry and named capture group extraction.
Complete offline inspection of JWT Header, Payload, and Signature. Verifies HMAC-SHA256 signatures with constant-time equality checks without leaking secrets to remote servers.
Chained transformations across Base64, Base64URL, Hex, URL-encoding, JSON prettify/minify, SHA-256, SHA-512, Unix Epoch timestamps, and HTML escaping in a single pass.
Connects natively to Cursor IDE and Claude Desktop via stdio. AI agents can validate regexes, decode tokens, and transform payloads automatically without internet access.
High-speed local Web UI listening on 127.0.0.1:7676. Instant visual match highlighting, cheat-sheet presets, live JWT verification badges, and 0% RAM bloat.
Hardware fingerprint binding coupled with Tier 3 24-hour heartbeat lease. Self-contained standalone binary with zero external runtime dependencies.
Download the standalone 4.3MB binary for Windows, Linux, or macOS. No runtimes, no dependencies, zero configuration required.
