PLATFORM CAPABILITIES

ENGINE FEATURES

High-density features designed specifically for Linux terminal session recording, security auditing, and playback.

[01]

ACTIVITY WAVEFORM

Visual telemetry index mapping output density across timeline. Jump directly to active execution spikes.

CAPABILITY METRICREADY

[02]

INSTANT STATE SEEKING

Scrub to any timestamp in the session. Instant PTY state reconstruction without buffering delays.

CAPABILITY METRICREADY

[03]

OUTPUT SEARCH ENGINE

Search stdout/stderr buffer text across recorded sessions with microsecond-accurate timestamp matches.

CAPABILITY METRICREADY

[04]

VARIABLE SPEED PLAYBACK

Adjust playback speed (0.5x, 1x, 2x, 4x, 8x) or skip idle terminal inactivity automatically.

CAPABILITY METRICREADY

[05]

SECRET REDACTION (DLP)

Real-time regex scanning and scrubbing of AWS access keys, JWT bearer tokens, and environment secrets.

CAPABILITY METRICREADY

[06]

SELF-HOSTABLE ENGINE

Deploy via single Docker Compose bundle. Complete data sovereignty with zero external dependencies.

PTY ENGINE

SUB-MILLISECOND LOGGING

Captures native pseudoterminal (PTY) stdout, stdin, and window resize events with microsecond precision.

DLP SCRUBBER

AUTOMATIC REDACTION

Scubs API keys, database credentials, and Bearer tokens before writing session files to disk or cloud.

STATE FORKING

SUBSHELL TIME-TRAVEL

Reconstitutes environment variables and working directory snapshots into a live interactive terminal subshell.

ARCHITECTURE SPECIFICATION

PLATFORM FEATURES

Core execution primitives for high-performance terminal session capture and playback.

GO CORE PTYOVERHEAD: < 2MB

TERMINAL ENGINE

Low-overhead PTY recording binary with real-time DLP secret scrubbing

A high-performance Go CLI binary interfacing directly with system pseudo-terminals (/dev/pty). Captures ANSI color streams, timing offsets, and window resize signals with microsecond timing.

CAPABILITIES

Zero CPU overhead with native Go syscall hooks

Automatic DLP secret redaction before write

Stream compression with instant serialization

Dynamic PTY window resize event synchronization
