Autonomous gray-box security auditing with visible lanes, attack-surface state, and evidence-backed findings.

S0 admission -> S1 attack surface -> S2 semantic lanes -> S3 merge -> S4 probing -> S5 findings

TriLane turns one natural-language objective into a staged audit cockpit for authorized local labs, internal codebases, training apps, and bug-bounty targets where you have permission to test.

Run without a global install:

npx trilane@latest app

Or install and launch the desktop app:

npm install -g trilane
trilane doctor
trilane app

Then choose Safe or Lab mode and describe the authorized target:

Penetration test juice-shop, source code is in ~/juice-shop, service is running on localhost:3000. If not, use colima or start the service directly

Free-form AI security agents can drift. TriLane makes the audit state explicit: surfaces are inventoried, lane outputs are merged, risky probes are gated by mode, and final findings are deduplicated before export.

• Builds an attack-surface graph before deep auditing.
• Runs a six-lane semantic audit across identity/auth, injection/client-side sinks, ingress/files/SSRF, business logic, configuration/secrets/crypto, and edge-surface coverage.
• Tracks Scan, Agent, Findings, and Config state in a desktop GUI.
• Probes high-signal variants in Lab Mode when the target is explicitly authorized.
• Deduplicates final findings with severity, evidence, payloads, code paths, and report export.
• Archives run transcripts under ~/.trilane/transcripts for regression analysis.

Safe Mode is the default. It is intended for exploration and lower-risk review.

Lab Mode grants the agent broader local filesystem and command execution access for the active target. Use it only on systems you own, operate, or are explicitly authorized to test.

The npm package includes a prebuilt macOS Apple Silicon app bundle so the Dock/Finder icon matches the TriLane brand. Other platforms can still run TriLane from source, or set TRILANE_BIN to a locally built binary:

TRILANE_BIN=/path/to/trilane-gui npx trilane app

Requirements:

• Node.js 20 or newer
• Rust toolchain from trilane-rs/rust-toolchain.toml
• macOS for the current desktop build path

Build the frontend:

cd trilane-rs/trilane-gui/frontend
npm install
npm run build

Build and run the desktop binary:

cd ../../
cargo build -p trilane-gui --release
./target/release/trilane-gui

TriLane is a dual-use security tool. Do not use it against systems where you lack permission. See SECURITY.md for responsible-use boundaries, reporting guidance, and Lab Mode warnings.
