See it run

Live runs and signed replays.

The cockpit shows the agent driving in plain English with EA1 gating each step. Every session is scrubbable and signed, so a human reviewer can replay exactly what happened.

Real recording, not staged: the Human-in-the-Loop suite runs live — EA1 pauses a destructive action for a real Approve / Deny decision — then every session replays scrubbable and every policy decision lands in the signed audit log.

What matters

Three reasons teams switch.

Safe

Destructive actions are blocked by default.

Delete, purchase, transfer: blocked by default. No flag, no programmatic override, no permissive mode — the only way one runs is a human watching live approving that exact action. Playwright and Playwright MCP have no equivalent gate at all. Every step is policy-checked and logged in a tamper-proof audit trail. Learn about EA1 →

Fast

~13 ms per step. 2–5× faster than Playwright MCP.

Your agent verifies as fast as it can think. Zero-IPC means no CDP round-trip per action. More iterations per dollar, longer autonomous sessions. Run the benchmark →

Private

Runs entirely on your machine.

No cloud. No telemetry. No data leaves localhost. One signed binary download, then fully offline. Air-gap ready for regulated and defense environments.

Side by side

Different tools, different jobs.

We built Alethia for agent-driven verification of Chromium-targeting web apps — that's a deliberate scope, not a gap. It goes deep on safety, compliance, and agent performance where Playwright MCP doesn't. Cross-browser coverage and multi-language bindings are out of scope by design; the table below shows exactly where Alethia and Playwright MCP each win.

Safety
Fail-closed EA1 safety gate ✓ ✗
Fail-closed origin allowlist (never arbitrary URLs) ✓ ✗
Kill switch (emergency halt) ✓ ✗
Per-action human approval (live, not a config flag) ✓ ✗
Compliance & Evidence
Tamper-proof signed audit pack (Ed25519) ✓ ✗
Per-step integrity fingerprint (SHA-256) ✓ ✗
Accessibility audit (WCAG 2.1 AA via axe-core) ✓ ✗
Performance
Typical call (ms) ~13 ms ~200 ms
Agent-native MCP interface ✓ ✓
Zero-IPC in-process execution ✓ ✗
Scope
Plain-English test authoring ✓ native ✗
Cross-browser (Firefox, WebKit) ✗ by design ✓

Every feature row is verifiable against the respective runtime's source or tools. The benchmark numbers come from our reproducibility kit; every dev can re-run it locally and get their own numbers.

Who it's for

Built for the teams building AI agents.

Agent tool builders

Give your agents eyes and hands in the browser.

Embed Alethia in your agent's decide-act-verify loop. Plain English in, structured results out. Compact bundled snapshots instead of per-action accessibility trees that grow with page size.

Enterprise & regulated teams

Air-gapped. Auditable. U.S.-built.

No data leaves your infrastructure. Cryptographically signed audit trails. U.S. patent, U.S. company, no foreign filings. Built for defense, federal, and regulated environments.

Go deeper

There's more under the hood.

Alethia's architecture is designed from scratch for AI agents, not adapted from human test tooling. Explore the details when you're ready.

Architecture

Why Alethia is different →

Zero-IPC execution, agent perception layer, DOM diffs, smart assertions, conditional steps. 10 capabilities that CDP tools can't replicate.

Safety

VITRON-EA1 safety standard →

The first browser automation framework with built-in runtime-enforced ethical guardrails. Destructive actions blocked by default, cryptographically audited.
