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.

Live Plain English in, deterministic actions out, EA1 gating each step.
Replay Every session scrubbable, every step signed.

What matters

Three reasons teams switch.

Fast

~40 ms per tool call. 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 →

Safe

Destructive actions are blocked by default.

Delete, purchase, transfer: blocked unless explicitly allowed. Every step is policy-checked and logged in a tamper-proof audit trail. Learn about EA1 →

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. If you need cross-browser testing or multi-language bindings, use Playwright. If you need compliance-native agent automation, use Alethia. Pick the one that fits the workload.

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.

Try it

Run the built-in demo.

Alethia ships with demo apps. Ask your agent to serve one and drive it. In Claude Code, the preview panel shows the app being tested in real time.

03

Paste this into Claude Code

Watch the agent drive a real app

Use alethia_serve_demo to start the demo server — it returns a URL like http://127.0.0.1:<port>. Replace <base> below with that URL, then call alethia_tell with the result as one block (the leading "name" line is what shows up in cockpit history):

name claude-code-taskflow demo
navigate to <base>/claude-code-app.html
assert TaskFlow is visible
assert Generated by Claude Code is visible
assert Sign in to TaskFlow is visible
type dev@company.com into the email field
type Engineering into the team field
click Sign in
assert Today is visible
assert Signed in as is visible
type Deploy to production into the new task field
click Add
assert Deploy to production is visible
expect block: click Delete

The agent serves the demo on localhost, drives it with plain English, and EA1 blocks the delete.

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. Fail-closed by default, cryptographically audited.
