Autonomous QA for Modern Teams.

Launch an AI agent to explore your product, catch regressions, and verify UX before your users do. Integrated directly into your workflow.

Anomoly Detected: UI Consistency

Error message "Invalid ZIP" appears briefly but disappears after 500ms. UX friction confirmed.

The Scripted Blind Spot

  • Visual Regression

    Button is visible but overlaps the headline on mobile resolutions.

  • UX Friction

    "Success" message disappears before user can read it.

  • Logical Ghosting

    Modal closes when clicking outside, losing 10 minutes of input data.

Manual QA doesn't scale.
Unit tests don't think.

Langoustine acts as a detail-oriented human explorer. It finds the edge cases and UX "paper cuts" that your scripted automation was never programmed to look for.

Zero Setup

No test framework required. No scripts to write. Point Langoustine at any URL and it gets to work.

Exploratory

No scripts to maintain. Langoustine learns your app's structure and questions every flow.

Interface

Tell it what to test. In plain English.

Type a goal in the chat and the agent gets to work. The run streams live in the same conversation thread, and results land right there when it's done.

  • Just describe the goal. No configuration, no selectors, no test scripts to write.

  • Live narration. Watch the agent describe each step as it happens.

  • Results in the thread. Findings, screenshots, and severity report come back inline.

Langoustine Chat

Test the sign up flow

I'll test the sign up form with invalid and valid data, check error handling, and verify the confirmation email gets delivered.

Linear-Native Workflow

Webhook Triggered

A Linear issue moves to your QA state → Langoustine starts a run automatically.

Sub-Issues Filed

Every bug the agent finds becomes a Linear sub-issue, linked back to the original ticket.

Bidirectional Sync

Run URLs, findings, and status post back to Linear in real time.

Integration Workflow

How Langoustine Works

01

Connect Environment

Point Langoustine to your staging or production endpoint. No code changes required.

02

Trigger a Run — Your Way

Chat with the AI assistant in plain English, trigger from a Linear issue, or automate via status changes. Langoustine fits into the workflow you already have.

03

Agent Explores & Records

The agent narrates its intent live, takes screenshots, and records a video clip of every step — so you see exactly what it did and why.

04

Structured Report + Linear Sub-Issues

A dedicated Reviewer agent synthesizes findings into High / Medium / Low severity categories with reproduction steps. Optionally, bugs can be automatically filed as Linear sub-issues, linked back to the original ticket.

Product Intelligence

Documents your product.
Gets smarter every run.

As the agent explores, it builds up a living knowledge base of your product — its flows, its quirks, its edge cases. That knowledge feeds back into every future run, so coverage grows automatically without you writing a single line.

Self-Documenting

The agent writes down what it learns about your product's structure and behavior.

Runs Faster Over Time

Every run teaches it more — shared test accounts, known URLs, familiar flows. Less time exploring, more time finding bugs.

Customizable

Override or extend its knowledge with per-project instruction files. You stay in control.

Analysis Vector

Uncovering what scripts miss.

A dedicated observer that understands visual hierarchy, state, and human-centric UX patterns.

Visual Consistency

Visual Regressions

Detects overlapping elements, broken layouts, and inconsistent styling across viewports.

User Experience

UX Friction

Identifies confusing flows, missing feedback, and interactions that "just feel wrong."

Validation

Edge-Case Logic

Questions complex state changes and form validations that scripts often ignore.

Accessibility

A11y Constraints

Highlights missing ARIA labels, poor contrast, and keyboard navigation blockers.

End-to-End Coverage

Email Flow Testing

The agent receives emails your app sends — password resets, confirmations, notifications — and validates the full flow.

Full Observability

Step-by-Step Video

Every agent action is recorded as a video clip. Replay exactly what the browser did, step by step.
