Why Crawlens

We built Crawlens to make web changes understandable

Teams do not lose because they miss every issue. They lose because they cannot prioritize signal over noise fast enough. Crawlens exists to make change visible, measurable, and actionable.

See what changed

Detect visual and performance drift before customers do.

Understand what matters

Group noisy alerts into decision-ready incidents with context.

Ship with confidence

Turn release risk into measurable quality gates for every stakeholder.

The Problem

Visual Testing Is Broken

Every team ships CSS changes. Most find out something broke from their users — not their tools.

Silent UI Breaks

A CSS change broke your checkout page. 10,000 users saw it before your team did.

Alert Fatigue

Your footer changed. You got 147 separate alerts. You ignored all of them.

Manual QA Is a Bottleneck

Screenshot comparison by hand takes hours. And you still miss things.

Code vs Visual

100 Lines of Assertions vs 1 Snapshot Signal

Show the difference between brittle UI assertions and visual evidence that teams can act on immediately.

Traditional Unit/UI Tests

Long tests, partial confidence

test('checkout button is visible', async () => {
  await page.goto('/checkout')
  await page.waitForSelector('[data-qa=checkout]')
  await expect(page.locator('#checkout')).toBeVisible()
  await expect(page.locator('#checkout')).toHaveText('Complete Payment')
  await expect(page.locator('#checkout')).toHaveCSS('margin-top', '0px')
  // ...94 more assertions for breakpoints and states
})

High maintenance with brittle selectors and limited layout awareness.

Crawlens Snapshot

One visual proof, full context

Not every buyer knows advanced QA language. Visual RegressionUnexpected UI changes introduced after a code update. and INPInteraction to Next Paint. Measures UI response speed after user input. terms can be explained inline to lower friction and speed adoption.

Why this matters

Micro-explanations reduce cognitive load and keep non-technical stakeholders engaged.

SEO upside

Educational copy around key terms improves semantic relevance for high-intent searches.

Sales enablement

Buyers understand value faster when product language is translated into outcomes.

Enterprise Readiness

Built for cross-functional buying decisions

Product, engineering, and operations teams get one platform with clear controls, observable outputs, and plan-aware governance.

Policy-ready controls

Role-aware access, scoped integrations, and explicit plan gates for predictable rollout behavior.

Integration governance

Webhook and API access are constrained by org and plan limits, reducing accidental blast radius.

Operational visibility

Batch lifecycle, queue depth, and performance snapshots make release risk measurable.

Scalable execution model

Workflow orchestration + worker isolation supports gradual scale without full rewrites.

Phase 1 Decision Layer

Detect, prioritize, and act with one Decision Brief

Snapshots detect quality drift. Analytics quantifies impact. Teams get one decision brief with ranked priorities and ownership context.

Decision flow

Detect

Catch drift before customers do

Continuous snapshots monitor visual and performance regressions across critical journeys.

Prioritize

Rank issues by business impact

Analytics weighs affected sessions, goal drop risk, and confidence so teams know what to fix first.

Decide

Prepare the decision packet

Decision Brief consolidates evidence, ownership, and deadline context for release review.

Enterprise proof packet

Monitoring + Analytics Decision Brief

A single executive-ready output for release reviews, incident standups, and go/no-go calls.

Phase 2 Execution Narrative

Insight -> Action -> Proof in one enterprise loop

Turn Web Analytics insights into guided workflow execution, then close the loop with proof artifacts stakeholders can audit.

Insight

Role-aware anomaly and performance summaries surface what changed and why it matters.

Action

Owners launch the right playbook directly from insight context without switching tools.

Proof

Every workflow run maps to auditable outcome evidence for release and business review.

Buyer Alignment

Value narrative for each stakeholder

The same platform answers different buying questions across product, engineering, growth, and operations.

Engineering Manager

Primary pain

Release risk grows with UI surface and team count.

Business outcome

Consolidated visual + performance quality gate per release.

QA / Platform

Primary pain

Manual regression checks are slow and inconsistent.

Business outcome

Automated batch workflows with deterministic lifecycle states.

Growth / Product

Primary pain

Conversion changes are hard to attribute to UI and performance shifts.

Business outcome

Journey, funnel, attribution, and revenue surfaces in one analytics model.

Ops / Leadership

Primary pain

Hard to understand real operational risk before launch.

Business outcome

Queue, SLO, and grouped-incident outputs support faster go/no-go decisions.

Proof and Outcomes

From feature claim to operational evidence

Capability messaging is backed by concrete payload shapes and decision-oriented outputs.
