Scan. Fix. Verify.

Know if your website actually works.

Test functionality, performance, APIs, accessibility, security configuration and load — then generate an AI-ready prompt to fix the problems.

Built with AI? Verify with DevScan AI.

AI can generate code quickly. It can also quietly break a checkout, ship a 4 MB bundle, or forget a form label. DevScan checks what actually happened on your live site — and hands your agent a precise brief to fix it.

  • It works — pages, links, buttons and APIs
  • It's fast — measured in a real browser
  • Important pages are accessible
  • Configuration issues are caught early
  • APIs respond correctly
  • Changes didn't introduce regressions

# Task: fix issues detected by DevScan AI on Acme Store

## Step 1: Service-breaking / server failures
### 1. [CRITICAL] Checkout page returns a server error (500)
- Affected page: https://acme.example/checkout
- Technical evidence: HTTP 500 on GET /checkout
- Expected outcome: no longer reported on retest

## Constraints
- Only change what is necessary to fix the listed issues.
- Do not guess file names: search for the URLs and errors quoted.

## Testing & verification
- Add or update tests; run the suite; report modified files.

How it works

Website → Scan → Explain → AI Fix Prompt → Fix → Retest → Verify.

  1. Step 1: Enter Your Website

    Add your URL. Basic scans start instantly — verify ownership later for advanced tests.

  2. Step 2: DevScan Tests It

    A real browser crawls your pages and checks functionality, performance, accessibility, SEO, mobile and security configuration.

  3. Step 3: Get Problems + AI Fix Prompt

    Every issue is explained in plain language with evidence, then turned into a precise prompt for your coding agent.

  4. Step 4: Retest and Verify

    Run a retest after the fix. DevScan classifies every issue as fixed, still present, new, or a regression.

Everything a QA engineer would check

Translated into answers anyone can act on — with the technical details one click away.

Functional Testing

Broken links, failed requests, JavaScript errors, missing assets and configurable user flows.

Performance

LCP, CLS, TBT, TTFB and page weight — explained in plain language.

Accessibility

Automated axe-core audits with affected elements and remediation guidance.

Security Configuration

HTTPS/TLS, security headers, cookies, exposed files and leaked API keys — passive and non-destructive.

SEO

Titles, descriptions, headings, canonicals, indexability, sitemaps and structured data.

Mobile Testing

Five device sizes with screenshots and overflow detection.

API Testing

Status, latency, JSON validity and response shape — import from OpenAPI.

Load Testing

Safe k6 presets on verified domains, with automatic abort and live charts.

AI Analysis

Findings deduplicated, grouped and prioritized — secrets redacted before any AI call.

AI Fix Prompt

Ready-to-paste prompts for 18 tools: Claude Code, Cursor, Copilot, Windsurf, Codex, Lovable, ChatGPT and more.

Retesting

Before/after comparison with fixed, still present, new and regression tracking.

Monitoring

Uptime, response time and certificate expiry with deduplicated alerts.

Honest results, safe by design

  • Every report shows its scope: tests performed, tests not performed, pages tested, browser used and limitations.
  • No false guarantees: we say “no critical issues were detected by the checks performed” — never “100% secure”.
  • Non-destructive: no form submissions, purchases, exploits or port scans. Load tests only on verified domains.
  • Your data stays yours: secrets are redacted before AI analysis; credentials and tokens are encrypted at rest.

Frequently asked questions

What does DevScan test?

DevScan crawls your site and tests it in a real Chromium browser: broken links and assets, server errors, JavaScript and network errors, performance lab metrics (LCP, CLS, TBT, TTFB and page weight), automated accessibility rules (axe-core), SEO metadata and indexability, mobile layouts on five screen sizes, and passive security configuration (HTTPS/TLS, security headers, cookies, CORS, commonly exposed files). Paid plans add configurable API checks, user flows, monitoring and load testing.

Can DevScan fix my website automatically?

No. DevScan never changes your code or your site. It finds problems, explains them, and generates a precise prompt you can give to a coding agent such as Claude Code, Cursor, ChatGPT or GitHub Copilot. You stay in control of every change — then you retest to verify.

Why does it generate AI prompts?

Coding agents are fast, but only as good as the instructions they get. DevScan turns technical evidence into a structured prompt with context, evidence, constraints, a safe fix order and verification steps — so agents make focused changes instead of rewriting unrelated code.

Can I test a website I do not own?

Only with permission. Every scan requires you to confirm you are authorized to test the site. Basic scans are passive and lightweight; load testing and other high-impact features require verified domain ownership (DNS, file or meta-tag verification).

What is load testing?

Load testing sends many simulated visitors to your site at once to see how it behaves under traffic. DevScan uses k6 with fixed, safe presets, automatic abort thresholds and an emergency stop — and only on domains you have verified.

What does “concurrent users” mean?

Virtual users are simulated visitors making requests at the same time (about one request per second each in our presets). Results describe behaviour under that specific test configuration — they are not a guarantee of how many real users your site can support.

Does a successful scan guarantee security?

No. DevScan performs passive configuration checks, not a penetration test. A clean result means no issues were detected by the checks performed. Every report lists what was tested, what was not, and the limitations.

How are subscription limits calculated?

Scans, AI Fix Prompts and load credits are counted per billing period (aligned to your subscription's renewal date; calendar month on the Free plan). Quick Scans also have a daily fair-use limit. Your Usage page shows live counters and the reset date.

Can I cancel anytime?

Yes. Cancel from the Billing page at any time — your plan stays active until the end of the paid period. We ask for optional feedback but never block cancellation.

What happens to my reports after cancellation?

Nothing is deleted immediately. Your workspace moves to the Free plan: projects beyond the Free limit become read-only, monitors beyond your slots are paused, and detailed history follows the Free retention period. Aggregated score history is kept longer.
