LaunchLintGet Started
Built for shipped sites · CI + cron + deploy gate

Lint your site before you ship it.

LaunchLint crawls every page like a real visitor—catching broken links, console errors, accessibility violations, slow routes, and visual regressions before your launch does.

QA on autopilot

Your site,
checked before it ships.

One automated QA layer for links, errors, accessibility, and performance—designed to run in CI, cron, or on every deploy.

Broken link detection

Every page, anchor, and asset crawled on every run. Dead ends are caught before your customers find them.

Console error capture

JavaScript errors, failed requests, and 4xx/5xx responses collected from real page loads, not just static HTML.

Accessibility audit

axe-core rules on every page, with violations ranked by impact and pinned to the exact DOM node.

Performance budgets

Lighthouse-style Core Web Vitals checks that fail the build when a page gets slow, not after launch day.

Visual regression diffs

Pixel-level screenshots compared between runs so a broken hero or shifted layout never ships silently.

Scheduled monitoring

Run on every deploy, on a cron, or from CI. LaunchLint gates the release with a pass/fail report.

How it works

From URL to green check.

Three steps between you and a launch you can trust.

01

Point

Add your site URL and pick a schedule. LaunchLint crawls every route and loads each page like a real visitor.

02

Audit

Links, console errors, axe-core accessibility, Core Web Vitals, and visual diffs run in parallel across the whole site.

03

Ship (or block)

Get a ranked fix list with screenshots. Wire the pass/fail gate into CI so regressions never reach production.

Simple pricing

Catch it before launch day.

Every plan includes link, error, and accessibility checks, pass/fail reports, and alerts when something breaks.

Loved by shippers

Launch day, without the dread.

Developers and teams use LaunchLint to keep every deploy as clean as the first one.

It caught a broken checkout link 20 minutes after a redesign deploy. That one email paid for a year of LaunchLint.

The axe-core violations are ranked by impact with exact DOM nodes. Our a11y backlog went from guesswork to a checklist.

We wired the CI gate into our release workflow in ten minutes. Blocking bad deploys feels like cheating.

FAQ

Questions,
answered.

Still curious? Email hello@launchlint.dev.

Do I need to change my code to use LaunchLint?

No. Point LaunchLint at any URL and it runs externally—no SDK, no instrumentation. A CLI and GitHub Action are available if you want to gate CI.

What exactly gets checked?

Every crawl covers broken links and assets, JavaScript console errors, failed network requests, axe-core accessibility violations, Core Web Vitals performance budgets, and pixel-diff screenshots between runs.

Will it slow down my site?

LaunchLint loads pages like a single polite visitor with a unique user agent, respects rate limits, and can be scheduled off-peak. Nothing is installed on your servers.

Can it block a deploy?

Yes. The pass/fail exit code plugs into GitHub Actions, GitLab CI, Vercel deploy hooks, or any script—regressions block the release, green reports ship.

Can I change or cancel my plan?

Yes. Plans are month-to-month. You can upgrade, downgrade, or cancel from your billing portal at any time.

Ship it clean.

Never ship a broken page again.

Run your first lint in minutes and turn launch day into just another Tuesday deploy.
