Catch regressions before release and prove repairs afterward

Give technical SEO, engineering, content, and leadership the same crawl evidence. Add build checks, owners, due dates, and automatic verification without tying the audit to one laptop.

Free plan, no credit card. The first audit was evaluated within minutes. Read only Google access. Export whenever you need it.

Large scale audit

A cloud crawler that keeps up with your website

Run it on a schedule across the property, with your team keeping an eye on the same workspace rather than having to pass around a laptop.

Up to 250,000 URLs on Scale

Crawl the complete site with JavaScript rendering, live progress counters, and fast, standard, and complete presets you control per run.

Rendered versus raw

See how much of each page survives without JavaScript, the exact loophole that hides content from search engines and AI crawlers.

Rated, beyond listed

A Health Score from 0 to 100 with thematic subscores and issues ranked by impact, template reach, and internal authority so the queue is already rank.

Ship safely

Know what a redesign will cost before it goes live

Most SEO damage occurs on the day of use. Swiss Knife SEO checks the change before your users do.

  • Comparison between staging and production for customer-owned staging
  • A migration check that identifies the pages that would be lost in a redesign and the link equity at risk
  • Field-level pagination differs between any two crawls: status, indexability, canonical content, title, meta, and main content
  • robots.txt and sitemap change monitors, checked daily, with alerts
CI Health Gate GET /api/site-check/?token=...&site=12 { "health_score": 74, "pass": true } Build in progress: Condition stable, no new high severity issuePASS Next PR adds a noindex to 300 pagesFAIL The pipeline stops it before it reaches production
Built for developers

An API and a build gate on each plan

Treat SEO regressions like any other failed test. The tools are integrated into the pipeline that you are already running.

  • A read-only, per-tenant REST API for sites, crawls, issues, and link data
  • A CI health endpoint that returns the health score, the number of high severity issues, and a pass flag
  • Fail a build if the score drops or a new high-severity issue occurs before shipping
  • Token authenticated, where tokens are only stored as hash digests
rank and submit

Corrections that reach the right person and are reviewed

Connect your Google data to sort the queue based on actual traffic, then route the work to where your team lives.

Traffic-conscious priorities

Connect GA4 and Search Console, both read-only, and issues will be weighted by the pages that actually get clicks, not the raw number.

Owners, data and SLAs

The Fix Workspace assigns acceptance criteria to each result and is automatically marked as verified during the next crawl.

In your tools

Create tasks in Jira, ClickUp, Asana and Trello, send rich cards to Slack and Microsoft Teams or trigger a webhook.

Recommended for most internal teams: Pro for the API, JavaScript rendering and the Google join, or Growth when you add AI visibility and more websites. Compare plans.
Questions

What technical teams ask first

Is JavaScript rendered?
Yes, from the Pro plan. Each scanned page is opened in a real cloud browser and the raw HTML code is compared with the rendered result, allowing you to see the content that exists only after scripts are executed, which is important for Google and for AI crawlers that never run JavaScript.
Is there an API and a CI gate?
Yes. A read-only, per-tenant REST API covers sites, crawls, issues, and link data, and a CI health endpoint returns the health score, the number of high-severity issues, and a pass flag so a pipeline can fail a build before shipping a regression. Both are available on every plan.
How does the fix check work?
In the Fix Workspace, assign a finding with an owner, due date, and acceptance criteria. During the next crawl, the issue will be checked again and marked as confirmed. The All Issues report shows “new” and “fixed” per type, closing the loop without manual review.
