Sightline for agencies and web studios

Catch what's broken on a client site before the client does.

For the sites you build and run for clients. Sightline reads a client's public pages and reports broken links and forms, unclear or contradictory claims, pages that fail on a phone, and gaps in basic web security hygiene. Every finding comes with its evidence and lands on a to-do list for the page it belongs to. It is not a prospecting tool: it never runs on a site you are pitching.

What Sightline checks

Four things a visitor runs into, each with the evidence behind it.

Every finding carries the exact text, link or response it came from, so nobody has to take it on faith, and it lands on a to-do list for the page it belongs to.

Broken links and forms

Links that lead nowhere, buttons that do nothing, and forms a visitor cannot get through. Each one is pinned to the page and the element where it happens.

Unclear or contradictory claims

A price on one page and a different one on another, a feature promised in the hero and missing further down, copy a first-time visitor cannot follow.

Pages that fail on a phone

Layouts that scroll sideways, controls too small to tap, content that disappears on a narrow screen.

Basic web security hygiene

Response headers, cookie flags and certificate setup, read from what the site already returns to any visitor.

How it works

From a client domain to a fix list, then a re-check.

  1. Add a client's domain

    Only a site you build or run for a client who has agreed to the check. The domain is verified with one DNS record, added by whoever manages the client's DNS with the client's say-so.

  2. Run Sightline

    It reads the public pages across the site, and you can watch it work through them page by page while it runs.

  3. Work the per-page to-do list

    Each page closes with its own list of fixes in rank order, with the severity and a rough effort for each, ready to drop into your tracker.

  4. Re-check after changes

    Run it again when the fixes ship, or turn on the weekly re-scan for that domain, so the next report shows what is still open.

What it never does

  • It reads public pages only, the way a visitor would.
  • It does not log in to anything.
  • It changes nothing on the site: no content edited, no account touched.
  • It only runs on a domain whose owner has verified it with a DNS record, never on a site someone else picked.
  • It is a read of what a visitor meets, not an auditor's sign-off, and it never tries to break in.

Plans

Sightline is a monthly subscription for each client domain, and a single report costs the same as one month of its plan. Accounts are by invitation for now. See the plans and what each includes →
