What’s new on 5sec.io

Every change you can see or use: new features, improvements and fixes. Newest first.

October 2026

  1. Improved

    All your past tests on the homepage

    Signed in, the list of your recent tests now ends with a Show more button. Click it to load older tests, all the way back to your first one.

  2. New

    Short share links with a preview card

    Every result now has a short link: 5sec.io/r/ followed by the test id. Paste it in LinkedIn, X, WhatsApp or Slack and the preview shows your score and your hero section.

  3. Improved

    A smaller cookie banner

    The cookie choice now sits in a slim bar at the bottom of the screen. It no longer covers the page.

  4. New

    Guides

    Short, practical guides on landing pages and the first five seconds on a website. In English, Dutch and French. Read the guides →

  5. Improved

    See what the AI saw

    Your result now shows a screenshot of the part of your page the AI graded: everything above the fold.

  6. Fixed

    Language switch on shared results

    Switching language on a shared result now keeps you on the same result.

  7. New

    AI agent view

    More people ask ChatGPT, Perplexity or Google’s AI to find and compare products for them. Those agents don’t see your design. They read the text, the page code and the metadata.

    The AI agent view reads your page the way they do and checks 8 points. You get a second score next to the human one, with a fix for every fail. Tick the box under the URL field when you start a test. It costs 1 credit per test. Run a test →

  8. New

    5sec.io in Dutch and French

    The whole website is now in English, Dutch and French. Pick your language at the top of every page.

  9. New

    About page

    Who is behind 5sec.io, which parts are fully AI and how our review team checks every audit. Meet the team →

September 2026

  1. New

    Chrome extension

    Run the five-second test on any page you visit, straight from your browser. Free in the Chrome Web Store. Get the extension →

  2. Improved

    The Above the Fold Audit

    Our €249 audit has a new name that says what it covers: the Above the Fold Audit. Same review team, same report. See the audit →

  3. Fixed

    Steadier scores

    Two scoring rules contradicted each other. We fixed both, so the same page gets the same verdict more often.

  4. Improved

    Your cookie choice comes first

    Analytics now load only after you accept cookies. Change your choice at any time under Cookie settings at the bottom of every page.
