Does Lyro see content that only appears after JavaScript runs?

Yes. Fetch HTML Content returns the full contents of a page including dynamically generated markup, and Scrape Webpage Content Using CSS Selectors navigates to the URL and waits for the page to parse and execute JavaScript before returning the selected elements as structured JSON.

What happens when a site blocks automated browsers?

Unblock Protected Content is the action for that case. It is built to get past CAPTCHA and bot detection and return the protected page's HTML, and it takes waitFor, timeout, and stealth mode parameters so a stubborn page can be given more room before Lyro gives up on it.

Can Lyro run our own Puppeteer code rather than a fixed action?

Yes. Execute Custom Function runs a custom Puppeteer script through an HTTP request on Browserless infrastructure, so there is no browser fleet to maintain. Download File Using Puppeteer Script goes further: it opens a blank page, creates a fresh download directory, injects your code, and returns whatever Chromium downloaded.

How is this different from a Browserless step in Zapier or Make?

Those run one preset call when a trigger fires. Lyro decides mid-conversation which Browserless action fits - scrape a selector, screenshot the page, fall back to the unblock endpoint when the first attempt is refused - and can chain several of them before it replies.

How businesses use Browserless + Lyro

Each card is one request a support team gets, and the Browserless actions Lyro runs to close it.

Read a live page to answer a question
Lyro loads the page, waits for its JavaScript to run, and pulls back either the complete HTML or just the elements named by CSS selector, so an answer comes from what the page shows right now.
Fetch HTML ContentScrape With CSS SelectorsTake Screenshot
Turn a web page into a document
Lyro renders a URL to PDF with the format, filename, and waitUntil settings the job needs, or captures a full-page PNG or JPEG, giving a customer something they can keep rather than a link that may change.
Generate PDF From WebpageTake ScreenshotFetch HTML Content
Reach a page that blocks ordinary bots
For sites behind CAPTCHA or bot detection, Lyro requests the content through the unblock endpoint with stealth mode and its own waitFor and timeout settings, then reads the returned HTML as normal.
Unblock Protected ContentFetch HTML ContentScrape With CSS Selectors
Run a scripted browser task end to end
Lyro executes a custom Puppeteer script over HTTP for multi-step flows, and where the script triggers a download, collects the files Chromium saved and returns them with the right content type.

How it works

Get started in 3 steps

Connect once, then just ask. There is no workflow builder to learn and nothing to maintain — Lyro reads the Browserless actions it has and picks the ones a request needs.

01
Connect Browserless
Authorize the Browserless account your team already uses — one consent screen, no API keys, no mapping tables. Lyro can only do what you granted that account, and you can disconnect it at any time.
02
Tell your agent what you need
Describe the job the way you would hand it to a teammate. Lyro maps it to the Browserless actions that close it and chains as many as the request needs.
03
Watch it work
The agent runs the actions inside the conversation the customer is already in, so nobody copies data between tabs and your team can take over at any point.
