@FetchFox

Working great as of 30/11/2024. Let me tell you why I'm so happy about this, because I was desperate: - Firecrawl.dev? Inconsistent API documentation. Apify scrapers? Couldn't work on my target URL. - I spent $150 over 4-5 OTHER tools before finding this one, which is free to use locally right now. Wow. I'm dumb. - My target URL was a broken site, with 500 javascript errors, content violations, bad cookies, etc. - Not a single scraper worked that I tried, except for this one. So yeah, I'd say I'm pretty happy

AVOID AT ALL COSTS. Amateur hour if I ever saw it: they change their entire API endpoints on a whim on the SAME VERSION, breaking all of the work you've done to integrate with them (thousands of $), then tell you you're not an $5k / month Enterprise customer and they don't really support their self serve product so...tough luck buddy. I was one of their first customers and have been using them for over a year and a half only to wake up one day to customer complaints because our integration had broken and be told they basically don't care about. After I reached out to their team, it became clear that they had simply changed their entire API from one day to the next on the same version, with no notice and a documentation that doesn't reflect the changes they made. Literally everything is broken in one way or another: the UI fails to save changes every other try, the API has three different versions in use at the same time, some endpoints use v3 others use v4, similar payload responses don't even reply with the same structure for the data, the documentation is completely out of sync with the actual endpoints, the webhooks trigger 3 times in a row and on and on and on... Somehow they have several engineers, yet no-one there actually knows how to fix your problem. I've been a customer for over a year and a half and after breaking my entire integration, they just told me to go take my business elsewhere because they couldn't support their OWN breaking changes! Oh and by the way, it took a week of back and forth and trying to fix my integration and work with their broken documentation to tell me this. Total insanity. I couldn't ever imagine being an Enterprise customer with these people, their whole product is built on a shoestring and they have absolutely no respect whatsoever for their customers.

It converts raw HTML content into markdown - a simpler, more structured form that offers only the relevant information. It replaces CSS selectors with short element references. It takes on the task of parsing raw HTML to tangible insights, thereby reducing the burden on agents to sift through vast loads of unstructured and irrelevant data.

What is the purpose of the 'stability signal' feature in Browserbeam?

The 'stability signal' feature in Browserbeam serves as a notifier for when the page has fully loaded and is ready for interaction. This feature eliminates the need to guess wait times or waste resources on premature reads. When the stability signal is received, the user's agent can be confident that the entire content of the webpage has been loaded and is ready for analysis or interaction.

What is the difference between Browserbeam and other browser APIs like Browserless, Browserbase, and Steel?

Browserbeam sets itself apart from other browser APIs like Browserless, Browserbase, and Steel by primarily focusing on dealing with the data that Low-level Language Models (LLMs) actually need. While the mentioned browser APIs handle infrastructure aspects, Browserbeam solves the part about making the data workable for LLMs. It doesn't just offer raw HTML like these APIs; instead, it provides markdown content, short element references, a stability signal, change diffs after every action, and handles cookies banners, popups, and CAPTCHAs automatically among other features.

How does Browserbeam automatically handle cookie banners, popups, and CAPTCHAs?

Browserbeam handles cookie banners, popups, and CAPTCHAs automatically by detecting and dismissing these elements without requiring any direct action from the user or the AI agent. This allows the AI agent to focus solely on its primary task without being interrupted or requiring additional actions to manually dismiss these elements.

What are the benefits of the automatic form filling feature in Browserbeam?

The automatic form filling feature in Browserbeam reduces the complexity of dealing with forms on a page. By providing structured forms with field references, filling out a login page becomes as simple as one API call. This means the user's agent doesn't have to manually find, organize, and interact with every individual field on a form. Instead, it can deal with the form as a single, cohesive unit.

How does the AI-powered extraction in Browserbeam work?

In Browserbeam, AI-powered extraction works by caching selectors per domain. The user describes what they want in plain English (e.g., 'the product title', 'the price including currency'), and the engine identifies the correct selector. After the first scrape, which costs AI tokens, every subsequent scrape is free as the engine caches the selector for each domain. This makes future scrapes more efficient and free of added costs.

What is the role of the Browserbeam's REST API?

The role of Browserbeam's REST API is to offer user-friendly and effective browser control for AI agents and web automation. The API receives JSON and returns structured JSON back. This enables the user's agent to interact with the webpage using simple commands, instructions, and data formats, which streamline the process of gathering data, interacting with webpages, and achieving automation goals.

What kind of content does Browserbeam return?

Browserbeam returns Markdown content, which is a simple, text-based data format that carries all the essential information without the unnecessary clutter of raw HTML. It provides short and stable element references in place of long and potentially fragile CSS selectors, alongside a diff after every action showing what has changed on the page. This ensures the AI agent receives data that is designed to be minimal yet informative.

Which programming languages does Browserbeam's official SDKs support?

Browserbeam's official SDKs support three widely used programming languages: Python, TypeScript, and Ruby. Moreover, there's an MCP server for Cursor, Claude Desktop, and Windsurf, widening its accessibility and ease of use.

What is the Browserbeam trial offer?

Browserbeam offers a free trial with 5,000 credits. This trial does not require a credit card for activation and gives potential users the opportunity to explore and understand the capabilities of Browserbeam without any upfront financial commitment.

How does Browserbeam reduce the amount of Puppeteer code needed?

Browserbeam can replace approximately 25 lines of Puppeteer code with just one POST request. By handling tasks such as stability detection, diff tracking, automatic handling of cookie banners, pop-ups, and CAPTCHAs, along with structured data extraction and form filling within its REST API, Browserbeam reduces the need for complex code and simplifies the overall process of browser automation.

What does the 'diff after every action' feature in Browserbeam do?

'Diff after every action' is a feature in Browserbeam that provides an updated state of the page after every user action. It notifies the user or AI agent about what has changed on the page, including new elements added, old elements removed, elements modified, etc. This allows the agent to always be aware of the current state of the webpage, without having to re-parse the entire page.

What is 'element refs' in Browserbeam and how does it work?

'Element refs' in Browserbeam are shortened references to webpage elements, provided in place of traditional CSS selectors. They offer a stable, convenient way for users or AI agents to interact with the elements on a page. The 'refs' are shorter to work with, less prone to breaking due to website design changes, and help simplify the interaction with webpage elements.

What benefits does the 'scope' feature offer in Browserbeam?

The 'scope' feature in Browserbeam allows users to define the specific section of the webpage they want to interact with or extract data from, thus reducing unnecessary bloat and focusing on the most relevant elements. This results in improved efficiency as the AI agent processes only the scoped, essential data, and avoids handling irrelevant information.

What advantages does Browserbeam's AI-based Data Extraction provide?

Browserbeam's AI-based Data Extraction provides valuable advantages such as eliminating the need for maintaining a CSS map per site, dealing with fragile selectors, or repetitive scrapes. The AI engine in Browserbeam understands what the user wants based on descriptions provided in plain English and finds the right selectors. These selectors are then cached per domain to allow free reuse in future scrapes, thus saving resources.

How does Browserbeam's form filling simulation work?

Browserbeam's form filling simulation works by providing structured forms with field references. This allows filling out a form, for instance, a login page, to become as simple as one API call. This streamlines the process greatly compared to manually identifying every individual field on a form, filling it, and submitting it one by one.

Why does Browserbeam use Markdown content instead of raw HTML?

Browserbeam uses Markdown content instead of raw HTML to offer structured data in an efficient, easy-to-parse format. This lightweight markup language simplifies the data, focusing only on the relevant information needed for decision-making or action. This dramatically reduces the bloat associated with raw HTML and speeds up processing times, thereby contributing significantly to the efficiency of the AI agent's operations.

What is the purpose of the 'Automatic Cache Management' in Browserbeam?

Automatic Cache Management in Browserbeam takes care of storing and reusing correctly identified selectors. Once the AI engine finds the right selector for a user's description, it caches that selector per domain. This means that for every subsequent scrape, no AI tokens are used, making future scrapes free and improving the efficiency of the browsing process.

How does Browserbeam detect and handle webpage changes?

Browserbeam detects and handles webpage changes through its 'diff tracking' feature. After each action, Browserbeam returns a 'diff' - a summary of what has changed on the page. This includes elements added, removed or modified. This allows the AI agent to stay informed about the present state of the webpage without having to re-parse the entire page and identify the changes itself.
