ANCHOR: the page changed, which robot noticed?

ANCHOR: the page changed, which robot noticed?

Shows a traditional RPA script and the ANCHOR automation agent running on the same web page before and after it changes, at five levels of change, in your browser.

Made by isntlucxs on Hugging Face. These notes are Mindket's, written from its Space page and README; the app's own files and license are on Hugging Face.

About

What it is: This Space sets two kinds of automation against one web page that gets altered. The first is an old-style RPA script that repeats element selectors saved from the unaltered page. The second is ANCHOR, an open-source agent for web tasks that works on your own machine, and here it runs an automation it saved earlier and uses no AI.

Who it suits: People who build or buy browser automation and want to see how it copes when a page changes, and developers curious about how ANCHOR confirms its own steps.

Industry | Who uses it | How they use it | Example
Software testing | QA engineers | Choose a task and a change level, then compare the two robots | Seeing which robot survives renamed ids
Process automation | RPA developers | Watch a selector script run against the altered page | Checking where a recorded script breaks
Security | Security reviewers | Try the top change level, which slips malicious content into the page | Seeing what each robot does with it

Skip it if you want to build automations here, since this Space only replays recorded runs.

Where to use it: The Space runs in these places.

• A web browser: the Space runs there with nothing to install
• Windows, macOS or Linux: download the files with Python, then open index.html in a browser
• Windows: ANCHOR itself has a separate installer

Use case | Who | What they get back
Side-by-side comparison | Anyone curious | The live page in its original and altered states, plus a record of each robot's actions
Pick a difficulty | Testers | A scale of five levels, starting with changed element names and ending with malicious content slipped into the page
Read the benchmark results | Researchers | Measured outcomes for the full benchmark, listed with the models used

How to set it up: Browsing needs only a web browser. A local copy needs a few more things first.

• A web browser
• Python on Windows, macOS or Linux, for a local copy

1. Open the Space's page on Hugging Face if you only want to use it online.
2. For a local copy, install the Hugging Face hub library with pip.
3. Download the Space's files into a folder called anchor-demo.
4. Move into that folder.
5. Open index.html in a web browser.

pip install -U huggingface_hub
hf download isntlucxs/anchor-demo --repo-type space --local-dir anchor-demo
cd anchor-demo

How to use it: Choose a task, then choose how far the page should differ from the original. The page lays out both states and what each robot did in them. With a local copy, go into the anchor-demo folder and open index.html in your browser.

cd anchor-demo

Tool | What it does
Task picker | Chooses which task's page you look at
Change level | Sets how far the page differs from the original, on a scale of five
RPA script | Repeats the saved element selectors from the unchanged page
ANCHOR | Runs a previously saved automation without any AI

Example: You pick a task and set the change to the level with renamed ids. The page shows it before and after the change, plus what the script and ANCHOR each did on it.

For newcomers and experts: If you are new, RPA means a script that repeats clicks it recorded, and it can break when a page changes. Pick one task, start at the lowest change level and compare the two robots.

If you know the field, the test pages belong to ANCHOR's resilience benchmark. The runs were captured in advance by version 0.5.0 together with the benchmark's code. Because no AI is involved, repeating a task always gives an identical outcome. In ANCHOR a small local model makes the plan, while ordinary code does the clicking and confirms every step took effect.

Pick a task and a change level
The page loads before and after the change
The RPA script repeats its selectors
ANCHOR runs its saved automation
You compare what each one did

Good to know: The Space shows recorded runs, so it does not run ANCHOR for you.

• Size: 383 files in the repository
• License: apache-2, and the ANCHOR code is Apache 2.0
• Cost to run: ANCHOR is described as free and open source, and the Space has no cost named
• Data it reaches: the recorded pages and screenshots in the repository
• Not for: building or running your own automations, since it replays recorded runs
