Good morning, Mr. Krzysztof.

I understand the task: you need a monitoring bot (scraper) that will automatically check for new listings after pasting a link to a category (OLX, Allegro, Etsy) and send a notification.

Technical challenge: Services like OLX or Allegro have strong anti-bot protections. A regular script will stop working after a few hours.

My solution: I will build the bot based on Node.js + Puppeteer/Playwright. This technology simulates a real user browser.

You send the link to the bot.
…
The bot in the background "enters" the site every X minutes (using User-Agent rotation to avoid blocking).

When a new listing appears -> The bot sends you the link and photo on Telegram.

I have experience in creating bots for Telegram. I am ready to discuss which specific services are a priority to start with.

Best regards, Nazarii

Hello! I have created similar projects for OLX.PL, Allegro, and Vinted. I have a lot of experience. The script runs automatically, searches for new objects, and can immediately send data to Telegram.

Hello! I have successful experience in developing monitoring systems for OLX and other large marketplaces.

Your task is clear to me. I will implement a stable solution that will work 24/7, instantly track updates from your links, and send notifications to Telegram.

What you will receive:

Support for working with multiple platforms (OLX, Allegro, Etsy, and others).
A duplicate filtering system (notifications only for new listings).
Customization of the checking frequency to meet your needs.
… Reliable mechanisms for stable operation without blocks from the sites.

For an accurate estimate of cost and timelines, please send me a private message with the complete list of websites that need to be added to the monitoring. I look forward to collaborating!

I already have a ready example of such a bot, which can track not only the categories you choose but also a specific seller. https://freelancehunt.com/showcase/work/telegram-bot-dlya-avtomatichnogo-monitoringu-olx/2006431.html

Hello 👋

I can create a bot that checks the pages you specify (OLX, Allegro, Etsy, and other sites) and tracks the appearance of new listings. You simply add the links — the bot periodically checks the page and notifies you if something new appears.

How it will work:

the bot saves the current state of the page

with each check, it compares the changes
…
if a new listing appears — you receive a notification

you can set the frequency of checks and the format of notifications; I specialize in Telegram, and we can also add notifications via email or Viber.

I support working with multiple sites, and I can add filters or logic for specific platforms.

I can implement a Telegram bot that tracks the appearance of new listings, but I need an exact list of which platforms will be used. You add the links - the bot regularly checks them and notifies about new listings. I have such a bot for OLX.

What I can offer:
- support for multiple websites with different update logic;
- recording already found listings to avoid duplicates;
- customizable check interval;
- notifications in Telegram with a link, price, and brief information;
- the ability to easily add/remove links without code modifications.
…
I have extensive experience with similar bots and marketplace parsing. The cost and timeline are negotiable, depending on the number of websites and functionality. I am ready to discuss the details.
