Edit: it looks like you hit an edge case that I didn't see in testing. Happy to explain more, but it was skipping the extraction due to some pre-processing that craigslist was failing when it shouldn't have.
Would love if you want to try the tool again, but completely understand if not :)
It’s an extraction pattern for a certain site, so you can reuse it. Think a pattern to extract all forum posts - then using that on different pages with the same format. Like show new, show, new posts on HN.
Would be curious to try it out on your sites if you want to shoot me a few over - I can share my email.
It does use a browser to find dynamic content but does not afterwards.
Definitely going to give this more thought though, thank you for the comment
Bot protection - this is handled in a few ways, the basic form bypasses most bot protections and that’s what you can use on the site today. For tougher sites, it solves the bot protections (think datadome, Akamai, incapsula).
The consistency part is ongoing, but it’s possible to check the diffs and content extractions and notice if something has changed and “reindex” the site.
100k URLs is a lot! It could support that, but the initial indexing would be heavy. It’s fairly resource efficient (no browsers). For scale, it’s doing about 40k/scrapes a day right now.
Appreciate the comments, happy to dive deeper into the implantation and I agree with everything you’ve said. Still iterating and trying to improve it.
1. Paste a URL in, describe what you want
2. Define an interval to monitor
3. Get real time webhooks of any changes in JSON
Lots of customers are using this across different domains to get consistent, repeatable JSON out of sites and monitor changes.
Supports API + HTML extraction, never write a scraper again!
I didn’t like the current tools, so I built meter. It syncs a website and fires webhooks whenever content changes.
To start, you just need to plug a site URL in. It will find any APIs or fallback to HTML if needed for the data.
