Just be yourself; life is too short for pretending to be someone else

Yes — the project is Apache 2.0 licensed ( https://github.com/dgtlmoon/changedetection.io/tree/master?t... ), which permits forking and commercial use. There's also a COMMERCIAL_LICENCE.md in the repo for

Yes! Exactly this direction — the hybrid fetch is already live: plain HTTP first, Chromium if the content looks off. LLM semantic targeting is the next step, but only triggered when a selector breaks, not on every check — too expensive othe

I'm planning to add proxy rotation across different regions to help with geo-restricted content and rate limiting. Anti-bot is an arms race though — some sites just can't be monitored without solving a captcha, which isn't so

Yeah, semantic anchors are definitely the right direction — [data-testid], aria-label, or text proximity tend to survive rebuilds much better than class paths. The picker leans towards CSS right now but that's something I want to impr

The selector is stored as a CSS path and matched against the fetched HTML on each check — so as long as the element's structure and nesting stay roughly the same, minor layout changes don't usually break it. The fragile cases are

Not stupid at all — the docs were missing an RSS page, which is on me. I've just added one: https://docs.sitespy.app/docs/dashboard/rss . RSS feeds are available per watch, per tag, or across all watches from

Yes — it's a fork of changedetection.io. I went into more detail here: https://news.ycombinator.com/item?id=47349141 . The RSS link you spotted was a leftover, already fixed

Fair point, and I should have been upfront about this earlier. The backend is a fork of changedetection.io. I've built on top of it — added the browser extension workflow, element picker, billing, auth, notifications, and other things

Yeah, RSS is free on all plans — it felt like a core feature, not an upsell

You can already work around the rate-limit issue today — there's a global minimum recheck interval in Settings that spreads checks out across time. Not per-site throttling yet, but it prevents one domain from getting hit too many times

by vkuprin 6mo ago
Yeah, that was a real bug — CSS transitions on the body were blocking the thread during theme switches. I pushed a fix for it earlier today. Should be smooth now, but let me know if you still see it

Site Spy keeps snapshot history, so you can revisit older versions of a page and inspect how it changed over time, not just get the latest alert. I’d describe it more as monitoring with retained history than as a dedicated public archive, b

German laws and bureaucracy pages are exactly the kind of thing where tracking one specific part of a page is much more useful than watching the whole page. And yeah, more control over check frequency makes a lot of sense if monthly checks

Thanks, that’s a really good question. Site Spy uses a real browser flow, so it generally handles JS-rendered pages much better than simple HTML-only polling tools. In practice, the trickier cases tend to be sites with aggressive anti-bot p

Yep, urlwatch is a good one too. This category clearly has a strong self-hosted tradition. With Site Spy, what I’m trying to make much easier is the browser-first flow: pick the exact part of a page visually, then follow changes through dif

That’s a completely fair concern. Services in this category do need to earn trust over time. I built the backend to handle a fair amount of traffic, so I’m not too worried about growth on that side. My goal is definitely to keep this runnin

Yep, changedetection.io is a good project. With Site Spy, I wanted to make the browser-first workflow much easier: install the extension, connect it to the dashboard, click the exact part of the page you care about, and then follow changes
19.
by vkuprin 6mo ago
Yep, Site Spy already has push notifications, plus email and Telegram alerts. I see RSS as the open interface for people who want to plug updates into their own reader or workflow. For urgent things like visa slots or stock availability, di
