Apify is a JavaScript & Node.js based data extraction tool for websites that crawls lists of URLs and automates workflows on the web. With Apify you can manage and automatically scale a pool of headless Chrome / Puppeteer instances, maintain queues of URLs to crawl, store crawling results locally or in the cloud, rotate proxies and much more.
Verid is an API-first change monitoring platform for developers and operators. Point it at any URL, define what to extract with CSS selectors, XPath, JSONPath, regex, or AI and Verid checks it on your schedule, down to every 5 minutes. Unlike visual-diff tools that alert on any pixel change, Verid tracks the fields you care about. Set predicates like "notify me when price drops more than 5%" or "when stock changes from out to in," and ignore everything else. When a change matches, Verid delivers it as structured JSON through signed webhooks with automatic retries, a dead-letter queue, and one-click replay — plus email, Slack, and Discord. Every paid plan includes the full REST API, all extraction methods, and all delivery channels; higher tiers add capacity, not held-back features. Use it to track competitor prices, job listings, product stock, regulatory pages, or any page that matters — via a simple URL-paste form or config-as-code. Start free with 5 monitors, no credit card required.

Verid.dev's answer:
Verid was born from a gap that I had faced while working on another product of mine that is: existing change-monitoring tools are visual-diff first and built for non-technical users, while scraping APIs are stateless one-shot tools with no scheduling or diffing. Developers who wanted "tell me when this specific field changes, via a signed webhook" had to glue together cron jobs, scrapers, and notification code themselves. Verid packages that whole pipeline, scheduled checks, structured extraction, field-level diffing, and reliable delivery into one product.
Verid.dev's answer:
Verid is extraction-first, not visual-diff first. Instead of alerting when a page looks different, it extracts the exact fields you care about — with CSS, XPath, JSONPath, regex, or AI and fires only when your condition is met, like "price dropped more than 5%" or "stock changed from out to in." Changes arrive as structured JSON through signed webhooks with automatic retries, a dead-letter queue, and replay. No other change-monitoring tool combines field-level alert conditions with developer-grade webhook delivery.
Verid.dev's answer:
Three reasons. First, structured output: you get JSON like {"price": 49.99, "stock": "in_stock"}, not a screenshot or an AI summary you have to parse. Second, no feature gating: every paid plan includes the full REST API, signed webhooks, Slack/Discord delivery, and all extraction methods higher tiers add capacity, not previously-withheld features, so there's no pricing surprise when you need API access or a second delivery channel. Third, reliable delivery: webhooks are HMAC-signed, retried with exponential backoff, and replayable from the dashboard.
Verid.dev's answer:
Developers and technical teams who want change monitoring as infrastructure, an API, webhooks, and config-as-code. Second, operators who don't code: indie hackers, e-commerce founders, marketers, and researchers tracking competitor prices, job listings, stock levels, or regulatory pages through a simple URL-paste form and a templates gallery.
Verid.dev's answer:
TypeScript end to end. Next.js and React power the dashboard and REST API, a Node.js worker fleet handles scheduled checks with BullMQ job queues on Redis, Playwright drives real headless-browser rendering for JavaScript-heavy pages, and PostgreSQL stores monitors, run history, and diffs.

The first network smoke labeled https://apify.com/ inconclusive even though the page was healthy. The response carried a Content Security Policy header larger than aiohttp's default 8 KB field limit. The client failed while parsing headers, before I saw the 200. - Source: dev.to / 1 day ago
Native @apify scheduling, dataset exports (CSV/JSON), webhooks, and it's callable by AI agents via Apify MCP. - Source: dev.to / 13 days ago
That runs News Scraper on Apify, which is the same forty lines plus the parts that are Tedious rather than hard: both feeds, the nested publisher element, the date Normalisation, and deduplication. - Source: dev.to / about 1 month ago
That runs an Apify Actor I maintain, Domain Scraper, because the Tedious parts are the RDAP bootstrap, the vcard unpacking and the provider Fingerprinting rather than the HTTP call. If you would rather do it yourself, Https://rdap.org/domain/ is the whole API and it needs no key. - Source: dev.to / about 1 month ago
Data collection: Apify actors, one per source, that scrape the open-data endpoints and normalize them. Quebec RBQ ships a daily bulk CSV (inside a 10.8 MB zip, ~924k rows that dedupe to ~54k active licences). Ontario HCRA has no bulk file — it's an internal JSON API behind the public registry. - Source: dev.to / about 2 months ago
