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.
9Proxy provides reliable residential proxies with clean, fast connections, starting from just $0.015/IP and $0.68/GB. We offer exclusive advantages for affiliates, resellers, and partners, helping enhance online activities and build long-term mutual benefits.

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.
9Proxy's answer:
9Proxy's primary audience includes SEO professionals, market researchers, and data analysts who require reliable and anonymous internet access for data scraping, SERP analysis, and market research. It also caters to businesses involved in ad tech, multi-accounting, and price aggregation, providing them with the necessary tools to perform their tasks efficiently and securely.
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.
9Proxy's answer:
We are a group of professionals identifying a gap in the market for reliable, affordable, and anonymous proxy services. We then leverage our expertise in network technology and security to create a solution that addresses these needs, leading to the establishment of 9Proxy. The company has grown by focusing on customer needs, technological advancements, and quality service.
9Proxy's answer:
Our biggest customers generally include: Digital marketing agencies SEO and SEM professionals Big data analytics firms E-commerce companies Cybersecurity companies Academic and research institutions
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.
9Proxy's answer:
9Proxy stands out with over 20 million clean residential proxies, ensuring high anonymity and security for users. With competitive pricing starting from just $0.015/IP and $0.68/GB, 9Proxy delivers reliable and cost-effective proxy solutions, making it an attractive choice compared to many competitors on the market.
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.
9Proxy's answer:
9Proxy is built on a scalable cloud-native infrastructure using high-performance proxy routing technology, distributed IP management systems, and secure authentication layers. Our platform leverages modern backend frameworks and real-time traffic optimization to ensure stability, anonymity, and 99.95% uptime.
