Skip Verid if you need full-page screenshot change detection without field-level extraction, or if you need real-time monitoring faster than 5-minute intervals, or if you're looking for general-purpose scraping of large volumes of data.
LLM extractions are metered and capped per month (50 on Free, 250 on Lite, 500 on Starter, 5,000 on Pro, 25,000 on Scale) — if you exceed the cap, extractions pause until the cycle resets, which can stall your monitors.
Verid's pricing fits developers and small teams who need a free tier with real capabilities (5 monitors, daily checks, 50 LLM extractions) and scale to $9/mo Lite for side projects. Compared to Firecrawl, which charges per scrape and requires building your own monitoring loop, Verid's per-plan capacity model is simpler for monitoring workloads. For enterprise teams needing 5-minute intervals and 1,500 monitors, Scale at $149/mo is competitive vs. building in-house or using Apify Actors with

Google SERP monitors now render the results page and report a block instead of storing it
Fixed Google search monitoring where plain-HTTP fetches returned a 200 with no results; now Google URLs skip plain HTTP, render in browser, wait for the results container, and correctly grade rejections, making failures fast and honest.
Playground Compare two URLs now compares content profiles, not markup
Compare mode no longer diffs raw HTML; it compares title, meta, headings, prices, CTAs, and word count field-by-field for two different sites, making cross-site comparisons more meaningful.

About Verid
Verid is a developer-first API that monitors web pages and APIs for meaningful changes, extracting the exact fields you care about—prices, versions, stock status—and firing a webhook only when a predicate you define is true. Built for developers, DevOps engineers, and data analysts, it eliminates the noise of screenshot alerts and the fragility of DIY scrapers by closing the entire monitoring loop: fetch, extract, diff, predicate, and deliver. Under the hood, Verid runs a five-stage pipeline. It fetches with static HTTP, auto-escalating to a headless browser or residential proxy when a site resists. Extraction supports six methods: CSS selectors, XPath, JSONPath, regex, full-page hashing, and LLM-powered extraction in plain English. Every run produces typed fields, and Verid compares them against the last successful run to deliver field-level diffs—the before/after values, not a vague "page changed" notification. Predicate-based alerting is the core differentiator. With nine predicate types and AND/OR composites, you can fire on a 10% price drop, a semver bump, or a stock return. When a rule fires, Verid delivers the diff as an HMAC-signed webhook (Stripe-compatible), Slack message, Discord notification, or email, with 6 retries using exponential backoff and a dead-letter queue. Recent updates also fixed Google SERP monitoring (now renders the page and waits for results) and improved the Playground's Compare mode to compare content profiles rather than raw HTML. Verid is a freemium service with a permanent free tier—5 monitors, daily checks, 50 LLM extractions/month—and paid plans from $9/month. Unlike screenshot-only tools that spam on cookie banners or raw scraping APIs that leave you to build the loop, Verid closes the loop entirely: structured extraction, durable state, field-level diff, and predicate-driven delivery in one package.
Behind the Verdict
We've seen too many monitoring tools that either spam you with full-page screenshots or hand you a half-built scraper. Verid takes a different route: it extracts the specific field you care about, diffs it against the last run, and only alerts when your predicate passes. That means you get woken up for a price drop, not for a cookie banner. This is a tool for developers who want quiet, reliable signal. When should you pick Verid? If you're tracking competitor prices, version releases, or API contract drift, it's an ideal fit. The extraction methods—CSS, XPath, JSONPath, regex, full-page hash, and LLM—cover both structured APIs and messy, bot-protected pages. The three-layer fetch (static → headless → proxy) handles real-world sites better than most DIY setups, and the HMAC-signed webhooks with 6 retries and a dead-letter queue mean you won't miss a delivery. Where it might not fit: if you need full-page visual diffs without field-level extraction, Verid's region-scoped pixel diff (on paid plans) is narrower. Non-technical users may find the API-first approach intimidating compared to no-code tools with dashboards. And real-time monitoring faster than 5 minutes isn't available—the Scale tier tops out at 5-minute intervals. Compared to Firecrawl, which is a scraping API with scheduling, Verid focuses on the monitoring loop—state, diff, and alerting—so you don't build that yourself. It's also a viable alternative to Google Alerts for structured change detection. If you're already using webhooks, the signed delivery is a standout. One practical caveat: metered usage like LLM extractions and proxy bandwidth can add up on lower tiers, and hitting a limit pauses usage rather than billing overage. That's actually good news if you're budget-conscious—you'll never get a

Real-world workflow fit
Concrete scenarios for the personas Verid actually fits — and what changes day-one when you adopt it.
You want to be notified when a new version of a GitHub repo is released, but only when the version is a stable release (not a pre-release). You create a monitor on the GitHub releases API, extract the tag name with JSONPath, and set a predicate with a regex to match a semver pattern. When a new stable version appears, Verid sends an HMAC-signed webhook to your CI system.
Outcome: You get a targeted alert only when a stable release is published, with the before/after version numbers, and you can trigger an automated pipeline without polling GitHub or writing a custom scheduler.
You maintain a critical REST API and want to catch breaking changes before they hit production. You set up a monitor on the API's swagger.json, use JSONPath to extract the schema definitions, and apply a composite predicate that fires when a required field is removed or a type changes. The alert goes to a Slack channel.
Outcome: You receive a field-level diff of the schema change with the before/after values, allowing you to address breaking changes immediately, as described in the 'API Contract Monitoring' blog post.
You need to track a competitor's product page and get an alert when the price drops by more than 10%. You use CSS selectors to extract the price and availability, and set a composite predicate that requires both a price drop and an 'in stock' status. The alert goes to email.
Outcome: You receive a concise email notification with the old and new price values, allowing you to quickly adjust your own pricing strategy without checking the page manually.
Use Cases
- Monitor a competitor's pricing page and receive a webhook when any price drops by more than 10%.
- Track the latest release version of an open-source project on GitHub and get notified on each update.
- Watch an e-commerce product's stock status and trigger an alert when out-of-stock becomes available.
- Scrape a job listings page and filter for new postings matching a specific regex pattern.
- Check a REST API endpoint for changes in a key field (e.g., USD/ETH rate) and forward to Slack.
- Automate monitoring of a software changelog page using LLM extraction to detect new version announcements.
- Monitor API contract drift by watching for schema changes in a JSON response.
- Feed AI agents with fresh web data via webhooks on change, avoiding full re-scrapes.
Limitations
- Verid's plans have capacity limits: Free (5 monitors, daily minimum interval, 14-day history, 50 LLM extractions/month), Lite (25 monitors, hourly checks, 90-day history, 250 LLM extractions/month), Starter (50 monitors, hourly checks, 180-day history, 500 LLM extractions, 50 MB proxy bandwidth), Pro (250 monitors, 15-minute checks, 365-day history, 5,000 LLM extractions, 500 MB proxy bandwidth), and Scale (1,500 monitors, 5-minute checks, 2-year history, 25,000 LLM extractions, 5 GB proxy bandwidth).
- Residential proxy bandwidth is metered and only included from Starter up; manual runs per day are tiered.
- All plans include the full feature set, but limits are enforced server-side.

Setup time & first value
How long it actually takes to get something useful out of Verid — broken out by persona, not the marketing-page minute.
For a simple monitor using CSS selectors or JSONPath, most users can create one and see their first diff within 5 minutes. Setting up predicates and webhooks adds a few more minutes. The Playground lets you test extraction on a live URL without signing up, so you can validate your selectors before creating a monitor. Advanced setups like LLM extraction or Google SERP monitoring may take 15–30
Switching to or from Verid
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From DIY scrapers: Replace fragile fetch-schedule-diff-alert scripts with Verid's pipeline by defining extractors and predicates; existing JSON data can be imported via API or manual setup.
- →From Apify Actors: If you use Apify for scheduled monitoring, you can recreate the same logic with Verid's monitoring API, using webhooks instead of Actors' output—see the comparison blog post for guidance.
- →From Firecrawl: Firecrawl provides scraping and scheduling, but you still need to build diffing and alerting; Verid's monitoring loop replaces that glue code, and you can port your selectors.
- ↗To in-house monitoring: Export your monitor configurations (URLs, extractors, predicates) and replicate them with custom scripts or open-source tools like Changedetection.io.
