Everything in one platform

All the tools to monitor
any URL, any way.

Six extraction methods. Smart diff predicates. Visual screenshot diffs. Multi-channel delivery. A full REST API. No infrastructure to manage.

Extraction

Get the exact data you need

Six extraction methods

CSS selectors, XPath, JSONPath, regex, full-page hashing, and LLM-powered extraction. Each method is built for a specific kind of source - structured HTML, dynamic JSON APIs, or unstructured text.

Explore six extraction methods →
  • CSS selectors for structured HTML pages
  • XPath for complex document traversal
  • JSONPath for REST API responses
  • Regex for pattern matching on text
  • Full-page normalized snapshot
  • LLM extraction with plain-English instructions

Predicates

Fire only when it actually matters

Smart change detection

Verid doesn't just ask "did anything change?" You define exactly when a change is worth a notification - percentage drops, absolute thresholds, regex matches, or complex AND/OR combinations.

Explore smart change detection →
  • Trigger on any field change
  • Percentage-based thresholds (up or down)
  • Absolute value thresholds
  • Regex pattern matching
  • Field equality checks
  • Composite AND/OR conditions

Visual

See changes the way your eyes do

Visual screenshot diff

A monitor type of its own: paste a URL, screenshot the page on every check, and compare it pixel by pixel. Scope the comparison to a region, ignore noisy elements, and alert only past your change threshold - no selectors needed.

Explore visual screenshot diff →
  • Pixel-by-pixel screenshot comparison
  • Region scoping - watch just a section
  • Ignore selectors for ads and timestamps
  • Change threshold: 1%, 5%, 10%, or custom
  • Slider, side-by-side, and diff overlay views
  • Before / after / diff images in every alert

Delivery

Get notified wherever you work

Multi-channel delivery

Webhooks with HMAC-SHA256 signing (Stripe-compatible format), Slack, Discord, and email. Failed deliveries retry automatically up to 6 times with exponential backoff.

Explore multi-channel delivery →
  • Signed webhooks - same format as Stripe
  • Slack workspace notifications
  • Discord channel notifications
  • Email notifications with reliable deliverability
  • 6 automatic retry attempts
  • Full delivery log with response details

Full REST API & SDK

Every action in the dashboard is available via REST API. OpenAPI 3.1 spec included. Official Node.js SDK published on npm. API keys with per-key scope control.

  • OpenAPI 3.1 spec at /docs
  • Official Node.js SDK
  • Bearer token authentication
  • Per-key scope control (read/write)
  • Paginated list endpoints
  • Webhook signing verification utilities

Fetch strategy

Three-layer fetching, picked automatically.

Verid escalates through three fetch strategies until extraction succeeds. No configuration needed.

1

Native HTTP

Fast, lightweight. Works for most APIs, JSON feeds, and simple HTML pages. No overhead.

2

Headless browser

Renders JavaScript-heavy SPAs and bypasses basic bot detection with a stealth-enabled headless browser.

3

Residential proxy

Residential proxy network paired with a stealth browser for sites with aggressive anti-bot measures.

Templates

Ready-made monitor configs.

Start in seconds with pre-built configs for the most common use cases - pick one in the dashboard and tweak the fields.
