NerdyData has no write-up on Specifiction yet; its figures are above.

SiteGauge monitors web pages and alerts users when a check confirms a meaningful change. It can watch a page, part of a page, a full sitemap, or pages behind a login. AI summaries describe what changed and why it may matter, while before-and-after screenshots support visual comparison. SiteGauge can also extract pricing information to track plan changes, new tiers, and discount wording. Alerts can go to Slack, Teams, Discord, Telegram, Google Sheets, SMS, webhooks, Zapier, or RSS; an API and MCP are also available. The Free plan provides five monitors and 150 checks per month, with daily checks and 30-day change history. Paid plans start at $19.20/mo billed annually and begin with a seven-day free trial. If a plan’s checks run out, its monitors pause until the next calendar month’s allowance resets, and unused checks do not roll over. The browser extension is free, works with Chrome and Edge, and uses the same plan allowances. SiteGauge says its traffic uses TLS and reused secrets are encrypted at rest with AES-256-GCM. It does not currently hold a SOC 2 report or ISO 27001 certification.
