SiteGauge vs ChangeTower

It depends on what you weigh. ChangeTower may carry a lower headline price, while SiteGauge bundles AI change categorisation, tamper-evident audit evidence and unlimited free viewer seats into its paid plans. If you would otherwise pay per seat or bolt on compliance tooling, SiteGauge is often better value despite a higher sticker price. The pricing tables above break down each tier.

SiteGauge reliably catches content and visual changes, with a four-stage pipeline, residential rendering for bot-protected (Cloudflare and Akamai) sites, and multi-viewport desktop and mobile capture, so it tends to catch changes on pages that block ordinary monitors. For ChangeTower's side, the feature table and scorecard above show exactly what it detects, straight from our verified research.

Both monitor websites for visual, content, and HTML changes and keep a history. ChangeTower emphasizes affordable archiving, an iOS app, and broad Zapier-based automation, while SiteGauge adds AI change summaries with categorization and importance scoring, residential rendering for bot-protected sites, native Slack/Teams/webhook plus an API, and tamper-evident audit evidence.

SiteGauge is generally better for competitor monitoring because its AI categorizes changes (pricing, messaging, product, SEO) and scores their importance, so you see what matters without manually triaging raw diffs. ChangeTower reliably captures the changes and archives them, but leaves prioritization to you.

Yes. ChangeTower offers a free plan that monitors 3 pages with daily checks and 30-day history. SiteGauge also has a free plan (5 monitors, 150 checks, daily checks, 30-day history).

ChangeTower's paid plans are Lite $12/mo (25 pages), Essential $36/mo (100 pages, hourly), and Business $78/mo (200 pages, 20-minute checks, 6-month history), plus custom Enterprise pricing. Pricing is based on the number of monitored pages rather than check volume.

At the entry level, yes, ChangeTower's $12 Lite and $36 Essential undercut SiteGauge's $24 Standard and $99 Pro on headline price. However, SiteGauge prices by check volume and includes AI analysis, native integrations, and audit evidence, so the better value depends on whether you need those capabilities.

ChangeTower markets AI-powered monitoring and AI summaries, but the depth, such as importance scoring and structured change categorization, is not clearly documented. SiteGauge provides AI summaries that categorize changes and assign an importance score natively.

Yes. ChangeTower has a native Zapier app whose 'New Notification' trigger connects to 30+ apps including Slack, Microsoft Teams, Discord, Telegram, and SMS, and it supports webhooks. Many of these channels are routed through Zapier rather than being native, whereas SiteGauge offers native Slack, Teams, Discord, Telegram, Google Chat, SMS and webhook channels on Standard ($24/mo) and above.

Yes, ChangeTower offers a native iOS app with push notifications, a capability SiteGauge does not currently have. SiteGauge relies on email plus Slack, Teams, Discord, Telegram, Google Chat, SMS and webhook alerts instead.

SiteGauge is better for compliance because it can export tamper-evident audit evidence: signed with Ed25519, RFC-3161 trusted-timestamped, and publicly verifiable. ChangeTower keeps timestamped screenshot and HTML archives but without cryptographic verification.

Domain scanning is available on ChangeTower's Enterprise tier only. SiteGauge offers sitemap-based whole-domain monitoring with tiered cadence on every plan, including Free, with the number of tracked pages scaling by plan (from 10 pages on Free up to unlimited on Enterprise).

ChangeTower exposes integration primarily through its native Zapier app and webhooks, and references an API token for connecting services; a full standalone read/write REST API is not clearly documented. SiteGauge includes its full read/write API on every plan.

Yes. When a change is significant, SiteGauge reads it with AI and produces a plain-English summary that says what changed, categorises it (pricing, messaging, product or SEO), and scores how important it is, alongside before/after visual and text diffs. Routine, low-importance edits are still logged, without spending an AI pass on them. This is its core differentiator versus tools that only show a raw diff.

Yes. Point SiteGauge at any pricing page and it detects changes to prices, plan structure, and CTA copy, then sends an alert with an AI summary explaining exactly what shifted. It captures before/after screenshots so you can see the change visually.

Yes. SiteGauge has a free plan ($0) that monitors up to 5 pages with daily checks, AI change summaries, and email alerts plus an RSS change feed, no credit card required. Paid plans add more monitors, faster cadence, and team integrations.

Yes. When an ordinary fetch is blocked, SiteGauge renders the page through a residential browser so it can still capture bot-protected sites behind Cloudflare or Akamai. Most monitors never need this, so it is reserved for the pages that do.

Yes, on the Business and Enterprise plans. SiteGauge exports signed, tamper-evident evidence of a change, using an Ed25519 signature (with an RFC-3161 trusted timestamp attached when the timestamp authority is reachable), packaged as a downloadable bundle with a public verification page that anyone can check against our published key. Most monitoring tools do not offer independently verifiable evidence, which makes SiteGauge a fit for compliance and legal teams.

Email alerts and an RSS change feed are on every plan, including Free. Slack, Microsoft Teams, Discord, Telegram, Google Chat, webhooks, SMS and Google Sheets are available on Standard and above. You can also connect Zapier (via webhooks today; native app pending directory listing) and n8n (via webhooks) to reach thousands of other apps, and drive everything from your AI assistant through the built-in MCP server.

Yes. SiteGauge ships an MCP server, so AI assistants like Claude, ChatGPT and Cursor can connect to your account, create monitors, read change history and pull exactly what changed on a page, without leaving your assistant. You connect once by signing in, with no API key to copy and paste.

Yes. SiteGauge importance-scores every change, and you can set an alert filter so you only hear about the changes that matter, such as a competitor's price or pricing-page edit, while routine tweaks are still logged quietly. It cuts alert noise sharply without hiding anything.

Paid plans include a set number of editors plus unlimited free read-only viewers, so you can share monitoring across a whole team or with clients without paying per seat for people who only need to view results.

Yes. Unlimited free viewers, multiple workspaces, tag-scoped digests, and competitor monitoring make SiteGauge well suited to agencies managing monitoring across many clients and reporting results back to them.
