Why teams move on from OnWebChange
The gaps that most often send teams looking elsewhere, from our own research into OnWebChange (last reviewed August 2026). Every tool has gaps; OnWebChange’s genuine strengths get their own section further down this page.
Where OnWebChange falls short
Thin integration set: email, push, URL callback and RSS feed only, with no native Slack, Teams, Telegram, or documented API
No real AI change intelligence: no categorisation (pricing/messaging/product), no importance scoring
No team collaboration: no documented roles, seats, viewers, comments, or shared workspaces
Visual monitoring is light (screenshot-on-change) rather than true multi-viewport before/after visual diffing
Dated positioning and very limited third-party review footprint make it hard to validate at scale
No scheduled report exports, no enterprise tier, no SSO, not built for larger or compliance-driven buyers
What you gain by moving to SiteGauge
Moving does not mean giving up day-to-day monitoring. You keep watching the same pages and add the layers below.
AI that explains, not just detects
Every significant change is categorised (pricing, messaging, product, SEO) and importance-scored, with before/after visual and text diffs. You get the “so what”, not a raw diff, and you can choose to be alerted only on the important ones.
Audit-grade change evidence
On Business and Enterprise, export signed, tamper-evident change records (Ed25519 signature, plus an RFC-3161 trusted timestamp when the timestamp authority is reachable) with a public verification page anyone can check against our published key. Built for compliance and legal teams.
Unlimited free viewers
On every paid plan, share monitoring with your whole team or your clients at no extra cost. Each plan includes its editors (1 on Standard, 3 on Pro, 10 on Business), and read-only viewers never use a seat.
Reaches sites that block bots
Residential rendering reaches many Cloudflare- and Akamai-protected pages that a plain fetch cannot load.
Works inside your AI tools
A built-in MCP server lets Claude, ChatGPT and Cursor create monitors, read change history and pull what changed, straight from your AI assistant.
Alerts in every tool your team uses
Email and an RSS feed on every plan, and from Standard: Slack, Teams, Discord, Telegram, Google Chat, webhooks, SMS and Google Sheets, plus Zapier and n8n via webhooks (native apps pending directory listing), so a change lands where your team already works, not just in your inbox.

Your migration plan: OnWebChange to SiteGauge
A typical switch takes well under an hour.
1Export your existing trackers from OnWebChange (it supports bulk CSV import/export) to get the full list of monitored URLs and any CSS selectors.
2Create monitors in SiteGauge for each URL; reuse your CSS/XPath targeting via SiteGauge's ignore rules and selectors, and enable multi-viewport visual monitoring where you want it.
3Reconnect alerts: wire up email plus native Slack, Teams, or webhook channels (Standard and up), and set keyword alerts where you previously used keyword filters.
4Set check frequency per plan (hourly on Standard up to 5-minute on Business, out of the plan's monthly check allowance) and add whole-domain/sitemap monitoring for sites where you tracked many pages.
5Invite teammates with Owner/Admin/Member roles (1 editor seat on Standard, 3 on Pro, 10 on Business) and add stakeholders as unlimited free read-only viewers.
6For anything you tracked for compliance, enable SiteGauge's signed audit-evidence export (Business and Enterprise plans) to replace OnWebChange's public change logs with tamper-evident records.
Nothing is at risk while you do it: your OnWebChange history stays in OnWebChange until you cancel, so export anything you need to keep first, and you can run both tools in parallel for a cycle to confirm SiteGauge catches the same changes before you cancel OnWebChange.
Worried it will miss something?

Monitors files and documents including PDFs and images, something many rivals lack (SiteGauge covers PDF, Word and Excel text but not image files)
Public, shareable change logs with version comparison, a distinctive, transparent audit trail
Global tracking locations and AI translate/summarise for cross-language monitoring
What SiteGauge costs instead of OnWebChange
Budget the move like for like: every tier of each tool, and the model each uses. Pricing as last reviewed (August 2026); confirm on each vendor’s site before you decide.
Standard: $24/mo, 30 monitors, 4,000 checks/mo, down to hourly on a small set
Mid-tier
Pro: $99/mo, 100 monitors, 10,000 checks/mo, down to 15-minute on a small set
Top / enterprise
Business $199/mo (300 monitors, 24,000 checks/mo, down to 5-minute on a small set) + custom Enterprise
Model
Checks-based with a predictable hard cap: monitors pause at your allowance, no surprise overage bills or forced upgrades
Checks are one monthly pool shared by all monitors, so the fastest cadence suits a few monitors: about 5 hourly on Standard, 3 at 15 minutes on Pro, or 2 to 3 at 5 minutes on Business. Editors: 1 on Standard, 3 on Pro, 10 on Business, plus unlimited free read-only viewers on every paid plan.

Run both before you cancel anything
The safest migration is the one you can verify. Three moves, no leap of faith.
1
Recreate your monitors
Add the pages you watch in OnWebChange today to SiteGauge on the free plan, no credit card.
2
Compare for a cycle
Run OnWebChange and SiteGauge side by side for a billing cycle or two and compare what each catches.
3
Cut over when confident
Export any OnWebChange history you need to keep, then cancel only once you are confident nothing is missed.
SiteGauge as a OnWebChange alternative: FAQ
No. You recreate the URLs you monitor today in SiteGauge, map any OnWebChange selectors to SiteGauge ignore rules and keyword alerts, and reconnect your alert channels. Most teams migrate in under an afternoon, and you can run both tools in parallel for a cycle to confirm SiteGauge catches the same changes before you cancel OnWebChange.
Your OnWebChange history stays in OnWebChange until you cancel, so export anything you need to keep first. SiteGauge starts a fresh baseline the moment you add a page and builds its own change history from there, with retention that scales by plan.
Yes, and it is the safest way to migrate. Point both tools at the same pages for one or two billing cycles, compare what each catches, then cut over to SiteGauge once you are confident nothing is missed.
OnWebChange is among the cheapest in the category. It has a free plan (3 trackers, daily checks), with paid plans starting around €0.89/month (Lite) up to roughly €8.99/month (Turbo-100, 100 trackers with faster checks). Pricing is based on the number of page trackers and check frequency rather than a checks quota.
OnWebChange offers AI translation and content summarisation, which help with cross-language monitoring. It does not categorise changes (e.g. pricing vs messaging) or score their importance. SiteGauge's AI summarises, categorises, and importance-scores each change so you can triage quickly.
OnWebChange's documented alert and output channels are email, mobile push, URL callback/webhook, and an RSS feed. It does not offer native Slack, Teams, or Telegram integrations, and a public API is not documented. SiteGauge offers native Slack/Teams/webhook alerts from the $24 Standard plan, plus a full read/write API on every plan.
OnWebChange captures a screenshot of the page when a change is detected and can target specific elements, so it has light visual capability. It is not a visual-first tool with multi-viewport before/after visual diffing the way SiteGauge or Visualping are.
Yes, OnWebChange can track PDFs, images, and other files for changes, which is a genuine strength. SiteGauge also monitors PDF, Word and Excel documents by extracting and diffing their text, but it does not track image files, so if image-file monitoring is your main need, OnWebChange may suit you better.
OnWebChange offers public, shareable change logs with version comparison, which provide a transparent history, and it can monitor PDFs. However, it lacks signed, tamper-evident records. SiteGauge provides tamper-evident audit evidence (Ed25519-signed with a public signature-check page, plus an RFC-3161 timestamp when the timestamp authority is reachable; Business and Enterprise plans), which is stronger for legal or regulatory needs.
Common alternatives include SiteGauge (for AI analysis, integrations, and team/enterprise features) and Visualping (for visual-first monitoring). SiteGauge is the strongest pick if you want change intelligence and team collaboration rather than just low-cost alerts.
Yes, and for most switchers it is the biggest change of habit. Instead of opening a raw diff to work out what happened, you get a plain-English AI summary that says what changed, categorises it (pricing, messaging, product or SEO), and scores how important it is, with before/after visual and text diffs underneath. Routine, low-importance edits are still logged, without spending an AI pass on them.
Yes. If you tracked pricing pages in your old tool, point SiteGauge at the same URLs: it detects changes to prices, plan structure, and CTA copy, then sends an alert with an AI summary explaining exactly what shifted, plus before/after screenshots so you can see the change visually.
Yes, and it is the easiest way to test a migration: the free plan ($0) monitors up to 5 pages with daily checks, AI change summaries, and email alerts plus an RSS change feed, no credit card required. Recreate a handful of your monitors on it, compare results side by side, and upgrade only when you are ready to move the rest.
Often. If bot-protected pages kept failing in your previous tool, test them early in your migration: when an ordinary fetch is blocked, SiteGauge can switch to a residential browser, which reaches many pages behind Cloudflare or Akamai. It is not guaranteed: some heavily protected sites still block capture, and these renders use a monthly allowance on each self-serve plan. Most monitors never need this, so it is reserved for the pages that do.
Yes, on the Business and Enterprise plans, and it is usually a capability you gain in the move rather than carry over. 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. That makes it 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, so you can reconnect the channels you used before rather than changing how your team hears about changes. Zapier (via webhooks today; native app pending directory listing) and n8n (via webhooks) reach thousands of other apps, and the built-in MCP server connects your AI assistant.
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. During a migration that is a quick way to recreate monitors: connect once by signing in, with no API key to copy and paste, then ask your assistant to create monitors for the pages on your old list.
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. If alert noise was part of why you are leaving your current tool, set the filter up as you migrate rather than after.
Paid plans include a set number of editors plus unlimited free read-only viewers. If your previous tool charged per seat, this usually changes who you invite: bring the whole team or your clients in as free viewers, and pay only for the people who edit monitors.
Yes. Unlimited free viewers on every paid plan, tag-scoped digests and up to 3 workspaces on Pro (10 on Business), and competitor monitoring make SiteGauge well suited to agencies moving client monitoring across from another tool, and to reporting results back without paying per seat for people who only view.
Still weighing it up?
Start on the free plan, keep watching the same pages, and see for yourself what the AI summaries add. No credit card.
Website monitoring is the practice of automatically watching one or more web pages and being alerted when they change. Rather than revisiting pages by hand, software takes regular snapshots, compares them, and flags differences, from text edits and price changes to layout redesigns and downtime.
What is competitor monitoring?
Competitor monitoring is tracking the websites of rival companies, their pricing, features, messaging, and content, to detect strategic moves as they happen. It turns a competitor's public website into an early-warning signal for launches, repositioning, and price changes.
What is website intelligence?
Website intelligence goes beyond detecting that a page changed to interpreting what the change means. It combines change detection with context (categorisation, severity, and business impact) so teams get insight, not just raw diffs.
What is AI-powered website intelligence?
AI-powered website intelligence uses large language models to read each detected change and explain it in plain English: what changed, which category it falls into (pricing, messaging, product, SEO), and how important it is. It replaces manual diff-reading with an analyst-style summary, which is the core of what SiteGauge does.
A note on accuracy
Some OnWebChange details were harder to verify (confidence: medium). We could not independently confirm: Whether OnWebChange offers any public/developer API (not documented on their site; third-party sources say no, but we could not fully confirm); Exact history/retention periods per plan; Precise check-frequency caps per tier (Turbo tiers are 'faster'; ~5-minute fastest is stated but per-tier specifics are unclear); Annual pricing and any free-trial terms for paid plans; Whether EUR prices shown are the user's exact local pricing; Current third-party review ratings (review presence on G2/SourceForge/SaaSworthy is near-zero, limiting validation); Depth of visual diffing: screenshots are captured on change, but true before/after visual-diff UI is not clearly documented; Whether Slack/Teams can be reached indirectly via the URL callback/webhook (native support is absent). Vendor features and pricing change often. Please confirm against OnWebChange’s own site before deciding.
