OnWebChange pricing in plain numbers, and what a bigger budget buys
Five euro plans from free to 8.99, a check pool the public table leaves blank, and when AyeWatch's higher price pays back in time.
OnWebChange pricing is unusually low for a monitoring tool, and that is worth taking seriously before you spend more elsewhere. This analysis lays out what each OnWebChange plan includes, what the numbers leave unsaid, and when paying more for an AI monitor like AyeWatch returns the money in time saved.
The plans
From OnWebChange's pricing page, October 2026. Prices are monthly, in euros.
| Plan | Price | Page trackers | What it adds |
|---|---|---|---|
| Free | €0 | 3 | Daily checks, email, Pushover and callback alerts, CSS selection, PDF tracking, rules |
| Lite | €0.89 | 10 | Faster and more checks, 3 extra alert emails per tracker |
| Standard | €2.79 | Unlimited | Highlighted difference reports, history and charts, groups, CSV import and export, public tracker library, 20 alert emails per tracker |
| Turbo-50 | €4.99 | 50 | Standard features, high-frequency checks |
| Turbo-100 | €8.99 | 100 | Standard features, high-frequency checks |
Custom plans are available by email.
What the table does not say
Two numbers are missing from the public page: the fastest interval per plan and the monthly check allowance. OnWebChange's features page says checks can run as often as every 5 minutes, and a note on the pricing page describes checks per month as one pool for the whole account that you split between trackers.
That pool is the real limit. A tracker checked every 5 minutes uses about 8,600 checks in a 30-day month. Ten of them would need over 86,000. Before you plan around high frequency, find out the pool size for your plan.
Note also the odd shape of the ladder. Standard offers unlimited trackers at €2.79, while Turbo-50 costs more and caps you at 50. The Turbo plans are paying for frequency, not count.
Where the real cost sits
For an operator, the subscription is rarely the expensive part. At these prices the cost of OnWebChange is the time someone spends:
- Reading alerts that turned out to be cosmetic edits
- Rebuilding selectors after a site redesign
- Missing a change because a broken selector went quiet
If a team member spends an hour a week on that, the tool is no longer the cheapest line in the budget.
How AyeWatch prices it
AyeWatch costs more per month. It starts with a Free Preview of three lifetime monitoring runs across up to three topics, with no card, and paid plans start at $9 a month. You can cancel a paid plan at any time. The price is higher than OnWebChange's euro plans, so the question is whether the work it saves is worth it.
AyeWatch's answer is that you stop reading alerts that do not matter. Instead of a tracker per page and a set of CSS selectors, you write one sentence about what you care about, and AyeWatch judges each change against it. Each alert comes with a short summary, so you can tell in a few seconds whether to act.
What the extra money buys:
- Rules in plain English, judged by meaning, so cosmetic edits and layout moves do not trigger alerts
- Several URLs under one rule, instead of one tracker per page
- Topic monitoring across news, forums, blogs and social sources such as X, Reddit and LinkedIn
- Native iOS and Android apps; on paid plans, email, Slack, Discord, signed webhooks, a REST API and an MCP server
A simple way to decide
Work out what an hour of your team's time costs. If OnWebChange alerts take less than that each month to sort through and maintain, stay. The tool is cheap and has run since 2009.
If the noise or the maintenance costs more than the gap between €2.79 and $9, the switch pays for itself. Start with the trackers that fire most often for the least reason, rebuild them as AyeWatch rules on the Free Preview, and compare a week of alerts.
OnWebChange keeps an edge for PDF and file tracking and for login pages reached with custom headers. Leave those where they are. For the feature-by-feature view, see AyeWatch's OnWebChange comparison.
