PingChange

I kept seeing the same problem show up across teams I worked with and talked to.

A sales rep finds out a competitor dropped their price - from a prospect, mid-negotiation. An engineer spends two hours debugging a 422 error that traces back to a required field that appeared in a third-party API spec three weeks ago. A founder realises a key vendor updated their data processing agreement without sending any notice.

In every case, the information was public the whole time. The problem was nobody was systematically watching.

That is what led me to build [PingChange](https://pingchange.com).

What it does

PingChange monitors websites and API specs on a schedule and alerts your team when something meaningful changes.

The core loop: paste a URL, set a frequency, define what you care about, connect Slack or email. When something changes, you get a diff and a plain-English summary of what actually changed — not a screenshot, not "page changed."

The things that make it different from the simpler tools in this space:

- AI-assisted filtering. You write something like "alert when a plan price or feature limit changes, ignore testimonials and cookie banners." The AI judges each detected change against that intent. This cuts false positives dramatically on pages with a lot of dynamic content.

- OpenAPI / Swagger spec monitoring. If your team depends on partner APIs, you can point a monitor at the spec URL. It understands the semantics — new required fields, deprecated paths, type changes — and explains the drift in readable language. Most web change tools treat a spec file as a text blob. This doesn't.

- Multi-region checks. Run monitors from US, EU, Middle East, Africa, and other regions. Some vendor pages show different pricing to different geographies. Single-location tools miss this entirely.

- Anti-bot resolution. Paid plans use smart browser sessions to keep checks working on pages protected by CAPTCHAs and bot-detection. Most tools silently fail on these pages.

Alerts route to Slack, email (immediate or daily/weekly digest), Telegram, webhooks, PagerDuty, Zapier, Make, and n8n.

Who is actually using it

The use cases that keep coming up:

1. Competitive intel — product and sales teams watching competitor pricing pages, feature tables, and changelog pages. When a competitor moves, they know the same day instead of from a prospect two weeks later.

2. API contract monitoring — engineering teams watching OpenAPI specs for services they integrate with. Catching breaking changes before they hit production.

3. Compliance — legal and compliance teams tracking vendor terms, privacy policies, and data agreements that change without formal notice.

4. Your own pages — catching accidental CMS publishes, A/B test leakage, and deploy issues on your own pricing and product pages before customers do.

The business

Free plan to get started (2 monitors, 100 checks/month). Paid plans from $4.99/month. Freemium, flat-rate tiers, annual billing available.

Still early. Working on growing the user base, building out the comparison content so teams searching for "how to monitor competitor pricing" or "OpenAPI change detection" find PingChange, and iterating on the product based on what real users actually need.

What I'd love to hear from this community

- If you have ever been burned by a competitor pricing change or a third-party API breaking your integration - how did you find out? How long did it take?

- If you are already monitoring web or API changes, what are you using and what does it not do well?

- If you have gone through directory submissions, getting SEO traction, or early distribution for a B2B SaaS tool - what actually moved the needle?
