Website Change Tracker — Competitor Monitoring

Know the moment a competitor changes their pricing, ships a feature, or starts hiring — without checking a single page yourself.

Competitors move quietly: they bump a price, add an Enterprise tier, post three senior roles, soften a tagline — and you hear about it weeks later from a prospect. Checking by hand doesn't scale.

So this Actor watches for you. Paste the pages to track; on every run it opens each one in a real browser, compares it to the last snapshot, and uses AI to tell you what changed and how big a deal it is (a 1–5 score). You get a Slack digest on your schedule, instant alerts for urgent moves, and a growing Notion archive of every change. Slack and Notion are optional.

🧪 Early access. Priced lean — a $0.05 per-run start fee, plus your Apify usage for the crawl, plus a small per-summary AI charge (free with your own AI key). No per-page or per-change markup. See Costs. Something off? Open an issue on the Issues tab. 🙏

Who it's for

• Founders & product marketers — "tell me the day a rival changes pricing or packaging."
• Competitive intelligence — a weekly "what moved across our competitor set" in one Slack channel.
• Sales & RevOps — an instant ping on a new partnership, marquee customer, or leadership change.
• Recruiters — watch careers pages for hiring sprees and new roles or regions.
• Content & SEO — catch rivals' new posts, changelogs, and announcements early.

What you get

• Changes, read for you — each page is diffed against last time and summarized in a sentence ("Pro plan rose $49→$59 and an Enterprise tier was added"), with a 1–5 significance score so cosmetic edits don't drown out real moves.
• A digest, not a list — on your schedule, Slack gets a grouped "what moved" rundown, scannable in 30 seconds.
• Instant alerts — set a threshold and get a Slack ping the moment a change lands at or above it.
• A Notion archive — every change becomes a row in a Website Changes database the Actor builds for you. Searchable, filterable, yours.
• Company briefs — the first time it sees a competitor, it can write a one-time brief (positioning, pricing, product focus, hiring signals).

Set it up in 2 minutes

1. Add the pages. Paste competitor URLs, one per line — the only required field. A bare domain (competitor.com) works; a root URL watches the whole site (up to 50 pages/run); a path like competitor.com/pricing watches just that section.
2. Pick your AI (optional). Default Claude Haiku 4.5 on our key needs no setup. Switch to Sonnet for sharper reads, or GPT/Gemini with your own key.
3. Add Slack (optional). In Apify Console → Settings → Integrations → MCP Connectors, add https://mcp.slack.com/mcp and authorize it; invite the bot to your channel. Then set Slack connector + Slack channel.
4. Add Notion (optional). Add https://mcp.notion.com/mcp and pick it in Notion connector — the Actor builds the database for you. To keep it in a specific page, paste that page's ID in Notion page ID (the 32-char code at the end of its URL); leave blank for your workspace root.
5. Schedule it. On the Schedule tab, run it daily at (or after) your digest hour (UTC) — daily runs catch changes, and the run on your digest day also posts the rundown.

Input

Only Pages to watch is required; everything else has sensible defaults.

Field	What it is	Default
Pages to watch (urls)	Competitor URLs, one per line (bare domain, root, or path)	— (required)

Send time / day (rundownHour, weeklyRundownDay)	When the digest goes out (UTC)	9:00, Monday
Immediate critical alerts (criticalAlertLevel)	Instant Slack alert at/above a significance	Never
Company analysis brief (companyAnalysis)	One-time competitor brief: never / on first run / force now	Never
Slack connector + channel (slackConnector, slackChannel)	Authorized Slack MCP connector and target channel	— (skip = no Slack)
Notion connector (notionConnector)	Authorized Notion MCP connector	— (skip = no Notion)
Notion page ID (notionParentPage)	Page ID (32-char code from its URL) to build the database inside; blank = workspace root	—
AI model + key (model, llmApiKey)	Which AI writes summaries; key required for GPT/Gemini, optional for Claude	Claude Haiku 4.5
Reset baseline (resetBaseline)	Wipe snapshots and re-baseline every page	off
Proxy (proxyConfiguration)	Proxy for fetching pages; Residential for anti-bot sites	Apify Proxy on

Output

One row per page per run — a baseline row the first time a page is seen, then a changed row whenever a real diff is found:

{
  "url": "https://competitor.com/pricing",
  "status": "changed",
  "changeType": "pricing",
  "significance": 4,
  "summary": "The Pro plan rose from $49 to $59/month and a new Enterprise tier was added.",
  "evidence": ["- $49/month", "+ $59/month", "+ Enterprise — contact sales"],
  "checkedAt": "2026-06-08T09:00:12.000Z"
}

Key fields: status (baseline / changed), changeType (pricing, product, partnership, hiring, messaging, content, legal, cosmetic, other), significance (1 cosmetic → 5 major), summary, evidence (telling diff lines), and diff (the full diff behind it). Download as JSON, CSV, Excel, or HTML from the Output tab.

Costs

Pay only when you run — no subscription, no per-result markup:

• $0.05 per run start — one baseline fee (billed even with your own AI key).
• Apify platform usage (compute + proxy) for the crawl — the main variable cost, since it renders each page in a real browser. Scales with pages tracked and run frequency.
• A small AI charge per summary — $0.02 (Haiku) or $0.06 (Sonnet), one flat charge per write-up (each change, the digest, each brief). $0 with your own Anthropic key, or with GPT/Gemini (you pay that provider directly).

The first run writes no summaries (just a baseline per page), so it's only the start fee + crawl. Tips: track specific paths over whole sites, keep the default Haiku, and run daily, not hourly.

Use it from your AI assistant (MCP)

This Actor uses MCP connectors for delivery — Slack (digests + alerts) and Notion (the archive) — authorized once in Apify Console → Settings → Integrations → MCP Connectors, so it never sees your tokens. You can also run the Actor itself from any MCP client (Claude, Cursor, …) via the Apify MCP server (https://mcp.apify.com) with your Apify token — just ask "what changed on my competitors this week?"

FAQ

Why no changes on the first run? It stores a baseline first (you'll see a baseline row per page). Change detection starts on the second run, once there's something to compare against.

Why didn't my digest arrive? Digests only send on a run at or after your chosen UTC hour (and, for weekly, on your day). Schedule the Actor to run daily at your digest hour — the simplest reliable setup.

Do I have to set up the Notion database? No — the Actor builds it. By default it lands at your workspace root; paste a Notion page ID to keep it inside that page instead.

Can I use my own AI account? Yes. GPT/Gemini require your key; for Claude it's optional (blank = built-in key, or paste your Anthropic key to bill your own account and skip our AI charge).

A site is behind anti-bot protection? Switch Proxy to Residential. If a page still returns no content, the log flags a possible block.

Is this allowed? It reads publicly accessible pages, like a browser does. Review each target's Terms of Service, robots policy, and your local laws first, and don't collect personal or restricted data.
