What is a diff?
A "diff" is Pulse's record of a single pricing-page change. Pulse captures company pricing pages continuously and creates a diff whenever something changes — a price moves, a plan or feature is added or removed, a limit increases, or positioning copy is updated. Each diff pairs the before and after so you can see exactly what changed and when.
Where to find diffs
Across the market — click Diffs in the navigation to browse changes across all tracked companies.
For one company — open any company profile and scroll to Most Recent Diffs and Historical Diffs.
Reading the Diffs feed
On the Diffs page, each row shows the company, the period (e.g. 2026W21), a plain-English headline, a change-type badge, and a one-line summary of what moved. You can refine the feed with:
Weekly / Quarterly — switch the time granularity.
Newsworthy — Show highlights surfaces only the most significant changes; All shows everything.
Event Types — filter by Pricing, Packaging, or Product changes.
Companies / Watchlists — narrow to specific companies, or (on Pro) just your watchlisted ones.
Periods — select which weeks or quarters to include.
Change-type badges
Every change is tagged so you can scan quickly. Common badges include Price Increased / Price Decreased, Plan Added, Feature Added / Feature Changed, Capacity Increased, Add-On Added, and Positioning Changed.
Reading a single diff
Click any diff to open its detail view, which shows:
Event summary — a short, plain-English description of what changed and its category (Pricing, Packaging, or Product).
Before / After screenshots — the pricing page on each date, side by side, with the changed region highlighted so you don't have to scan the whole page. Use the zoom controls to inspect details.
Dates — the "before" and "after" capture dates.
Previous / Next — step through that company's other diffs, plus Full screen and Explore views.
Credit cost
Viewing a diff in the app costs 15 credits, charged once per diff — if you open the same diff again later, you're not charged again. Public diffs are free for everyone. See How credits work.
Tip: track changes automatically
Instead of checking the feed manually, add the companies you care about to a Watchlist (Pro) and set up a Digest or real-time alert so relevant diffs come to your inbox. See Sharing reports with your team.
