Learn what Sonar is, what it tracks, and how ChangeCrab turns public changelog and status-page activity into actionable competitor intelligence.
Sonar is ChangeCrab's competitor intelligence workspace. It watches public changelogs, RSS feeds, and status pages, then turns that activity into heartbeat charts, competitor cards, signals, and AI-generated briefs your team can actually use.
Sonar helps product, marketing, and leadership teams answer a simple question: what is the rest of the market shipping right now, and how fast are they moving?
Instead of manually checking competitor changelogs every week, Sonar keeps a structured workspace of the companies you care about and highlights patterns that are easy to miss when you only scan updates one by one.
The heartbeat chart compares your own update cadence with tracked competitors over a 3-month or 6-month window. You can switch the visualization and optionally layer in changelog engagement or outage data.
Each tracked company gets a compact card and a detailed workspace view. This gives you quick access to last update timing, change counts, changelog coverage, status-page coverage, and the underlying activity history.
Signals call out notable moments such as acceleration, deceleration, quiet periods, or theme matches. They are designed to help you focus on what changed in the market instead of rereading everything.
Sonar can summarize observed activity into short briefs that give teams a faster starting point for competitor reviews, launch prep, and leadership updates.
If a tracked competitor has a public status page, Sonar can keep that alongside changelog activity so you can see release pace and operational reliability in one place.
Full Sonar access is available on paid plans and active trials. Free accounts can open the Sonar preview to see the workflow and outputs, but live tracking, settings, alerts, and report generation stay locked until Sonar is enabled on the account.
Sonar is built around observed public sources. It tries to discover changelogs, feeds, and status pages automatically, and it can also accept manual public links when auto-discovery needs help.
That means Sonar is strongest when competitors publish clear public updates. If a company ships quietly or only communicates inside the product, Sonar may have thinner coverage for that competitor.
Sonar is not a full replacement for deep competitive research. It is your always-on monitoring layer: the place that tells you who sped up, who went quiet, what themes keep appearing, and which competitors deserve a deeper look right now.
