Comparison
Korvus vs Sentry
Sentry is a developer tool: it captures an application's errors, traces, replays and profiles and links them together. Korvus speaks to the CMO in lost euros. Both watch the site in production, but for different people.
Who each tool suits best
Choose Korvus if...
- The recipient is a CMO or ecommerce manager who wants a euro amount
- Your costliest losses are not JavaScript exceptions: dead pixel, diverted promo code
- You watch paid traffic sent to out-of-stock products
- Nobody can add an SDK to the site's code
- You want your data hosted in France
Choose Sentry if...
- Your developers want stack traces, errors grouped into issues and assignments
- You want to follow a request from the frontend to the backend, with traces and profiles
- You also monitor scheduled jobs (cron) or endpoint uptime
- You want to start free: the Developer plan is free for one user
- Your stack is among the 100+ platforms and frameworks supported

Frequently asked questions
Does Sentry detect dead pixels?
Sentry captures unhandled exceptions and the errors you send it. A pixel that stops firing does not necessarily throw an exception, so there is nothing to capture. The Sentry pages we read describe no check on conversion pixels. Korvus watches that signal and alerts you with the euro impact.
My dev team already uses Sentry. Why add Korvus?
Your dev team uses Sentry to fix bugs. The leaks that cost the most (dead pixel, sponsored out-of-stock products) do not always produce a technical error. Korvus detects them and prices the impact so the CMO can prioritize.
Can Sentry alert on a drop in revenue?
Sentry's alert documentation describes rules on issues and thresholds on errors or traffic, with no mention of revenue or business metrics. Korvus puts a euro figure on every leak it detects and says what to fix.
Is Sentry free?
Sentry has a free Developer plan for one user (5,000 errors and 50 replays according to its pricing page, read on 26 October 2026). Team and Business are paid, Enterprise is custom. Korvus does not list a free plan: pricing is by quote.
Where is the data hosted?
Sentry lets you store data in the United States or the European Union, in Frankfurt. Korvus hosts data in France (Scaleway, Paris), with no transfer outside the European Union.
Can you install Sentry without a developer?
The Loader Script is the simplest method: you copy the script tag from the Sentry interface and include it as the first script on the page. For readable stack traces on minified code, source maps must be public or uploaded to Sentry, which takes a technical step. The documentation we read does not mention Google Tag Manager.
