Raygun started in Wellington, New Zealand, as a crash reporting tool for .NET applications. Today it is a full performance and error monitoring platform used by tens of thousands of teams — from startups to large enterprises.
From crashes to watching users
Raygun’s story is telling: the company realized that knowing “something crashed” is not enough. You need to see exactly how a user interacts with the app, which pages are slow, which requests are degrading. So three layers appeared in the product:
- Crash Reporting — detailed error reports with diagnostics;
- Real User Monitoring (RUM) — performance measurement through real users’ eyes;
- APM — server-side traces and metrics.
Together they deliver what Raygun calls a “single pane of glass for quality”: from frontend to backend.
What makes Raygun stand out
The main feature is diagnostic depth. Every error report shows the exact line of code, affected versions, reproduction frequency, trends and even a predicted impact on users. Plus powerful search and filtering by custom tags, environments and versions.
.NET support deserves special mention: historically Raygun is one of the best choices for the Microsoft ecosystem, including Xamarin and Blazor.
Pricing
Raygun’s pricing is built on the number of events (crashes and RUM sessions). There is a free trial, and paid plans start at roughly $4/month for basic crash reporting, up to several hundred dollars for full APM + RUM at large volumes. The entry threshold is low for small businesses.
Limitations
Raygun is good but not all-encompassing: advanced log analytics (Loki/ELK style) and deep integration with infrastructure monitoring are secondary here. If you need a single “logs + metrics + traces” stack, Raygun will have to be supplemented.
Partner program
Raygun has no public affiliate network with referral links. Monetization for partners is possible through referral agreements with the company, but there is no mass program for bloggers. Thematic traffic is what this review really delivers.
Verdict
Raygun is a strong choice for teams that need crashes, user monitoring and server-side APM in one window. It’s especially pleasant for .NET stacks, where alternatives are weaker.
