Overview
Sentry
Sentry helps you see exactly what is broken in your code and why it is happening. Instead of digging through messy logs, you get real-time alerts that pinpoint the specific line of code causing an error, the users affected, and the environmental context. This allows you to fix bugs in minutes rather than hours, ensuring your application remains stable and your users stay happy.
You can also monitor your application's performance to find slow database queries or sluggish API calls that frustrate your customers. It supports over 100 languages and frameworks, making it a versatile choice whether you are building a mobile app, a website, or backend services. The platform scales with you, offering a robust free tier for individual developers and comprehensive plans for growing engineering teams.
Splunk On-Call
Splunk On-Call, formerly known as VictorOps, is a purpose-built incident management platform designed to make on-call rotations less painful for your engineering teams. You can automate the entire incident lifecycle by routing alerts from your monitoring tools directly to the right person at the right time. By centralizing your alert data, the platform ensures that your team has the full context needed to diagnose problems without switching between multiple tabs or tools during a crisis.
You can manage complex on-call schedules, set up automated escalation policies, and use native mobile apps to respond to incidents from anywhere. The software focuses on reducing your Mean Time to Resolution (MTTR) by providing a collaborative timeline where your team can chat, share snippets, and track remediation steps in real-time. It is particularly effective for DevOps and SRE teams in mid-market to enterprise organizations who need to maintain high service availability.
