Continuous profiling helps developers inspect application performance as software runs. Compare profiling types, language support, and source map support against the technologies you use, then weigh continuous alerts and data retention for your monitoring needs. Deployment options, free-plan availability, and paid-from pricing provide additional points for evaluating fit and cost. Guance Container Monitoring, Middleware, and Coroot are options to consider across these listed dimensions. Think about what you need to profile, how you want to be alerted, and how long performance data should remain available.
