Glances vs Middleware
Side-by-side comparison of features, pricing, ratings, and alternatives.
Glances is an open‑source, cross‑platform monitoring tool that provides a concise, real‑time view of system resources such as CPU, memory, disk I/O, network, and processes. It runs on Linux, Windows, macOS and can be accessed via a web interface, making it ideal for both local and remote monitoring. Designed for system administrators and DevOps teams, Glances aggregates metrics into a single dashboard, supports customizable alerts, and integrates with scripts or APIs for automated workflows. Its lightweight design ensures minimal overhead while delivering comprehensive performance insights.
Middleware is a full-stack observability platform that unifies infrastructure monitoring, application performance monitoring (APM), real-user monitoring (RUM), logs, synthetic testing, and LLM observability in one place. Instead of juggling multiple tools, engineering teams can ingest all telemetry data and view it on a single timeline, making it easier to detect issues and move from symptom to root cause quickly. At the core of the platform is OpsAI, an AI-powered SRE agent. It analyzes traces, RUM data, and logs to automatically detect production issues, pinpoint the exact line of code responsible, and even open a pull request with fixes. Users can also ask for dashboards, charts, or queries in plain English, eliminating the need to learn a custom query language. Middleware is built for scale and reliability, with native OpenTelemetry support, 450+ integrations, petabyte-scale data handling, and enterprise-grade security including SOC 2, GDPR, ISO 27001, and HIPAA readiness. It offers a completely free tier to get started and provides 24/7 support from real engineers rather than chatbots.
- Fully open‑source and free
- Runs on all major operating systems
- Lightweight with low resource overhead
- Extensible via plugins and API
- One platform for infrastructure monitoring, APM, RUM, logs, synthetic testing, and LLM observability
- OpsAI goes beyond detection by suggesting root-cause fixes and opening pull requests
- OpenTelemetry-native design prevents vendor lock-in
- 450+ integrations and no-sampling telemetry ingestion
- No native mobile app
- Limited built‑in visualization compared to commercial tools
- Alerting requires manual configuration or external scripts
- No transparent pricing details are shared on the website, so estimating costs likely requires contacting sales.
- The AI SRE agent's auto-fix capabilities depend on additional repository and CI/CD integrations and permissions being configured.
- Because it covers so many signals, maximizing the platform's value may require significant setup and tuning for small teams.
