Deep runtime-level observability for Node.js applications.
N|Solid Runtime is an open-source, cross-platform JavaScript runtime based on Node.js and developed by NodeSource. It captures detailed performance, security, and diagnostic data directly from the Node.js runtime, giving developers and DevOps teams the runtime evidence they need to diagnose production issues, analyze application performance, identify security risks, and understand application behavior.
N|Solid Runtime is the best way to capture detailed runtime-level observability data for Node.js applications and turn that data into the evidence needed to find, diagnose, and resolve issues faster.
Because observability is built directly into the runtime, N|Solid Runtime captures detailed Node.js signals and diagnostics, including:
- CPU and memory telemetry
- Event loop metrics
- CPU profiles and heap snapshots
- Application performance insights
- Package and security intelligence
- Runtime diagnostics for production troubleshooting
This runtime-level visibility gives developers the evidence they need to understand why an application is failing, slowing down, consuming unexpected resources, or behaving unexpectedly.
N|Solid Runtime powers NodeSource's developer and DevOps tools, bringing deep runtime-level observability into the workflows teams already use.
Observe Node.js performance and security in real time with minimal overhead, investigate issues using runtime evidence, and find, diagnose, and resolve problems faster.
N|Solid Console provides centralized performance and security observability for Node.js applications.
Monitor application health and runtime telemetry in real time, analyze performance, identify security risks, access diagnostics, and investigate issues across your Node.js environments from one place.
N|Solid DevTools bring N|Solid Runtime intelligence directly into developer and AI-assisted workflows through the N|Solid Extension and N|Solid Plugin.
Bring N|Solid Runtime observability directly into your code editor. Explore runtime telemetry, diagnostics, dependency information, performance insights, security data, and AI-assisted workflows without leaving your development environment.
Install the Extension:
Bring N|Solid Runtime capabilities into supported AI coding agent workflows. Give agents access to runtime telemetry, CPU profiles, heap snapshots, vulnerability analysis, dependency audits, benchmarks, and other Node.js diagnostics to investigate and resolve issues using runtime evidence.
Get the Plugin:
N|Solid Runtime is open source and can be used independently. NodeSource also offers N|Solid plans for teams that need centralized observability, collaboration, deployment, and support capabilities.
