Lightrun requires no source
code access -
No code, only metadata,
passes through the server -
Lightrun is runtime-based, and runs
where you run at any scale

Choose where you need more visibility: your code, legacy code, 3rd party code – you name it, we instrument it.

Instrument everything in real-time, without stopping the live application: one click in the IDE, and your live app is instrumented in a read-only, secure fashion.


Observe the information immediately: see it right in the IDE or in one of our 30+ observability integrations.
