Pernosco

Fast, fun, omniscient debugging.

Record failures anywhere: locally, QA, CI, or in production

Record your x86 Linux program using rr.
Submit those recordings to Pernosco for processing and Pernosco sends you a link to access the debugger that you can use from anywhere.
Once you've captured a recording (e.g. of an intermittent test failure) you don't need to reproduce the bug again.

Rapidly debug recordings using the revolutionary Pernosco omniscient debugger

Pernosco gives you instant access to the full details of any program state at any point in time.
Pernosco visualizes control flow and data flow history so you can quickly track effects back to causes.
Pernosco transcends the limitations of traditional debugger interfaces; but it also integrates traditional debugging approaches like gdb and printf debugging — enhanced with new superpowers.

Share your recordings and debugging state with other developers

Record your debugging progress in the Pernosco notebook.
Loop in other developers to collaborate.
Or, capture recordings of test failures (e.g. from fuzzing) and send Pernosco links directly to other developers for debugging.

Pernosco currently targets C, C++, Rust, and V8 JS (e.g. node.js) applications that run on x86 Linux and work with rr.

For larger-scale use (e.g. company-wide) we can work with organizations to meet your technology, pricing and business needs (e.g. on-premises deployment). Contact us.
