Toxiproxy FAQ
Common questions about Toxiproxy, answered from independent, dated evidence.
What is Toxiproxy?
A Go-based TCP proxy tool designed for testing and CI environments that injects controlled network failures, latency, and corruption to verify applications handle degraded connectivity gracefully. Enables developers to simulate chaos deterministically or with randomization during testing. It is indexed under Chaos Engineering.

The vioscaleAI score: one lens on the evidence
Not user reviews and not a paid placement: a confidence-weighted blend of the independent signals below (adoption, activity, security posture, and more), which you can sort and re-weight yourself. Vendors can correct their listing but can never move their rank, and stars are weighted low as a vanity metric. It is one way to read the evidence for Toxiproxy, not the verdict.
