VisitGremlin vs Toxiproxy
What both publish
| Fact | Gremlin | Toxiproxy |
|---|---|---|
| API | The public REST API uses the base URL https://api.gremlin.com/v1 and has an OpenAPI specification. | The HTTP API supports creating, updating, listing, and deleting proxies and toxics, resetting proxies, and retrieving version and Prometheus-compatible metrics. |
| Intended users | Gremlin describes its users as SRE and platform teams, and says financial services, retail, media, and B2B SaaS companies use the product. | The project is aimed at developers and teams testing service failure handling in development, unit and integration tests, and CI. |
| License | Gremlin's commercial reliability platform is not offered as an open-source product; a G2 reviewer specifically notes that no open-source version is available. | The GitHub repository identifies the project license as MIT. |
| Purpose | Gremlin helps engineering teams find failure modes, fix them, and validate reliability before failures become outages. | Toxiproxy is a TCP proxy for simulating network and system conditions in chaos and resiliency testing. |
| Security | Gremlin states it is SOC 2 Type II certified and encrypts data in transit with TLS and at rest with AES-256. | The HTTP API is unauthenticated by default and can create proxies to arbitrary upstreams; the project advises against exposing it to untrusted networks and supports bearer token authentication. |
