VisitGremlin vs Tumult
What both publish
| Fact | Gremlin | Tumult |
|---|---|---|
| Fault injection | Experiments can target services, hosts, containers and serverless workloads, with automatic halt and rollback controls. | The site lists 16 plugins and 91 chaos actions covering technologies including Kubernetes, Docker, PostgreSQL, MySQL, Redis, Kafka, SSH, and CPU, memory, and I/O stress. |
| 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. | Tumult is open source under the Apache-2.0 license. |
| Purpose | Gremlin helps engineering teams find failure modes, fix them, and validate reliability before failures become outages. | Tumult is a Rust-native chaos engineering platform for defining, running, and analyzing experiments that test how systems behave under failure conditions. |
| Security | Gremlin states it is SOC 2 Type II certified and encrypts data in transit with TLS and at rest with AES-256. | The production deployment guide says HTTP exposure beyond loopback requires authentication and documents TLS configuration for the analytics daemon's HTTP and gRPC listeners. |

Pick Gremlin if…
Gremlin is aimed at SRE and platform teams, including teams in financial services, retail, media, and B2B SaaS. It also suits teams that need self-hosting rather than SaaS.
Pick Tumult if…
Tumult suits teams running resilience experiments who need approval gates, audit records and telemetry analysis. It is self-hosted, so users should be prepared to deploy it in their own environment.
