SadServers is a SaaS platform for practicing Linux and DevOps troubleshooting skills on real ephemeral Linux servers in a Capture-the-Flag format, with browser-based SSH access and automated solution checks. It also serves as a hands-on assessment tool for organizations evaluating candidates for Linux, DevOps, and SRE roles.
Use cases
- practice linux troubleshooting on real servers
- prepare for devops or sre interview
- assess candidates for linux sysadmin jobs
- learn to debug broken docker and kubernetes deployments
- hands-on capture the flag challenges for linux
- train incident troubleshooting skills
- run technical interviews with real infra tasks
When to choose
- you want hands-on practice fixing realistic broken Linux servers rather than reading tutorials
- you need to evaluate candidates with practical Linux/DevOps/SRE troubleshooting tasks
- you want CTF-style challenges covering databases, web servers, Docker, and Kubernetes
- you prefer browser-based ephemeral VMs with automated solution verification
When to avoid
- you need a fully self-hosted open-source lab platform - this is a commercial SaaS with no license on the code
- you are looking for passive learning like video courses or multiple-choice quizzes
- you need Windows or macOS troubleshooting practice - scenarios focus on Linux
- you require offline practice without internet access or cloud-provisioned VMs
