Support engineers
learn by doing.
Real sandbox environments to learn debugging APIs, diagnosing email deliverability, troubleshooting networks, and handling live customer scenarios - all in one platform.

How it works
The method behind the platform
Three types of practice, each targeting a different skill layer.
01
Diagnose
Work through a problem in the sandbox. The error is real, the API client is real, and every request has consequences. Score is based on how efficiently you find the root cause.
02
Communicate
Turn on the communication toggle and write a response to the customer. System scores your message on technical accuracy, empathy, and whether you told them exactly what to do.
03
Simulate
Different real life support scenarios with virtual customers. Test your problem solving, communication and escalation management skills in a time-bound live simulation.
Features
Everything a support engineer needs to improve
Debug real API issues
Engineers work through actual API request failures, rate limit errors, Oauth errors and webhook misconfigurations using a live API client. Every request, every response, every header - exactly like production.
Practice difficult customer conversations
Role-play as a support engineer handling a frustrated customer whose integration is broken. System evaluates your empathy, technical accuracy, and resolution clarity after every session.
Diagnose SPF, DKIM, and DMARC problems
Paste raw email headers and get a structured analysis: authentication results, spam score, alignment checks, and specific DNS fixes. Includes a live DNS record checker for every email record type.
Run real diagnostic commands in a safe environment
A full terminal emulator where engineers run ping, traceroute, dig, curl, openssl, and nmap against realistic failure scenarios - firewall blocks, SSL mismatches, routing loops.
Know exactly where each engineer needs help
Managers see team progress, individual skill gaps, assignment completion, and simulation scores. Engineers get coaching tips extracted from their own evaluation data.
Points, badges, and leaderboards
A scoring system that rewards efficiency and quality, not just completion. Badges unlock at meaningful milestones. A team leaderboard drives healthy competition without ranking beginners against veterans.
For individuals
Advance your career as a support engineer
Get hands-on with the exact problems that come up in technical support interviews and day-to-day work. Build your portfolio of solved scenarios. Track your improvement over time with detailed reports.
- Practice at your own pace
- Scored on efficiency, not just correctness
- Earn badges that signal real skill
- Compare progress on the leaderboard
For teams
Onboard faster. Train smarter. Hire better.
Assign problems and simulations to new hires. See exactly where each person is struggling before they handle a real customer. Use the assessment flow to evaluate candidates before an interview.
- Assign problems, simulations, and courses
- Manager dashboard with team progress
- Automated notifications on assignments
- Pre-hire assessment reports
FAQ
Common questions
How is this different from a generic learning platform like Udemy?+
Support Lab is leetcode for support engineers. Every problem, simulation, and sandbox is drawn from real support tickets. Everything is hands-on in an environment that mimics what you actually do at work. We emphasize on learning by doing.
What technical background do I need?+
We do offer courses for people who do not have a technical background. Our goal is to help people learn by solving problems irrespective of their background. Problems have difficulty levels defined to cater to beginners vs experienced engineers.
Can I use this for hiring assessment?+
Yes. The Team plan supports pre-hire assessments. Generate an invite link for a candidate, assign specific problems and a simulation, and get a shareable score report. The report shows their diagnostic approach, not just whether they got the right answer.
How does the simulation evaluation work?+
After each simulation, the system evaluates your response across multiple criteria: technical accuracy, communication clarity, empathy, escalation judgment, and resolution completeness. You get a score, criterion-by-criterion feedback, and a coaching tip.
