Labs

One launcher, a lab for every part of your stack

The same hands-on scenario format across your stack — rillence <tool>. PostgreSQL, MySQL, MongoDB and Redis are all available today, each with its own scenario catalog.

PostgreSQL

Slow queries, locks, replication, WAL, storage, vacuum, HA and migrations.

rillence postgres

MySQL

Indexing, connections & threads, ProxySQL, replication and binlog.

rillence mysql

MongoDB

Compound indexes, aggregation pipelines and connection pools.

rillence mongodb

Redis

TTL hygiene, eviction storms, big keys and commands that block the event loop.

rillence redis

What it is

Realistic resilience training, not videos or quizzes

Rillence is a resilience simulator. Boot a real system in a sandbox, break it with a realistic failure, investigate with your own tools, and get deterministic feedback — with zero production risk.

Real sandboxes, real systems

Every scenario boots an actual system in a container — PostgreSQL, MySQL, MongoDB or Redis — not a multiple-choice quiz or a video.

Real-world scenarios

Missing indexes, lock contention, replication lag, eviction storms, connection-pool exhaustion, disk pressure and more — injected into a live system.

AI tutor + deterministic scoring

Get progressive hints while you investigate, a scorecard for your fix and a postmortem explaining the root cause.

Built for individuals and teams

Practice alone, onboard new engineers, or run repeatable team drills across your whole stack.

How practice works

From paged to postmortem in four steps

Launch a lab

Run rillence postgres (or another tool) to open the interactive REPL.

Start a scenario

Pick from a deep catalog of realistic scenarios across production tracks.

Investigate

Connect with your usual client — psql, mysql, mongosh, redis-cli — or an IDE, and dig into the sandbox.

Submit and score

Get deterministic Detect / Fix / Trap scoring and a postmortem.

Scenario catalog

PostgreSQL scenarios across production tracks — plus MySQL, MongoDB and Redis

The PostgreSQL catalog is the deepest: slow queries, locks, connection storms, replication lag, backup failures, unsafe failovers, migrations, security mistakes, and compound incidents. MySQL, MongoDB and Redis ship with their own full catalogs too.

Pricing

Simple pricing for resilience practice across your stack

One subscription covers every lab. Higher tiers add team drills, analytics and management — not more scenarios.

Individual

For a single engineer practising resilience skill solo.

Team

For one team training together — shared drills, scores and readiness.

Enterprise

For larger teams with procurement, training, or deployment requirements.
