Breaking software before it breaks your business.
Calvera Solutions tests the systems that hold up under load, under attack, and under change: API contracts, AI-driven pipelines, and the strategy that decides what to test at all. Based in the EU, working with teams anywhere.
Capabilities
Three disciplines, one job: telling you the truth about your software before your users do.
Contracts under pressure
Functional, negative, and boundary coverage across REST and event-driven APIs: schema validation, auth edge cases, and the failure paths teams usually skip.
Learn more →Testing, accelerated by AI
AI-assisted test case generation, self-healing automation that survives UI and API churn, and pattern analysis across logs and failures that manual review would miss.
Learn more →What to test, and why
Risk-based test strategy, coverage analysis, and process audits that tell you where quality actually breaks down, not just where it's easy to check.
Learn more →Book a trip to Saturn. Then count the bugs.
Space Tours is the booking API I teach on. Two versions are live: one that works, and one with bugs planted in it on purpose. Some are obvious, some are not.
Book a seat to Saturn, then see how many you can spot.
Take the challenge →Some bugs you just have to shoot.
Space Tours sells the trip. Somebody still has to fly it. The demo plays itself until you take over.
