While Cursor can write tests, it requires a lot of manual prompting and context juggling to get everything working. You still have to spin up services, manage dependencies, and keep tests up to date yourself.Kerno takes all that testing hassle off your plate, handling everything automatically.It handles setup, data seeding, and dependency orchestration automatically. It writes, runs, and maintains your integration tests as your code evolves, adding new ones when features change and retiring outdated ones when they’re no longer relevant.It runs tests in parallel for fast feedback, self-heals when failures occur, and keeps your suite consistent across the entire team without any manual effort.
Kerno supports all backend programming languages, with the most robust performance for popular ones like Python, JavaScript, Java, and Ruby. Because our AI is trained on public data, its expertise might vary between languages based on their popularity and the public availability of training data.
Your code's privacy is our top priority. It is never stored on our systems and is permanently deleted the moment your test is complete. During the test, your code runs in a secure, completely isolated environment, making it inaccessible to anyone, including our own team, and have 0 day retention policies with our llm providers ( OpenAI and Anthropic).
We only use public data to train our system. Your private code is strictly off-limits and will never be used for training purposes.
Kerno offers free usage for qualified Open Source Projects and a significant discounts for pre-Series A startups. Drop us a note to check your availability.
