Project mention: Show HN: Unlogged (YC S22) – open-source record and replay for Java | news.ycombinator.com | 2023-10-30

Hello HN! Parth, and Shardul here. We have been building unlogged.io for the last 21 months. We started as a time travel debugger and pivoted to record and replay with assertions, mocking, and code coverage. You can save the replays in the form of a JSON and commit them to your git.

Both Parth and I come from an e-commerce/payments background where production bugs meant heavy financial losses. Big billion days/Black Friday sales meant months of code freezes with low productivity. Before committing the code, we wanted to replay production traffic and know the breaking changes right away, like in sub-second. Kind of like unit+integration tests on steroids.

So, we built an SDK that adds probes to the code in compile time. The SDK logs code execution, in detail.

Git: https://github.com/unloggedio/unlogged-sdk

We also built an IDE plugin that keeps monitoring code changes, hot reloads these changes, replays the relevant methods, and alerts on failing replays. It also lets developers call Java methods directly, mock downstream methods in run time, highlight code coverage in real-time, and show performance numbers for methods with inlay hints. (right above each method)

Git: https://github.com/unloggedio/intellij-java-plugin

We are excited to launch the first version of our product that replays with assertions + mocking + code coverage reports right inside the IDE.
