    Leaping – Debug Python tests instantly with an LLM debugger2024 · github.com · ▲120

    Hi HN! We’re Adrien and Kanav. We met at our previous job, where we spent about a third of our lives combating a constant firehose of bugs. In the hope of reducing this pain for others in the future, we’re working on automating debugging.

    Visual debugger for Rails system tests2024 · github.com · ▲131
