Debugging modern applications is still surprisingly painful.
Whether you're building a Python data pipeline, a Node.js microservice, or a Go API, debugging usually boils down to two tedious options:
Littering your codebase with console.log() / print() statements and re-running everything.
Stepping forward line-by-line in a traditional debugger, accidentally skipping past the exact mutation that caused the crash, and having to restart from scratch.
To solve this fundamentally, I built Rewind: an open-source, zero-dependency Universal Time-Travel Debugger with sub-microsecond state diffing and an interactive in-browser hot-code patcher.
