I built a time-travel debugger for JS/TS.

It works really well especially in serverless contexts (think Lambda, CloudFlare workers, etc. where there's a web-based version of VSCode).

It provides breakpoints that can cycle backwards and forwards.

My little startup basically has too many good options to run with this in the short-term.

Open-sourcing it doesn't seem that attractive as by its nature this would likely lead to a lot of requests for free integration support. Or (worse) nobody would ever find and use it.

Breakpoints that go forwards and backwards feels super futuristic and it's a shame for it to just rot on the vine.

Curious if anyone has ever sold/licensed some under-commercialized tech?
