GPT-Migrate - Easily migrate your codebase from one language to another | Produc...

Hey! Josh here, maker of GPT-Migrate. Thank you for taking the time to check out the project!

Code migration is a painful and arduous task. A couple weeks ago, I had to do a migration for another project I’ve been hacking on. It took a few long days, but as I migrated, tested, and debugged function after function, I started to realize that this process could be largely, if not fully, handled with today’s most powerful LLMs.

Last week at a hackathon, GPT-Migrate was born. It works by creating a standardized environment (Docker), translating the code of the source project to the target language/framework, creating unit tests against the source project, testing the newly generated codebase against these, and iteratively debugging based on the error messages and logs.

The most common question I hear is, “does it work with language x to language y?” My answer is: “try it!” Usually the tool will create *something* useful, even if it isn’t totally correct the first time (and with human help, it can cross the finish line).

I’d encourage you to give it a shot with a codebase that you have, even if just for fun! I’d recommend using GPT-4 32k if you do. Smaller models can work but sometimes the input size can be too large. We’re currently working on an improvement here.

What’s next? There are a few “boring” improvements we’ll be making, such as creating more robust unit tests, better and more benchmarks, support for more LLMs, etc. There are also a few exciting things on the horizon that you’ll need to stay tuned to hear about! (Did someone say no more devops? 👀)

Finally, I’d like to thank Ryan Hoover for encouraging me to launch this on Product Hunt, and especially Chris Messina for hunting it!! It wouldn’t have happened without you.

Cheers and happy migrating!

Congratulations on launching GPT-Migrate, Josh!

This sounds like a great tool for streamlining the code migration process. I'm curious, how does the tool handle more complex codebases with a large number of functions and dependencies? Does it have any limitations in terms of the size or complexity of the codebase it can handle?
