This is how an agentic monorepo looks like. What was now a hurdle before is now a child's toy
This side project started as a Python project earlier in 2025
Then I added an iOS app on top of it
I rewrote the most important algorithms in Rust
I rewrote the entire backend in Go and retired Python to be used purely for prototypes
I wrote a webapp with Next.js
With unit and integration tests for each component
Lately written 99% by instructing agents
Crazy mixed language programming going on in the background. Rust component used both by iOS app for offline and by go backend for online use case, FFI and all
Number of lines in the repo: a couple 100k
If you had told me I would be able do to all of this by myself 1 year ago, I would not have believed it
This is huge. Natively supported stacked PRs on GitHub would make life much easier, especially with human AND AI reviews
AI reviews with Codex/Claude/Gemini/Cursor Bugbot integrations are becoming especially important in small teams who are generating huge amounts of code
AI reviews don't work well if you don't split your work to diffs smaller than a few hundred lines of code, so stacked PRs are already an integral part of developer experience in agentic workflows
