Dev builds Rust JIT prototype with AI in 2 weeks; Ruff author wants to try it
rikarends · x · 2026-10-25
Makepad author rikarends showcased a Rust JIT prototype his AI built in two weeks, targeting Rust's notoriously slow compile/iterate loop as a proposal for how performance could work—and invited people to attack it with their AIs.
- Running makepad play shows applications being live-JIT'd with an animation.
- It's a deliberate "fork-away" project: not meant to be maintained as everyone's Rust tool, just his own dev JIT for Makepad UI apps.
- Ruff/Astral author charliermarsh replied he wants to try it on his projects; rikarends quipped "PRs are so 2025" and hopes a foundation-backed team AI-mashes the idea into a stable, compiler-engineer-supervised direction.
A notable demo of AI-assisted compiler prototyping drawing attention from top tooling authors.
