Rustwright uses 70% less memory and starts 2.55× faster
Rustwright is a ground-up rewrite of the tool in Rust. In Skyvern's internal measurements, it used 70% less memory than 's Node.js driver and was 2.55 times faster to get ready.
for Python sends every command through a separate Node.js driver, which then controls Chrome through CDP. Rustwright places a Rust core inside the program and sends CDP commands straight to Chrome, removing that middle process.
Skyvern built it after tuning across many identified the driver as a source of wasted memory and processing work. It began as an internal library and is now available for anyone to use and modify.
Key points
- It used 70% less memory than 's Node.js driver in Skyvern's measurements.
- It was 2.55 times faster to get ready.
- It controls Chrome directly through CDP instead of using a separate Node.js process.
- It was created to reduce wasted memory and processing work in large workloads.
- It started as an internal tool and is now available for anyone to use and change.
