How to check Wu's memory use against your current editor with Wu

Read the memory benchmark and measure your own setup before moving a machine to Wu.

Who it is forA developer on a low-memory laptop deciding whether to switch from VS Code or Zed to Wu.

The problemEditor memory use affects how much room is left for builds, browsers, and other tools, and claims about it are hard to check.

The outcomeYou have your own memory readings for your current editor and for Wu on the same project, so the switch decision rests on your numbers.

What you need first

  • A desktop computer running macOS, Linux, or Windows
  • Permission to install a desktop app
  • Optional: access to Claude Code or Codex for the agent use case

Steps

  1. Open https://github.com/dstrml/wu/blob/main/docs/memory-benchmark.md and note how the benchmark measured memory.
  2. Open your current editor on your project and record its memory use with your operating system's task monitor. (inferred, check the README)
  3. Install Wu using the steps in https://github.com/dstrml/wu/blob/main/docs/INSTALL.md.
  4. Open the same project in Wu and record its memory use under the same conditions.
  5. Compare the two readings and decide whether the difference matters for your work.

Prompt for your agent

Clone the dstrml/wu repo and read docs/memory-benchmark.md. Expected output: a short summary of how the benchmark measured memory and which editors it compared. Verify that the summary names each editor compared.

Caveat. The README says Wu uses less memory than VS Code and Zed and links a benchmark, but this page does not give figures, so check the linked document yourself.
