Ultra Runner

What Ultra Runner is
Ultra Runner is a free Linux monorepo script runner and build tool. It detects Lerna, Yarn, npm 7, and pnpm workspaces, or searches recursively for packages, while working with existing monorepos without package.json changes. Builds use workspace dependencies and file-change tracking to run concurrently and skip packages without detected changes. Recursive commands can run package scripts, node_modules binaries, and system binaries. Ultra Runner parses package.json scripts, supports &&, ;, and || operators, and runs configured pre- and post-scripts. Wildcard filters target package names or subdirectories. Recursive work defaults to concurrency of 10, adjustable with --concurrency. Output modes are pretty, no-pretty, raw, and silent; --monitor lists running Node processes with package and command line. The README provides npm and Yarn installation commands and says npm or Yarn scripts remain usable with optional concurrency settings. The project uses an Apache-2.0 license.
Who it suits
Ultra Runner suits Linux developers managing monorepos with npm, Yarn, pnpm, or Lerna workspaces. It is useful when concurrent, change-aware builds and recursive script execution are needed.
What it does well
- Works without package.json changes
- Detects several workspace formats
- Skips unchanged package builds
- Wildcard filtering targets packages or subdirectories
- Adjustable command concurrency
What to know first
- Linux platform listed
- Default concurrency is limited to 10
- Build cache uses local file tracking
- Interactive stdin commands require raw mode
Verdict
Ultra Runner brings workspace detection, concurrent execution, filtering, and change-aware builds to monorepo scripts. Its Linux listing and local cache scope define the operating context.
