A monorepo build tool caches task results so you don't rebuild what didn't change, and shares that cache across your team and CI. The tools are free; the shared cache is where pricing shows up.
| Tool | Remote cache | Cache cost | |
|---|---|---|---|
| Turborepo | free, open source | Vercel Remote Cache | free, no usage cap |
| Nx | free, open source | Nx Cloud | free to 500 hrs/mo, then $19/contributor/mo |
| moonrepo | free, MIT | Moonbase | free tier, then ~$10/contributor/mo |
Turborepo is the value winner on cache pricing: Vercel [Remote](/entry/deel-vs-remote-vs-rippling-what-an-employer-of-record-actually-costs) Cache is free with no usage limit, and you don't need to deploy on Vercel to use it. For most teams this gets you ~90% of a monorepo tool's value at zero monthly cost. The limitation is that Turborepo can't distribute task execution across multiple machines — it caches and parallelizes locally, but it won't split your test suite across a runner farm.
Nx does distribute execution. Nx Agents spread tasks across machines, and Nx Cloud adds self-healing CI and optimization insights on top of caching. That's a real advantage at large scale (100+ engineers, long test suites), and it's priced accordingly: free to 500 compute-hours a month, then $19 per contributor. Nx also brings more structure — generators, project graph enforcement, plugin ecosystem — which is either valuable scaffolding or unwanted opinion depending on your team.
moonrepo is the newer, lighter option — MIT-licensed, written in Rust, task-runner-focused without Nx's framework ambitions. Moonbase (hosted cache + CI integration) has a free tier and paid plans around $10/contributor.
Want caching at zero cost and don't need distributed execution: Turborepo. Large team with long pipelines that need distributing: Nx, budget for Nx Cloud. Want a fast, minimal, unopinionated runner: moonrepo.
