Nx Agents Turned Our 40-Minute CI Into an 8-Minute One
Jun 2026
How Nx Agents distribute a monorepo's task graph across multiple machines automatically, and why that change cut our CI pipeline from 40 minutes to 8.
Not an exaggeration. Here's what actually happened.
Before Nx Agents, every push triggered a single CI runner that executed tasks one by one. Build. Then test, lint and later E2E. On a monorepo with 10+ apps — that's a queue, not a pipeline.
What Nx Agents actually do:
Nx analyses your full task graph upfront, then distributes the work across multiple agents automatically. No manual parallelisation config. No splitting scripts by hand. You declare how many agents you want — Nx figures out the rest.
Combine that with nx affected (skip untouched projects) and Nx Cloud remote cache (replay instead of rebuild) — and the numbers become hard to ignore:
40 min → 22 min → 14 min → 8 min
Each step in that chain costs almost nothing to set up.
Why this matters for your team:
Fast CI isn't just a developer comfort feature. It's a feedback loop. The shorter it is, the faster you catch bugs, the more confidently you merge, the less context-switching happens while you wait.
Slow CI is a hidden tax on every engineer on the team.
What does your current CI time look like on a monorepo? Curious how much room there is to cut it.
