Our take

An async, repo-aware coding agent from Google that plans, edits, tests, and opens PRs on its own, powered by Gemini.

Best for

Developers who want to delegate bug fixes, tests, and small features to an agent that runs in the background.

Pros

Works asynchronously in an isolated Google Cloud VM
Reads full repo context, writes a plan, runs tests, opens a PR
Powered by Gemini; out of public beta
Private by default, does not train on your code

Cons

Async model is a mindset shift from inline assistants
Best for scoped tasks, not large ambiguous work
Tied to the Google/Gemini ecosystem

How it compares

Versus GitHub Copilot, Jules is fully asynchronous, taking a whole task and returning a PR rather than completing code inline.

Full review

Jules is Google's asynchronous coding agent: hand it a GitHub issue and it spins up a cloud VM, clones your repo, drafts a plan, implements the change, runs the test suite, and opens a pull request, all in the background.

It is out of public beta and powered by Gemini, and is private by default. It shines on well-scoped tasks like bug fixes, dependency bumps, and small features; large, vague work still benefits from a human in the loop.
