Today I had nine Macs building and testing nine iPhone Duo apps at the same time. I used zero physical Macs.

What's happening now with cloud agents is like early AWS or serverless days. EC2 let you go from one server to a hundred and back. Serverless let you forget servers entirely.

Devin is Lambda for engineering work: you send a task, and an agent plus its computer exist only while the job runs, and if you set your AWS credentials you can run cloud agents there as well (EC2 for builds, GPU boxes for games and ML, all in your account).

In 2006, startups stopped buying servers to run their infrastructure, now we're seeing them no longer needing hardware to even build their software.

Multiplayer engineering with cloud agents is the future, but a lot of teams haven't yet made the leap, so I'll share some reasons why it's objectively better.

1. Progress should not be siloed. A hospital patient chart doesn't belong to just one nurse, instead its an ongoing log of patient info and activity shared between everyone, cloud agents are shared history of a coding session that anyone can see and continue and learn from and chime in on (information shared between team *and* future agent sessions).

2. Expertise should not be siloed. What I find most fascinating today is understanding how other people break problems down, and when they step in. This is essentially why "skills" are interesting to some people. In local sessions almost no one gets to see this, but shared cloud sessions make this observable by default.

3. Handoffs are now one of the most expensive tasks in engineering. This is a relic of a time when friction existed because the person with the requirement couldn't work on the "thing" directly. This world no longer exists, anyone can do anything if they understand how to explain their solution.

4. One source of truth is superior. For instance during an outage a bunch of engineers usually investigate in parallel, each using their own tools / techniques but only their own perspective. If there's a canonical agent session the whole response channel everyone works from the same evidence. *Emergency services organize around a shared picture for exactly this reason.*

5. Disagreements can be verifiable. When people disagree, arguments have been theoretical. Now, they can be objective (spin up parallel agents to build, test, and verify solutions simultaneously).

Cloud agents are better or the same reason that Notion is better for collaborative writing than passing around a local text file. It's obvious when you use them, but maybe not so obvious if you're an engineer from the past era when this type of work was not possible.

Use code DEVIN-TEAMS for 50% off Devin Teams for 3 months if you're planning to migrate to Devin from Conductor (or another coding agent).

A company’s shipping speed is now limited by how much change it can safely verify rather than how much code its agents can generate.

We're making Devin code review and verification better, faster, cheaper, and there is no finish line.
