A software factory for your backlog
From plan to finished, tested code, agents run every issue through the same SDLC workflow, with your engineers in the loop
[Problem]
Your team adopted agents, not a process
Agents make the decisions
A short prompt leaves the choices to the agent, and by code review it’s too late
Agents grade their own work
Your coding agent writes its own tests, so they share its blind spots
Review is now the bottleneck
Agents open pull requests faster than your senior engineers can check them
[How it works]
Every issue takes the same four steps
[01]
Assign an issue
Hand it to an agent the way you would a teammate, and it asks questions on the issue if anything is unclear
In your issue tracker
Assignee
Unassignedbuild.dev[02]
Approve the plan
Your engineers review an agent’s plan before any code exists, so a misunderstanding costs a comment instead of a rebuilt branch
In your repo
[03]
Agents build and test it
One agent builds from the approved plan, and another tests the running software against scenarios the builder never sees
In a sandbox

[04]
Merge the pull request
It reaches your team only after CI and AI code review pass, and agents make any changes you request
In your repo
[Inside the factory]
The parts you’d otherwise build and maintain
[Independent testing]
Tested independently before review
A separate test agent tries the running app like your customers would, so the build agent never grades its own work
[Sandboxes]
Every issue runs in its own sandbox
Agents get an isolated cloud environment with your app running inside, where they can install, run, and break things without touching anything else
[Memory]
Agents map out your codebase as they work
What they learn on each issue goes into a knowledge graph of your code, so the map gets more detailed over time
[Continuous improvement]
The longer it runs, the faster and cheaper it gets
Every issue runs the same workflow, so the factory can tell what worked and do more of it
[Integrations]
Agents connect to the tools your team already uses
MCP connections bring your designs, docs, and production errors into every plan and build
[Analytics]
Measured like a production line
Output and cost are tracked on every issue, from assignment to merge
[FAQ]
How it fits your team
How is this different from the coding agents we already use?
Coding agents work for one developer at a time, and that developer owns the process. build.dev is a workflow your whole team takes part in, through the issue tracker and repo you already use
Does it replace our engineers?
No. Your engineers approve every plan and review every pull request, and agents do the work in between
What can we customize?
You can customize the agents to fit how your team works. The workflow itself is fixed, so there’s nothing to design or maintain
