The agentic coding IDE

Your agents do the work.
You make the calls.

Build runs your coding agents and surfaces only what needs your judgment — plans to approve, diffs to review, blockers to clear. Everything else keeps moving without you.

One surface for the whole loop

Not a chat window bolted onto an editor. Build is the place where agent work becomes shippable work.

◱

Issue tracking

Tasks are the unit of work, not channels. File an issue, hand it to an agent, and it shows up in your inbox only when it needs you.

⎇

Version control

Git-native from the ground up. Every task gets its own worktree and branch — agents commit as they go, and nothing touches main without you.

⌕

Review

Plan and diff, side by side. See what the agent intended, what it actually changed, and approve or push back in one place.

Dynamic workflows

RLM-driven orchestration: fan work out across agents, verify adversarially, and loop until it's done — not until a script says stop.

Bring your own agents

Build runs full terminal sessions — real PTYs, no SDK lock-in. If it runs in a terminal, it runs in Build.

Enforcement by observation

Build doesn't sandbox your agents into uselessness. It makes everything they do legible — and keeps you at the trigger.

File the task

Describe the work once. Build spins up a worktree and puts an agent on it.

Agents run

Plans, commits, and test runs stream in the background. The terminal is always one keystroke away.

You review

Your inbox holds only the decisions: plans to approve, diffs to review, blockers to clear.

Ship it

Approve and merge. The worktree cleans itself up. Next task's already running.

Stop babysitting terminals.

Your agents are ready to work. Give them somewhere to report.
