what linea is
one terminal. many agents running at once. none of them lose the thread.
a macOS terminal for engineers who run claude code and codex side by side — every agent in its own branch, every diff under your thumb.
running one agent is easy.
run five and it all scatters — you switch, you re-explain, you burn tokens reminding each one what it already knew.
five agents. five threads. all slipping at once.
so linea gives every agent its own space.
each one runs in its own workspace. always there, always warm.
each on its own branch. 1.2.0 · 1.1.5 · marketing
idle or working — you read every agent's state in a glance.
you come back and pick up clean. no re-explaining. no tokens wasted.
the context holds. the thread never snaps.
then there's what they actually change.
which files. which branch. which worktree.
miss that and you're steering blind.
so linea puts every change in front of you.
every worktree, lined up.
each with its PR. #27 → release/1.1.5
the exact count. +41 −5
and the real diff, side by side, in a native editor.
and reviewing it never breaks your flow.
pull up every agent — ⌘B
jump to the files they touched — ⌘⇧E
ride the diff with the arrow keys.
fix it inline, commit, keep moving. hands never leave the keyboard.
the plan, the diagram, the code — same place.
your agent writes it up — a roadmap, an architecture note.
linea renders the markdown right where you work.
the diagrams draw themselves. inline. mermaid
no other app. no copy-paste. you just read it.
you see what every agent touched — and you catch it before it drifts.
i'm one dev. i built linea because i was tired of running five agents and losing the thread on all of them.
the terminal should move how we move now — many agents, many branches, you on every change.
so i made the one i wanted to use.
every agent, one terminal. take the wheel.
