Liner Code in dark mode, at work on Fix the tide time after midnight: Sonnet 5.5 on a second turn with two helper agents exploring the code, the Reviewer's Verified verdict on the first, and the Changes panel open on src/tides.js, three lines added and one removed.

It runs Claude Code, Codex, OpenCode and Hermes with your own sign-ins, and shows their work as plans you approve and questions you answer.

Everything around the session

One turn, from ask to diff

Ask in plain words. It asks before it guesses, plans, builds, and hands you a diff to keep or undo.

The tide fix in Liner Code: the Demo's plan, its edit and test, and the Diff panel beside it with src/tides.js, Undo turn 1 and Commit 1 file.

Surfaces beside the session

The Browser, Design, Terminal, Files and the rest open next to the conversation, each one key away.

The tide fix session with its panel open on the New tab guide: Session, Side chat, Browser, Design, Terminal, Files, Changes, Pull request and the rest, each with its key, and Changes, Files and Browser as tabs above.

The Desk

Sessions sort themselves by what they need from you. Press what waits, and one press decides.

Home with the Desk open: the tide fix back with you with one file to review, and the tide screen design done.

Designs

Any agent draws the screen beside the session. Point at a part to change it, then Build it.

A session that asked for a home screen for the tide tables, with the Design surface beside it showing the phone screen.

Solo, Plan, Auto

Pick how a session works. A model from another maker checks each change before it's yours.

Settings, Agentic features: Solo, Plan then build and Auto, each with the models it uses.

Add-ons, made in Workshop

Ask for what Liner Code doesn't have, and an agent makes it. Nothing goes in until you say yes. About Workshop

Nothing in between

No server, no telemetry. Sign-ins stay with each tool, keys stay in your Mac's keychain, and model traffic goes straight to each provider.

Auto gives each message the least work it needs.

Heavy jobA hard job

    This is route.ts from Liner Code, running in your browser. In the app it runs on your Mac with no model call, so it costs nothing and sends nothing anywhere.

    Shown with Claude Code, Codex and OpenCode Go signed in: DeepSeek V4.1 Flash takes most messages, Opus 5.5 the hard ones, GPT Astra reads them.
