Dev OS · How it works

One AI engineer. Your whole dev team.

Dev OS is a chat where @devmanager — a single AI that plans, codes, tests and ships — turns plain English into working software. Live preview, browser-tested QA, one-click publish, even your own custom domain.

The Core Concepts

4 things to know before you start.

A Dev OS chat is a chat

Same composer, same members, same notifications. The only difference: it’s linked to a Dev OS project, and the right side of the screen shows a live workspace pane.

@devmanager is the only hire

One AI in the room — it reads every message, plans, codes, runs QA and releases, speaking in first person. No sub-agents to coordinate, no hand-offs to babysit.

The 5-tab Build Room

Chat · Preview · Tasks · Files · Release. Your app updates live in the Preview tab as you talk; the Release tab handles publishing, custom domains and env vars.

Persistent memory

Every agent reply is indexed and tagged by role. Future replies retrieve relevant prior context — your team never re-explains decisions.

Slash Commands

Type the slash. Skip the meeting.

Slash commands work in any chat that has a linked Dev OS project. No project linked? Just tap the 🚀 in the chat header.

/dev-os new <name>

Create a project + link it to this chat. Idempotent — re-running returns the existing project.

/dev-os plan

Print the linked project’s product brief + pillars right in chat.

/dev-os task <title>

Add a backlog task to the linked project’s Kanban board.

/dev-os bug <desc>

File a bug (severity: medium). QA agent reproduces it within SLA.

/dev-os scan

AI scans the last ~30 messages and drafts improvement proposals.

/dev-os help

Show this list inside the chat.

One-command actions & Builders

No code. Just plain English.

Quick actions and guided Builders sit right above the chat box — fill in a sentence and @devmanager wires it into your app.

The Workflow

From idea to live URL in 6 steps.

Spin up a dev chat

New chat → "Development project" — or start from a template with a live demo you can try first.

Tell @devmanager what to build

Plain English — even paste your current website's URL and it imports the content and brand colors.

Watch it build live

A progress card streams every step; the Preview tab shows your working app in ~60 seconds, demo login included.

Iterate in the Build Room

Quick actions (Build App, Fix Bug, Run QA, Improve Design) and guided Builders for rules, roles, data, workflows, forms and reports.

QA gates + browser test

Every build passes security & QA gates plus a real headless-browser check: page loads, demo login works, zero JS errors.

Publish — even on your domain

One click to /p/your-app, or add a CNAME and serve it on your own custom domain. Opt in to the Built with TeamNest showcase.

Credit Pricing

Dev OS bills your workspace in TeamNest credits — simple usage-based pricing on the same top-tier models.
