# pre.dev

> Autonomous agents for the whole engineering loop: Architect plans, Coding builds, Browser executes.

pre.dev is the self-driving engineering platform. Three autonomous agents cover the full software workflow — **plan, build, and operate** — and you can use any of them standalone or stitched together.

* **[Coding Agent](/coding-agent/overview)** <span style={{ display: 'inline-block', padding: '2px 8px', fontSize: '10px', fontWeight: 600, letterSpacing: '0.05em', textTransform: 'uppercase', borderRadius: '4px', background: 'linear-gradient(90deg, #f59e0b, #ef4444)', color: '#fff', verticalAlign: 'middle', marginLeft: '4px' }}>Flagship</span> Point it at a prompt, a repo, or a template; it ships real pull requests, wires up real integrations, and deploys a working app. Not scaffolding. Not demos.
* **[Browser Agents](/browser-agents/overview)** <span style={{ display: 'inline-block', padding: '2px 8px', fontSize: '10px', fontWeight: 600, letterSpacing: '0.05em', textTransform: 'uppercase', borderRadius: '4px', background: '#10b981', color: '#fff', verticalAlign: 'middle', marginLeft: '4px' }}>New</span> — one REST call (or one MCP tool) to run browser tasks: scrape authed dashboards, fill forms, click through multi-step flows, extract structured JSON.
* **[Architect Agent](/architect-agent/overview)** — pre.dev's planning brain as a standalone API and MCP server. Drop `fast_spec` / `deep_spec` into Cursor, Claude Code, or your own tooling and your agent suddenly plans like a senior architect.

Every surface is API-first, priced per result, and built for humans and agents to share.

  <Card title="Coding Agent" icon="rocket" href="/coding-agent/overview">
    <span style={{ float: 'right', padding: '2px 8px', fontSize: '10px', fontWeight: 600, letterSpacing: '0.05em', textTransform: 'uppercase', borderRadius: '4px', background: 'linear-gradient(90deg, #f59e0b, #ef4444)', color: '#fff' }}>Flagship</span>

    **Ship entire applications from a prompt.** Real PRs, verified acceptance criteria, live integrations, production deploys. Use the web app or plug it into your GitHub workflow.

    **Browser automation that behaves like an API.** Sync, async, or SSE-streamed. Structured data out, not raw HTML. Free tier to start.
  </Card>

  <Card title="Architect Agent" icon="compass" href="/architect-agent/overview">
    **Give any coding agent a senior architect's brain.** One `POST /fast-spec` or `/deep-spec` returns a full structured plan — tech stack, milestones, user stories, granular subtasks. Also available as an MCP server.
