AI agents that build software

Describe it.
Agents build it.

Multi-model AI orchestration for complex engineering tasks. An architect plans, specialist workers execute in parallel, you watch it happen in real-time.

How it works

1

Describe your goal

"Build a REST API for managing invoices with Stripe integration, PDF generation, and email notifications."

2

Architect decomposes

Fable 5 analyses the goal, proposes a DAG of parallel tasks with the right model for each.

3

Workers execute

Specialist agents run in parallel, each using the optimal model.

4

Review and ship

Live progress, chat with the architect mid-flight, git checkpoints, iterate.

Everything you need to build with AI

A complete platform for AI-powered software development.

Mission Control

The architect decomposes your goal into parallel tasks and streams live progress as workers execute.

Multi-Model Agents

Fable 5 for hard reasoning, Sonnet 5 for general work, Haiku 4.5 for sub-tasks, DeepSeek V4 Flash for cost.

Research Engine

Parallel search agents plus synthesis with citations.

Visual Workflow Canvas

Drag-and-drop pipelines, export as JSON.

Live Chat with the Architect

Adjust strategy mid-flight without restarting the mission.

Real-Time Progress

Firestore-powered live updates — no polling.
