How it works

From idea to deployed code in a continuous quality loop

💬
01

You describe

Tell BabyDev what you want — voice or text. A website, an API, a full app.

📋
02

Planner architects

Breaks your idea into user stories, acceptance criteria, architecture, and a task breakdown.

🔨
03

Developer builds

Full-stack implementation — frontend, API, database, infrastructure. Commits every 30 minutes.

🎯
04

Tester validates

Scores the work 0–100 across 5 categories. Below 90? Sent back for fixes. Above 90? Ships.

↩Score below 90? Tester sends it back to Developer. Max 2 throwbacks per task.

Meet the agents

Three specialized agents, each with a clear role and strict boundaries

P

Planner

Client liaison, scope definer, architect

Orchestrator + Product Owner + Planner + Task Manager + Project Manager

  • ›Interprets user requirements
  • ›Writes project briefs & user stories
  • ›Defines acceptance criteria
  • ›Designs system architecture
  • ›Breaks work into tasks
Outputs: Brief, stories, criteria, architecture, task breakdown
⛔ Never writes code
D

Developer

Full-stack builder

Frontend + API + Database + Infrastructure + UI Designer + Auth + Copywriter

  • ›React, Next.js, Three.js, Tailwind
  • ›FastAPI, PostgreSQL, Supabase
  • ›Vercel, Cloudflare, Docker
  • ›10+ MCP servers, 15+ CLIs
  • ›Commits every 30 minutes
Outputs: Complete codebase, README, tests, deployment
⛔ Never deploys without Tester approval
T

Tester

Quality gate, validator

QA + Code Reviewer + Performance Auditor

  • ›Functionality testing (30 pts)
  • ›Code quality review (20 pts)
  • ›Test coverage check (20 pts)
  • ›UI/UX validation (15 pts)
  • ›Performance audit (15 pts)
Outputs: Score card, detailed feedback, pass/fail verdict
⛔ Never fixes code — only scores and sends back
