Production Flask + Next.js from your architecture

Flask is Archiet's default backend. A generated Flask app includes JWT auth with httpOnly cookies, SQLAlchemy models with Alembic migrations, a typed OpenAPI spec, Celery for async tasks, and a multi-stage Dockerfile. The companion Next.js frontend uses App Router + shadcn/ui.

What's in the generated ZIP

Every Flask app generated by Archiet ships with these baseline pieces. No template-cutting, no placeholder TODOs.

JWT auth with httpOnly Secure SameSite=Lax cookies (no localStorage)
SQLAlchemy models + Alembic migrations per entity
Pydantic-style request validation + consistent error envelopes
Celery + Redis for async jobs, Celery Beat for scheduled tasks
OpenAPI 3.1 spec auto-generated from routes
pytest suite with fixtures + factory_boy
Multi-stage Dockerfile + docker-compose for local dev
GitHub Actions CI: lint, test, build, deploy
CLAUDE.md file tuned for Flask to keep AI-coding tools aligned

Sample generated file

One representative file from a generated Flask app. Your generated output will include many more files like this one, customized to the entities and flows in your blueprint.

app/blueprints/auth_bp.py

from flask import Blueprint, jsonify, request
from flask_jwt_extended import create_access_token, set_access_cookies

auth_bp = Blueprint("auth", __name__)

@auth_bp.route("/login", methods=["POST"])
def login():
    body = request.get_json(force=True) or {}
    user = User.query.filter_by(email=body["email"]).first()
    if not user or not user.verify_password(body["password"]):
        return jsonify({"error": "invalid_credentials"}), 401
    token = create_access_token(identity=user.id)
    resp = jsonify({"data": user.to_dict()})
    set_access_cookies(resp, token)
    return resp
