Architectural Insight

Using UUIDs prevents enumeration attacks. The check constraint on 'tier' ensures data integrity at the database level, reducing application-side validation errors.

Core Intelligence

Built for the 1%

Senior DBA Reasoning

It doesn't just generate SQL. It explains the tradeoffs between normalization and performance, suggesting indexes where they matter most.

Secure by Default

Your OpenAI API key is stored locally in your browser via localStorage. We never touch your credentials or your data.

Supabase Ready

Copy-paste ready SQL scripts optimized for Supabase's PostgreSQL environment, including Row Level Security (RLS) policies.

Interface Standard

Sage Green Aesthetic. Distraction-free Design.

We believe tools should be calm. Our interface uses a restrained palette designed for long-term productivity and reduced eye strain during late-night debugging sessions.

Context-Aware Suggestions

Understands the difference between OLAP and OLTP requirements.

Bilingual Support

Seamlessly toggle between English and Indonesian for international teams.

Risk Analysis

Highlights potential security risks in your proposed structure automatically.

SECURITY_CORE_V1
Auditing
[CRITICAL] RLS DISABLED

Table 'financials' is publicly readable. High security risk.

[OPTIMIZED] GIN INDEX

Jsonb search performance boosted by 400% via trigram index.

Engine Logic

From Concept to Query

A streamlined workflow for database architects.

01

Describe Requirements

Input your business logic in plain English or Indonesian. "I need a multi-tenant SaaS schema for a project management tool."

02

AI Architectural Review

JoonaMock analyzes requirements against known scalability patterns, identifying potential bottlenecks before code is written.

03

Deploy Schema

Receive a complete SQL file with comments, indexes, and RLS policies. Ready to paste directly into your Supabase SQL editor.

Accessibility

Professional Tools, Democratized

We provide the interface and the prompts. You provide the API key.

Community Edition
$0/forever

Full access to the schema generator, risk analysis, and Supabase optimization tools.

No credit card required. Just your API key.

Validation

Trusted by Developers

"The reasoning engine is what sets JoonaMock apart. It doesn't just give me a table, it tells me *why* I should use a JSONB column instead of a separate table for my specific use case."

"Finally, a tool that respects the 'Sage Green' aesthetic. It feels calm to use. The Supabase RLS generation saved me hours of debugging policies."

"The BYOK model is brilliant. I pay pennies for my own API usage and get a premium tool interface for free. Highly recommended for bootstrapping."

Frequently Asked Questions

Is my OpenAI API Key safe?
Yes. Your key is stored exclusively in your browser's localStorage. It is sent directly to OpenAI's API from your client. It never touches our servers.
Does it work with other databases besides PostgreSQL?
Currently, JoonaMock is hyper-optimized for PostgreSQL and Supabase. We believe in doing one thing perfectly rather than many things poorly.
Is it really free?
The tool interface is free forever. You only pay OpenAI directly for the tokens you consume via your own API key.
