Solution — PostgreSQL

Build PostgreSQL Apps Without Writing Boilerplate

Connect your PostgreSQL database and build CRUD apps, internal tools and data management interfaces with forms, relationships, search and role-based access control. The data stays in your database — the platform generates the working software around it.

How it works

From PostgreSQL database to working app in four steps

No ETL pipeline, no replication layer, no data migration. The platform works directly against your live PostgreSQL database.

Connect your PostgreSQL database

Enter host, port (default 5432), username, password and database name — or paste a connection string like postgresql://user:pass@host:5432/dbname. SSL is supported. Credentials are encrypted with AES-256 at rest and only your apps can use them at runtime.

Create or import your schema

Point the visual wizard at existing tables and it picks up your structure, or create new tables from scratch. Field types map to PostgreSQL-native columns — SERIAL, UUID, JSONB, BYTEA, TIMESTAMPTZ and more — so the schema stays idiomatic Postgres, not a proprietary dialect.

Wire up relationships and rules

Foreign keys are detected automatically. Configure one-to-many and many-to-many relationships, dependent dropdowns, field defaults, and context filters that scope rows per user — for example, each employee only sees their own records.

Configure interfaces and roles, then deploy

CRUD screens — list, create, edit, view, delete — are generated for each table. Choose which fields to show, add search and column filters, assign role-based permissions, and publish the app to web, Android and iOS.

PostgreSQL, put to work

Everything between your tables and your users

🐘

Your existing database, live

Connect directly to your PostgreSQL server — production or staging. The platform reads and writes your actual tables in real time: no ETL, no replication, no proprietary storage layer to maintain.

🧩

Visual schema builder

Create tables and fields through the wizard instead of writing DDL. Types map to PostgreSQL-native columns — SERIAL, UUID, JSONB, TIMESTAMPTZ, BYTEA — and the platform detects schema drift with clear, actionable errors instead of silent failures.

🔗

Foreign keys & relationships

Existing foreign keys are detected automatically. Model one-to-many and many-to-many relationships, show related records inline in list views, jump between parent and child records, and build dependent dropdowns from linked tables.

📋

Generated CRUD interfaces

Every table gets list, create, edit, view and delete screens — with column ordering, print-friendly views, and per-table control over which fields appear and where. Add a table, get a working interface; remove a field, the forms follow.

🔎

Forms, search & filters

Forms are generated from your schema with validation built in. Every list view includes search, sorting and per-column filters. Context filters scope rows automatically per user — each person sees only the data they are allowed to see.

🔐

Role-based access control

Define roles and grant per-table permissions: who can view, create, edit or delete. Restrict fields per role, add organization users freely — the platform charges for the platform, not per seat.

Where your PostgreSQL database can live

Any PostgreSQL server you can reach

Standard host, port, credentials and SSL — plus provider-specific guidance built into the connection form. Connecting external databases is available from the Professional plan.

⚡

Supabase

Serverless Postgres with a free tier. Use the Session Pooler or Transaction Pooler hostname from Project Settings → Connect (the free direct host is IPv6-only).

💠

Neon

Serverless, autoscaling Postgres. Enter the full project hostname from your dashboard — the platform handles the rest.

🛡️

Aiven for PostgreSQL

Managed cloud Postgres. Copy the connection details and CA certificate from the Aiven console; the form walks you through it.

🚄

Railway

Enable Public Networking on your PostgreSQL service and use the generated hostname, port and PGPASSWORD variable.

☁️

AWS RDS & Azure

Amazon RDS for PostgreSQL and Azure Database for PostgreSQL connect with standard host, port, credentials and SSL.

🖥️

Self-hosted

Your own VPS, homelab or existing hosting with PostgreSQL. Keep it secure: SSL, strong credentials, or a read-only database user for reporting apps.

Your database. Your rules. No lock-in.

The interface layer sits on top of your PostgreSQL database — it never copies your data somewhere else.

✓

Export your data any time, any way

Your data stays in PostgreSQL. Back it up with pg_dump, pgBackRest, your cloud provider's native tooling, or a plain nightly cron job. No export fees, no permission requests, no format to decode.

✓

Credentials encrypted at rest

Connection credentials are encrypted with AES-256 before storage and decrypted only at runtime for your own apps. A read-only database user is a good fit for apps that only report on the data.

✓

Separate staging from production

Connect up to 12 databases per account. Point a staging app at your staging schema, a production app at production, or split different business units into different databases — all from one team workspace.

✓

Schema drift, surfaced early

If a table in your database drifts out of sync with what your apps expect, you get an immediate, actionable error — not a broken screen and not a silent failure. Fix it in the interface editor and move on.

One configuration, every device

Ship the same app to web, Android and iOS

🌐

Web

A responsive web app your whole team can open in a browser — office, home, or on the go. No installs, no app-store approval needed to start.

🤖

Android

Field teams use the same app — same data, same permissions — natively on Android. Record details, update inventory, and keep working off the office.

🍎

iOS (pending approval)

The iOS companion is pending App Store approval. Web and Android access are available today across all plans.

Building a PostgreSQL app the traditional way — or the fast way

The database work is the same. The amount of application code around it is not.

Task	Custom build	lowcodeapps.dev + PostgreSQL
Time to first usable interface	Weeks of boilerplate	Minutes after connecting your database
CRUD screens per table	Hand-written forms, routes, validation	Generated automatically for every table
Relationships & related records	Custom joins and nested forms	Configure foreign keys in the interface editor
Search, filters & sorting	Query code written per screen	Built into every list view
Role-based permissions	Middleware and guards you maintain	Per-role, per-table access control
Mobile (Android / iOS)	A second app to build and maintain	Same app on web, Android and iOS
Schema change cost	Code change and redeploy	Update the table — the interface follows

PostgreSQL, answered

No. The platform connects to your live database and works with the tables as they are — no ETL pipeline, no replication, no export/import cycle. Existing foreign keys are detected and can be wired into interfaces directly.

Any PostgreSQL server you can reach over the network: self-hosted, VPS, Supabase, Neon, Aiven, Railway, AWS RDS or Azure Database for PostgreSQL. You provide host, port (default 5432), username, password and database name — or paste a postgresql:// connection string. SSL is supported, and connecting external databases is available from the Professional plan.

Yes. On the free tier, use the Session Pooler hostname (port 5432) or Transaction Pooler (port 6543) from your Supabase dashboard — Project Settings → Connect — because the direct host is IPv6-only and not reachable from all servers. Alternatively, add Supabase's IPv4 add-on to use the direct host. The connection form shows these instructions automatically when you enter a Supabase host.

Platform-hosted databases on lowcodeapps.dev are MySQL. For PostgreSQL you bring your own — a free Supabase or Neon project is a quick way to start, or use your existing server. You can connect up to 12 databases per account, and credentials are stored encrypted with AES-256.

Yes, at two levels. Role-based access control controls which tables each role can view, create, edit or delete — and which fields appear. Context filters then scope the rows: for example, a salesperson sees only their own customers, while a manager sees the whole team.

The platform is the single source of truth for your app's schema. If a table drifts out of sync — a column renamed, a type changed — you get an immediate, actionable error rather than a silent failure. Resync through the interface editor and the interfaces follow.

No. Your data never leaves your PostgreSQL database — the platform reads and writes it through your connection. Leave any time: pg_dump your data, or point a new application at the same tables. No export fees, no proprietary format.
