Context

AppSheet — Generate a small operational app from a table and a limited rules engine. It currently costs $10/mo.

The core loop is buildable, but a dependable replacement becomes a substantially larger project. For AppSheet, generate a small operational app from a table and a limited rules engine. The hard boundary is google integrations, mobile offline support, governance, and managed sync, plus connectors, runtime reliability, and governance.

This brief describes a focused, single-operator replacement for the part of AppSheet that is genuinely reproducible. It is deliberately narrower than the product it replaces, and it says so in writing. Build the useful core; do not pretend to have rebuilt the rest.

What you are building

Define tables and views, generate a small operational CRUD app with a limited rules engine, connect one approved data source, and deploy it for a small trusted team.

Assemble a working CRUD app from components, forms, and stored records.

A responsive interface with real empty, loading, success, and error states.

Requirements

Functional

Docker.

PostgreSQL.

Self-hosted deploy target.

Data and integrations

API credentials for one selected integration.

Each of these needs a real account, credential, or quota. Set them up before writing feature code.

Non-functional

Accessibility: semantic markup, labelled controls, visible focus, and reduced-motion support.

Security: server-side secrets, validated input, and no credentials in the client bundle.

Reliability: retries with backoff on external calls, and a clear failure state when a provider is down.

Portability: the operator can export their data and leave without losing it.

Implementation brief

Build a personal replacement for AppSheet in an empty repository.

Use Next.js 15, TypeScript, Tailwind CSS, PostgreSQL, Drizzle ORM, and Docker Compose; do not offer alternative stacks.

The core loop is: define tables and views, generate a small operational CRUD app with a limited rules engine, connect one approved data source, and deploy it for a small trusted team.

Make the first run work locally with one documented command.

Store all user data locally by default and make export straightforward.

Put secrets in .env, ship .env.example, and never commit credentials.

Create a schema editor for text, number, boolean, date, enum, and relation fields.

Generate list, detail, create, edit, and kanban views from the schema.

Implement role-based read and write rules for admin and member roles.

Support one REST connector with encrypted credentials and explicit field mapping.

Add an activity log, CSV import or export, backups, and health checks.

Ship Docker Compose with migrations and a seeded example workspace.

Include clear empty, loading, success, and recoverable error states.

Add input validation, safe filenames, and graceful handling of unavailable APIs.

Write focused tests for the core transformation and one end-to-end happy path.

Create a README with setup, architecture, permissions, data location, and backup steps.

Do not add accounts, billing, telemetry, analytics, or a hosted control plane.

Deliberately leave out arbitrary user-authored code execution.

Deliberately leave out a broad integration marketplace.

Deliberately leave out native mobile binaries and enterprise compliance.

Finish by running the tests and listing the exact commands used.

Delivery standard

Inspect the repository first, then write a short implementation plan before writing code.

Deliver the smallest complete end-to-end workflow first; every primary control must work against persisted data.

Use real validation and storage; never substitute fake dashboards, decorative controls, hard-coded success states, or mock integrations.

Include responsive layouts plus genuine empty, loading, success, validation, and failure states.

Keep secrets server-side in environment variables, provide .env.example, and never commit credentials or user data.

Add structured logs around every external call and return actionable errors without leaking sensitive details.

Write unit tests for the core logic and one automated test of the main user journey.

Finish with a README covering setup, architecture, data location, backups, tests, deployment, and known limitations.

Acceptance criteria

A clean install starts the app using only the README and .env.example.

The primary journey works from first visit through saved result, reload, edit, export, and deletion where applicable.

Invalid input, missing configuration, provider failure, and an empty database each have a usable state.

The interface works at 390px and 1440px, is keyboard navigable, and shows visible focus on every control.

Tests, type checking, linting, and a production build all pass with no ignored failures.

No part of the interface implies a live integration, security guarantee, or scale capability that was not actually built and verified.

Non-goals

Do not build these, and do not claim to have replaced them:

Google integrations, mobile offline support, governance, and managed sync.

Hundreds of connectors.

Pixel-perfect app design.

Mobile app-store builds.

Enterprise permissions and scale.

What you still own after launch

Secure credentials, rotate secrets, and handle provider rate limits.

Run migrations, backups, restores, and dependency updates.

Test the critical journey after every model, API, or hosting change.

Monitor failures and fix the edge cases a first prompt will miss.

Maintain every third-party integration as APIs and OAuth rules change.

Risk

Operational risk. The code is achievable; dependable data, integrations, and ongoing operations are the real cost.

Editorial confidence in this assessment: medium. No reviewed project implementation is linked yet.

Existing alternatives

Before building, compare these checked options:

Baserow Free — Tables become forms, pages, views, automations, and a small role-aware app without writing code

Budibase — Internal apps, forms, automations, and portals in one box; much closer to Knack than its developer branding suggests

Joget Community Edition — Forms, lists, workflows, and role-aware apps from a product old enough to have survived several no-code fashions

Prior art

Working open-source software you can read, fork, or borrow from before starting:

Appsmith — Large open-source low-code platform for internal applications and data sources
