No-code apps and databases decision

AppSheet

A competent developer can build a useful subset (sheet connectors, generated CRUD UI, and simple automations) given prior open-source projects, but reproducing AppSheet's enterprise integrations, AI-assisted creation, offline/mobile polish, and Workspace bundling is impractical for a small DIY build.

Open-source builds that already do this

Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need — the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship.

What a replacement has to do

Allow a user to point to a spreadsheet, auto-generate CRUD forms and lists, persist changes back to the sheet or a simple DB, and run simple rule-based automations/notifications.

What it still won’t have

Deep Google Workspace bundling and single-sign admin flows
Built-in AI-assisted app generation (Gemini integration)
Enterprise governance, audit logs, and advanced connectors (Apigee, BigQuery, etc.)
Offline/background sync and mobile-first polish
Vendor support and SLAs

Runnable build prompt

Not run yet

Build a minimal no-code app platform in Node.js + React, Postgres for server storage, and OAuth Google sign-in. In scope: (1) connector to read/write Google Sheets and fallback Postgres sync, (2) auto-generate CRUD web UI (list, detail, form) from table schema, (3) simple rule-based automations triggered by row changes that send email via SendGrid, (4) user auth and per-user access control, (5) tests and error handling for connector failures and sync conflicts. Out of scope: enterprise governance, mobile offline sync, advanced ML/AI app generation, and enterprise connectors (Apigee/BigQuery). Include CI, deployment instructions (Docker + a managed Postgres), monitoring alerts, and unit/integration tests.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time — so the same evidence always produces the same number.
