AppSheet?
BUILD FIRST
- One specific customer type and one primary use case
- A vertical slice that completes the main job without manual workarounds
- Visible limits, review steps, and a fallback when an external dependency fails
LEAVE FOR LATER
- Broad third-party integrations
- High-scale collaboration, syncing, and permissions
- Automation that can cause harm without human review
RESEARCH NOTES
What this tool actually does.
AppSheet is Google's no-code platform for building business apps from data sources like Google Sheets, SQL databases, BigQuery, and REST APIs. Apps are prototyped automatically by the AppSheet Editor, which scans connected data and generates views; users customize forms, views, actions, and automation using spreadsheet-like expressions rather than code. It offers mobile apps with offline sync, rich form fields (barcode, photo, signature, location), email/SMS/push notifications, Gemini AI assistance for app creation, Google Workspace integration (Chat apps, Docs smart chips, Apps Script), and document processing with OCR. Automations support triggers, conditions, branches, webhooks, and external events. Governance features include organizational policies, user/team management, security encryption, and audit logs. Deployment targets mobile, web, and Google Chat, with per-user subscription
RESEARCHED BUILD PROMPT
Give this to your coding agent.
Build a no-code app builder inspired by AppSheet's core workflow: connect a data source (CSV/Google Sheets-like import), auto-generate a CRUD web app with forms (text, number, date, photo, signature, barcode), and let users customize views, add filter/calculated expressions, and configure automated notifications. User-facing requirements: data-source import wizard; prototype auto-generation from detected columns; drag-and-drop view/theme editor; a formula bar with spreadsheet-like expression syntax for computed fields and view filters; an action builder for email/SMS-style notifications with templates; offline caching with a sync queue; and one-click deploy as a progressive web app. Technical requirements: React + TypeScript frontend; Node/Express or Supabase backend storing app definitions as JSON in SQLite/PostgreSQL; a safe expression evaluator implemented as an AST parser (never eval); JSON-schema app definition format; and a PWA service worker for offline support. Architecture should separate the expression sandbox (strictly scoped, no arbitrary code execution) from a code generator that maps app definitions to React components. Do not copy AppSheet branding, logo, or UI style; do not rebuild Gemini/AI generation, admin/governance consoles, Google Chat integration, or marketplace ecosystems. Out of scope: multi-tenant billing, production RBAC, native mobile binaries, conflict resolution, and ML features. Include a README covering setup, database schema, expression grammar, offline sync behavior, and limitations (e.g., no concurrent edit merging, limited function library, no push infrastructure).
