Documents and notes decision
Airtable
Do not rebuild — a single developer can recreate a small portion, but Airtable's enterprise-grade scale, security certifications, and ecosystem are durable advantages that make a full replacement impractical for most teams.

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
- A minimal replacement stores structured records, presents editable grid and form views, wires simple automations, and exposes a REST API for integrations.
What it still won’t have
- Enterprise-grade scale and multi-100M record infrastructure
- Certified compliance posture (ISO 27001, HIPAA, SOC 2)
- Large integrations and marketplace ecosystem
- Polished UI, templates, and onboarding flows
- Advanced data residency / EKM features and audit tooling
What remains hard
- Infrastructure at scale
HyperDB with record limits in the hundreds of millions
- Infrastructure at scale
Scale Build apps on top of massive data sets with 100M records
- Compliance and regulation
ISO 27001, HIPAA, SOC 2 Type II, and GDPR compliant

The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal Airtable-like app using Postgres, Next.js (React), and Supabase for auth and hosting. In scope: a Postgres schema supporting multiple workspaces and relational tables, a REST+GraphQL API to CRUD records and attachments, a React grid view, record detail and form views, workspace/user/role permissions (owner/editor/viewer), a basic automations engine (watch DB events and run webhook/email actions), and connectors for one external integration (Slack or Gmail). Out of scope: multi-100M record scale optimizations, enterprise compliance certifications, marketplace, and mobile apps. Include input validation, authentication error handling, retry logic for webhooks, and unit/integration tests for API and automations.

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.
