The honest answer
A custom table app for one workflow is very buildable; Airtable itself is not a small project. Flexible schemas, linked records, formulas, multiple views, permissions, automations, interfaces, realtime collaboration, and scale compound quickly.
The hard parts
What actually makes this difficult
- User-defined schema migrations
- Formula engine
- Realtime permissions across views
What you lose
The parts that make the paid product hard to replace
- General no-code platform
- Full formula language
- Enterprise collaboration suite
People still pay for Airtable because extreme flexibility; ecosystem and templates; reliable collaborative platform.
Prior art

Before you start
Airtable build questions
Can I vibe code Airtable?
Do not start by cloning Airtable. Build the specific business workflow that somebody currently runs inside Airtable.
Why is a vertical app easier?
You control the schema, validation, views, permissions, and terminology instead of building systems that let every user redefine them.
Can I add custom fields later?
Yes, but design a typed field model and migration strategy first. Arbitrary fields affect forms, filters, exports, permissions, and every view.
