Twingrid — real-time 2-way Airtable ↔ Google Sheets sync, no helper columns (validating before I build)

Hi everyone — I’m validating an idea before writing any sync code, and this community seems like exactly the right place to get honest feedback.

The problem I keep running into:

Most tools that claim to sync Airtable with Google Sheets are actually one-way importers (Coefficient, Coupler, Dokin). Edit the sheet and nothing flows back to Airtable.

Unito does real 2-way sync but forces “UnitoID” and “Last Modified” columns into your sheet — delete them and the sync breaks — and costs $65–$299/mo.

DIY via Apps Script works until you rename a field or change a type.

What I’m building:

Twingrid — a Google Sheets add-on for real-time, 2-way Airtable ↔ Sheets sync that:

  • Works both directions — edit in Airtable or Sheets, both update
  • Adds no helper columns to your sheet
  • Handles field types properly (linked records, multi-select, attachments, dates)
  • Self-heals via a background reconciliation pass so it never silently drifts
  • Starts at $15/mo

Where I’m at:

Pre-build. Waitlist is live at twingrid.io — I’m collecting signups and a short 3-question survey (which plan fits, what tool you use today, what breaks most often) before committing to build.

Would love your input:

  • Do you currently sync Airtable data into Google Sheets? What do you use?
  • Is 2-way a real need, or does one-way cover your workflow?
  • What breaks most with whatever you’re using now?

Genuinely trying to figure out if this solves a real problem before spending months on it. Any feedback appreciated.
