Which one fits
Choose Retool when
- You need connectors to systems outside Google.
- Your builders want components and source control.
- The app must live outside Workspace and Apps Script.
Choose Applane when
- The tool only needs Sheets, Drive, BigQuery or Firestore.
- Your team wants to build tools by describing everyday work.
- You want your apps and data in your Google environment.
Use Applane when the tool should live as an Apps Script project in your Google Workspace; use Retool when you need its broader internal-app builder.
