Building Internal Apps Without Code: Glide, Softr, AppSheet
Practice5 minInnovialabs editorial team
In short
Glide, Softr and AppSheet turn a Google Sheet or Airtable base into a working internal app in days; Glide is the fastest for mobile-style apps, Softr for portals on Airtable, AppSheet for Google Workspace teams and field work.
The short answer
If your team already lives in a spreadsheet — orders, equipment, requests, field visits — a no-code builder can put a proper interface on top of it: forms instead of raw cells, filtered lists per employee, buttons instead of copy-paste. Glide, Softr and AppSheet all do this well. The choice depends on where your data lives and who needs access.
- Glide — the quickest path from Google Sheets to a clean, mobile-friendly app.
- Softr — web portals and internal tools on top of Airtable or its own database, strong user groups.
- AppSheet — Google's builder, deep integration with Google Workspace, offline mode and data capture in the field.
From spreadsheet to app: the steps
The process is similar in all three tools.
- Clean the table first. One sheet per entity (Orders, Clients, Staff), one header row, no merged cells, one value per cell. Add a unique ID column.
- Link tables by ID, not by name. An order should store the client ID, not "Ahmed, the guy from the market".
- Add an email column to the staff table. Every builder uses it to log users in and decide what they see.
- Connect the data source in the builder. It reads the columns and suggests screens.
- Build three screens: a list (with search and filters), a detail view, a form to add or edit records.
- Set permissions: who sees all rows, who sees only their own, who can edit.
- Test with two or three real users before announcing it to everyone.
A typical first app: a request tracker where employees submit a form, a manager sees all requests on a board, and each person sees only their own.
How the three compare
| Glide | Softr | AppSheet | |
|---|---|---|---|
| Data sources | Google Sheets, Excel, Airtable, built-in Glide Tables, SQL on higher plans | Airtable, Google Sheets, built-in Softr Databases, plus other connectors | Google Sheets, Excel, Cloud SQL, BigQuery, AppSheet Databases and more |
| Interface | Mobile-first, looks native on phones | Web pages built from blocks, good for portals | Functional rather than pretty, works on phone and web |
| Permissions | Roles and row owners: users see only rows tied to their email | User groups and visibility rules per block and page | Security filters on rows, Google account sign-in |
| Logic | Actions, computed columns, workflows | Actions on buttons, workflows | Expressions, actions, automation bots |
| Strengths | Speed, design, ease | Client and partner portals | Offline use, barcode scanning, Workspace teams |
| Pricing model | Free tier, paid plans by apps, users and updates | Free tier, paid plans by users and features | Per-user licences; included in some Workspace editions |
Prices and limits change often, so compare plans on the official sites at the moment you decide. The main question is how the bill grows: per user, per app or per data update.
How to choose
- Data in Airtable and you need a portal for clients or partners — start with Softr.
- Data in Google Sheets, team on phones, you want it ready this week — Glide.
- Company on Google Workspace, employees work in the field, sometimes without internet — AppSheet.
- Unsure — build the same small screen in two tools in an afternoon. The one that feels natural to your team wins.
Limits you will hit
- Spreadsheets are not databases. With many thousands of rows and frequent edits, sync slows down and conflicts appear. Move to the builder's native tables or a real database.
- Per-user pricing is cheap for 5 people and expensive for 200. Count future users, not current ones.
- Complex logic — multi-step approvals, calculations across many tables, integrations with an accounting system — becomes a maze of hidden formulas.
- Lock-in. Screens and logic cannot be exported as code. Your data stays yours, the app does not.
- External users (clients, contractors) often require a higher plan.
- Security depends on settings. If row filters are wrong, a user can see other people's data. Check access with a test account for each role.
When an internal app becomes critical for the business and outgrows these limits, it is usually time to move to a custom CRM or web app, keeping the no-code version as a working prototype.
Common mistakes
- Building on a messy shared sheet that people still edit by hand.
- Hiding data with filters on the screen instead of real row-level permissions.
- One giant app for every department instead of small focused apps.
- No owner: nobody is responsible when a column is renamed and the app breaks.
