The Glide alternative that generates the database, not just the app.
Glide layers a polished app over a spreadsheet or table you set up. Snill generates the whole thing (a relational data model, the app, and a REST API) from a plain-language description.
Glide is a lovely tool. Point it at a spreadsheet and you get a polished, mobile-friendly app faster than almost anything else can manage, and for a directory, a checklist, or a simple field app, that’s exactly the right amount of tool. It has also leaned hard into internal tools over the past year, which is the same ground we’re on.
The question is what happens as the data grows up. Glide builds an app on top of a data source you provide, and that source tends to stay spreadsheet-shaped. That’s ideal for simple lists and gets steadily harder as the real structure emerges: many connected collections, roll-ups across them, permissions, and rules that a flat table was never meant to carry. At that point you’re designing around the data model instead of being carried by it.
A real database, generated
Snill starts from the data rather than the sheet. You describe your business the way you’d brief a colleague, something like “clients, projects, and invoices; a project belongs to a client; only managers can see rates”, and Snill generates a relational data model: typed fields, lookups, aggregations, field-level access control, server-side logic, and an auto-generated OpenAPI REST API over the whole thing. The app and dashboards come with it.
Keep Glide for the slick app over a simple dataset, because it’s wonderful at that. When the data becomes a system, describe it to Snill and get a system built on a relational backend, with the API and permissions included, and every change to the model versioned and reversible.
What Glide gets right
Beautiful apps, fast
Point Glide at your data and get a polished, mobile-friendly app in no time. For a directory, a checklist, or a light tracker, little else feels as quick or as clean.
Genuinely approachable
It's true no-code, with Glide Tables as a built-in data store, and GlideOS bringing an AI-led way to build. Non-technical teams get productive quickly.
Aimed squarely at internal tools
Field apps, internal directories, simple workflows. Glide has leaned into turning data you already have into a working team tool, and it's very good at that job.
Where the model starts to strain
It layers on your data
Glide builds an app over a data source, either a spreadsheet or a Glide Table, and its AI can scaffold one for you. The app is a front end, and you still own the shape of the data underneath.
The data model stays table-shaped
Perfect for simple lists, and harder as the data becomes genuinely relational. Glide has relation and rollup columns, but they're value-matched computed columns rather than a relational model, so many connected collections and cross-collection rules are a stretch.
It's a front end more than a backend
Glide has an API and workflows, but there's no generated relational model, no role-gated rules that reject invalid changes at the data layer, and no auto-generated OpenAPI REST API over a real database. The operational backbone is lighter than an operational system needs.
Glide vs Snill
| Glide | Snill | |
|---|---|---|
| Where the data lives | A spreadsheet or Glide Table you set up, with the app layered on top. | A relational data model Snill generates from your description. |
| Data model | Table-shaped, best for simple lists and light relations. | A relational model with lookups, roll-ups, and typed fields. |
| How you build it | Point Glide at a data source, or start from GlideOS, and it generates the app UI. | Describe the app, and Snill generates the data model, app, and API. |
| Logic | Computed columns, AI columns, and workflows you configure. | Calculations, workflows, and triggers you describe, enforced on the server rather than in the UI. |
| The API | An API to read and write your Glide tables. | An auto-generated OpenAPI 3.0 REST API over the relational model, plus webhooks. |
| The AI after launch | Glide AI and GlideOS help build the app and enrich columns. | Still there once the app is live. It knows your data model, so anyone can ask it a question or ask for a change, and it proposes rather than applies. |
| Best if | You want a slick app over a simple dataset. | You need a relational system with an API and server-side logic. |
Who should switch, and who shouldn't
Stay with Glide if…
You need a slick, mobile-friendly app over a simple, mostly flat dataset, like a directory, a checklist or a light tracker. Glide makes those genuinely delightful, and faster than almost anything. Keep it for that.
Try Snill if…
Your data has grown real structure, with many related collections, permissions and server-side rules, and an app layered on a spreadsheet is fighting the shape of it. You want the relational backend and the API generated rather than bolted onto a sheet.
Frequently asked.
Is Snill a Glide alternative?
For operational apps with real data, yes. Glide layers a polished app over a data source you provide, and Snill generates the relational data model, the app, and a REST API from a description. If your Glide app is straining against a spreadsheet-shaped model, Snill gives you a real one.
Doesn't Glide have AI and its own tables?
Yes, and both are good. Glide Tables give you a built-in data store, and GlideOS adds an AI-led way to build. The difference isn't the AI or having tables. It's that Snill generates a relational data model with lookups and an auto-generated REST API, rather than an app over a mostly flat table. The assistant also stays in the finished app, where it knows that model, so someone in the field can ask a question of the data instead of you building another screen for it.
Can I move my Glide or spreadsheet data to Snill?
Yes. Export to CSV and import it into Snill with field mapping. You describe the relational structure you want and Snill builds it around your data.
Do I need a spreadsheet to start?
No. Glide typically starts from a data source, though its AI can scaffold one, while Snill always starts from a plain-language description and generates a full relational model with lookups, roll-ups, permissions and the API included. Import existing data if you already have it.
What does Snill cost?
Snill is free to start for solo operators, with a Pro plan for teams. You're paying for your Snill account, your data is yours to export anytime as CSV or JSON, and your app's full model as JSON.
