Which one is for you
Pick Adalo if
- Fits if you can't code and want one project to ship to iPhone, Android and the web
- Works for apps built around a database, like bookings or a directory
Look elsewhere if
- Pricey if you just want one small app live, since publishing starts at Builder, $624 a year or $65 a month
- Tight if you're staying free, with 500 records per app, 5 Ada prompts a month and nothing published
- Watch out: Builder includes only 1 instant update a month, and localization, crash monitoring and analytics are add-ons on it
- Not for you if you need external databases or the Collections API, which start on Business at $200 a month
- Watch out: the app stores add their own fees, $99 a year for Apple and $25 once for Google Play
Pick Stacker if
- Fits if you want a client portal on top of a spreadsheet or database
- Works for small teams of up to 5 inside users and one app
Look elsewhere if
- Tight if you grow: Starter is 1 app, 5 internal users, 50 external users
- Pricey if you want unlimited outside users and custom scripts, which need Plus at $149 a month
- Watch out: SQL and Salesforce connectors and SSO are Enterprise only
- Watch out: the AI agents are sold as a separate product
- Skip it if you want a free plan, as only a 30-day trial exists
How we grade them
| 2.2GPAAdaloFair | 2.2GPAStackerFair | |
|---|---|---|
| Value for money | DBuilder, the cheapest paid plan, is $624 a year, $52 a month, or $65 billed monthly, when builders here sit at $19 in the middle and the dearest tenth starts at $30. That buys 2 published apps and 5 editors, with push, Stripe and custom actions. No usage charges on top. | CStarter is $29 a month, just over the category's $25 dearer-quarter line, but it is capped at 1 app and 5 internal users. Plus is $149. |
| Free plan and trial | CFree with no time limit: unlimited test apps, one free app build, 500 records an app, 1 editor and 5 Ada prompts a month. But publishing needs a paid plan. You can build the whole thing and never ship it, and custom domains and the app stores need paying for. | CA 30-day free trial with every feature unlocked and no card needed. After that, nothing is free. |
| Features | BIt covers the whole job. Every screen sits on one drag-and-drop canvas with 200+ components, Ada builds and edits from a prompt, and a single version publishes as a web app and as native iOS and Android builds, each with a hosted Postgres database and Stripe payments. Bubble and thunkable do the same, so no A. | CPortals, internal tools, two-way data sync, permission rules and a custom domain. SQL and Salesforce connectors are Enterprise only, and AI agents are a separate product. |
| Ease of use | CNo rating on record, and this is a visual builder with a curve to it. Ada will scaffold from a prompt, but mostly you're dragging components onto a canvas, laying out every screen and shaping the collections behind them. You can preview on your own phone. | CNo store rating on record, and you build the app yourself and connect your data. |
| Platforms and integrations | BYou build in the browser only, with no desktop or phone app for building. What comes out runs on iPhone, Android and the web. It connects to Stripe and Zapier; custom actions for outside APIs start on Builder, and external databases such as Xano and the Collections API need Business. | BWeb, with four data-source integrations listed. No phone or desktop app. |
| Best for | one no-code project for iPhone, Android and web | client portals and internal tools on top of your data |

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
