Stackby

What Stackby is

Stackby is a no-code database and work platform that describes itself as spreadsheets, databases, AI agents and automations in one place. Its home page line is "It's as easy as a spreadsheet, but you can mould it into a powerful relational database." The people it speaks to are marketing, HR, sales and operations teams who want to organize, build and automate their own work without a developer. The pricing FAQ adds that it serves companies of all sizes across every industry, "even with strict data governance rules".

The company says it is trusted by 100,000+ diverse companies worldwide and shows a G2 rating of 4.8. Its About page gives the mission: the world still runs mostly on spreadsheets, and non-technical people should have modern building blocks to create their own no-code tools while keeping the ease of traditional ones. The FAQ says the company focuses on "transparency, openness, performance, scalability and data security."

What you build and how

You build in a workspace made of stacks, which are Stackby's databases. Each stack holds tables with rows, and the site advertises 30+ unique column types, so a table can model far more than text and numbers. Import is the usual starting point: free tools turn CSV, Excel, XML and JSON files into a database, and importers bring in data from tools such as Google Sheets, Trello and Asana. You can also ask AI to create a database for you. The home page has sections titled "Build your database or app with AI" and "AI Powered Databases", and the product menu names AI Fields and Stackby AI. The trial line adds "Bring your own AI," and the integrations list includes OpenAI, Anthropic and Gemini.

Around the tables sit the building blocks the product menu names: Views, a Form Builder, Automations, Reporting, a Page Designer, API Connectors, Powerups and the Stackby API. Views are different ways to look at the same records, and paid plans add personal and locked views. The Form Builder collects submissions, and the pricing page says form submissions never cost a seat; paid plans add custom branded forms. Automations are metered by internal automation runs per plan, with a run history kept from 6 months to 3 years depending on the tier.

The app builder side is the Interface (App) Designer. Even the free plan includes it, with 1 app per stack, so each database can carry its own app interface. Paid plans raise that to 3, 10, 20 or 25 apps per stack, add publishing, and from Business up include a custom domain. Portals for outside guests are an add-on priced per 10 guests. Together these put Stackby among app builders: the database is the back end, and the designed interface or portal is what a teammate or a client uses. An Apps Marketplace holds ready-made apps.

API Connectors are a distinctive piece. A column can be linked to an outside API so that cells fill from another service, and the plan table counts these column-linked connectors (2 on Free, up to 20 on Pro) and the automatic API runs per month (500 on Economy up to 10000 on Enterprise). On Free the cells refresh manually, on paid plans automatically. Synced tables per stack and 25+ Powerups arrive from Business up.

Integrations are listed by name: Zapier, Make, Slack, Microsoft Teams, Meta Ads, YouTube, OpenAI, Anthropic, Gemini, Pabbly Connect and Integrately. Solution pages target marketing, HR, project management, operations, sales CRM, finance and product development, each framed as a team that organizes and automates its own process. If you want to take the data elsewhere, the company says you can export it anytime to Excel, CSV or other formats.

Stackby also ships desktop and mobile apps. The Apps page lists a Mac app for macOS 10 or higher, a Windows app for Windows 7 and later in 64-bit, an iOS app for iOS 12.0 and later on iPhone or iPad, and an Android app for Android 5.0 and above.

The FAQ adds that the paid plans start "at $10/user/month" on monthly billing and that yearly plans are "atleast 5x cheaper" than monthly ones, with yearly seats bought in increments of 3, 6, 10, 15, 20 or 25. Stackby charges only for users with editor or creator access to at least one stack. Read-only collaborators, form submissions and share links carry no charge, and an editor added partway through a month is charged only for the remaining days. You can start a 14-day trial of Business or Pro, and upgrade, downgrade or cancel at any time. The site mentions special plans for nonprofit and education organizations, and the FAQ points to a security practices page and offers a security whitepaper by email.

Who it suits and who it does not

Stackby suits a small marketing, HR or ops team that wants a relational database with forms, automations and an app layer at a low per-seat price. A founder can start free with up to 5 editors, bring in clients as read-only guests, and pay only when more people need edit access. Teams that live on outside data, such as Meta Ads or YouTube figures, can pull it into API-linked columns that refresh on their own on paid plans.

The AI angle helps a team with no data modeler. You import what you have or describe what you want, let the AI propose a database, then adjust the column types by hand, and you can bring your own model from OpenAI, Anthropic or Gemini.

The caveats are mostly limits. 1500 rows per stack and a 2MB upload limit on the free plan are tight for large datasets or document-heavy work, and the free plan's 100 automation runs suit a first project more than a busy department. Custom domains and portals cost extra below Business, and single sign-on waits for Enterprise. Monthly billing costs considerably more than annual, so a team should settle its seat count before committing to a year.
