Five is a cloud development environment for building custom business web applications. It is aimed at internal tools, customer and vendor portals, approval workflows and replacements for spreadsheet-based processes. The company describes its approach as going from prompt to deployed business software.
A central part of the product is V, Five's AI assistant. Users describe the application they need in plain language, and V helps create, modify and extend it. Around that sits a conventional toolset: a visual database builder, SQL query tools, a code editor for JavaScript and TypeScript, and an auto-generated responsive interface.
Five also frames itself as a structured alternative to prompting a general AI code generator for a full application. Instead of a large repository of raw files, it organizes AI-generated logic into modular components with traceable dependencies and audit logs.
A project starts with a description of the tool you need. According to Five, V models the database schema, creates tables, fields, relationships and pages, and configures role-based access, giving a working app structure that developers then refine with visual tools and their own data.
Data can live in Five's built-in MySQL database or in external sources. Five connects to external MySQL, Microsoft SQL Server and SQLite databases, as well as REST API and OData endpoints. Developers write SELECT, JOIN and UNION statements or use a visual query builder, and results feed forms, charts, dashboards and reports.
When the app is ready, it is deployed as a containerized application on Kubernetes-orchestrated cloud infrastructure. Developers promote it to development, test or production with one click and do not need to learn Docker, Kubernetes or cloud configuration.
On the data side, Five offers a visual MySQL builder with primary and foreign keys, CSV import and a SQL query builder. Business logic is written in JavaScript or TypeScript, with support for processes, scheduled jobs and event-triggered actions such as in-app notifications, emails and PDF reports. AI can also interpret and debug code inside the editor, so no external IDE is needed.
The interface layer is generated automatically and is responsive across phones, tablets and desktops. Developers can customize its look by point-and-click or CSS, and can add UI plugins written in JavaScript.
For governance, Five lists audit trails that log AI modifications and record changes, dependency mapping, role-based access control, SSO and MFA. It states that data is encrypted at rest with 256-bit AES through Azure Storage and in transit with TLS 1.3.
Five is an AI-powered development environment for building and deploying custom business software. Users describe an app to its AI assistant, V, which helps create, modify and extend it, and Five hosts the result. It is typically used for internal tools, portals and custom business apps.
Basic costs $29.99 per month, or $27.49 per month when paid annually. Team is $99.99 per month and Business is $279.99 per month. Enterprise pricing is custom and available by contacting Five.
Yes. The free trial gives full access to the development environment and requires no credit card. It does not include AI credits, so using the V assistant requires a paid plan or purchased tokens.
Every app can use Five's built-in MySQL database. Five can also connect to external MySQL, Microsoft SQL Server and SQLite databases, and to REST API and OData endpoints.
Some knowledge helps. Five recommends a basic understanding of relational databases, SQL and JavaScript. Simple apps can be built almost without code, and V can help generate code and SQL.
According to Five, the user owns the application and its data, including the app design and data uploaded by end-users. Five owns the intellectual property of its development environment. Production databases are isolated from other developers' data.
Five deploys containerized applications on cloud infrastructure orchestrated by Kubernetes. Apps are deployed with one click to development, testing or production, and users do not need Docker or Kubernetes skills.
Five suits solo developers, development teams and startups building custom business apps such as portals, inventory systems and spreadsheet replacements. Enterprises can request custom infrastructure and support.
