Caspio vs Uno Platform

What Caspio is

Caspio is a proprietary hosted low-code platform for building database-backed web applications from tables, forms, reports, charts, authentication and automation components called DataPages and DataParts. Current Team pricing is $300 monthly or $270 per month billed annually; Business is $600 or $540 annual-equivalent, while Enterprise is quote based. Every plan advertises unlimited app users, but platform resources are not unlimited: DataPages, records, logs, file storage, emails, directories, integration calls and document generation have plan allowances, add-on blocks, overage prices and hard upgrade ceilings.

What Uno Platform is

Uno Platform is an Apache-2.0-licensed .NET UI framework for building applications from a shared C# and XAML or C# Markup codebase across Windows, Android, iOS, WebAssembly, macOS and Linux. Its open-source runtime is complemented by account-based Studio tooling such as Hot Reload and Hot Design. Actual target coverage depends on the development host, IDE, .NET workloads, platform SDKs and renderer, so single-codebase does not mean identical tooling or behavior everywhere.

What Caspio is built to do

Visual application builder

Creates forms, searchable reports, charts and database workflows through DataPages and DataParts.

Hosted relational data

Stores application records and files with plan-specific capacity and logging allowances.

Identity management

Provides directories, two-factor authentication and optional external SAML app connections.

Integration surfaces

Connects external services through REST APIs, webhooks, scheduled import/export and extension agents.

What Uno Platform is built to do

Shared .NET UI

Uses C# with XAML or C# Markup to share application and interface code across targets.

WebAssembly target

Runs supported .NET UI applications in modern desktop and mobile browsers.

Skia desktop

Targets desktop environments on Windows, macOS and supported Linux configurations.

Studio tooling

Adds account-based Hot Reload and Hot Design workflows where the compatibility matrix permits.

Choose Caspio if

• Forms, portals, directories and workflow apps built around structured records
• Projects needing many end users but predictable builder and resource capacity
• Teams that can pilot DataPage, record, API, storage and compliance needs before selecting a plan

Skip Caspio if

• The application requires full source-code ownership or unrestricted infrastructure control
• The budget cannot absorb record, API, storage or compliance add-ons
• Complex real-time UX, offline-native mobile behavior or unusual database semantics dominate the product

Choose Uno Platform if

• C# teams extending WinUI-style skills beyond Windows
• Products whose required hosts and targets appear in the supported environment matrix
• Applications that can test and tune each platform rather than assume pixel-identical behavior

Skip Uno Platform if

• A required target or debugging workflow is unsupported from the team's development hosts
• The product depends heavily on native controls or APIs not proven through Uno abstractions
• You cannot maintain platform SDKs, .NET workloads and target-specific QA

Caspio: pros & cons

• Rapid database apps: Visual tables, forms, reports and workflow components shorten conventional CRUD delivery.
• Unlimited application users: Core plans do not use a simple per-end-user subscription model.
• Hosted operations: Caspio provides the application platform, database hosting and deployed web interfaces.
• Published capacity table: Base allowances, prepaid add-ons, overages and plan ceilings are visible before purchase.
• Unlimited users does not mean unlimited resources: Records, DataPages, storage, calls, emails and logs remain metered or capped.
• Meaningful entry price is substantial: Team starts at $300 month-to-month before optional capacity or compliance charges.
• Portability needs planning: Data can be exported, but a complete Caspio application is tied to proprietary DataPages and platform behavior.
• Security and compliance are tiered: Premium identity, audit, HIPAA/BAA, dedicated resources and governance can require higher or special plans.

Uno Platform: pros & cons

• Broad target matrix: One .NET solution can target Windows, Android, iOS, browsers, macOS and Linux.
• Familiar Microsoft UI model: C#, XAML and WinUI-aligned APIs reduce conceptual switching for .NET UI teams.
• Open-source core: The Uno repository is available under Apache License 2.0.
• Multiple IDE choices: Official setup paths cover Visual Studio, VS Code and JetBrains Rider.
• Host-dependent targets: iOS requires a current Mac/Xcode path, while WinAppSDK development is unavailable from macOS and Linux hosts.
• Compatibility matrix: IDE, host OS, target, .NET version and renderer combinations do not all offer the same build or debugging support.
• Upgrade work: Migration notes include removed target frameworks, tooling updates and platform-specific API changes.
• Studio boundaries: Hot Design requires sign-in, supported project versions and XAML; it excludes C# Markup and currently has target limitations.
