Formlets vs uCalc

Formlets is a web-based builder for contact forms, order forms, surveys and other forms used to collect information. Forms can send data to a mailbox, XLS or integrated platforms, and can be shared through a hosted link or embedded using iframe or modal code. The drag-and-drop designer includes conditional display, calculations, custom themes, e-signatures and templates. Forms support email notifications, validation and file uploads, including uploads up to 2 GB. Formlets advertises more than 2,000 software integrations and lists PayPal and Stripe payment options. Its free Personal plan permits one published form with unlimited responses; creating a free form requires neither signup nor a credit card. Paid plans start at $15.00 per month billed annually, with plan prices listed excluding VAT for several offerings. Higher plans include features such as custom-domain URLs, team accounts, and priority or full-service support. Formlets is identified with Oxopia and headquartered in Horebeke, Belgium.

uCalc is a C++, C# and VB SDK for evaluating expressions and transforming structured text. Its Fast Math Parser evaluates expressions defined at runtime, including those using custom variables, functions and operators. It supports parsing an expression once and evaluating it repeatedly. The Transformer tokenizes text before matching, for tasks such as code refactoring, linting and data transpilation. The String SDK adds mutable, token-aware search and replace, live substring views and chainable text operations.

The SDK is listed for Windows, macOS and Linux and is offered through NuGet; a Visual Studio extension brings token-aware search and transformation into the IDE. The free Community SDK plan costs nothing for eligible users with less than $100,000 in annual gross revenue. Commercial SDK plans cost $695 a year or $1,295, paid once. Preview safeguards for untrusted input are incomplete, and two legacy apps have not been updated in over 10 years.
