LightSpeed reduces the code you need to write

LightSpeed was designed to make writing software easier, faster and more enjoyable. There is minimal impact on your domain model classes and no need to write bulky XML mapping files. LightSpeed is all about being fast.

LightSpeed minimizes database round-trips

Round-trips to the database and unoptimized queries are performance killers in any software development. We developed innovative new methods of fetching data to help ensure efficient data retrieval for your projects. We understand that performance matters for your customers.

LightSpeed is very easy to learn

The API for LightSpeed was designed to be simple, intuitive and easy to understand. Included in every edition is a comprehensive set of samples that show how to setup LightSpeed, run various queries, and much more. Tutorials can be found in the help documentation and blog posts highlighting key areas of functionality are provided often.

LightSpeed is commercially and fanatically supported

We strongly believe that a supported customer is a happy customer. Software development can be challenging and knowing that there is somebody to turn to that will always answer your question means you can sleep easy. Normal support can be found in our forums and Enterprise customers can use the priority email support facility.

LightSpeed uses modern design patterns

Design patterns help developers create maintainable solutions and we are strong believers in aiding the use of these patterns. LightSpeed incorporates several design patterns right out of the box (Repository Pattern for example) and the samples show how to use LightSpeed with other design patterns.

LightSpeed is cost effective

We picked a licensing model that makes it easy for you to calculate the cost for a project. No per-seat pricing, no need to install a licensing server - you simply buy a license for the IP owner (e.g. Just 1 if you build one project, 5 if you build 5 systems for 5 different customers).

The time you will save by being able to deliver solutions faster and more efficiently means your LightSpeed purchase will pay for itself many times over in your development projects.

LightSpeed supports many different database engines

The decision on what database engine you use is completely up to you and LightSpeed supports that. Currently LightSpeed works perfectly with SQL Server, Oracle, PostgreSQL, MySQL and SQLite. Changing to a different database is as simple as changing a single configuration value.

LightSpeed supports everything it should

Nullables? No problem! Generics? Baked in! LightSpeed was designed 100% from the ground up to support .NET 2.0 language features. Everything in LightSpeed behaves exactly as it should.

LightSpeed source code is available

If you need the additional assurance, the Enterprise edition of LightSpeed ships with the complete source code to LightSpeed including many of the unit tests.

LightSpeed supports Visual Basic and C#

If your favorite programming language is C# or VB then you'll be pleased to know that we focus on testing our software in both environments and provide documentation to ensure that both languages are supported. Your programming language is your choice.

We always deliver more than expected

Once you have purchased LightSpeed we don't just forget you - we work hard to continue adding value to your purchase by providing nightly releases, updated documentation and more. If there is anything we can help you with you are always welcome to ask.
