Watchdog reads C#, Java, TypeScript, Python, Go and more, and grades your whole product as one.

Watchdog reads C# with the C# compiler's own tools, so it understands the code the way the compiler does. Every design grade and every code-level check is read in full.

Watchdog reads F# with the F# compiler's own tools. F# code often describes what happens in a business as a set of event types, and builds its current state by replaying those events. Watchdog reads that style directly, so Domain Modelling and Event Sourcing are read in full.

Watchdog reads Java with a tool that works out the types in the code the way the Java compiler does, so the design is read in full. Several code-level trap checks read Java too, such as the check for errors that are caught and ignored.

Watchdog reads Kotlin with the Kotlin compiler's own tools, so the design is read in full, including the ways Kotlin code usually describes events and values. Several code-level trap checks read Kotlin too, such as the check for errors that are caught and ignored.

Watchdog reads VB.NET with the same compiler tools it uses for C#, so the design is read in full.

Dart code describes its data in detail, so Watchdog can tell business data apart from screens and database rows. Several code-level trap checks read Dart too, such as the check for errors that are caught and ignored.

Elixir code usually builds its current state by replaying events, and Watchdog reads that style directly for Domain Modelling and Event Sourcing.

Modern PHP code states the type of each value, so Watchdog can follow which part of the code calls which and read the design from it. Several code-level trap checks read PHP too, such as the check for errors that are caught and ignored.

Rust code states the type of each value and which parts of the code may change it, so Watchdog can tell business data apart from database rows, whichever of the common database libraries the code uses.

Scala code describes its events, values and IDs in detail, so Watchdog can tell business data apart from database rows and messages, and reads Domain Modelling and Event Sourcing from it. Several code-level trap checks read Scala too, such as the check for errors that are caught and ignored.

Swift code states whether a value is copied or shared, and what each type promises to do, so Watchdog can tell business data apart from stored records, including data kept with Core Data, Realm or SwiftData. The check for errors that are caught and ignored reads Swift too.

Watchdog reads TypeScript with the TypeScript compiler's own tools. It can tell an event apart from an error result even when both are written the same way in the same file, and it tells business data apart from database rows, whichever of the common database libraries the code uses.

Watchdog reads Erlang with Erlang's own parser. It finds problems typical of Erlang systems, such as a message handler that blocks while it waits, a change that is saved and sent as a message without making sure both happen, and a query that also changes data. The check for errors that are caught and ignored reads Erlang too.

Watchdog reads Go with Go's own type checker, the same one Go uses when it builds your code. It reads how the packages depend on each other, how events are handled and replayed, and how business records refer to each other. Several code-level trap checks read Go too, such as the check for errors that are caught and ignored.

Watchdog recognises Python's business data by how the code marks it, such as values, database records and events, whether or not the code states its types. Several code-level trap checks read Python too, such as the check for errors that are caught and ignored.

Watchdog recognises Ruby's business data and events by how the code marks them, and reads the event-replaying style Ruby code writes with blocks. Several code-level trap checks read Ruby too, such as the check for errors that are caught and ignored.

Watchdog reads JavaScript with the TypeScript compiler's own tools. It reads how the modules depend on each other, how complex the code is, how its classes are shaped and which code changes which data.
