Küstenlogik is a software publisher focused on developer tooling for the .NET ecosystem, with its catalog centered on Bowire, an interactive multi-protocol API browser and command-line interface. Bowire addresses a common challenge in modern software development: today's applications rarely communicate through a single protocol, and developers often juggle separate tools for testing, exploring, and debugging different service types. By unifying support for gRPC, REST, GraphQL, SignalR, MCP, server-sent events, WebSocket, MQTT, Socket.IO, and OData within a single environment, Bowire allows engineers to inspect endpoints, craft and send requests, and observe real-time message streams without switching between disconnected utilities. Typical use cases include API exploration during integration work, manual testing of backend services, debugging event-driven or streaming architectures such as SignalR hubs or MQTT-based IoT pipelines, and validating GraphQL schemas or OData queries against live servers. The combination of an interactive browser with a CLI makes the product suitable both for hands-on, exploratory sessions and for scripted or automated workflows embedded in build and test processes. Bowire fits naturally into categories such as API development tools, protocol clients, debugging and diagnostics utilities, and developer productivity software. It is aimed at backend engineers, integration specialists, QA professionals, and platform teams working with heterogeneous microservice environments where REST alone no longer covers the full communication surface. As a publisher, Küstenlogik positions itself in the niche of polyglot-protocol tooling, offering .NET-oriented professionals a consolidated way to understand and interact with the diverse services their applications depend on.
