Cross-platform multi-protocol mock server — HTTP, WebSocket, gRPC, GraphQL, TCP, Redis, SMTP, MQTT — with a web UI, scenario system, and fault injection.
High-throughput, load-bearing Go HTTP engine — a protocol-aware dual-architecture (io_uring & epoll) that leads driver-backed and write-heavy throughput, with a familiar Gin/Echo-style API and zero-allocation hot paths.
Durable jobs and checkpointed workflows on the SQL database you already have — Postgres, MySQL, or SQLite. Embedded dashboard, signals, timers, transactional enqueue.
