What We Ship

Micro Service Mesh

A sub-megabyte service mesh proxy that handles mTLS, load balancing, and circuit breaking with single-digit-microsecond overhead. Ships as a single binary, configurable via TOML, and runs happily on a two-core VM. No JVM, no Envoy sidecar bloat, no ceremony.

🔀

Route Engine

A lightweight API gateway that routes HTTP and gRPC traffic to microservices with guaranteed ordering and rate limiting. Supports path-based routing, header injection, and request transformation out of the box and adds under 50 microseconds of overhead per hop.

💾

Log Collector

A zero-copy structured logging agent that captures, transforms, and ships logs at wire speed. Supports stdout, file tailing, and journald sources with output to S3, Elasticsearch, and Loki. Storage footprint is 80 percent smaller than competing collectors thanks to a custom compression format.

🖥️

CLI Dashboard

A terminal-native monitoring interface that displays service health, request rates, error budgets, and deploy status in a single pane. Runs over SSH, works on any terminal emulator, and uses less than 15 MB of memory. Perfect for headless servers and lean ops teams.

🔧

Deploy Compiler

A deployment configuration language and compiler that turns human-readable TOML definitions into optimized Kubernetes manifests. Validates resource limits, health checks, and security contexts at compile time so errors surface before deploy, not in production.

🛡️

Drop-In Rate Limiter

A standalone rate-limiting proxy that sits between any service and its clients. Enforces request quotas, concurrency limits, and backpressure with sub-microsecond overhead. Deploy it in front of third-party services without modifying a single line of their code.
