Open source. Open possibilities.

Highlight.io is an open-source full-stack monitoring platform providing session replay, error monitoring, logging, and distributed tracing, with SDKs for multiple languages and self-hosted deployment options.

Iris is a local-first MCP server that scores AI agent runs for quality, safety, and cost using 20 built-in deterministic rules, an optional LLM judge, and a web dashboard — all on your machine with no account or telemetry.

Argos is a Go instrumentation library that adds OpenTelemetry traces, metrics and correlated logging to microservices via one Init/Run call, plus drop-in wrappers per client library. The root module has no vendor SDK dependencies; each integration ships as its own module.

Peaky Peek is a local-first, open-source audit and trust console for AI agents. It captures causal chains, verifies claims deterministically, and produces explainable trust scores with failure narratives — all running on your machine.

Jaeger is a CNCF-graduated distributed tracing platform for collecting, storing and visualising traces across microservices. It speaks OTLP, ships with a UI, collector and query service, and supports pluggable storage backends.

TundraLibs is a suite of independent, cross-runtime TypeScript libraries compatible with Deno, Bun, Node.js, Cloudflare Workers, and browsers. It provides modular tools for databases (ORM, drivers), authentication, validation, logging, tracing, caching, and HTTP routing.
