Open source. Open possibilities.

qyl is a local OpenTelemetry investigation stack for .NET. It allows developers to instrument applications with minimal code, run a collector locally, and visualize traces, logs, and metrics via an embedded dashboard or API.

Effect is a comprehensive TypeScript library designed for building robust, type-safe, production-grade applications with built-in support for typed errors and dependency injection.

Prefect is a Python-based workflow orchestration framework designed to build, automate, and monitor resilient data pipelines with features like scheduling and retries.

Agentic OS is a self-hosted control plane for running business operations as a fleet of AI agents. It features a cost-aware LLM router, cross-module workflows, and human-in-the-loop approvals for finance, support, and compliance.

openstatus is an open-source uptime monitoring and status page platform built around infrastructure as code. Monitors, status pages and notification channels are declared in YAML or Terraform, applied via CLI or CI, and managed through an API, MCP server or AI assistants. It offers 28 global check regions, incident communication and self-hosting options.

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.

SolarisPKN-Stats is an automated system for collecting, storing, and updating project statistics from multiple platforms into structured JSON files.

rzeka is a single-threaded reactive event bus for C# built on Rx.NET that features automatic causality tracking and a real-time browser-based debugger.

Cilium is an eBPF-based networking, security, and observability solution for Kubernetes. It offers CNI networking, identity-based L3-L7 policies, distributed load balancing that can replace kube-proxy, multi-cluster Cluster Mesh, service mesh with mutual authentication, and Hubble observability. It is a CNCF Graduated project with Apache 2.0-licensed user space code.

Swarm is a local-first control plane for AI-agent development that monitors every Claude Code, Codex, Gemini, Grok, Aider, and opencode session on your machine — tracking live tool calls, token spend, cost, tasks, worktrees, and resources — with rules enforcement, a coordination ledger, and a unified dashboard.

Apache SkyWalking is an open-source APM system designed for microservices, cloud-native, and container-based architectures. It provides distributed tracing, multi-language agents, eBPF monitoring, native BanyanDB storage, log pipelines, alerting, and AI-powered anomaly detection.

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.

Vector is an open-source observability data pipeline written in Rust. It collects, transforms and routes logs and metrics as either an agent or an aggregator, letting teams control where telemetry goes and reduce vendor costs.

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.

A DeepSeek Harness plugin that exports OpenTelemetry traces, metrics, and logs to GreptimeDB, with seven Grafana dashboards for tracking token usage, costs, and performance of AI agent runs.

LogSquirl is a fast, open-source log explorer for Windows, macOS, and Linux. Search multi-gigabyte files, follow live logs, and chart patterns. Built with Qt6/C++, it's a fork of klogg and glogg.

SovereignKit is open-source Solana infrastructure for measuring transaction accessibility failures, separating RPC acknowledgment from ledger evidence, detecting route asymmetry, and enabling bounded fail-open routing. v0.1 is a controlled proof plus Devnet validation, not a provider ranking.

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.

AgentLeak is an open-source privacy testing tool for AI agents. It detects data leaks across tool calls, memory, and logs using a local Python SDK, CLI, and MCP tools, providing redacted reports and CI gates without cloud dependencies.

slogcp is a Google Cloud-native structured logging handler for Go using the standard slog API. It enables Cloud Logging, Trace, and Error Reporting integration for services on Cloud Run, GKE, and more.
