o11y.one - The only observability tool you'll ever need

O11y One — The Next-Generation Unified Observability Platform for the AI + Product Era

O11y One is a modern, end-to-end observability platform built to help companies of all sizes streamline their product lifecycle, optimize AI/LLM performance, and run production environments with confidence — all while paying a fraction of what legacy vendors (<Insert any "Logs" vendor here>) charge.

It unifies all OpenTelemetry, Product and AI-specific signals into a single, high-performance data plane:

LLM & AI observability to ensure deterministic agent outputs, surface hidden costs, and detect performance bottlenecks before they impact users
Traces for distributed system & model execution analysis
Metrics for system health and model performance monitoring
Logs for granular debugging and fine-tuning insights
Generic events for business telemetry and custom workflows
Session replays for UX and conversation analysis
Feature flags for controlled experimentation and model rollouts

Core Technology Stack

OpenTelemetry for standardised, high-quality, & battle-tested telemetry.
Rust for ultra-low-latency ingestion, processing, and fault tolerance
Apache Arrow for in-memory, zero-copy analytics
Apache Parquet for compact, query-optimized long-term storage with incremental writes
DataFusion for powerful SQL-based cross-signal and cross-model correlations

Key Features & Advantages

AI & LLM performance tracking — monitor token usage, cost per request, latency, and output quality in real time
Deterministic output assurance — correlate input prompts, context, and output variations to stabilize agent behavior
Multi-tenant isolation with Hive-style partitioning for secure, efficient organization
Edge-optimized OTLP exporters for low-latency, lossless signal forwarding
Schema-aware pipelines that adapt to evolving AI and product telemetry
Real-time + historical analytics in one unified interface
Type-safe instrumentation wrappers for SvelteKit, Python, Go, Rust, Cloudlfare Workers, and any backend services
Unified correlation engine — connect traces ↔ logs ↔ metrics ↔ events ↔ replays ↔ AI outputs in one timeline
State-of-the-art cost efficiency — thanks to our Rust + Arrow + DataFusion core, you get High value insights at a fraction of the cost

By collapsing fragmented observability stacks into a blazingly fast, cost-efficient, and AI-ready platform, O11y One transforms how teams monitor, debug, and improve both software systems and AI agents — making it easier to ship faster, run cheaper, and deliver reliably.
