YOUR DATA.YOUR AI.YOUR EDGE.
Capture agent trajectories, trace LLM tool calls, and analyze conversation patterns in real-time. Cookieless by default, ClickHouse-powered, and 100% self-hosted.
See Helion in action
A real dashboard, real data, no account required. Explore funnels, retention curves, and user profiles — then self-host your own.
Built for the AI era. Not retrofitted for it.
AI-native from day one
Every event you capture is structured for AI consumption. Feed your agents, fine-tune your models, and build LLM-powered features on top of real user data — not sampled exports.
You own the infrastructure
Self-host on your own cloud or bare metal. Your data never touches our servers. No vendor lock-in, no surprise price increases, no terms-of-service changes that affect your access.
ClickHouse at the core
Billions of events, sub-second queries. The same engine powering analytics at scale — running on your hardware, tuned for your workload.
AGPL-3.0. Fully open.
Read every line. Audit the data pipeline, the ingestion logic, the storage layer. No black boxes, no telemetry you didn't consent to, no proprietary SDK phoning home.
Cookieless by architecture
Not 'cookieless mode' buried in settings — cookieless by default. GDPR, CCPA, and ePrivacy compliant without consent banners slowing down your funnel.
Developer-first SDK
Type-safe. Tree-shakeable. Works in React, Next.js, Vue, Svelte, Node, and more. Ship a tracking event in under 5 minutes. No analytics consultant required.
Let your AI reason over your users
Connect Claude, Gemini, OpenAI, or any MCP-compatible agent to your Helion instance. Ask questions in natural language. Get ClickHouse-powered answers — from your own infrastructure.
Every event. Instant clarity.
See metrics and events stream in real-time. Unsampled data straight from ClickHouse, ready for ingestion and monitoring.
Built for teams shipping AI products
Three capabilities nobody else ships together: agentic querying, privacy by architecture, and a five-minute self-host.
Your AI queries funnels, cohorts & retention in natural language
No SQL, no dashboards to wire up. Your agent reasons over the raw event stream and returns answers — grounded in your own ClickHouse instance.
No consent dialogs
Privacy-compliant identity without cookies. GDPR and ePrivacy ready out of the box.
One command
Bring up the full stack — API, worker, ClickHouse — on your own infrastructure.

Principles behind Helion
Click on any principle card to expand its technical philosophy and architectural reasoning.
Telemetry is the ultimate context window. Build your AI features on raw user events, not sampled summaries.
If you don't own the database, you don't own your analytics. Keep your logs where they belong: your own infra.
Privacy is an architectural choice, not a settings toggle. Cookieless by default is the only sustainable path.
The fastest query is the one you don't have to wait for. ClickHouse database powers every dashboard at sub-second speeds.
Open-source is a trust framework. Inspect the ingestion logic, audit the database schema, and deploy with confidence.
Startups shouldn't be penalized for growing. We believe in unlimited websites, users, and dashboards.
