YOUR DATA.YOUR AI.YOUR MOAT.
Open-source analytics built for agentic AI. Self-hosted. Cookieless. AGPL-3.0.
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.
Week-1 retention dropped 12% on March 4th, correlated with the pricing page change. Users who hit the new paywall before activating churned 2.3× faster.

Every event. Instant clarity.
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.
