Why self-hosting matters
Every event your users generate is a signal. That signal belongs to you — not a SaaS vendor.
Helion was built from the ground up with a single conviction: analytics infrastructure should be owned by the team that builds the product. When you self-host Helion on your own VPS or cloud instance, your event data never leaves your control. There is no third-party ingestion layer, no SaaS vendor holding your historical data hostage, and no subscription cliff to fall off.
In the AI era, event telemetry is not just a reporting tool — it is a training signal. Teams are using behavioral data to fine-tune recommendation models, power autonomous agent workflows, and drive product decisions without asking permission from a vendor dashboard. Self-hosting Helion gives you native SQL access to your ClickHouse event store from day one.
You Own The Data
Every event lands in your ClickHouse instance. Export it, query it, delete it — on your schedule, not ours.
Zero Vendor Tax
No per-seat pricing, no event volume tiers, no feature paywalls. The full platform is yours when self-hosted.
GDPR-Native by Design
Data never crosses jurisdictional boundaries you didn't choose. Your VPS, your region, your compliance posture.
Everything included, no tiers
Self-hosted Helion is the full platform. There is no enterprise edition hiding behind a paywall.
Unlimited Event Volume
No monthly event caps. Ingest as much telemetry as your infrastructure can handle — ClickHouse is built for petabyte scale.
Full Analytics Suite
Funnels, cohort retention grids, custom dashboards, real-time active users, UTM tracking, and session profiles — all included.
Unlimited Team Members
Invite your entire engineering and product team. Role-based access with no per-seat pricing.
MCP Server Integration
Query your event data directly from AI agents via the Helion Model Context Protocol server. Your LLMs, your data, zero middleware.
SDK for Every Stack
JavaScript, TypeScript, React, Next.js, Astro, Python, iOS, Android — track events from any surface without cookies.
AGPL-3.0 Source Access
Every line of code is public on GitHub. Audit it, fork it, extend it. No black boxes in your analytics pipeline.
